Number of coitus, luteinizing hormone and reproductive performance relationships in doe rabbits

The study was carried out on 50 does of Bauscat rabbits in three groups. Luteinizing hormone (LH) reached peak level at 90 minutes after the first coitus in group 1 (having one coitus only), group 2 (having two coitus one hour apart) as well as group 3 (having two coitus two hours apart). However, LH peak level returned at 90 minutes after the second coitus in group 2 only. Therefore, the ovulation rate (O.R.) was significantly higher in group 2 than in other groups. The highest conception rate was found in group 2, then followed groups 3 and 1 respectively. The mean litter size and litter weight were significantly higher in group 2 than other groups.
