Forty-four young bulls of herds selected for weight at 378 days of age (W378), born in 1995, were confined at the Sertãozinho Experimental Station, São Paulo State, Brazil. The samples, representing the W378 overall mean for each herd, were formed by 8 Guzera bulls (GuS) and by 9 bulls of each one of the groups Gir (Gi), Nelore (NeS), Nelore Control (NeC) and Caracu (Ca). The slaughter was carried out when the animals were at 580 days of age, with […]

The objective of this experiment was to evaluate the carcass and meat characteristics of Hereford (H), 5/8 H 3/8 Nellore (N), 1/2 H 1/2 N and 1/4 H 3/4 N steers, feedlot finished, from 20 to 24 months of age. Twenty-four steers randomly taken from the same herd were used. The diet contained, in a dry matter basis, 12.7% of crude protein and 57.5:42.5% forage:concentrate ratio. The forage was composed by corn silage + sugar cane (relation 1:1). The slaughter […]
