Oestrus behaviour and conception rates of red sokoto goats following treatment with equine chorionic Gonadotrophin and Prostaglandin

This study was designed to investigate whether the administration of equine chorionic gonadotrophin (EG) concurrent with prostaglandin (PG) treatment improved oestrus response rates of Red Sokoto does. Red Sokoto (RS) does were treated with PGF2α (RSPG; n=10), PGF2α and eCG (RSPGEG; n=10) and eCG (RSEG; n=10). Heat detection and natural mating was carried out using sexually active fertile bucks following treatment for 5 days. Oestrus response rate was higher (p<0.05) in the RSPGEG than in the RSPG and RSEG groups respectively. Time to onset of oestrus was shorter (p>0.05) while duration of oestrus was longer (p>0.05) in the RSPGEG than in the RSPG and RSEG groups. Conception rates were 77 %, 80 % and 0 % in the RSPGEG, RSPG and RSEG groups respectively. We concluded that administration of equine chorionic gonadotropin concurrent with prostaglandin treatment improved oestrus response rates in Red Sokoto does.Keywords: Red Sokoto Goat, Prostaglandin, Gonadotrophin, Oestrus Response, Conceptio
