A study on breeding and calf rearing management practices of Varanasi district in Uttar Pradesh was carried on by collecting data from 250 dairy farmers of 5 different block viz. Sewapuri, Kashi Vidyapeeth, Arajiline, Rohaniya and Chiriagoan of Varanasi district. The study revealed that almost all the respondents relayed only on symptoms of estrus and particularly mucus discharge alone (33.6%) or in combination of other symptoms of estrus like bellowing (45.2%) and restlessness (21.2%) for heat detection in their animals. Respondents were breeding their animals by AI (26.8%), natural service (26.8%) and by both (46.4%). Mostly (73.2%) respondents mate their animals after 18 hrs of heat detection, while maximum (41.6%) number of respondents bred their animals between 3-5 months after calving. In case of calf rearing management practices, study revealed that 70% of respondents attended their animals during calving, while only 30.4% of respondents practiced ligation, cutting and disinfection of navel cord. Only 32% respondents fed their calves colostrum within 2 hrs of birth. 66.4% of respondents weaned their calves at 3 months of age, rest never weaned their calves. Majority 57.6% of farmers provided calf starter to their calves, while 42.4% didn’t provided calf starter and 68.4% of respondents fed fodder to their calves around 2 months of age. Only 38% respondents were dehorning their calves and 33.2% castrating their male calves in the study area.

The present study was undertaken on data of 113 Gir cows maintained at Kasturba Gram Dairy Farm, Indore, Madhya Pradesh, India over a period of 18 years from 1995 to 2012, based on age at first calving. The overall means for weight at first calving (WFC), age at first calving (AFC), and first lactation milk yield (FLMY) were 402.22± 1.28 kg, 1709.04± 51.92 days and 1664.95± 280.72 litres respectively. The heritability estimates for WFC, AFC and FLMY were 0.248± 0.234, 0.307± 0.206 and 0.112± 0.252 respectively. The genetic correlation between WFC and AFC was positive and significant, while it was negative in between WFC and FLMY. The genetic correlation between AFC and FLMY was low and negative. The phenotypic correlations between all traits were positive.
