Abstract
Studies on the housing system's impact on laying hens' intestinal microbiota were retrieved from the Web of Science, PubMed, and Scopus (between 2017 and 2022). Inclusion criteria were studies that discussed measurable effects related to the topic written in English, Portuguese, and Spanish. Of 3281 articles in the identification stage, 12 studies were used in the systematic review. Asia developed most research relating to the subject. Most studies compared the intestinal microbiota of laying hens from conventional cages versus Cage-Free or Free-Range. However, no study has evaluated the intestinal microbiota of laying hens maintained in an organic system. Greengene and Silva were the most used reference in the studies. According to the results observed in the studies included in the systematic review, there is greater alpha diversity in the alternative system and a high dissimilarity between the conventional and alternative systems. Exposure to environmental factors such as soil, vegetation, natural lighting, access to pastures, and ingesting fibrous foods can lead to changes in the intestinal microbiota. A brief outline of published scientific evidence demonstrates that the housing system can change the gut microbiome of hens. This study summarises the relationship between the housing system and the intestinal microbiome of laying hens and provides a roadmap for future research regarding the gut microbiome of hens.

Abstract
Cognitive difficulties are reported in up to 60% of people with MS (pwMS). There is often a discrepancy between self-reported cognitive difficulties and performance on cognitive assessments. Some of this discrepancy can be explained by depression and fatigue. Pre-MS cognitive abilities may be another important variable in explaining differences between self-reported and assessed cognitive abilities. PwMS with high estimated premorbid cognitive functioning (ePCF) may notice cognitive difficulties in daily life whilst performing within the average range on cognitive assessments. We hypothesised that, taking into account depression and fatigue, ePCF would predict (1) differences between self-reported and assessed cognitive abilities and (2) performance on cognitive assessments. We explored whether ePCF predicted (3) self-reported cognitive difficulties. Eighty-seven pwMS completed the Test of Premorbid Functioning (TOPF), the Brief International Cognitive Assessment for MS (BICAMS), self-report measures of cognitive difficulty (MS Neuropsychological Questionnaire; MSNQ), fatigue (MS Fatigue Impact Scale; MFIS) and depression (Hospital Anxiety and Depression Scale; HADS). Results revealed that, taking into account covariates, ePCF predicted (1) differences between self-reported and assessed cognitive abilities, p < .001 (model explained 29.35% of variance), and (2) performance on cognitive assessments, p < .001 (model explained 46.00% of variance), but not (3) self-reported cognitive difficulties, p = .545 (model explained 35.10% of variance). These results provide new and unique insights into predictors of the frequently observed discrepancy between self-reported and assessed cognitive abilities for pwMS. These findings have important implications for clinical practice, including the importance of exploring premorbid factors in self-reported experience of cognitive difficulties.

Abstract
Understanding what others are doing is an essential aspect of social cognition that depends on our ability to quickly recognize and categorize their actions. To effectively study action recognition we need to understand how actions are bounded, where they start and where they end. Here we borrow a conceptual approach - the notion of 'canonicality' - introduced by Palmer and colleagues in their study of object recognition and apply it to the study of action recognition. Using a set of 50 video clips sourced from stock photography sites, we show that many everyday actions - transitive and intransitive, social and non-social, communicative - are characterized by 'canonical moments' in a sequence of movements that are agreed by participants to 'best represent' a named action, as indicated in a forced choice (Exp 1, n = 142) and a free choice (Exp 2, n = 125) paradigm. In Exp 3 (n = 102) we confirm that canonical moments from action sequences are more readily named as depicting specific actions and, mirroring research in object recognition, that such canonical moments are privileged in memory (Exp 4, n = 95). We suggest that 'canonical moments', being those that convey maximal information about human actions, are integral to the representation of human action.1.

Abstract
AbstractThis study aimed to compare and evaluate the effects of different protein coatings on maintaining the quality of eggs stored for six weeks at 20 °C. 308 brown table eggs from ISA Brown hens were used for four treatments: uncoated eggs, coated with rice protein concentrate – RPC, soy protein concentrate – SPC, and whey protein concentrate – WPC. Eggs started with Haugh Units (HU) of 82.01 and reduced in proportions of 28.75% (control), 12.82% (RPC), 12.90% (SPC), and 10.54% (WPC) on the last day of storage. Coated eggs showed smaller reductions (P < 0.0001) in this response. Protein coatings can effectively maintain the quality of eggs stored for six weeks at 20 °C. However, the WPC coating maintained the highest egg rate and the best yolk index for eggs stored for six weeks at 20 °C.

