Abstract

This trial was conducted on (10) Awassi ewes in (2 ــ 3) years old , animals were dividing randomely into two groups .This first group injected with prosolvin drug at dose f (7.5) mg while the second set with (125) mg Estrumate I.M Sign of oestrus was dedected on the second day of injection for over five past day . Reinjection of two groups with same dose of the drugs on the ninth day of the first dose injection . The ewes were mated if any oestrus sign appear by using a ram with (3) years old . The results showed that the treatment in one of prostaglandin analogue know as prosolvin ( Luprostiol) have failed in the process of oestrus synchronization in ewes compared with the second Estrumate drug (Cloprostenol) which led to the oestrus Synchronization in ewes by 60 % .The results of the analysis of the progesterone after drug treatment for prosolvin rates were concentration of the hormones in the blood of animals prior to their first dose injection was ( 0.318 + 0.057 ) ng / mL And before injection of the second dose was (0.238 + 0,262 ) ng / mL . where were progesterone rates during treatment were to low . As the results of progesterone analysis during drug therapy (Cloprostenol) was the average of hormone concentration in the blood of ewes before the first dose injection ( 1.28 + 0.630 ) ng / mL . and before injection of the second dose was ( 1.57 + 0.580 ) ng / mL .
