Description

Byline: Muhammad Akhtur Qureshi, Masroor Ellahi Babar and Ahmad Ali* Abstract.- This study was conducted to estimate the genetic and environmental components of variation influencing various trails of economic importance in Kajli sheep. Data on 16,470 birth records from 5311 Kajli ewes kept at different livestock farms in Punjab province during 1977-1994 were utilized in the study. Mixed Model Least Square and Maximum Likelihood algorithms were applied to analyze the data using Harvey's statistical software. Birth, weaning and yearling weights in Kajli lambs averaged 3.7+-0.01, 20.8+-0.09 and 37.2+-0.38 kg, respectively. The body weight averages were significantly (pandlt;0.01) influenced by location, year and season, birth type environmental factors studied. Pre weaning and post weaning daily gains averaged 140.9+-0.80 and 68.5+-1.5 g, respectively.
