Extract

Data on the performance of British, Africander cross British and Brahman cross British females were examined. Of the animals mated only 56-0% of the homebred British cows produced live calves compared with 77-3 and 73-8% from Africander and Brahman cross cows respectively. Evidence was found that the low calving percentage for the.British females was connected with breeding stress, the British females being frequently unable to maintain weight if pregnancies occurred in two successive years. Under similar stress conditions crossbred-Zebu cows could thrive and breed and crossbred Brahmans in particular would normally maintain their weight.
