Animal Science 305 Homework 6 Summer 2022 Weaning weigh information for Brahman and Hereford: _ _ B = 530 lbs H = 495 lbs MB= 26 lbs MH = 0 lbs HVdirect = 50 lbs HVmaternal = 30 lbs Calculate the expected average weaning weights for: 1. a. Calves sired by Hereford bulls out of Brahman cows. b. Calves sired by Brahman bulls out of Hereford cows. 2. Calves sired by Brahman bulls out of F1 Brahman-Hereford cows 3. Calves sired by cows Hereford bulls and out of F1 Brahman-Hereford cows. Consider these calves to be the first generation of ¾ Hereford ¼ Brahman composite. 4. a. Calves by ¾ Hereford ¼ Brahman like those from NUMBER 3, and out of cows of the same type as these bulls. These would be considered the second generation ¾ Hereford ¼ Brahman composite. b. Calves ¾ Hereford ¼ Brahman that were produced in NUMBER 4a. and out of cows of the same type as these bulls. This would be the third generation of ¾ Hereford ¼ Brahman composite. Note that calves in later generations of this composite would have the same expected average weaning weights as these third-generation calves. 5. Consider the ¾ Brahman cows ¼ Hereford produced from the cross in number 2. These cows were used to start a two-breed rotation. a. Calculate expected average weaning weights for calves of this rotation. (Note what breed makes up the majority of these cows and what breed is the minority, this will help you pick the correct sire for this generation in the rotation.) b. Calves in the next generation of this rotation. 6. a. Calves in advanced generations (at equilibrium) of a two-breed rotation of Brahman and Hereford, where the calves are sired by Hereford bulls and their dams were sired by Brahman bulls. b. Calves in the next generation of this
