Abstract
The aim of the study was to evaluate the effect of water restriction and low- and high-energy diets on sheep's thermoregulatory responses and ingestive behavior. Forty sheep, non-castrated, with an average body weight of 18.85 kg (SD = 2.80 kg) and an average age of 5 months were assigned to a 2 × 2 factorial arrangement, comprising 2 diets (high- and low-energy) and 2 water offers (ad libitum and 50% water restriction), with 10 replicates. Thermoregulatory responses were evaluated in two periods (morning and afternoon). There was an interaction effect of Diet x Water supply x Periods on respiratory rate (P < 0.05). High-energy diets resulted in increased heart rate, idleness, dry matter feeding and rumination efficiency, and water intake. Low-energy diets increased feeding time, rumination time, the number of ruminal cuds, chews per day, total chewing time, neutral detergent fiber intake and rumination efficiency, number of ruminations per day, average duration of rumination, and defecation frequency. Water supply affected heart rate and idleness (P < 0.05). Sheep had higher values of heart rate and rectal and surface temperatures during the afternoon (P < 0.05). Water restriction combined with a low-energy diet and high environmental temperature leads to a reduction in the respiratory rate of Santa Inês crossbred sheep. Regardless of the dietary energy value, water restriction by 50% of the daily requirement of sheep reduces dry matter intake and increases idleness.

Abstract
The aim of this study was to evaluate the biochemical, hormonal, and hematological blood responses of native sheep subjected to five temperatures (20°, 24°, 28°, 32°, and 36 °C), using 24 sheep of the following breeds: Santa Inês (SI), Morada Nova (MN), Soinga (SO) and no defined racial pattern (NDRP), kept in collective pens inside the climatic chamber. The experimental design was completely randomized, in a 5 × 4 factorial scheme (5 temperatures and 4 breeds) with 6 animals of each breed at each temperature. There was interaction for urea (P < .0001), glucose (P < .0001), cholesterol (P < .0001), and magnesium (P < .0001) as a function of breed and air temperature. Urea (P = .001), glucose (P < .0001), triglycerides (P = .033), cholesterol (P = .004), and magnesium (P < .0001) showed differences according to breed. It was observed that T4 (P < .0001) and cortisol (P < .0001) showed an interaction between breed and temperature, while T4 (P = .001) and cortisol (P = .001) an effect of breed. The highest magnesium concentration was observed in MN, and the lowest was in NDRP, SO, and SI, which are statistically similar, and SI and NDRP are statistically similar. The hormones showed a significant effect (P < .0001) for temperature, where cortisol increased, and thyroid hormones decreased with increasing temperature. Temperatures of 32° and 36 °C contribute to changes in blood, hormone, and hematological biochemical responses of native sheep.

Abstract
The first objective of this study was to develop a thermal stress index for sheep based on environmental and animal data collected in a climate chamber under various environmental conditions. The second objective was to compare published indices of thermal comfort and the proposed index, testing them with the data from this study, with the objective of pointing out the most adequate index to be used by breeders when choosing management procedures. A total of 3024 data were obtained for the physiological variables of the sheep exposed to the eight thermal conditions in the climatic chamber and in ambient condition, kept three days in each thermal condition. A principal component analysis summarized the measurements of physiological variables into only one variable (y1). Using SigmaPlot software, multiple regression of y1 with the environmental variables and their combinations produced a number of indices. The equation chosen was the heat stress index for sheep, TSI = 24.153 - (0.0523*AT) + (0.746*BGT) + (4.104*Vp), with R2 = 0.668. The correlations presented high values, where these correlation values were assumed to indicate the efficiency of each index as indicators of the animals' response to the environment. Thus, it was assumed that the TSI presents a high efficiency.

Abstract
The objective of this research was to evaluate the thermal exchanges, physiological responses, productive performance and carcass yield of Guinea Fowl confined under thermoneutral conditions and under thermal stress. For the experiment, 96 animals were confined in 8 experimental boxes of 1 m2 of area, each, divided in equal numbers and placed inside two distinct climatic chambers, where the birds were distributed in a completely randomized design, with two treatments (air temperatures of 26 and 32 °C, respectively). For the collection of physiological responses and carcass yield 16 birds were evaluated and for the collection of data on feed and water consumption and productive responses, 48 birds per treatment were evaluated. The environmental variables (air temperature (AT), air relative humidity and wind speed), temperature and humidity index (THI), heat exchanges, physiological responses (respiratory rate, surface temperature, cloacal temperature and eyeball temperature), feed (FC) and water (WC) consumption and production responses (weight gain, feed conversion index and carcass yield) of the birds were evaluated. With the elevation of the AT, it could be noticed that the THI went from a thermal comfort condition to an emergency condition, where the birds lost part of their feathers, increased all physiological responses evaluated, and consequently, reduced by 53.5% the amount of heat dissipated in the sensible form and increased by 82.7% the heat losses in the latent form, increasing also the WC. ATs of up to 32 °C did not significantly affect the productive performance and carcass yield of the guinea fowl.

