Abstract:
Kankrej cattle at an organised farm were studied to determine the effect of age at first calving on productive herd life, longevity, and lifetime calf production. This study examined the history sheets of Kankrej cattle spread over a period of 15 years (2001-2015) at Livestock Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, located in semi-arid Banaskantha District of North Gujarat region with longitude 72.59º East and latitude 24.35º North. The least-square mean for productive herd life (days), longevity (days), number of calves born to each cow, number of female calves born to each cow and number of female calves reaching milking herd from each cow were 1351.99±114.55, 2592.56±115.02, 3.21±0.25, 1.56±0.17 and 1.09±0.14, respectively. It was observed that age at first calving had no significant effect on the productive herd life, longevity, number of calves born per cow, number of female calves born per cow, number of female calves reaching milking herd per cow.
