Miranda-de la Lama GC. Electro-thermal injuries in ruminants caused by electrical equipment during pre-slaughter operations: Forensic case reports from an animal welfare science perspective. Forensic Sci Int 2024; 356:111936. [PMID: 38290416 DOI: 10.1016/j.forsciint.2024.111936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 08/29/2023] [Accepted: 01/14/2024] [Indexed: 02/01/2024]
Abstract
The use of electrical equipment for herding and moving livestock (electric batons) or for stunning animals before slaughter (electric stunners) is widespread in the livestock and meat industries worldwide. The use of these equipment is restricted to specific procedures and/or exceptional circumstances that justify their rational use. However, these restrictions can be underestimated or disregarded due to ignorance, inexperience, incompetence or irresponsibility on the part of users, resulting in pain and suffering to the animals and, in some cases, electro-thermal injury. This report presents four forensic cases of electro-thermal injuries identified during post-mortem animal welfare assessments in slaughterhouses in Colombia, Mexico and Spain. Electro-thermal injuries caused by contact (accidental or intentional) of equipment electrodes with skin and subcutaneous tissue are presented. Although our cases are isolated events detected over a 5-year period, they provide a useful visual guide for technicians and veterinarians interested in the differential diagnosis between bruises and electro-thermal injuries. The differentiation of the equipment causing the injuries allows the identification and control of critical points for animal welfare along the pre-slaughter logistic chain and the elimination of inappropriate animal handling practices.

Traditional halal meat production without stunning versus commercial slaughter with electrical stunning of slow-growing broiler chicken: impact on meat quality and proteome changes. Poult Sci 2023; 102:103033. [PMID: 37708767 PMCID: PMC10506100 DOI: 10.1016/j.psj.2023.103033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 08/10/2023] [Accepted: 08/11/2023] [Indexed: 09/16/2023] Open
Abstract
Impact of traditional halal meat production without stunning (NST) and commercial slaughter with electrical stunning (ST) of 100 slow-growing broiler chicken on blood plasma and different biochemical, enzymatic, hormonal, meat quality, and proteomic changes was evaluated. The results revealed lower (P < 0.05) postmortem pH values and higher redness (a*) scores for ST samples relative to NST group. Myofibrillar fragmentation index and bleeding efficiency (%) were lower (P < 0.05) in ST compared to NST samples. The ST group had higher (P < 0.05) creatinine, total protein, alanine aminotransferase (ALT), and triiodothyronine (T3) than NST group, however, no difference (P > 0.05) in blood glucose, lactate dehydrogenase (LDH), creatine kinase (CK), thyroxine (T4), cortisol, and aspartate aminotransferase (AST) was observed relative to NST samples. The 2-dimensional gel electrophoresis (2-DE) coupled to MALDI-TOF MS of meat samples has identified 14 differentially abundant proteins between 2 groups. Proteins demonstrating positive correlation with stress namely adenylate kinase isoenzyme-1, Rho guanine nucleotide exchange factor (NST), and apolipoprotein A-I (ST) were overabundant. From the current study, it is concluded that electrical stunning of broilers prior to slaughter or traditional halal slaughter without stunning does not adversely affect the meat quality.

Abstract
1. This study evaluated the suitability of routine analytical procedures and used mass spectrometry-based proteomic approaches to distinguish meat from dead chicken/ cold-slaughtered birds (CS), electrically stunned and slaughtered birds, as per standard protocols (ES), and birds slaughtered according to halal guidelines (HS).2. Meat from CS birds had lower (P < 0.05) pH, water-holding capacity and higher (P < 0.05) lipid oxidation, haem iron content, residual blood and total viable counts relative to ES and HS meat indicating poor quality.3. The results demonstrated the presence of unique protein bands on SDS-PAGE only in CS meat that can be used for routine screening.4. Protein analysis using MALDI-TOF mass spectrometry identified haemoglobin subunit alpha-A and alpha-D; Adenylate kinase isoenzyme 1 as reliable and stable marker proteins for authentication of dead chicken meat under raw and cooked conditions and halal slaughtered chicken, respectively.5. The methods used may be employed by the food safety and regulatory agencies for regular screening of meat quality and to authenticate CS or HS chicken.