Abstract
Aviculture is a developed and important industry worldwide. However, it is an industry that produces solid waste such as bedding. As an attempt to reduce environmental impact and productive activity costs, beds are reused by several consecutive lots which can increase microorganism concentration and lead to unsanitary conditions. In this regard, it is essential to adopt a litter pre-treatment during the gap sanitary period between lots to avoid passing problems to the birds from the current flock to the subsequent flock and to guarantee the litter quality. Several factors must be considered to guarantee that there is minimal damage to chicken production. Therefore, this literature review aims to approach the main factors that affect the thermal comfort and chicken litter quality, as well as alternatives used as an alternative biological treatment to guarantee its reuse quality.

Abstract
The structure of the coat and integument of small ruminants reared in semi-arid regions have valuable characteristics that favor their adaptation to the region. The objective of this study was to evaluate the structural characteristics of the coat and integument and sweating capacity of goats and sheep in the Brazilian semi-arid region, using 20 animals, 10 of each breed, 5 males and 5 females of each species, grouped in a completely randomized design in a 2 x 2 factorial scheme (2 species and 2 genders) with 5 replicates. The animals were already being kept under the influence of high temperatures and levels of direct solar radiation before the day of the collections. At the time of the evaluations, ambient temperature was high, with low relative humidity. The pattern of epidermal thickness and sweat glands per body region was superior in sheep (P < 0.05), and the number of hair follicles and sweat rate were similar (P > 0.05) between the species. There was no difference (P > 0.05) in the evaluated characteristics between the genders, showing that they are not influenced by hormones. The morphology of the coat and skin of these animals showed a superiority of goats compared to sheep.

Abstract
The objective of this study was to evaluate the productive performance and carcass characteristics of confined Santa Inês sheep, fed different diets, in a Semiarid environment. Twenty whole sheep with 5 ± 0.5 months of age and 27 ± 2.0 kg were used, receiving two different diets for 72 experimental days, one composed of defatted soybean meal and the other of protein-enriched cactus meal. They were evaluated for different diets, consumption, production, carcass characteristics, morphometric measures and edible components. The experimental design was in randomized blocks with two treatments and 10 replications. Performance data and carcass characteristics were evaluated by analysis of variance and means compared by t test at 5% probability level using Statistical Analysis System [SAS]® (1999). Thus, the use of emulsified palm forage protein in the feeding of Santa Inês male lambs proved to be an excellent protein source when compared to the use of defatted soybean meal, since the results of performance and carcass characteristics were similar, being the use of this alternative source advised as it presents the best benefit-cost ratio.

Abstract
This study aimed to carry out bioclimatic zoning based on the historical series of climatic variables such as air temperature, maximum, minimum and relative humidity collected in six conventional meteorological stations in the state of Paraíba, Brazil and from this to determine whether or not the animals are in thermal comfort by comparing with the results obtained in scientific research in each mesoregion in the rainy and dry periods. Then based on this the comfort conditions for small ruminants in the rainy and dry seasons of the mesoregions of Paraíba were observed using data from the literature, and demonstrated in spatial distribution maps. The variables air temperatures, maximum and minimum and relative humidity varied throughout the state for the rainy season between 22 to 27, 18 to 21, 25 to 31ºC and 64 to 82%, respectively, and in dry season is 23 to 27, 28 to 35, 19 to 23ºC and 49 to 76%, respectively. However, it is concluded that raising sheep and goats is viable in all mesoregions of the state of Paraíba in both periods

Abstract
The objective of this study was to evaluate the physiological responses, ethology, and ingestive behavior of female Morada Nova sheep kept in a thermoneutral environment, after thermal stress and after consuming water with different levels of salinity. Thirty-six Morada Nova females with a mean age of 10.0 ± 2.0 months and a mean weight of 25.0 ± 3.0 kg were evaluated and distributed in a climatic chamber. The experimental design was completely randomized, with a factorial scheme of 2 (air temperature (AT)) × 3 (salinity levels (SLs)) and six replications. The sheep's physiological responses, ethology (day/night), and ingestive behavior were evaluated while they were subjected to ATs of 26.0 and 32.0 °C and SLs of 3.0, 6.0, and 9.0 dS/m. With elevation in AT, the animals experienced increased (P < 0.05) rectal temperatures (RTs), respiratory rates (RFs), and surface temperatures (STs) and exhibited reduced (P < 0.05) heart rates (HRs). When consuming water with an SL of 9.0 dS/m, a HR reduction (P < 0.05) was observed. Sleep behavior increased (P < 0.05) with the increase in SL during the day. Sleeping and drinking behaviors increased (P < 0.05), and the time of inactivity was reduced (P < 0.05) during the nocturnal period with increased SLs. With increased SLs, sheep consumed more water (P < 0.05) and reduced (P < 0.05) the number of regurgitated ruminal boluses per day (NRBD). Under the conditions of thermal stress (32.0 °C), sheep need to make physiological adjustments to maintain homeothermy. Water consumption of SLs up to 9.0 dS/m causes a higher state of dormancy in female Morada Nova sheep.

