Abstract
During the routine Veterinary clinical examinations around Tripoli, 275 cows were suffering from different reproductive disorders. Between these cows, 63 cases (23.6%) were diagnosed as true anoestrus with inactive ovary. Dalmarelin was injected to each cow in a dose of 0.2 ml (50 mcg) intramuscular. Fifty four cows (85.7 %) showed positive by showing estrous signs, response within first week. Twenty four of them were inseminated and showed pregnancy in 22 cases (91.66 %). From the rest 30 cows, 26 of them received Dalmazin in a dose of 0.3 ml (0.225 mg) intramuscular and inseminated on day of estrous. Pregnancy was diagnosed in 25 cases (96.15 %). The 16 non respond cows were reinjected by Dalmarelin and inseminated on day of estrous. Thirteen cows were positive for pregnancy diagnosis. It could be concluded that the use of Dalmarelin and, or Dalmazin at late postpartum stages parallel with balanced nutrition will help a lot in reducing ovarian dysfunctions.
