Estimation of Heritability of Karan Fries Cattle using Bayesian Procedure
Indian Journal of Animal Sciences, 2022   The Bayesian model was applied for analyzing the first lactation in Karan Fries cattle. First lactation data of production (305-day or less milk yield and daily milk yield) were collected from the history-cum pedigree sheet and daily milk yield ...
