The aim of this study was to assess the ability of electronic tongue system TS-5000Z to evaluate meat quality based on flavor assessment, recognition and correlation with the meat chemical composition. Meat was sampled from eighteen beef cattle including 6 Wagyu breed cattle, 6 Angus breed cattle and 6 Simmental breed cattle. Chemical composition including dry matter, crude protein, fat, ash, c...

background: toxoplasmosis is a worldwide spread disease. the present study examined the prevalence of toxoplasma gondii infection among animals of ediblemeat (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 an...

Body measurement and meat quality traits play important roles in the evaluation of productivity and economy in cattle, which are influenced by genes and environmental factors. PRKAG2, which encodes the γ2 regulatory subunit of AMPK, is associated with key metabolic pathways in muscle. We detected bovine PRKAG2 gene polymorphisms and analyzed their associations with body measurement and meat qua...

Aim: The objective of this study was to develop a simplified, efficient, and accurate protocol for sexing of cattle meat based on the amelogenin (AMELX/AMELY) gene using PCR technique which is superior to earlier work in terms of band patterns. Materials and Methods: Based on the amelogenin gene located on the conservation region of X and Y chromosomes, a pair of primers was designed and the sy...

Growth and meat quality traits play important roles in the evaluation of cattle productivity and are influenced by genetic and environmental factors. CRTC2 is a recently discovered gene related to obesity that may influence fat deposition. The aim of the current study was to detect polymorphisms of bovine CRTC2 and explore their relationships to growth and meat quality in Qinchuan cattle. Three...

By studying carcass quality, expressed as affection, pathological findings, slaughter-weight and evaluation, a picture of an animal's health and potential as high quality food is achieved. This study compares the carcass quality in Swedish certified organic meat production with that of conventional meat production slaughtered during 1997. The study involves 3.9 million pigs, about 570,000 cattl...

Proteomics allows studying large numbers of proteins, including their post-translational modifications. Proteomics has been, and still are, used in numerous studies on skeletal muscle. In this article, we focus on its use in the study of livestock muscle development and meat quality. Changes in protein profiles during myogenesis are described in cattle, pigs and fowl using comparative analyses ...

This research examines the returns to a cattle feeding operation that sorts animals prior to marketing using ultrasound technology. The returns to sorting are between $11 and $25 per head depending on the number of groups the pens in which cattle can be sorted. Sorting faces declining returns. These returns can also be viewed as the costs imposed by institutional constraints that limit co-mingl...

background: toxoplasmosis is a zoonotic disease, caused by cosmopolitan coccidian parasite, toxoplasma gondii. one of the most important sources of human infection is feeding from raw or uncooked meat of infected animals. in this study the prevalence of toxoplasmic infection in three important meat producing animals in iran was studied. methods: using indirect immunoflourcent antibody assay (if...

The studies were carried out on 614 animals slaughtered in winter and summer seasons. After slaughter and post-slaughter processing the carcasses were evaluated according to EUROP system. The meat pH and its colour were determined in m. longissimus thoracis after 48 hours of chilling. A significant effect of cattle category, season of slaughter and interactions between them on meat pH was found...
