Comparing Some Reproductive Characters Of Awassi Ewes Inserted With Spanish (Ovejero Comp.) and Holland (Intervet Comp.) Made Vaginal Sponges

Awassi sheep herd (105 Ewes) was used to perform this study. Fifty (50) ewes were inserted with Spanish made (SMS) Vaginal sponges (1st group) and twenty four(24) ewes were inserted with Holland made (HMS) Vaginal sponges (2nd group), while thirty one(31) ewes (sponges free) were allowed for a natural mating (NM) System (3rd group). The statistical analysis of the data using the Least square means method indicated that the pregnancy and fertility rates were significantly (p≤ 0.05) higher in (HMS) (0.810 and 0.790) and (NM) (0.801 and 0.694) than that (0.483 and 0.416) of the (SMS). While variations in born lamb rates between the three treatments were not significant . The two sponged groups (SMS) and (HMS) gave significantly (p ≤0.01) better twin rates (0.191 and 0.167) than that (0.048) of the (NM) ewes. Male / female lambs , lamb birth weight , lamb weaning weight , weaning rates (lambs / ewe) were all significantly (p ≤ 0.01) higher for (HMS) and (NM) than (SMS) ewes. Young ewes appeared to be more vigor and prolific than older ewes. One and 2 years old ewes gave higher pregnancy and fertility rates than those in age 3 and 5 years and significantly (p ≤ 0.05) higher than those in age 4 , and significantly higher at (p≤0.01) level in male / female rate . Born lamb rates differences between age groups were not significant. Twin rate produced by age 1 was (zero) significantly (p ≤ 0.01) lower than the others , and it was significantly (p≤0.01) higher in benefit of those in age 3 than the others . Ewes in age 4 and 5 appeared to be significantly (p≤0.01) lower than those in age 1 and 2 in lamb birth weight and weaning rates , but they were significantly (p≤0.01) lower than those in age 1 only in lamb weaning weight.
