Abstract

90 of Awassi ewes (2-7) years old, (44,18) Kg weight  and in a good health, were used to study the, efficieny of hormonal treatment, by using intravaginal progestagen sponges containing 60 mg of medroxy progesterone acetate (MAP) followed by treatment with equine chorionic gonadotrphin (eCG), birth on weight and weight at weaning. 90 of Awassi ewes were randomly chosen at one of the breeders. That ewes have been weighed and fixed their ages, intravaginally sponges with 60 mg medroxy progesterone acetate, and after 14 days all the ewes were injected intramuscularly with 500IU eCG of ,and the treatment has been repeated for three times in 8 months interval to get three births during two years. It was found, that average weights of the total males at the birth were 4,59±1,28kg,4,63±1,34kg,4,95±1,22kg in the first, second and third experiment respectively. The aveage weights of total females at the birth were 4,34±1,05kg, 4,72±1,16kg, 4,59±0,92kg in the first, second and third experiment respectively, and the aveage weight of males at the weaning 14,85±4,87kg, 18,30±3,39kg, 18,83±2,83kg, in the first, second and third experiment respectively, the aveage  weight of females at the weaning 14,52±4,36kg, 18,22±2,58kg, 17,96±2,27kg, in the first, second and third experiment respectively. It was concluded that the hormonal treatment could be used for intensification of the sheep production and for increasing the reproductivity of Awassi sheep. The usage of hormonal eCG had clear affecting on increasing the number of born lamb, without effection on the average birth and weaning weight of the lambs.
