Influence of different feeding strategies on carcass and meat quality of grassfed cull cows

Animal performance, carcass and meat quality characteristics of beef cull cows under different feeding strategies were evaluated. Cows allotted to one four direct grazing treatments combining levels forage allowance (FA) supplementation rate (% live body weight, BW) using rice bran (RB): T1= FA2%+RB0, T2= FA4%+RB0, T3= FA2%+RB0.8% T4= FA2%+RB1.6%. from T1 presented lower (P<0.05) slaughter weight (SW) than the other three treatments. Additionally, for rump loin, striploin, sirloin, inside round tri-tip, compared T2, T3 T4. Intramuscular fat (IMF), pH (48 h), Warner-Bratzler shear force (WBSF; aged 7 or 21 days), lean colour, saturated fatty acid (SFA), monounsaturated acids (MUFA) polyunsaturated (PUFA) concentrations did not differ among (P>0.05). A strategic use low RB on an oats crop, improves both qualitry traits cows, adding value promoting healthy production human consumption grass-based systems.