Meat Sci 2023; 202:109207. [PMID: 37150067 DOI: 10.1016/j.meatsci.2023.109207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/02/2023] [Accepted: 04/26/2023] [Indexed: 05/09/2023]
Abstract
Proteomics plays a key and insightful role in meat research in the post-genomic era. This study aimed to unveil using a shotgun proteomics approach the temporal dynamic changes in early post-mortem proteome of goat Semitendinosus muscle. Therefore, the evolution and comparison of the muscle proteome over three post-mortem times (1, 8, and 24 h) was assessed. The temporal proteomics profiling quantified 748 proteins, from which 174 were differentially abundant (DAPs): n = 55 between 1 h versus 8 h, n = 52 between 8 h versus 24 h, and n = 154 between 1 h versus 24 h. The DAPs belong to myriad interconnected pathways. Binding, transport and calcium homeostasis, as well as muscle contraction and structure, exhibited an equivalent contribution during post-mortem, demonstrating their central role. Catalytic, metabolism and ATP metabolic process, and proteolysis were active pathways from the first hours of animal bleeding. Conversely, oxidative stress, response to hypoxia and cell redox homeostasis along chaperones and heat shock proteins accounted for the large proportion of the biochemical processes, more importantly after 8 h post-mortem. Overall, the conversion of muscle into meat is largely orchestrated by energy production as well as mitochondrial metabolism and homeostasis through calcium and permeability transition regulation. The study further evidenced the role of ribosomal proteins in goat post-mortem muscle, signifying that several proteins experiencing changes during storage, also undergo splicing modifications, which is for instance a mechanism known for mitochondrial proteins. Overall, temporal proteomics profiling of early post-mortem muscle proteome offers an unparalleled view of the sophisticated post-mortem biochemical and proteolytic events associated with goat meat quality determination.

J Proteomics 2023; 276:104836. [PMID: 36764652 DOI: 10.1016/j.jprot.2023.104836] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 01/30/2023] [Accepted: 01/30/2023] [Indexed: 02/11/2023]
Abstract
Sheep meat (encompassing lamb, hogget and mutton) is an important source of animal protein in many countries, with a unique flavour and sensory profile compared to other red meats. Flavour, colour and texture are the key quality attributes contributing to consumer liking of sheep meat. Over the last decades, various factors from 'farm to fork', including production system (e.g., age, breed, feeding regimes, sex, pre-slaughter stress, and carcass suspension), post-mortem manipulation and processing (e.g., electrical stimulation, ageing, packaging types, and chilled and frozen storage) have been identified as influencing different aspects of sheep meat quality. However conventional meat-quality assessment tools are not able to elucidate the underlying mechanisms and pathways for quality variations. Advances in broad-based analytical techniques have offered opportunities to obtain deeper insights into the molecular changes of sheep meat which may become biomarkers for specific variations in quality traits and meat authenticity. This review provides an overview on how omics techniques, especially proteomics (including peptidomics) and metabolomics (including lipidomics and volatilomics) are applied to elucidate the variations in sheep meat quality, mainly in loin muscles, focusing on colour, texture and flavour, and as tools for authentication. SIGNIFICANCE: From this review, we observed that attempts have been made to utilise proteomics and metabolomics techniques on sheep meat products for elucidating pathways of quality variations due to various factors. For instance, the improvement of colour stability and tenderness could be associated with the changes to glycolysis, energy metabolism and endogenous antioxidant capacity. Several studies identify proteolysis as being important, but potentially conflicting for quality as the enhanced proteolysis improves tenderness and flavour, while reducing colour stability. The use of multiple analytical methods e.g., lipidomics, metabolomics, and volatilomics, detects a wider range of flavour precursors (including both water and lipid soluble compounds) that underlie the possible pathways for sheep meat flavour evolution. The technological advancement in omics (e.g., direct analysis-mass spectrometry) could make analysis of the proteins, lipids and metabolites in sheep meat routine, as well as enhance the confidence in quality determination and molecular-based assurance of meat authenticity.