Abstract
Abstract
Background
Ethics are the set of moral principles that guide a person’s behaviour. Ethical issues are a key component of healthcare and frequently arise in the management of hospitalized older patients. To improve decision-making and reduce burden on individual hospital staff, Clinical Ethics Support Services (CESS) have been widely-integrated into care pathways internationally. However, the need for CESS has received little attention in Irish hospitals.
Methods
A cross-sectional analysis of the ethical situation and CESS readiness at a tertiary hospital in Ireland was collected from July-October 2021 and in February 2022 via hard copies and online collection (SurveyMonkey). Both clinical (medicine, nursing other patient care role) and non-clinical (administrative, clerical, ICT, HR, general support staff and management) staff participated. Descriptive statistics were assessed taking the valid percentages, mean 5-item Likert scores and Friedman Test mean rank for ten ranked statements.
Results
In total, 199 people (13% response rate) completed the survey. Staff were largely (76%) clinical and the majority were qualified >10 years (57%). In all, 78% reported that ethical issues arise in the role (83% clinical staff, 59% non-clinical staff). Most (63%) were unsure who to contact about ethical concerns, instead seeking informal advice from colleagues (>90%). The majority of participants were interested in additional ethical training, especially on decision-making capacity (mean interest 4.18 out of 5), strategies for working with challenging patient/family situations (4.07 out of 5) and end-of-life care (4.06 out of 5). Out of ten options assessed, participants preferenced the development of a formal clinical ethics committee over education and training or the provision of educational materials.
Conclusion
Ethical issues commonly arise when caring for older hospitalized patients. This study found a perceived need and widespread interest in additional education as well as formal approaches to develop a hospital-based CESS, centred around a formal committee structure.

Abstract
Abstract
Background
Hip fractures are a significant cause of morbidity and mortality amongst older adults. The Irish Hip Fracture Database Standard 5 requires that all patients with hip fracture have a bone health assessment completed; most are commenced on bone protection therapy (BPT) to reduce future fractures. Communication to general practitioners (GPs) regarding long-term BPT is often incomplete and challenging to improve. We aimed to upgrade this communication process at discharge.
Methods
Initial audit was conducted assessing documentation of BPT after hip fracture in discharge letters to GPs. Subsequently we created a detailed BPT template for discharge letters containing clear information for GPs regarding medication initiation and advice for ongoing management. The template was introduced and doctors were educated on its use. We then re-audited discharge letters following this intervention. Patients included were over 60 years old with hip fracture. Patients deemed clinically unsuitable for BPT were excluded.
Results
Ninety discharge letters were reviewed, 45 at initial audit and another 45 after introducing the BPT template. Mean age was 80 years old, 66 (73%) were female. In the first audit cycle, 28/45 discharge letters (62%) briefly specified BPT. On repeating the audit cycle (following introduction of the discharge letter template) all 45/45 discharge letters (100%) clearly specified BPT. Most letters (41/45; 91%) included the detailed BPT template. Following this intervention all doctors reported increased awareness and understanding of BPT, and satisfaction with template use in discharge letters.
Conclusion
Effective implementation of a discharge letter template significantly improved communication to GPs regarding BPT following hip fracture.

