Calving pattern and herd fertility in crossbred and Holstein-Friesian cows

Calving pattern and herd fertility in crossbred and Holstein-Friesian cows

Indian Journal of Animal Production and Management 4(1): 5-8

Data on 2- and 3-breed crosses of Haryana with Brown Swiss, Friesian and Jersey cattle and on Holstein-Friesians (HFs) calving in 1973-86 were analysed. For 2-way crosses, calving percentage was highest in Nov.-Jan. and lowest in May-July. It decreased from Feb. to June for 3-way crosses and from Feb. to July for HFs.