Abstract
Goat meat, as a superior product including low lipids, low cholesterol contents and high-quality proteins, becomes the superior food for the national market. With the increasing demand for goat meat, the production, sensory quality and physicochemical properties of goat meat are also widely observed. Following significant discoveries on the mechanism determining goat meat quality, further research on complex and interactive factors leading to changes of goat meat quality is increasingly based on data-driven "omics" methods, such as lipidomics, which can rapidly identify and quantify >1000 lipid species at same time facilitating comprehensive analyses of lipids in tissues. Molecular mechanism and biomarkers indicating the changes of goat meat quality, authentication, meat analogue, nutrition and health by lipidomics are feasible. According to the analysis results of the classes and of different biomarkers lipids of goat meat quality, the main processes involved the biosynthesis of unsaturated fatty acids, associations with lipids and proteins, lipid oxidation, lipid hydrolysis, lipid degradation, lipid deposition and lipid denaturation, which have been translated into advanced technologies for identifying the goat meat adulteration and faux meat rapidly and accurately. SIGNIFICANCE: In this review, the research of lipidomics technology, past applications, recent findings and common on the recent advances of lipidomics in the quality assessment of mutton products by lipidomics with MS approaches have been summarized. The information reported in review can serve as a reference to characterize the lipids found in mutton, clarify the application of lipidomics to the field of mutton products and provide new perspectives in producing superior quality mutton products.

Abstract
BACKGROUND While most cattle and sheep in the United Kingdom are stunned before slaughter, non-stun methods are permitted to supply meat to specific consumers. This study aimed to identify the existing literature that compared animal welfare indicators during stun and non-stun slaughter, using a scoping review framework. METHOD Following a structured search strategy, including the establishment of a PICO (population, intervention, comparator and outcomes) question, a comprehensive literature search of the CAB Abstracts, MEDLINE and PubMed databases, was conducted. A total of 962 papers were identified, of which 16 were selected for data extraction. RESULTS Fourteen papers concluded that welfare at slaughter was negatively impacted at non-stun slaughter in comparison to stun slaughter; two papers were inconclusive. Welfare indicators identified included biochemical parameters, brain activity and visual signs of consciousness. Limitations regarding inconsistent restraint method, neck cut position and non-standardised measures of welfare at slaughter are highlighted. CONCLUSIONS This study provides further evidence that stunning is an effective method to improve the welfare of sheep and cattle at slaughter. Animal welfare advisors, politicians, religious communities and others interested in animal welfare could use the findings to further discuss and establish new dialogues for producing updated guidance on animal welfare at slaughter.

Abstract
A bakery is a business that bakes flour-based foods, including bread, cookies, cakes, pastries, and pies, and sells them. Some bakeries are also categorized as large scale, medium scale, and small scale. Halal embraces all food category; bakery product can satisfy the challenge and opportunity of halal food segment market. The small-scale bakery will benefit from creating a halal certification to attract new customers. The first stage of submission for halal certification is identifying Halal Control Points (HCP) of materials and production. The material tracing uses a decision tree. The purpose of this study is to identify HCP in materials and production processes and provide alternative improvements. Identification of HCP in material decision trees to determine contains non-HCP (halal) material, HCP material, and haram (forbidden) material. Happy Cake bakery uses 75% non-HCP (halal) materials and 25% HCP (noncertified halal) materials from 80 ingredients. Bakery Canggi Fully has 83.3% halal materials and 16.6% noncertified halal materials from 24 ingredients. Bakery MacCheese has 79% of halal materials and 21% of noncertified halal materials from 43 ingredients. The decision tree makes it very easy to identify the halal status of ingredients. The HCP ingredients need to be replaced with clearly halal ingredients. Substitution of HCP material to halal-certified ingredients may affect production costs, product quality, and profit. Therefore, it is necessary to choose a suitable halal material. Halal certification requires a high commitment of small-scale bakery businesses.

