This study was conducted in fields of animal production / college of agriculture and forestry: university of Mosul for the period from 15 / 11 / 2021-15 / 2 / 2022, and the aim was to know effects of addition protected methionine and lysine on some blood pictures of Awassi lambs.

the initial weight of lambs was about 30.85-31.30 kg with ages 10-12 months where there were randomly distributed to four treatments at a rate of five lambs for each treatment.

the treatments were as follows, first treatment (control) T1: as Abasal diet, second treatment T2: added 1.5gm protected methionine / head / day to the basal diet, third treatment T3: added 3gm protected lysine / head / day to the basal diet, fourth treatment T4: added (1.5gm protected methionine + 3gm protected lysine / head / day to the basal diet and the treatment lasted 90 days, the protein content in the ration was 13.76%, and the energy level was (2520) kilocalories / kg of feed.

the results of the statistical analysis showed a significant decrease (P ≤ 0.05) in the number of white blood cells for the secondt2, third T3 and fourth T4 treatments compared to the control group T1 and a significant increase (P ≤ 0.05) in the concentration of globulin, cholesterol and triglycerides, and a decrease in urea and creatinine concentration in the fourth treatment T4 compared with the control treatment T1 and a significant increase (P ≤ 0.05) in albumin concentration in the addition treatments compared to the control.
