Carcass-value marketing systems continue to demand the efficient production of lean pork. Unfortunately, some swine genotypes which provide a high percentage of carcass lean also tend to produce carcasses which are poor in overall quality. An increased incidence of soft carcass fat, which is seen in some lean genotypes, has been associated with mechanized processing difficulties and decreased c...

The heritability of carcass quality traits and the genetic correlations between wool production and these carcass quality traits were estimated on 1216 Merino rams. The results showed that carcass quality traits are moderately heritable but pH appears to be lowly heritable. Yellowness and redness of L. dorsi had very low heritability estimate. Moderate negative genetic relationships were found ...

Brahman cattle are important in tropical regions due to their ability to tolerate excessive heat and parasites. However, Brahman cattle exhibit lower carcass quality characteristics when compared to Bos taurus breeds. The objective of this study was to evaluate potential associations between single nucleotide polymorphisms (SNPs) in six candidate genes for carcass quality and composition traits...

the objective of this study was to evaluate the efficiency of water pressure and concentration of dichloromethane after the evisceration system under the fecal decontamination of chicken carcasse  surfaces with and without apparent contamination. from a total of  322 carcasses, 50% were intentionally added chicken droppings in an area of more  than 2 cm2 and the rest of carcasses were kept with...

Carcass and price traits of 72,969 Hanwoo cows, bulls and steers aged 16 to 80 months at slaughter collected from 2002 to 2013 at 75 beef packing plants in Korea were analyzed to determine heritability, correlation and breeding value using the Multi-Trait restricted maximum likelihood (REML) animal model procedure. The traits included carcass measurements, scores and grades at 24 h postmortem a...

The present study was carried out to study the carcass and meat quality traits of two breeds of [New Zealand White (NZW) and Californian (CAL)] under environmental conditions in Egypt. Two hundred of NZW and CAL (100 rabbits of each bread of 50 males and 50 females) aged and slaughtered at 12 weeks .The following traits were recorded: body weight at slaughter age carcass weight, meat, fat and a...

Mediation of nutrition and environmental stressors through hormonal and physiological responses alters growth performance and lipid metabolism in nonruminants, resulting in substantial impacts on carcass lipid quality. Understanding and managing the factors that control carcass fat quality is a challenge for the swine industry yet provides opportunities to improve final carcass quality and prof...

Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex and batch), covariates (birth weight, cold carcass weight, and age), random effects (additive, litter ...

Interest and questions about the quality of beef are on the rise due to heightened awareness about the marketing of beef, from procurement and processing to consumer acceptance. Belatedly, producers are now beginning to receive information about the quality of the beef they produce. Consolidations among beef marketers have resulted in better communication between marketers and producers on carc...

A joint growth-carcass analysis was conducted to develop equations for predicting carcass quality traits associated with variation in growth path of crossbred cattle. During a four-year period (1994-1997) of the Australian "Southern Crossbreeding Project", mature Hereford cows (r = 581) were mated to 97 sires of Jersey, Wagyu, Angus, Hereford, South Devon, Limousin, and Belgian Blue breeds, res...
