Comparative performance of calves from Bunaji (White Fulani) dams and Gharolais, three-quarter Friesian and Bunaji sires

Abstract

SUMMARYComparative evaluation was made on the live weight and growth pattern of calves from Bunaji (White Fulani) cows sired by Charolais, three-quarters Friesian crossbreds (three quarters Friesian and one quarter Bunaji) and Bunaji bulls in 2 years. Twelve steers per breed were evaluated on carcass merit after 250 days postweaning feeding.Results showed that the Charolais half-cross and the Friesian three-eighth calves were heavier by up to 7, 23, 57 and 51 kg respectively at birth, weaning, 112 and 250 days after weaning than the Bunaji calves. The carcass data indicated superior slaughter weight and loin eye area in favour of the cross - breds, but no differences were found for dressed weight, dressing percentage, carcass grade and hide weight percentage among the breed groups. Carcass retail cuts showed heavier sirloin steaks and round steaks in favour of the cross-breds also.The results were indicative of the superior growth of the cross-breds and underlined their carcass potential which may be useful in upgrading the indigenous stock. In view of the small numbers of progeny per sire group, especially among the cross-breds, further work needs to be done to confirm the present trend.
