| Abstract |
| The performance traits of Beetal goat (Birth weight, Weaning weight, Yearling weight) from 2006 to 2012 were collected and analyzed to determine the genetic parameters in a purebred flock maintained at Small Ruminant Training & Research center Ravi campus Pattoki-Pakistan. The genetic parameters i.e., heritability, and phenotypic and genetic correlations among various traits were estimated. The breeding values for different traits were estimated for comparative ranking of animals. Phenotypic and genetic trend lines were drawn to assess the selection success in previous generations of Beetal goat. All these analyses were carried out using WOMBAT Computer software. The birth and weaning weight of Beetal goat averaged 2.83 ± 0.11 kg and 10.25± 0.71 kg whereas yearling weight was 19.72 ± 0.72 kg. Birth weight of Beetal goat varied significantly due to year, season, sex and type of birth. Analysis of variance showed significant effect of birth weight, weaning age and season of birth on weaning weight of Beetal goat whereas year of birth, type of birth, sex and kidding number showed non-significant effect. The estimates of heritability for birth weight, weaning weight, yearling weight in Beetal goat were similar i.e. 0.126 while post weaning average daily weight gain (3-6), (6-9),(3-12) estimated heritability were 0.127, 0.127, 0.118. The low heritability indicated the presence of less additive gene variance and large environmental variance. Hence, improvement in the traits through selection may be limited. |