Abstract
O objetivo deste estudo foi determinar se os parâmetros comportamentais, reprodutivos e de saúde podem diferir entre as porcas alojadas individualmente durante a gestação (Individual) ou alojadas em grupos entre os dias 3 a 5 (Grupo5) ou 38 a 42 (Grupo42) após a inseminação. Após a inseminação, 198 porcas de uma mesma granja comercial foram alocadas aleatoriamente em um dos três tratamentos, denominados sistema Individual, Grupo5 e Grupo42. Houve interação entre o sistema de alojamento e o tempo de gestação sobre os parâmetros comportamentais. A prevalência de porcas com comportamento ativo foi maior no sistema Individual do que nos sistemas em grupos. As porcas no sistema Individual apresentaram maior prevalência de comportamento exploratório do que as porcas no sistema Grupo5. As porcas no sistema Individual apresentaram menor prevalência de problemas de saúde, como vulva e lesões corporais e esterco no corpo, e maior prevalência de prolapso retal e constipação do que as porcas nos sistemas de grupos. As porcas no sistema Grupo42 apresentaram maior número de leitões nascidos vivos, total de leitões nascidos e menor período de gestação do que as porcas no sistema Individual. Menor número de fetos mumificados e maior número de natimortos e natimortos tipo 2 foram associados a porcas no sistema Grupo5. As porcas no sistema Grupo5 apresentaram redução de problemas de saúde, como prolapso retal e bursite e inflamação de pele, além de resfriados, e diminuíram o nível de estresse pois apresentaram maior expressão de comportamento social positivo e diminuição de comportamentos estereotipados, além de manterem os parâmetros reprodutivos semelhantes àquelas do sistema Individual.

Abstract
Brazilian hair sheep constitute a genetic diversity hotspot. These animals are found in the harsh environments of the Brazilian Northwest (semi-arid) region. Genotypes (50K SNP chip) from seven Brazilian sheep breeds (five hair and two coarse wool types) and 87 worldwide breeds were used to test for population structure, admixture and genetic diversity. Moreover, phylogenetic trees evaluating migration events between genetic groups were built. Brazilian Somali, a fat-tailed breed, had a close relationship with East African breeds and clustered distinctly from other Brazilian breeds. Brazilian Blackbelly and Barbados Blackbelly had a close relationship. The Morada Nova breed did not show close relationships with European or African breeds, revealing a single migration event from an Algerian hair breed. Brazilian Fat-tail and Morada Nova share a common ancestor, but the former showed introgressions from Brazilian Somali and Afrikaner breeds, explaining the fat-tail phenotype. The Santa Inês breed received a substantial contribution from Brazilian Bergamasca and showed an admixed origin with recent introgressions from other breeds, mainly from Suffolk. Furthermore, Brazilian Somali and Brazilian Fat-tail are the most endangered sheep genetic resources in Brazil and should be the focus for ex situ conservation programs. In conclusion, Brazilian hair sheep show an African origin and are characterized by diverse genetic composition, reinforcing the need for conservation of these genetic resources, and at the same time, this highly diverse group has variability that can be used in breeding programs.

Abstract
ABSTRACT The aim of this study was to evaluate the reproductive performance of sows in individual stalls (Stall) or group-housed into groups on days 3 to 5 (Pen5) or 38 to 42 (Pen42) after breeding. The reproductive data was collected from the operating system of the farm establishing the average of the weekly performances of the sows that gave birth, for four years, except for the Pen5 system, which was evaluated for three years. Statistical analyses were performed using SAS®, using MIXED (for quantitative traits), NPAR1WAY (for categorical traits) and LOGISTIC (binomial traits) procedures, using sows as a repeated measure. Sows in Stall system had piglets with higher birth weight them sows in the group-housed system (P<0.05), however the piglets born alive, total piglets weaned, average litter weight, and duration of farrowing were lower in this system than in the group-housed (P<0.0001). There was no difference between Pen5 and Stall systems for gestation period and mummified piglets. The Pen42 system had a higher percentage of mummified piglets and a shorter gestation period, when compared Pen5 and Stall systems (P<0.0001), and similar results to the Pen5 system for duration of farrowing, piglets born alive, stillbirths, total piglets weaned, average litter weight and birth weight (P<0.0001).

Abstract
ABSTRACT The objective of this study was to determine factors affecting phenotypic characteristics related to milk production and reproductive efficiency of dairy buffalo. Phenotypic records of 2,459 Murrah, Mediterranean and crossbred buffaloes from the Embrapa Eastern Amazônia herd, from 1969 to 2013 were used. Traits included: total milk production during lactation (TMP), milk production corrected for 305 days (P305); cow weight at calving (CW), fat milk percentage (F), age at first calving (AFC), calving interval (CI), calf birth weight (BW), as well as lactation (LP) and service periods (SP). Most traits were affected by genetic group as well as year and season or interaction between them. Genetic group affected F, CI, SP and CW. Very young and older cows showed poorer production traits. There was interaction between season and year for F, CI and CW. Correlations traits were generally medium to low. The principal component analysis showed that higher fat milk percentage was associated with higher percentage of Murrah breed, longer lactation period and older cows. Phenotypic characteristics in buffaloes reared in the Brazilian Amazon were significantly affected by genetic and management factors. This information can be used to help build sustainable production systems for the region and guide farmer decisions.

