| Abstract: | Ten crossbred cattle of Nanyang cattle with Chairolais, three with 50 percent of Nanyang cattle blood, four with 37.5 percent of Nanyang cattle blood and two with 35 percent of Nanyang cattle blood were slaughtered and their beef performance were measured. The slaughtering results showed that average slaughter rate, net beef rate, beef percentage of carcass, rib eye area, ripen beef rate, shear force, bone and beef ratio, selected and choice beef rate were 60.13%, 48.84%, 82.63%, 117.7 cm2, 58.66%, 2.61, 4.81:1, 38.37%, 14.35%, respectively. Compared with Nanyang cattle without finishing period, the slaughter rate, net beef rate of the crossbred individual were increased by 7.93% and 5.24% than that of Nanyang cattle. |
