This study was conducted on 32 of local Awassi ewes, average body weight 36.06±0.74 kg (aged 2-3 years, ewes were divided into two treatments. The first treatment (T1) the control contained 8 ewes fed on ration consist of barley, wheat bran, urea and wheat straw without supplement and the second (T2) was contained 24 ewes and fed on the same ration of control supplemented with protected amino acids (methionine 2.5 g and lysine 2.5 g) per ewe daily, the ewes were fed with restricted quantity 1 kg / ewe divided twice daily through the flushing and mating period which lasted 60 days, also all ewes was grazed for 6hr daily. Results was referred that protected amino acid supplement in T2 led to a significant (p<0.01) improvement in conception percentage 91.6%, prolificacy percentage 87.5% and lambing percentage 100% compared to T1 62.5%, 62.5% and 75% respectively, where is the differences was not significant in other traits. Blood parameters was showed significant (p<0.05) increase in glucose 67.91±2.06 mg/dl as compared to T1 59.25±1.72mg/dL, triglyceride was decreased significantly (p<0.05) in T2 42.66±0.96 mg/dl compared to T1 47.37±1.38 mg/dl. Concentration of AST enzyme was decreased (p<0.

This study was conducted in research department of animal resource/ Al-Rashidiya, at ministry of agriculture by using 14 of genetically improved awassi ewes, average body weight 56.00 ± 2.10 kg and age ranged between 3-5 years. Ewes were allocated according to their weight and milk production into two groups. The first was control (T1), fed on ration consist mainly of untreated barley and contain 9.69% of degradable protein and 3.77% of undegradable protein as dry matter. The second group (T2) was fed on same control ration but barley grain were treated with formaldehyde and contain 9.63% degradable protein and 6.37% of undegradable protein as dry

This study investigated the effect of feeding two levels of rumen degradable protein in the rations during different stages of lactation on milk yield and components , twenty four cross breed Awassi ewes (Turkish Awassi × Iraqi Awassi) were used with their single lambs after birth aged 3-5 years, ewes were divided into two groups with average body weights 66.00 ± 2.32 kg and 67.10 ± 2.62 kg respectively, first group was control fed adequate level of degradable protein (10 g / Mj metabolizable energy) and second group fed high level of degradable protein (12.5 g / Mj metablizable energy) , Lactation period had been divided into three stages (early, 1-50 day ), ( mid , 51-100 day) and (late , 101-150 day), ewes were fed twice daily with restricted amount 2 kg in the early and mid and 1.5 kg in late lactation . Results showed that feeding adequate level of rumen degradable protein led to significant ( P< 0.05) increase in milk yield 785 g/day and lactose 5.81% as compared with high level 619 g/day and 5.58% respectively, also milk yield decreased ( P< 0.05) while milk fat increased ( P< 0.05) with advance milk period. Blood parameters were not affected significantly by feeding degradable protein while serum glucose, total protein and albumin decreased (P< 0.05) at late stage of milk production. Best results of interaction for rumen degradable protein and milk stages in milk yield and components yield were noted with feeding adequate level of rumen degradable protein in the early lactation.

This study was conducted in research department of animal resource / Al-Rashidiya, by using 21 of Awassi ewes in the last two months of gestation, ewes were divided according to their body weight, age and milk production during the previous season into three groups, daily feed intake in all groups was restricted with 1.5 kg / ewe on rations consist of barley, wheat bran, soybean meal, urea and straw. the first group was fed on ration contained barley untreated with formaldehyde (T1), while barley grain treated with formaldehyde in the ration of second group (T2), the third group fed on formaldehyde treated barley * *
