Muscle transcriptome response to stress in bovine

The conditions to which cattle are subjected before slaughter (social isolation, transportation, deprivation of food and water) are sources of emotional and physical stress that may affect the nutritional and organoleptic qualities of meat from these animals. We have examined the muscle transcriptomes (m. Longissimus thoracis and the m. Semitendinosus) in cows exposed to stress vs cows with limited stress. Stress was a combination of emotional and physical stress. one-color experiment ; two groups of cows : finished and slaughtered under conditions of limited stress (n = 16) or physical and psychological stress (n = 16) ; 2 muscles studied : m. Longissimus thoracis (LT) and m. Semitendinosus (ST)
