Estimation of Genetic Parameters for Weights at Different Ages in Anatolian Buffalo Calves

Background: The determination of the breeding potential and direction population in terms traits interest depends on genetic variation. Therefore, it is essential to know parameters economic improve yields animal breeding. objective this study was investigate heritability, phenotypic correlations among growth Anatolian buffaloes ìstanbul province. Methods: A total records 7649 birth weights, 4623 sixth-month weights 3133 yearling belonging buffalo calves born between 2012 2021 were used. Genetic estimated from univariate bivariate model using restricted maximum likelihood (REML) procedure Wombat software. Village, year, season, sex age dam considered as fixed effects additive effect taken random effect. Result: heritability estimates for birth, 0.14±0.03; 0.22±0.05; 0.39±0.07 respectively. generally significant positive ranged 0.28±0.02 0.97±0.02. As a consequence, moderate high showed that there some opportunities improvement ìstanbul. These should be selection programs.
