Abstract:
The longevity is an important factor, which affects the total productivity, economy and the rate of genetic gain. There is very little information available in the literature about these traits in Kankrej cattle. As a breed-improvement tool, longevity in dairy cattle can be viewed both from an economic perspective as well as from a breed-improvement standpoint ((34)). This analysis was done on 251 calving records of Kankrej cows collected at Livestock Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat over 15 years i.e. from 2001 to 2015, under identical feeding and managemental circumstances. The mean for longevity of cow was 2568.72±1092.87 days, C.V. being 42.5 percent. The least-square mean for longevity was 2592.56±115.02 days. The Longevity was significantly affected by period of first calving and first lactation milk yield in Kankrej cattle. Non-significant effect of age at first calving and season of first calving were observed on Longevity in Kankerj Cattle.