Abstract
Some livestock breeds face the challenge of reduced genetic variation, increased inbreeding depression owing to genetic drift and selection. Hybridization can reverse these processes and increase levels of productivity and adaptation to various environmental stressors. Samples from American Brangus were used to evaluate the indicine/taurine composition through nine generations (~45 years) after the hybridization process was completed. The purpose was to determine how hybridization alters allelic combinations of a breed over time when genetic factors such as selection and drift are operating. Furthermore, we explored genomic regions with deviations from the expected composition from the progenitor breeds and related these regions to traits under selection. The Brangus composition deviated from the theoretical expectation, defined by the breed association, of 62.5% taurine, showing taurine composition to be 70.4 ± 0.6%. Taurine and indicine proportion were not consistent across chromosomes. Furthermore, these non‐uniform areas were found to be associated with traits that were probably under selection such as intermuscular fat and average daily gain. Interestingly, the sex chromosomes were predominantly taurine, which could be due to the composite being formed particularly in the final cross that resulted in progeny designated as purebred Brangus. This work demonstrated the process of new breed formation on a genomic level. It suggests that factors like genetic drift, selection and complementarity shift the genetic architecture into a uniquely different population. These findings are important to better understand how hybridization and crossbreeding systems shape the genetic architecture of composite populations.

Abstract
ABSTRACT The objective of this study was to evaluate genetic aspects related to production and reproductive efficiency of Murrah and Mediterranean buffaloes and their crosses. A ranking of bulls from Embrapa Eastern Amazonia was also composed to guide assisted mating. Birth records of 2,322 Murrah, Mediterranean, and crossbred buffaloes from the Embrapa Eastern Amazon herd, from 1953 to 2013, as well as information on production and reproductive traits were used. Genetic analyzes were performed in the WOMBAT software using the animal model with two-trait analysis. While heritability (h2) for total milk production (TMP) and fat milk percentage (F) were generally high, for reproductive traits h2 tended to be low. Genetic correlations for TMP with the other traits were low and negative, except for TMP with calving interval (CI) and service period (SP) in the Mediterranean breed and with age at first calving (AFC) and SP in crossbred, which were positive and high. Bull 1001 had high predicted transmitting ability (PTA) for TMP, so it should transmit a greater volume of milk to his offspring, although it had a lower PTA for F. There was sufficient variability within the herd to work with genetic management for both production and reproductive efficiency.

Abstract
Existem diversas opções de genética de ovinos para os sistemas de produção, desde recursos genéticos locais (geralmente adaptados as condições ambientais) até raças especializadas. O cruzamento é uma alternativa para explorar a heterose e complementariedade entre as raças. Este estudo avaliou oito grupos genéticos obtidos a partir do cruzamento entre Santa Inês (SI), Poll Dorset (PD), Dorper (DO), East Friesian (EF), Primera (PR), and White Dorper (WD). SI e PD foram usados com raças paternas e maternas, enquanto as demais foram usadas apenas como raças paternas. Quarenta e oito cordeiros foram avaliados para altura da cernelha, perímetro torácico, comprimento do corpo e da garupa e espessura da pele, bem como peso de carcaça fria e peso dos cortes comerciais como pescoço, fralda, paleta, pernil, costela e lombo. Os animais Santa Inês demoraram mais tempo para atingir o peso de abate (30 kg) que as cruzas com Dorper e Poll Dorset. Os animais 87PDSI, 75PDSI e DOPD apresentaram maior peso dos cortes comerciais e maior rendimento de carcaça. O uso da raça Santa Inês, uma raça localmente adaptada, como raça maternal em sistema de cruzamento apresentou resultados similares ao uso de Poll Dorset, uma raça especializada para produção de carne. Esses resultados destacam a utilidade dos recursos genéticos locais em sistema de produção intensivo. Poll Dorset é a raça paterna recomendada para o cruzamento com matrizes Santa Inês em sistema de produção intensivo.

