Age at first calving and lifetime performance of Hariana cattle at organized farms

Abstract

The present investigation was undertaken to access age at first calving, actual lifetime milk yield per day of productive life, actual lifetime milk yield per day of herd life and actual lifetime milk yield per day of total life. The non-genetic factors such as period of birth, season of birth, AFC age group and farms on these traits were studied by least-squares analysis and the means were compared using Duncan's multiple range test. The least-squares means for age at first calving, actual lifetime milk yield per day of productive life, actual lifetime milk yield per day of herd life and actual lifetime milk yield per day of total life were estimated as 1668.3±16.6 days, 1.878±0.04 litres/day, 1.735±0.05 litres/day and 1.029±0.03 litres/day respectively. Farm and period of birth had significant effect on age at first calving, actual lifetime milk yield per day of herd life and actual lifetime milk yield per day of total life. In actual life time milk yield per day of productive life, period of birth had significant effect. AFC class had significant effect on actual lifetime milk yield per day of total life.

Genetic study of important economic traits in Hariana cattle

“…India is the largest producer of milk in the world with the highest cattle population. These cattle are playing an important role in strengthening India's economy (Shetkar et al 2021a). Animal husbandry sector of India has a cattle population of 193.46 million in total among which indigenous cattle population is 142.11 million (20 th Livestock Census 2019) which adds up to 73.46% of total cattle population of India with 53 recognized breeds of cattle (ICAR-NBAGR 2022) spread across the country and providing livelihood sustenance to millions of rural livestock keepers.…”
