This experiment was conducted in poultry fields of the department of animal production-college of agriculture-university of Kirkuk for the period from 20 / 3 / 2021 to 1 / 5 / 2021 for a period of 42 days (field work) the aim of this study was to determine the effect of betaine and taurine with the dl-methionine upon some blood biochemical parameters for broiler ross 308.

in this study, 350 chicks of broiler type ross 308 were used, not naturalized, at the age of one day, as the primary rate per chicken was 42 g, chickens were distributed from the first day to 7 feeding treatments, (50 birds/ treatment) with 5 replications/ treatment.

(1 replicate/ 10 birds), and each duplicate included 10 birds in a pen 35 with dimensions (90×190cm).

the results of the statistical analysis showed a significant increase in the concentration of agglutinated blood cells, as the third, fourth, fifth, sixth and seventh treatments were significant compared to the negative and positive control treatments.

as for hemoglobin concentration, the fourth, fifth, sixth and seventh treatments were significantly superior compared to the first, second, and third treatments did not differ from the second treatment.

as for white blood cells, the fourth, fifth, sixth and seventh treatment were significantly superior compared to the first and second treatments, and the third treatment did not differ from the second treatment, and in the concentration of red blood cells, the fourth, fifth, sixth and seventh treatment were significantly superior compared to the first and second treatments...

and the third treatment did not differ for the second transaction.

as for the biochemical blood characteristics, a significant (p ≤ 0.05) was found in the concentration of total protein in the blood serum, where the third, fourth, fifth, sixth and seventh treatments were superior compared to the negative and positive control treatments, as well as a significant decrease (p ≤ 0.05) in the serum cholesterol concentration of the treatments.

the third, fourth, fifth, sixth and seventh treatments compared to the negative and positive control treatments, as well as for the concentration of uric acid, as there was a significant decrease (p ≤ 0.05) for the third, fourth, fifth, sixth and seventh treatments compared to the negative and positive control treatments, and the third treatment did not differ with the second treatment, and the same was true for the concentration of glycerides we also notice a significant decrease (p ≤ 0.05) for the third, fourth, fifth, sixth and seventh treatments compared to the negative and positive control treatments.

the second treatment, as well as a significant decrease (p ≤ 0.05) in the level of amino enzyme (alanine transferase) for the fourth, fifth, sixth and seventh treatments compared to the negative control and the third treatment, and a significant decrease in the concentration of the enzyme aspartate aminotransferase was noticed for the fourth, fifth, sixth and seventh treatments compared to the negative control and the third treatment did not differ from the second treatment, either in the concentration of the enzyme (alkaline posphatase).

it was found that the third, fourth, fifth, sixth and seventh treatments were significantly superior compared to the negative and positive control treatments.