Abstract
Data from 294045 records from a crossbred Angus × Nellore population were used to estimate fixed genetic effects (both additive and non-additive) and to test different non-additive models using ridge regression. The traits studied included weaning gain (WG), postweaning gain (PG), phenotypic scores for weaning (WC) and postweaning (PC) conformation, weaning (WP) and postweaning (PP) precocity, weaning (WM) and postweaning (PM) muscling and scrotal circumference (SC). All models were compared using the likelihood-ratio test. The model including all fixed genetic effects (breed additive and complementarity, heterosis and epistatic loss non-additive effects, both direct and maternal) was the best option to analyse this crossbred population. For the complete model, all effects were statistically significant (P < 0.01) for weaning traits, except the direct breed additive effects for WP and WM; direct complementarity effect for WP, WM, PP and PM and maternal epistatic loss for PG. Direct breed additive effect was positive for weaning traits and negative for postweaning. Maternal breed additive effect was negative for SC and WP. Direct complementarity and heterosis were positive for all traits and maternal complementarity and heterosis were also positive for all traits, except for PG. Direct and maternal epistatic loss effects were negative for all traits. We conclude that the fixed genetic effects are mostly significant. Thus, it is important to include them in the model when evaluating crossbred animals, and the model that included breed additive effects, complementarity, heterosis and epistatic loss differed significantly from all reduced models, allowing to infer that it was the best model. The model with only breed additive and heterosis was parsimonious and could be used when the structure or amount of data does not allow the use of complete model.

Abstract
Dehorning is a common practice in cattle farming. Researchers suggest that pain during dehorning can be mitigated, although there is no conclusive evidence about the best technique and the best manner of pain relief. A systematic review-meta-analysis was performed to clarify the effect of dehorning on welfare indicators (cortisol concentration or average daily gain or vocalisation) in beef cattle up to 12 months of age. Five electronic databases were systematically searched, as well as conference proceedings and experts were contacted electronically. Pre-defined protocols were applied during all steps of the systematic review process. A random effect meta-analysis was conducted for each indicator separately with the mean of the control and treated groups. Four publications reporting seven studies and 69 trials were included in the MA involving 287 cattle. Heterogeneity between studies was observed for cortisol (I2
= 50.5%), average daily gain (I2
= 70.5%), and vocalisation (I2
= 91.9%). When comparing the non-dehorned group with amputation dehorning, the cortisol concentration was lower 30 min (P < 0.0001) and 120 min (P = 0.023) after procedure (0.767 nmol/L and 0.680 nmol/L, respectively). Local anaesthesia did not show a reduction in cortisol concentration at 30 min after dehorning by amputation. Non-dehorned animals had a tendency to decrease the number of vocalisation (P = 0.081; MD = 0.929) compared with the group dehorned by amputation. These results suggest that dehorning is a painful experience and that local anaesthesia did not alleviate short-term pain following dehorning. Further investigation into pain relief is required to improve confident decision making under practical conditions.

Abstract
O objetivo do presente estudo foi avaliar medidas morfométricas de bovinos da raça Crioula Lageana em diferentes idades, para estabelecer padrões de variação dessas medidas, contribuindo para a caracterização fenotípica da raça. Foram coletadas medidas corporais (comprimento corporal, altura da cernelha, perímetro torácico, altura da garupa, largura da garupa e comprimento de garupa) de 346 animais oriundos de três regiões do Planalto Catarinense (Campos de Curitibanos, Coxilha Rica e Campos de Caçador). As medidas morfométricas foram avaliadas em relação à idade, sexo e região de origem. A análise estatística foi realizada utilizando SAS versão 9.3. Os procedimentos utilizados incluíram análise de variância, correlações, cluster, discriminante e análise canônica. Foi observada diferença estatística entre machos e fêmeas para todas as medições, exceto altura da garupa, demonstrando o dimorfismo sexual. A altura da garupa variou até 3 e 5 anos de idade e comprimento do corpo variou em animais com mais de 11 anos de idade; enquanto a largura da garupa e perímetro torácico variaram até 7 e 9 anos de idade. Em média, 50% dos animais foram classificados correctamente, o que indica pouca diferença entre as regiões para as características morfométricas. Além disso, animais de Campos de Curitibanos foram os que apresentaram maior distância dos animais das outras regiões do planalto de Santa Catarina. As correlações entre altura da cernelha, largura e comprimento da garupa foram acima de 0,80. Assim, o comprimento da garupa pode ser considerado a medida mais adequada para avaliação do tamanho corporal desta raça, devido à alta correlação com as outras medidas e a facilidade de medição deste parâmetro.

