Abstract

Eight batches comprising 2911 weaner bull calves of the Jamaica Brahman, Jamaica Red Poll, Jamaica Black and composite breeds have completed the 140-day post weaning performance at the Minard facility since 1992. Calves were fed on a group basis, and data on pre-weaning and weaning parameters collated. Final indices and ranking were based on average daily gain, 400-day weight, and weight per day of age. Average daily gain on test over all breed groups by batch were: 1.40; 1.19; 1.15; 1.30;1.24;1.23; and 1.25 Kg respectively, 40o-day weights over all breed groups by batch were: 365.36; 382.14; 388.82; 421.45; 415.41; 392.41; 405.05; and 378.20Kg. Weight per day ofage was 0.73; 0.86; 0.90; 0.93; 0.86; 0.88; 0.96; and 0.83 Kg. Breed and batch differences were observed among the three traits.
