Abstract

Present research was carried out to investigate the genetic characteristics of Pak-Awassi Sheep with respect to the growth performance traits and estimation of the genetic parameters. The 10 years (2004-2013) data regarding the growth performance traits of Pak-Awassi sheep maintained at livestock experimental station Nabisr, Umar Kot, Sindh were utilized for the current study. The result for genetic parameters heritability for birth weight and yearling weight was observed low, while correlation and regression coefficient was observed medium and positive for birth weight and yearling weight. The effect of season was observed significantly higher on lambing rate of Pak-Awasi sheep. It is concluded that winter season has significant effect on lambing rate, while the low heritable traits can be improved with better management and selection practices.
