Abstract:
At an organised farm, the present study explored the effect of first lactation milk yield on productive herd life, longevity, and lifetime calf production in Kankrej cattle. The data on history sheets of Kankrej cattle spread over a period of 15 years (2001-2015) were collected from Livestock Research Station, Sardarkrushinagar, Dantiwada Agricultural University, Sardarkrushinagar, Gujarat situated in semi-arid region of Banaskantha District of North Gujarat region having latitude of 24.35º North and longitude of 72.59º East. 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. Significant effect of first lactation milk yield was observed on 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.
