The reproductive performance mothering ability and productivity of cross bred and tswana beef cows in botswana

The reproductive performance mothering ability and productivity of cross bred and tswana beef cows in botswana

Animal Production 35(3): 421-426

ISSN/ISBN: 0003-3561

The calving rates, survival and growth of calves of Brahman (344), Bonsmara (454), Simmental (601) and Tuli (276) crossbred cows, and pure Tswana (405), were collected for a 7-yr period, 1974-1980. Calving and survival rates for calves were 0.90, 0.88, 0.87, 0.87 and 0.82; and 0.94, 0.93, 0.96, 0.94 and 0.93, for Simmental, Tuli, Brahman and Bonsmara crossbreds and pure tswana, respectively. These differences were not significant (P < 0.05). Calves produced by Simmental .male. and Bonsmara .male. crossbred cows were significantly heavier than those from Brahman .male. and Tuli .male. crossbred cows (P < 0.01), but not from Tswana-sired calves. At weaning, calves from Simmental-cross cows weighed 214 kg, significantly heavier than those produced by any other cow type (P < 0.01). Bonsmara- and Brahman-cross cows produced claves weighing 203 and 198 kg, respectively, at weaning, which were also significantly heavier than the calves of Tswana and Tuli crossbred cows (P < 0.01), which weighed 187 and 184 kg, respectively. Productivity estimates combining these 3 traits, and expressed as weight of calf weaned per cow per year, per kilogram cow weight and per kilogram metabolic weight of cow, demonstrate the advantages of 3 of the crossbred cow types over the pure Tswana. Recommendations for the further development of crossbreeding systems in Botswana are made on the basis of this finding.