Abstract
:
Proteomic tools were extensively used to understand the relationship between muscle
proteome and conversion of muscle to meat, post-mortem proteolysis, meat texture, and variation
in meat color. Developments in proteomic tools have also resulted in their application for addressing
the safety and authenticity issues including meat species identification, detection of animal byproducts,
non-meat ingredients and tissues in meat products, traceability, identification of genetically
modified ingredients, chemical residues and other harmful substances. Proteomic tools are also
being used in some of the potential areas like understanding the effect of animal transportation,
stunning, slaughter stress, halal authentication and issues related to animal welfare. Emerging advances
in proteomic and peptidomic technologies and their application in traceability, meat microbiology,
safety and authentication are taking a major stride as an interesting and complementary alternative
to DNA-based methods currently in use. Future research in meat science need to be
linked to emerging metabolomic, lipidomic and other omic technologies for ensuring integrated
meat quality and safety management. In this paper, a comprehensive overview of the use of proteomics
for the assessment of quality and safety in the meat value chain and their potential application
is discussed.

Abstract
Advancements in technology and analytical methods enable researchers to explore the biochemical events that cause variation in meat quality. Among those, western blot techniques have been successfully used in identifying and quantifying the key proteins that have critical functions in the development of meat quality. Housekeeping proteins, like β-actin, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), and tubulins are often used as internal controls in western blots to normalize the abundance of the protein of interest. However, there are increasing concerns about using housekeeping proteins for western blot normalization, as these proteins do not demonstrate any loading differences above the relatively small total protein loading amounts of 10μg. In addition, the interaction between these housekeeping proteins and programmed cell death processes highlights the concerns about using the housekeeping protein as the internal control in meat quality research. Moreover, recent proteomic research has indicated that the abundance of some housekeeping proteins, like β-actin, GAPDH, and tubulin, can be altered by preslaughter stress, dietary supplementation, sex, slaughter method, genotype, breed, aging period, muscle type, and muscle portion. Furthermore, these housekeeping proteins could have differential expression in meat with differing color stability, tenderness, and water holding capacity. Therefore, this review aims to examine the realities of using housekeeping proteins as the loading control in meat quality research and introduce some alternative methods that can be used for western blot normalization.

Abstract
The commercial production of halal and kosher meat and controversy surrounding the slaughter without stunning is rapidly growing across the globe. Huge global market for halal and kosher meat warrants conciliation of religious practices and animal welfare for the betterment of meat industry. In the present study, we investigated changes in muscle proteome of sheep (Ovis aries) subjected to either electrical stunning and slaughtering or slaughter without any stunning (halal). The 2DE gel analysis detected approximately 377 protein spots in which 243 (119 up regulated and 124 down regulated) protein spots were significantly (p ≤ 0.05) differentially expressed with a fold change ratio ≥1.5/≤1.5. The in-gel digestion and MALDI-TOF/TOF MS analysis of statistically significant protein spots revealed 35 differentially abundant proteins out of which 26 were up-regulated and 9 were down-regulated. The study demonstrated that slaughtering of sheep without stunning resulted in changes in the abundance of proteins involved in catalytic, structural, and stress related processes. This understanding of protein alterations in sheep slaughtered with and without stunning have the potential to act as possible signature for animal welfare index.

