A total of 2592 calves produced in Nebraska and Florida were used to evaluate the importance of genotype by location interactions on reproductive and maternal performance of eight breeds groups of dam. Breed groups of dam included Angus-Hereford reciprocal crossbreds, Pinzgauer-Angus, Pinzgauer-Hereford, Brahman-Angus, Brahman-Hereford. Birth and weaning weights and preweaning average daily gain were highly influenced by the genotype-location interaction. The significant breed group of dam by location interaction observed for birth weight was the result of a reversal in rank of Brahman-Hereford and Brahman-Angus cows at the two locations. Calves from Brahman-Hereford dams in Florida were heavier at birth than those from Brahman-Angus, whereas in Nebraska, thereverse was true. The taurus-taurus F1 cows (Angus-Hereford reciprocal crosses and Pinzgauer crosses) weaned heavier calves at the Nebraska location than they did at the Florida location, whereas the weight of calves weaned by the zebu-taurus F1 cows (Brahman-taurus and Sahiwal-taurus crosses) was not influenced by location. There was a change in the rank of Pinzgauer-taurus and Sahiwal-taurus at the two locations for preweaning calf average daily gain. Calves by Pinzgauer-taurus dams gained more weight from birth to weaning than did those from the Sahiwal-taurus dams the comparison was made at the Nebraska location. Calves by the Sahiwal-taurus dams were superior at the Florida location. Interactions of age of dam and breed group of dam were important...