Abstract
O objetivo do presente trabalho foi realizar uma análise de viabilidade populacional da raça bovina Crioula Lageana, para estudar seus parâmetros demográficos e genéticos, bem como verificar a interferência de fatores que podem afetar a sobrevivência eo desenvolvimento dessa população. A viabilidade da população foi estimada utilizando 128 cenários hipotéticos para avaliar o risco de extinção deste recurso genético, simulada por um período de 500 anos. Os resultados mostraram que a possibilidade de extinção desta raça durante os próximos 500 anos foi remota, mesmo em cenários menos favoráveis. A taxa de crescimento determinística (det.r) foi sempre positiva durante o período avaliado, sendo a mortalidade dos animais de até um ano de idade o fator mais importante que afetou este parâmetro. O tamanho da população aumentou rapidamente até atingir a capacidade de suporte da área (k), sendo este o principal fator limitante para o crescimento da população. O nível de heterozigose esperada (He) da população no pior cenário foi superior a 80% e o coeficiente de endogamia (F) foi inferior a 0,20 no final dos 500 anos de simulação. A análise da viabilidade populacional mostrou que a população de Crioula Lageana não apresentou risco aparente de extinção a longo prazo e que a capacidade de suporte da área é o principal fator limitante para o crescimento da população.

Abstract
O objetivo deste estudo foi prever os valores econômicos para características de produção, funcionais e de fertilidade, bem como para classificá-las em ordem de importância econômica para os sistemas de produção de leite no sul do Brasil. Para isso, dois grupos foram formados, de acordo com a sua produção, e as características consideradas foram: a produção de leite (L), a persistência da lactação (PL), a gordura do leite (GOR), a proteína do leite (PROT), a contagem de células somáticas (CCS), a idade de primeiro parto (IPP), o intervalo entre partos (IP), o consumo de ração (Consumo), a mortalidade (MORT) e o peso da vaca (PV). A receita baseou-se na venda de leite, de novilhas excedentes e de vacas de descarte, e os custos reais de operação foram utilizados para calcular o lucro e a margem bruta. A função de lucro utilizada para calcular os valores econômicos foi baseada em uma fazenda de 100 vacas. Os valores econômicos médios das características que afetam o lucro do produtor foram em ordem: GOR: US $ 3.776,07; PROT: US $ 1.888,03; L US $ 1.258,69, PL: US $ 1.258,69; PV: US $ 124,03; MORT: US $ -14,30; Consumo: US $ -614,01; IP: US $ -1.023,62; IPP: US $ -2.724,29; CSS: US $ -3.146,87. Os valores econômicos calculados para o volume de leite, fertilidade, qualidade do leite, resistência a doenças e consumo de ração, indicou que o uso dessas características como objetivos de seleção em programas de melhoramento deve resultar em aumento da rentabilidade para o produtor.

Abstract
The ability to predict the effects of climatic factors on animals and their adaptability is important for livestock production. The aim of the present study was to analyze whether existing indices are suitable for evaluating heat stress in Santa Ines and Morada Nova sheep, which are locally adapted hair sheep breeds from northeastern Brazil, and if the limits used to classify thermal stress are suitable for these breeds. Therefore, climatic, physiological, and physical parameters, as well as thermographic images, were collected in 26 sheep, 1 1/2 years old, from two genetic groups (Santa Ines 12 males and 4 females; Morada Nov. 7 males and 3 females) for 3 days in both morning (4:00 a.m.) and afternoon (2:00 p.m.) with six repetitions, totalizing 156 repetitions. Statistical analysis included correlations and broken-line regressions. Iberia and Benezra indices were the tolerance tests that best correlated with the assessed parameters. High correlations between environmental indices and rectal or skin surface temperatures was observed, which indicates that these indices can be used for Santa Ines and Morada Nova sheep raised in central Brazil. However, some indicative values of thermal discomfort are different from the existing classification. Therefore, in order to classify appropriately, the model used needs to be carefully studied, because these classifying values can vary according to the species and model. Further research is necessary to establish indicators of thermal stress for sheep breeds raised in the region.

