Effect of Repeated Super-ov Treatment on Superovulatory Response and Embryo Recovery Rate in West African Dwarf Goats

摘要

A total of 18 parous, healthy and cyclically sound 2-3 years old West African dwarf goats were used to study the effect of repeated super-ov treatment on superovulation and embryo recovery rate. The goats were divided into 3 treatment groups identified as T1, T2 and T3 consisting of 6 goats in each group. T1, the control was administered with physiological saline, T2 administered with super-ov regarded as Initial treatment and T3 regarded as repeated administration of super-ov. The results show that the superovulatory response (CL) during initial and repeated stimulation averaged 7.57±0.52 and 6.85±0.48, respectively. The higher embryo recovery 78.00±0.08% in repeated group differed significantly (p<0.05) from initial super-ov treatment 45.00±0.06% and the control group 30.00± 0.02%. The lower number of embryos and transferable embryos of 4.00±0.60 and 3.75±0.85, respectively in the initial super-ov treatment than to second stimulation 5.00±0.84 and 4.85±0.94 were due to ovarian hyper stimulation in these animals. The results indicated that super-ov treatments induce superovulatory response in West African dwarf goats.
