| Abstract | ||
| Twenty eight anoestrus Barren mares were classified according to their ovarian size into two groups. Group (A) 18 mares had small inactive ovaries and the mares were injected by 1 mg GnRH 3 times at 10 days intervals. Fifteen mares showed oestrus within 3 - 12 days after me end of treatment. These mares were mated by fertile stallion and the conception rate at induced oestrus was 60%. : Group (B), 10 anoestrus Barren mares, had big ovaries. The mares were treated by 5 mg PGF2 & single injection, mares responded to treatment and showed oestrus within 1-4 days. The conception rate at the induced oestrus was 42.8%. | ||