[PMID: 33803498 PMCID: PMC8002871 DOI: 10.3390/ani11030858] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 01/04/2021] [Accepted: 01/08/2021] [Indexed: 01/05/2023] Open
Abstract
Simple Summary In smallholder communal farming systems, Nguni people slaughter goats using indigenous methods which have cultural and spiritual significance to them. Nguni wethers were slaughtered using the transverse neck incision (TNI), suprasternal notch (SNP) and under the shoulder blade at the chest floor point of elbow piercing (CFP) to the direction of the heart to assess meat physico-chemical characteristics parameters. Nguni wethers slaughtered with the TNI and CFP methods produced meat with an acceptable appearance similar to goats slaughtered with the conventional standard procedures. Abstract To improve goat meat quality in rural communities, it is important to evaluate the effects of indigenous slaughter methods used by resource-limited farmers when performing traditional ceremonies on the meat physico-chemical characteristics. The current study assessed the effects of the meat physico-chemical characteristics of Nguni goats slaughtered with the transverse neck incision (TNI), suprasternal notch piercing (SNP) and the under shoulder blade piercing at the chest floor point of elbow (CFP) to the direction of the heart methods. Thirty Nguni weathers were randomly assigned to three slaughter treatments (10 goats/treatment). Musculus longissimus thoracis et lumborum (LTL) was sampled at post-mortem for physico-chemical characteristic measurements. Meat from wethers slaughtered with the SNP method had greater ultimate pH values than meat from wethers slaughtered with TNI and CFP slaughter methods. Wethers slaughtered with the SNP method had lower meat redness (a*), yellowness (b*), and chroma (C*) values than those slaughtered with TNI and CFP slaughter methods. Goat slaughter method did not affect meat drip loss, water holding capacity, cooking loss and shear force. Overall, Nguni wethers slaughtered with the TNI and CFP methods produced chevon with fresher meat appearance than those slaughtered using the SNP method.

Abstract
Context
Breeds of buffalo (Nili-Ravi and Kundhi) show different growth-rate and meat characteristics. Consumer preferences vary for the selection of meat according to the taste and sensory attributes. Buffalo meat is widely consumed in Asia and multiple buffalo breeds are reared for meat production.
Aims
The current experiment was designed to compare growth rates, meat characteristics and consumer preference for meat from bulls of different buffalo breeds.
Methods
Thirty-five male Nili-Ravi buffalo bulls (NRBB) and 35 male Kundhi buffalo bulls (KBB) having an age of 18 ± 1.56 months and 18 ± 1.65 months with live bodyweight of 150 ± 1.98 kg and 149 ± 2.09 kg respectively, were purchased and reared for 90 days. All animals were slaughtered on the 91st day and samples from M. pectoralis descendance, M. latissimus dorsi and M. obliquus externus abdominis were collected. A consumer preference survey was also conducted to assess the preferences for meat from the buffalo breeds.
Key results
Results of the survey suggested that for buyers, meat colour was the primary selection criteria (P < 0.05) at the time of purchase. Consumers preferred the lighter-coloured meat of KBB (P < 0.05) than that of NRBB.
Conclusions
Findings of the study showed that meat from KBB had superior sensory attributes compared with NRBB, although the meat from NRBB was the more nutritious of the two buffalo breeds.
Implications
The results will provide a focussed view regarding selection of buffalo bulls for meat production.

Abstract
RESUMO O objetivo deste estudo foi avaliar as implicações sobre o bem-estar animal e a eficiência da sangria no abate halal com e sem insensibilização em ovinos. Foram avaliados 102 ovinos, em abate comercial, separados randomicamente pelo peso em dois grupos: com insensibilização (CI) e sem insensibilização (SI). Verificou-se que os animais sem insensibilização apresentaram sinais de endireitamento e vocalização após 20 segundos da degola. Houve diferença significativa para hemácias (P<0,01), hemoglobina (P<0,01), leucócitos totais (P<0,001), bem como para os biomarcadores de estresse, como CK (P<0,01) e lactato (P<0,001). Apesar de não apresentarem diferença estatística significativa, o LDH e o cortisol ficaram acima dos valores basais em ambos os grupos. Não foram observadas alterações séricas para glicose e AST. Houve diferença estatística significativa para eficiência da sangria (P<0,01). Os resultados demonstraram que houve estresse no abate halal com e sem insensibilização e melhor eficiência da sangria em animais não insensibilizados.
