INAC – CARCASS CHARACTERISTICS OF CROSSBREEDING BETWEEN BOS TAURUS AND BOS INDICUS BREEDS IN URUGUAY.
INAC – Abstract. The objective of this research was the study the genetic type effect on carcass quality of 245 steers from Hereford (H) and F1 crosses, breeding sires of Angus (A), Salers (S) and Nellore (N) breed mated to Hereford dams. They were slaughtered at 730± 52 days at similar fat thickness. The highest weight of carcass was found in SH (250.5 kg) and NH (244.5 kg), while the lowest in AH (232,1 kg) crosses and H (222.8 kg) steers (p<0.01). Dressing percentage varied from 53.2 % (H) to 54.5% (NH). The highest meat yield (65.9 and 65.6%) were recorded in NH and SH respectively, with the lowest share of separable fat (6.4%) in SH, while the lowest amount of bone (21.5%) in NH crosses (p<0.01). No significative differences were evident for percentage of high commercial value cuts between crosses.
