چکیده مقاله:
The selection of milch buffaloes at an early age on the basis of part yields is beneficial to the dairy farmer as it cuts down the cost of rearing the animals and also helps in progeny testing. Part yields (monthly milk yield)or cumulative monthly records have been shown to have a very high genetic and phenotypic relationship with full records. The ability to predict the complete lactation period of a buffalo from its part yields would determine the successes of dairy herd culling programs. In dairy buffalo, a high rate of genetic improvement is only possible through the early culling of low-producing buffaloes. This can be achieved by selecting females and bulls on the basis of their part records provided that full lactation yield can be accurately predicted from part yields. Predicting total lactation yield on the basis of part lactation records has practical utility. The present study was undertaken to find out the earliest part lactation yield of the first lactation which can efficiently predict the complete lactation yield.DOR: https://dorl.net/dor/۲۰.۱۰۰۱.۱.۲۳۴۵۴۳۷۷.۲۰۲۲.۱۰.۱.۱.۹The selection of milch buffaloes at an early age on the basis of part yields is beneficial to the dairy farmer as it cuts down the cost of rearing the animals and also helps in progeny testing.
