Abstract:
The objective of the present study was to determine the effect of period of first calving on productive herd life, longevity, and lifetime calf production in Kankrej cattle on organized farms. 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. The productive herd life, longevity, number of calves born per cow, number of female calves born per cow, and number of female calves reaching milking herd per cow were significantly affected by period of first calving.