Abstract
A exposição a temperaturas elevadas restringe a produtividade animal, tendo em vista as mudanças fisiológicas e hormonais que podem ser ocasionados pelo estresse térmico, contudo os estudos bioclimatológicos servem como ferramenta fundamental para avaliar os efeitos climáticos sobre o comportamento fisiológico dos animais, contribuindo desta forma com a seleção de animais mais adaptados às condições climáticas do semiárido. O objetivo desta pesquisa foi avaliar os efeitos das diferentes temperaturas (25,7; 29,4 e 33,4 ºC) em câmara climática nas respostas dos gradientes térmicos, do hormônio cortisol e dos pontos das temperaturas superficiais médias em caprinos mestiços da raça Boer, utilizando-se seis caprinos ¾Boer + ¼SRD, com peso médio de 25+ kg. Foram estimados os gradientes térmicos TS-TA (Temperatura Superficial - Temperatura Ambiental), TR-TS (Temperatura Retal - Temperatura Superficial) e TR-TA (Temperatura Retal - Temperatura Ambiental), coletou-se amostras de sangue para avaliação e quantificação das concentrações plasmáticas de cortisol pelo método Enzyme Linked Immuno Sorlent Assay (ELISA) e calculadas as temperaturas superficiais com base em diferentes metodologias. O delineamento utilizado foi o inteiramente casualizado, com três tratamentos e seis repetições; os dados foram analisados por meio do SAS pela aplicação dos procedimentos GLM e Teste de Tukey (T <0,05) para as variáveis significativas. Contudo conclui-se que os gradientes térmicos TS-TA TR-TS e TR-TA decresceram à medida que a temperatura elevou-se, pela dificuldade de perda do calor sensível e latente ocasionada pela elevação da temperatura. Observa-se também que não houve alteração no nível de cortisol significativa estatisticamente, assim como não há influência da quantidade de pontos na análise da temperatura superficial média (TSM) de caprinos podendo ser realizada satisfatoriamente por meio da coleta de somente três pontos. Palavras-chave: ambiência, fisiologia, termorregulação.

Abstract
When a dysfunction occurs in any component of the stomatognathic system, temporomandibular disorders (TMD) may originate. The aim of this study was to compare the deviations, displacement and the execution speed of mandibular movements among asymptomatic participants and those with TMD. Convenience sampling was used; forty participants diagnosed by clinical evaluation following the Research Diagnostic Criteria for Temporomandibular Disorders were divided into three groups: arthropathy (GART, 10 participants, 40% men), myopathy (GMYO, 10 participants, 30% men), and the control group (CG, 20 asymptomatic participants, 25% men). Participants were asked to perform the movements of free maximal mouth opening and closing, right and left lateral excursions, and protrusion with sliding teeth contacts. The mandibular trajectory was recorded using opto-electronic devices tracking reflective markers placed in front of the 'soft tissue pogonion point'. The movements were analysed on the following axis: x - medial-lateral, y - vertical, z - antero-posterior. Significative differences were found in CGxGART - unassisted maximal mouth opening and closing projection on y-axis (OCY), CGxGMYO - unassisted maximal mouth opening and closing projection on x-axis (OCX), and in the measures Opening lateral deviation on x-axis (OLDX), closing lateral deviation on x-axis (CLDX) and in the measures of speed for both. In regard to GARTxGMYO, a significative difference was found in Protrusion lateral deviation on x-axis (PLDX) 'Conover-Iman Test of Multiple Comparisons Using Rank Sums' using Bonferroni correction (P < 0·05). In conclusion, the total opening movements in individuals with TMD tended to have higher deviation than in those asymptomatic individuals and a reduction in the speed of movements.

Abstract
O objetivo do trabalho foi avaliar a correlação entre medidas corporais (peso corporal e perímetro torácico) e circunferência escrotal de ovinos da raça Santa Inês com idade entre seis e sete meses. Foram estudados 54 machos, pertencentes à 3ª categoria segundo regulamento da ABSI (Associação Brasileira de Santa Inês). Os dados foram obtidos durante a mensuração dos animais, sendo determinados o peso corporal, o perímetro torácico e a circunferência escrotal. Os coeficientes de correlação foram positivos entre peso e circunferência escrotal e entre perímetro torácico e circunferência escrotal, porém, apenas o primeiro foi significativo, apresentando ainda, valor de médio a baixo. Conclui-se que as correlações entre circunferência escrotal e medidas corporais não são consenso entre autores, apresentado divergências significativas quanto aos coeficientes encontrados.
