Description
Summary:Records belonging to 1248 Teddy goats kept at the Livestock Production Research Institute, Bahadurnagar, (Okara), Pakistan were analyzed to identify genetic and environmental factors affecting pre-weaning average daily weight gain. Sex of kid, season and year of kidding affected average daily weight gain significantly (P<0.01). Male kids gained at a faster rate (111.00 ± 6.01 g/day) than female kids (106.00 ± 6.06 g per day). The kids born in summer gained 108.90 + 1.3 g per day, which. was lower (P<0.01 ) than winter born kids ( 115.4 ± 1.4 9 per day). Different years of birth had shown gradual decrease in pre-weaning average daily gains. The effects of. parity of dam and birth type were found to be non-significant. Habitability estimate for daily weight gain was 0.12 ± 0.06. The phenotypic and genetic trends were negative.
