  The data collected from 1986 to 2019 at Adea-Berga Jersey herd improvement farm was used to estimate genetic parameters for milk production traits (Lactation Milk Yield (LMY), Daily Milk Yield (DMY) and Lactation Length (LL)). The traits were estimated by using WOMBAT software. Univariate analysis was undertaken for each trait for estimation of parameters (heritability, repeatability, and breeding values) and genetic and phenotypic correlations were estimated with bivariate analysis. The direct heritability estimates for LMY, DMY, and LL of pure Jersey dairy cows were 0.14 ± 0.00, 0.12 ± 0.04, and 0.04 ± 0.02, respectively. The repeatability of LMY, DMY, and LL were 0.33 ± 0.00, 0.40 ± 0.02, and 0.10 ± 0.02, respectively. The genetic correlations between milk productions traits varied from -0.93 ± 0.22 to 0.98 ± 0.07 while the va.. Read More»
