| Abstract | ||
| The study was conducted to estimate the reproductive performance in 101 yearling Goats represented Two Breeding Group (35Native Black does and 66 Imported Damasks does) joined in reproductive season (2007). Fertility (does lambed per does joined), Twinning percentage (twinning lambing per does lambed), Lambing percentage (kids porn per does lambed), mortality (kids died per kids born), Prolificacy (kids weaned per does joined) and weaning percentage (kids weaned per does lambed) were tested. No significant deference’s between Imported and native breed in fertility (33.3 compared with 37.1%), prolificacy (37.8 compared 40.0%) Lambing percentage (113.6 compared with 107.6%), and weaning percentage (104.5 compared with 92.3%). Imported yearling does superior native does significantly (p<0.05) in twinning percentage (15.0 compared with 7.6%) and kids mortality (8.0% compared with 14.2. Results showed that the adults and yearling does had similar performance in mortality and daily weight gain. Yearling group had less performance compared with adults group in fertility, twinning percentage, prolificacy and weaning percentage. It was concluded that yearling does in both breeds showed a good ability to rear their kids at weaning. | ||
