Effect of eCG and laparoscopic insemination on reproductive performance in F1 (Damara x Merino) ewes
Forty five F1 (Damara x Merino) ewes with 123 +/- 27.6 days post partum were used to evaluate two differents dosage of equine chorionic gonadotropin (eCG) plus laparoscopic insemination (IL) and its effect on oestrus presentation, fertility and prolificacy percentages under conditions of humid tropi...

| Sumario: | Forty five F1 (Damara x Merino) ewes with 123 +/- 27.6 days post partum were used to evaluate two differents dosage of equine chorionic gonadotropin (eCG) plus laparoscopic insemination (IL) and its effect on oestrus presentation, fertility and prolificacy percentages under conditions of humid tropic conditions. To synchronize oestrus ewes were treated with controlled internal drug release (CIDR) devices containing 0.3 g of progesterone for 12 d. Ewes were assigned randomly to three treatments: T1. CIDR plus natural mating |
