Meat quality traits are economically important because they affect consumers' acceptance, which, in turn, influences the demand for beef. However, selection to improve meat quality is limited by the small numbers of animals on which meat tenderness can be evaluated due to the cost of performing shear force analysis and the resultant damage to the carcass. Genome wide-association studies for War...

Effects and interactions of calpain-system tenderness gene markers on objective meat quality traits of Brahman (Bos indicus) cattle were quantified within 2 concurrent experiments at different locations. Cattle were selected for study from commercial and research herds at weaning based on their genotype for calpastatin (CAST) and calpain 3 (CAPN3) gene markers for beef tenderness. Gene marker s...

Escherichia coli O157:H7 and Salmonella are significant foodborne pathogens that can be found in the feces and on the hides of meat animals. When hides are removed during the harvest process, the carcass and subsequent meat products can become contaminated. Camels, cattle, sheep, and goats are harvested for meat in Riyadh, Saudi Arabia. The prevalence of E. coli O157:H7 and Salmonella are unkno...

Body measurement and meat quality traits play important roles in the evaluation of productivity in cattle; they are influenced by genetic and environmental factors. Recent studies have shown that LYRM1 is a novel gene related to obesity and may influence fat deposition. We screened for new polymorphisms in the bovine LYRM1 gene and analyzed their association with body measurement and meat quali...

BACKGROUND Toxoplasmosis is a worldwide spread disease. The present study examined the prevalence of Toxoplasma gondii infection among animals of edible meat (cattle and sheep) in Chaharmahal va Bakhtiari Province (Southwest of Iran) in 2012. Furthermore, we attempted for the first time to identify this parasite from the meat products in the province. METHODS The tongue, brain, femur muscle a...

A whole-genome scan was carried out in New Zealand and Australia to detect quantitative trait loci (QTL) for live animal and carcass composition traits and meat quality attributes in cattle. Backcross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. The New Zealand cattle were reared and finished on pasture, whilst Australian cattle were reared on grass ...

AIM Meat adulteration is a serious problem in the meat industry and needs to be tackled to ensure the authenticity of meat products and protect the consumers from being the victims. In view of such likely problem in indigenous meat products of Kashmiri cuisine (Wazwan), the present work was performed to study the detection of beef and buffalo meat in cooked mutton Rista by mitochondrial DNA (mt...

were passing meat inspection. Meat inspectors were requested to submit lymph nodes that appeared abnormal as to size, color, or consistency. A total of 2843 dairy animals3 and 6791 beef animals was inspected on collection days. Lymph nodes were submitted from 736 cattle. Four dairy cattle were found to have malignant lymphoma following the histopathologic study. Two of these cows with extensive...

In this study, we determined species-specific variations by analyzing the mitochondrial 12S rRNA gene sequence variation (∼440 bp) in 17 newly obtained sequences and 90 published cattle, yak, buffalo, goat, and pig sequences, which represent 62 breeds and 17 geographic regions. Based on the defined species-specific variations, two endonucleases, Alu I and Bfa I, were selected for species authen...
