Abstract:
The present investigation recorded that the average litter size was 2.03 per doe and the prolificacy rate being 202.92%. The result indicates that the litter size proportion for single, twin and triplet were 28.3%, 40.4% and 31.3% respectively. There was a tendency of increasing body weight with higher litter size and such variation was highly significant (P<0.01). The result revealed that the overall mean age of first estrus was 209.08±2.06 days. Maximum age of first conception was 226.18±5.39 days when the animal gave single birth and the minimum AC was 216.65±4.9 days when it produced triplet indicating that failure of conception was more in single bearing does. Service period were recorded to very significantly (P<0.01) among different litter bearing groups, the highest value was observed in triplet producing does (80.88±4.68 days). This is an important finding to understand that, less Age of Puberty (AP), Age at 1st Conception (AC), Days Open (DO) & Kidding Interval (KI) has prominent benefit for multiple foetuses and thus achieving economic benefit.
