Abstract:
Animal husbandry is dependent on each other, mainly because of small holding of land by majority of the farmer. Unlike the agricultural Western countries, Indian Agriculture depends almost entirely on cattle to meet its draught requirement. The present study was conducted on Genetic studies on calving interval and its influence on some important economic traits in crossbred cattle The data for study were collected from history sheet records maintained at the Department of Animal husbandry and Dairying, Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj, (211007) Uttar Pradesh. Shorter dry period was also observed in calving interval period of 360-450 days among the different crossbred Cows 1/8 jersey X 7/8 Red Sindhi, 1/4 jersey X 3/4 Red Sindhi. The calving intervals the dry period of 1/8 Jersey × 7/8 Red Sindhi crossbred cattle ranged from 26 to 72.Days. The differences in the dry period of 1/8 Jersey × 7/8 Red Sindhi crossbred cattle between calving intervals groups were Non-significant. The butter fat yield of 1/8 Jersey × 7/8 Red Sindhi cross bred cows range from 60 to 142.27 kg. The differences in the butter fat yield (BFY) of 1/8 Jersey × 7/8 Red Sindhi crossbred cows due to different calving intervals were non-significant. Among these Cross bred animals. 1/4 Jersey X 3/4 Red Sindhi has highest 305 Lactation milk yield, Shorter dry period, highest Butter fat yield Irrespective of calving intervals the dry period of 1/4 Jersey × 3/4 Red Sindhi crossbred cattle ranged from 21.0 to 200.0. Days. The differences in the dry period of 1/4 Jersey × 3/4 Red Sindhi crossbred cattle between calving intervals groups were Non-significant. The butter fat yield of 1/4 Jersey × 3/4 Red Sindhi cross bred cows range from 57.00 to 152.2 kg. The differences in the butter fat yield (BFY) of 1/4 Jersey × 3/4 Red Sindhi crossbred cows due to different calving intervals were non-significant. The mean dry period of 1/4 Jersey × 3/4 Red Sindhi crossbred cattle pertaining to 360 days, 390 days, 420 days, 450 days and above 450 days was 39.7, 55.2, 78.3, 64.0, 90.3 days respective.
