Abstract | | | | The objective of the present study was to evaluate the effect of a progestagen treatment alone or in combination with equine chorionic gonadotrophin (eCG) on estrus response in Sahel (SH) goats. One hundred (n=100) SH does were treated with 30 mg fluorogestone acetate (FGA) sponge for 14 days. At the end progestagen treatment, does that retained the intravaginal pessary were allocated into two groups; A: FGA & eCG (n=42) and B: FGA (n=41). Does in group A received additional 200 IU eCG i.m. concurrent with sponge removal. Estrus was detected twice daily (at 07.00 – 10.00 and 15.00 – 18.00 h) using sexually active bucks for 5 days after pessary removal. Estrus response was different (p
