AbstractThis study was conducted at Animal Resourse Department College of Agriculture and Forestry at Mosul University for a period from 9/6/2009 to 6/10/2009, to study the effect of vit. A , Folic acid and the Co- effect for both of them on some physiological and reproductive traits for local Awassi ewe lambs 36 ewe lambs 4 month old were used in this study randomly divided into 4 treatments with average weights 22.22 , 22.88 , 23.27 and 22.00 kg respectively.
The first treatment fed on the control ration , the second drunk with vit A 5000 I.U head twice a week , the third drunk with folic acid 25 mg head twice a week , and the fourth treatment was drunk with vit A 5000 I.U with 25 mg head twice a week all the experiment period . The result revealed significant difference (P< 0.05) between the treatments in the average daily and total gain for the behalf of the control treatment , and there were no significant difference in final weight between the treatments , but there was a progress on improvement in fertility percentage for the third treatment reached 66.66% at 8th month of ewe lambs age. At 10th month of age the third and forth treatment were highly significantly superior (P>0.01)then the first and second treatment and reached 77.77% . There was no significant difference in F.S.H hormone level at 7 , 9 , 10 month of age. There was significant difference(P> 0.05) for the 3rd treatment at 7 months of age , the level of F.S.H reached 0.3170 nonogram ml with comparison with 1st and 2nd treatments . Also there were significant differences(P>0.05) in L.H hormone level between the treatments within the 7th month for the behalf of 3rd treatment and 8th month for the behalf of 2nd and 3rd treatments.
