Abstract:
The present study was conducted to evaluate the effect of non-genetic factors of reproduction performance traits {First service period (SP), First dry period (DP), First calving interval (CI), Number of AI for first Conception (FNI) and Number of AI for second conception (SCI)} in Hardhenu Cattle. The records pertaining to the first lactation of 341 cows, the progeny of 51 sires; calved during the year 1995-2018 and maintained at Cattle Breeding Farm, LUVAS, Hisar were analysed by using a mixed technique of Harvey model. The overall least-squares means of SP, DP, CI, FNI and SCI in Hardhenu cattle for present investigation were 172.57±9.86 days, 135.29±7.07 days, 456.48±9.35 days 2.06±0.13 and 2.87±0.16, respectively in Hardhenu cattle. The effect of calving period on SP, CI and SCI for Hardhenu cattle was obtained significant. The effect of season of calving was significant on all the reproduction performance traits under the present study in Hardhenu cattle except FNI. The results revealed that the effect of the linear regression of age at first calving was significant (p< 0.05) on SP and FNI in Hardhenu cattle.
