The Effects Of Different Gonadotrophin Treatments On The Embryo Generation And Quality Of Embryos In West African Dwarf Goats

Abstract

The effects of Ovine FSH, Porcine FSH (FSH-P) and HMG treatments on embryo generation and embryo quality were studied in West African dwarf goats The results on the number of corpora lutea (CL) on the ovary was (10.12 + 0.06) in FSH-P and (11.35 + 1.75) in FSH-O. However, they differed significantly (P < 0.05) from HMG (8.02 + 2.15) in CL values. The number of embryos recovered in FSH-P (7.25 + 0.04) and FSH-O (7.85 + 0.06) were similar (P > 0.05), but differed significantly (P < 0.05) from HMG (5.15 + 0.03). The ova/embryo wastage was not significantly different (P > 0.05) between T1 FSH-P (14.75 + 0.06%) and T2 FSH-O (13.54 + 0.14%), however, they differed significantly (P < 0.05) from T3 HMG (18.24 + 0.10%). Embryo recovery rate of goats treated with T1 FSH-P (85.02 + 0.06%) however, differed significantly (P < 0.05) from T3 HMG (68.24 + 1.24%). Goats treated with T2 FSH-O recorded higher fertilized embryos of 12.45 + 1.65 which differed significantly (P < 0.05) from T1 FSH-P (7.-0 + 2.15) and T3 HMG (6.16 + 1.12). The number of non-transferable embryos showed no significant difference (P > 0.05) between the treatment groups. The results of this study indicated that FSH-O is the gonadotrophin
of choice for goat superovulation.
