Contents:This report presents results of several experiments done with Angora, Alpine and Saanen goats in order to define the actual feasibility of production, storage and transfer of embryos in this species. The superovulatory regimen used pFSH administered a t the end of a progestagen treatment (45 mg FGA vaginal sponges, 11 days). When 16 mg Armour equivalent are administered t o dairy goats the numbers of CL and of transferable embryos are significantly higher (P < 0.05) if the FSHILH ratio decreases from first to last injection (8-1 -0.4) compared to constant FSHILH ratio ( I ) , (CL: 13.0 us 6.8, transferable embryos: 4.9 us 1.6). During commercial activity the production of transferable embryos was found to be lower (after 16 mgpFSH and surgical recovery) in Angora compared t o Aipine goats (5.2 vs 6.7) and (after 20 mgpFSH and laparoscopic recovery) in Angora goats treated during 3 days compared to 4 days (4.2 us 5.7). The level of stimulation induced by 16 mg pFSH with decreasing FSHILH ratio in dairy goats does not differ significantly between breeding and out of breeding season (CL: 13.7 us 11.9, transferable embryos: 4.7 us 4.0). Repeating this treatment every 7 weeks decreases the response (1st treatment: 12.8 CL, 4.3 transferable embryos; 2nd t o 5 t h treatment: 8.6 CL, 1.9 transferable embryos, P < 0.05). After 19.9% of the treatments large unovulated follicles were observed on the ovaries a t the time of embryo recovery and for 10% some or all of the CL were regressing (Corpora albicans). Oestrus was observed 24 to 5 4 h after sponge removal and this interval affected ovulation rates (24 h: 14.4 CL; 3 0 h: 9.6 CL; 4 8 h 8.6 CL; P < 0.01). 71 and 60.2% of the eggs are fertilized after hand mating or A I respectively. Timing of A I and number of CL influenced the fertilization rate (65.2% f o r A I at the beginning of oestrus us 52.1 % for A I at the end of oestrus, P < 0.05; 66.1% f o r < 15 CL us 48.8% f o r > 15 CL, P < 0.01). The use of laparoscopy has been developed f o r embryo recovery and transfer. The recovery rate is lower (62 us 85%) but each donor can be collected more than 7 times without severe adhesions. After transfer pregnancy rate is higher after surgery (74.4% us 42.5% P < 0.01).