Abstract
ABSTRACT The aim of this study was to evaluate the effect of different agricultural products on quantitative aspects of carcass, body constituents, cooking loss, shear force and colorimetry of the Longissimus lumborum and Triceps brachii muscles in Santa Ines lambs. 24 Santa Ines female lambs received one of four diets which were isoproteic and isoenergetic with fixed levels of forage (60%) and concentrate (40%) of corn and soybean meal during 45 days. The forages per diet differed: coast-cross hay (HAY), cassava hay (CASS), dehydrated by-product of pea crop (PEA) and sugarcane (SC). The average weight of the lambs at the beginning of the experiment was 26.35kg. Animals were slaughtered in a federally certified abattoir. Initial and final pH, cooking losses, color using the CIELAB system, shear force and the quantity of sarcomeres per 100μm were measured. Hot carcass, cold and half carcass weights were affected by treatments (P<0.05). The sarcomere length of Triceps brachii muscle 24 hours after slaughter differed between diets and coast-cross hay had the lowest value. The sarcomere length differed significantly between diets and the dehydrated by-product of pea crop had the lowest number of sarcomeres immediately after slaughter compared to other diets. There was no influence of diet on colorimetry, cooking loss and shear force. The decrease in pH followed the development of the process of rigor mortis in the Longissimus lumborum and Triceps brachii muscles in the first hour and up to 24 hours after slaughter. Diets did not alter the pH, water holding capacity, colorimetry or shear force. The pea by-product and sugarcane can replace traditional sources of fodder without depreciation of meat characteristics.

Abstract
No presente estudo objetivou-se determinar curvas de crescimento para quatro raças de suínos naturalizados do Brasil (Moura, Piau, Nilo e Monteiro) através de ajustes não lineares. Foram coletados dados de 13 medidas morfológicas de 220 exemplares de ambos os sexos entre os 30 dias de vida até a idade adulta. As curvas foram ajustadas usando regressão não linear, pelas equações de Gompertz, Weibull, Logística, Brody e Richards. A melhor função foi selecionada pelo maior R² e menor erro quadrático médio, sendo a função de Weibull a mais apropriada para todas as raças e sexos. No geral, as fêmeas de todas as raças atingiram as medidas adultas com mais precocidade, porém os machos cresceram mais do que as fêmeas. O crescimento da raça Moura é o que mais se assemelha ao crescimento das raças industriais, isso pode estar relacionado ao fato de grande parte dos exemplares serem criados em sistemas de engorda. Por outro lado, a raça Monteiro foi a que apresentou um crescimento mais tardio. Conclui-se que as raças de suínos naturalizados brasileiros possuem crescimento diferenciado, que está relacionado com a origem genética da raça e adaptação ao ambiente.

