| Description |
The analysis of effect of age at first calving on different lifetime production traits in all the four categories of Jersey cattle revealed that though the majority (60.6 per cent) of the imported Jersey cattle were calving at ≤750 days, the optimum age at first calving group in hot and humid climatic conditions of Tamil Nadu for higher longevity, productive herd life and lifetime milk production was > 750 to 800 days. However, in farmbred Australian and Danish Jersey cattle, the heifers freshening at ≤ 750 days and ≤ 1000 days respectively resulted in higher longevity, productive herd life and lifetime milk production. It may be concluded on the basis of finding that the age at first calving should be given due weightage for improving the lifetime production traits of Jersey cattle.
