L'insémination artificielle intra-utérine, transpéritonéale chez la chèvre: 2. Etude comparative du taux de fécondation après saillie ou insémination artificielle intra-utérine

This study was carried out on 570 ovocytes. It shows that goats suprovulated due to FSH treatements of 16 mg Armour given over 3 days (in 8-4-4 mg/day) or 21 mg Armour over 4 days (in 7-6-4-4 mg/day) and undergoing a single intra-uterine transperitoneal insemination under endoscopic control, carried out 46h39 after removing the sponges gives a satisfactory rate of fecondation close to 70%. This rate is a more 15 points lower than that obtained by 2 successive matings 12 hours apart (36 and 24 hours after removing the sponges). An FSH treatment of 21 mg Armour over a three day period (mg/day:11,5,5) only gives a fecundity rate of 19,5% in intra-uterine and 56.58 % after mating. This gives a global fecundity rate for all treatments of 50.77% and 80.44% for A.I. through intra-uterine method and mating.