Abstract
Live fish movement is considered as having an important role in the transmission of infectious diseases. For that reason, interventions for cost-effective disease prevention and control rely on a sound understanding of the patterns of live fish movements in a region or country. Here, we characterize the network of live fish movements in the Irish salmonid farming industry during 2013, using social network analysis and spatial epidemiology methods, and identify interventions to limit the risk of disease introduction and spread. In the network there were 62 sites sending and/or receiving fish, with a total of 130 shipments (84 arcs) comprising approx. 17.2 million fish during the year. Atlantic salmon shipments covered longer distances than trout shipments, with some traversing the entire country. The average shipment of Atlantic salmon was 146,186 (SD 194,344) fish, compared to 77,928 (127,009) for trout, however, variability was high. There were 3 periods where shipments peaked (February-April, June-September, and November), which were related to specific stages of fish. The network was disconnected and had two major weak components, the first one with 39 nodes (mostly Atlantic salmon sites), and the second one with 10 nodes (exclusively trout sites). Correlation between in and out-degree at each site and assortativity coefficient were slightly low and non-significant: -0.08 (95% CI: -0.22, 0.06) and -0.13 (95% CI: -0.36, 0.08), respectively, indicating random mixing with regard to node degree. Although competing models also produced a good fit to degree distribution, it is likely that the network possesses both small-world and scale-free topology. This would facilitate the spread and persistence of infection in the salmon production system, but would also facilitate the design of risk-based surveillance strategies by targeting hubs, bridges or cut-points. Using Infomap community detection algorithms, 2 major communities were identified within the giant weak component, which were linked by only 4 nodes. Communities found had no correspondence with geographical zones within the country, which could potentially hinder the implementation of zoning strategies for disease control and eradication. Three significant spatial clusters of node centrality measures were detected, two in county Donegal (betweenness and outcloseness) and one in county Galway (incloseness), highlighting the importance of these locations as hot spots of highly central sites with a higher potential for both introduction and spread of infection. These results will assist in the design and implementation of measures to reduce the sanitary risks emerging from live fish trade within Ireland.

Abstract
The aim of this work was to evaluate the growth performance, carcass characteristics, 12th rib tissue composition, haematological and serum biochemical parameters, as well as the presence of gossypol residues in the meat of Santa Inês lambs fed cotton crop by-products. For an experimental period of 90 days, 24 intact male Santa Inês lambs (bodyweight (BW): 20.6 ± 1.9 kg; 4 months old) were fed a 50 : 50 forage : concentrate diets fed ad libitum. Chopped Coast cross (Cynodon dactylon (L.) Pers) hay was used as forage. The animals were then allocated into four treatments, according to the cotton crop by-product included in the concentrate formulation: Control (CON) – No cotton crop by-product used in formulation; Whole cottonseed (WCS); Cottonseed cake (CSC); and Cottonseed meal (CSM). The animals were weighed and blood collected every 15 days. At the end of the experimental period, the lambs were slaughtered and the evaluations of carcass characteristics, 12th rib tissue composition and presence of gossypol residues in the meat were carried out. Dry matter intake was higher (P < 0.05) for the diets containing cotton crop by-products, but BW gains were not different (P > 0.05). Despite these results the animals fed the highest level of gossypol (WCS) had lower (P < 0.05) carcass yield resulting in lower (P < 0.05) carcass weight, suggesting a possible negative effect of gossypol on carcass development. Serum urea was elevated on all treatments including CON, otherwise haematological and biochemical parameters were within reference ranges. No gossypol residues in meat were detected by the method used here, which had a minimum detection limit of 20 ppb. It is concluded that the cotton crop by-products may have impaired carcass production but did not leave gossypol residues in lamb meat.

Abstract
This study investigates the association of semen traits with boar fertility. The fertility outcome (farrowing rate - FR and total piglets born - TB) of 14 boars was obtained from a field trial conducted during 10 week of breeding period on a commercial farm using multiparous sows (n = 948) through single-sire mating with 2 × 10(9) motile sperm cells per artificial insemination (AI) dose. Sperm motion parameters, evaluated with computer-assisted semen analysis system in raw and stored semen at 17°C for 240 h, in addition to morphological sperm defects, measured on the collection day, were included in the analysis to determine which semen traits were important to discriminate the fertility potential of ejaculates from these boars. The data underwent multivariate cluster, canonical and discriminant analyses. Four clusters of boars were formed based on fertility outcome. One boar, with the lowest FR and TB values (89.7% and 11.98), and two boars, with the highest FR and TB values (97.8% and 14.16), were placed in different clusters. The other boars were separated in two distinct clusters (four and seven boars), including boars with intermediate TB (12.64 and 13.22) but divergent values for FR (95.9% vs 91.8%). Semen traits with higher discriminatory power included total motility, progressive motility, amplitude of lateral head displacement and cytoplasmatic droplets. Through multivariate discriminant analysis, more than 80% of the 140 ejaculates were correctly classified into their own group, showing that this analysis may be an efficient statistical tool to improve the discrimination of potential fertility of boars. Nevertheless, the validation of the relationship between fertility and semen traits using this statistical approach needs to be performed on a larger number of farms and with a greater number of boars.
