Resumen de TI 09. Variation in bull carcass trats in grassfed water buffalo and cattle and correlations with valuable cuts, trimmed fat and bone percentage
Nelson Huerta Leidenz, D. Mansutti, Argenis Rodas Gonzalez
Cut-out tests were conducted with whole males of grass-fed cattle (n=58) and water buffalo (n=38) previously evaluated for 10 different carcass traits at different commercial slaughter houses of Venezuela. Finish score and fat thickness in buffalo carcasses varied less (32 % and 58 %, respectively) than in cattle counterparts (37 % and 88 %, respectively). However, the proportion of fat trimmed (FAT) from buffalo carcasses varied much more than that of cattle (136 % vs. 26 %). Only the round width (RW) in buffaloes and ribeye area (REA) and RW in cattle were associated (r2 55 %) in FAT from buffalo carcasses accounted for its direct relationship to round measurements, carcass weight, fat thickness and ribeye area, showing eligibility of these traits to predict FAT in bull carcasses from buffaloes.
