Abstract:
The data of 250 Phule Triveni crossbred cattle born from 62 sires maintained at Research Cum Development Project (RCDP) on cattle, MPKV, Rahuri for a period of 33 years (1987 to 2020) were collected for present investigation. The overall least-squares means of age at first calving (AFC), first service period (FSP) and first calving interval (FCI) in Phule Triveni crossbred cattle were estimated as 1023.25±10.14, 198.38±9.83 and 477.52±09.82 days, respectively. The period of birth had significant effect on AFC (p<0.01) while the period of calving had significant effect on FSP (p<0.05) and FCI (p<0.05) in Phule Triveni crossbred cattle. The variations due to season of birth in AFC while the variations due to season of calving in FSP and FCI were non-significant in Phule Triveni crossbred cattle under study. There was non-significant effect of peak milk yield on FSP and FCI. The sire had significant effect (p<0.01) on AFC while non-significant effect on FSP and FCI in Phule Triveni crossbred cattle.
