A note on reproduction efficiency of an inter-bred taurus-indicus herd

A note on reproduction efficiency of an inter-bred taurus-indicus herd

Indian Journal of Dairy Science 42(3): 614-615

For 243 crossbred Holstein X Jersey X Tharparkar cows having 50-87.5% Bos taurus inheritance and mated to Karan-Friesian sires, the number of services per conception averaged 2.18+or-0.10, interval from calving to 1st post partum oestrus 85.5+or-7.3 days, and service period 138.6+or-8.3 days. The number of services per conception for animals with <50 and >50% of exotic blood averaged 2.22 and 2.12 resp.
