An increased number of anestric goats was noticed in the production herd of goats under the influence of deteriorating climatic conditions towards the end of the mating season (November 1993). The animals were sonographically examined for pregnancy with the SSD-210 DXII apparatus. Three experimental groups A, B, C with 15 animals in each were created according to the scheme of hormonal treatment, and one control group D (n=7) without treatment was created, to synchronize the sexual cycle. The goats were of Saanen and Alpine breeds and two years old. The combination of EAZI-breed CIDR G preparations (CARTER HOLT HARVEY PLASTIC PRODUCTS, 696 Te Rapa Road, Hamilton, New Zealand, 9 % Progesteron 0.3 g) were used in group A. The preparation was inserted into the vagina for 18 days, and on the day the insertions were removed 500 i.u. PMSC were applied intramuscularly (Serum gonadotropin, Bioveta Ivanovice na Hane, CR). Group B was inserted with the vaginal insertions Chronogest (Intervet-Holland, 40 mg - cronolone) for 18 days. On the day the insertions were removed the animals were applied 500 i.u. Chronogest PMSC i.m. (Intervet-Holland). Vaginal insertions EAZI breed CIDR G were used in group C for 18 days. FSH (Follicotropin a.u. vet., Leciva Praha, CR) was applied on the 18th day. Hand mating with billy goat was done 24-72 hours after the insertions were removed. Oestrus was noticed in 58 % animals out of the total number of 45 goats. There were 46.6 % in group A, 33.3 % in B, 93.3 % in C, 14.3 % in D. Pregnancy was determined sonographically on the 40th-50th day after mating and represented 13.3 % out of the total number in group A, 13.3 % in group B, 46.6 % in group C, and 0 % in group D. The best results were achieved in group C. This scheme is recomended for practice.
