Abstract

Bulls from three water buffalo genotypes, Philippine Carabao, Bulgarian Murrah buffalo, and US Murrah buffalo were evaluated from 2002 to 2012 in order to estimate the genetic parameters for growth traits. A total of 1075 observations for birth weight, yearling weight, 2 year old weight and 3 year old weight were analyzed for variance and covariance components using Multi Trait Derivative Free Restricted Maximum Likelihood (MTDFREML) by Boldman et al., 1993. For the three genotypes all the growth traits studied showed medium heritability estimate ranged from 0.40 to 0.50. Genetic correlations among traits were all medium and positive which suggest that birth weight could be used as an indicator for early selection for growth considering its positive genetic correlations with succeeding growth traits like yearling weight, 2 year old weight and 3 year old weight.
