Genetic persistency of first lactation milk yield estimated using random regression model for Indian Murrah buffaloes



Genetic persistency of first lactation milk yield estimated using random regression model for Indian Murrah buffaloes



Asian Australasian Journal of Animal Sciences 19(12): 1696-1701



A random regression model was applied for the first time for the analysis of test day records and to study the genetic persistency of first lactation milk yield of Indian Murrah buffaloes. Wilmink's Function was chosen to describe the shape of lactation curves. Heritabilities of test day milk yield varied from 0.33 to 0.58 in different test days. The highest heritability was found in the initial test day (5(th) day),milk yield.
