Effect of Treatment With a Mixture of Amino Acids at Different Levels on Some Biochemical Parameters and Wool, Carcass Characterizes in the Arabi Lambs Breed

A total of eighteen healthy lambs, divided randomly into three groups (six animals for each group) as follows: 1) control group, 2) T1 treated a mixed amino acid at a dose 10g/head orally, 3) T2 treated a mixture amino acid at a dose 20g/head orally, to investigate the effect of treatment with a mixture of amino acids on some biochemical parameters (albumin, cholesterol, glucose, Fe, Zn, TSH and thyroid hormone), wool growth (crude weight, clean weight and fiber length) and carcass trails (weights of the hot carcass, shoulders, legs, ribs, the fat tail, lion, heart, liver, lungs and kidney) in Arabi lambs. The results showed significant (P<0.05) differences among treated groups in some biochemical parameters such as albumin, cholesterol glucose, TSH and thyroid hormone. T2 group was higher in those parameters especially after 90 days of treatment compared with the other groups. No significant differences were presented between groups in the concentrations of Fe and Zn. Also, the results showed increased significantly (P<0.05) in wool and carcass characterizes when lams treated with 20g/head of mixture amino acid compared with other groups, in spite of, there were no significant differences between groups in some cuts such as the weights of lion, heart, liver, lungs and kidney.
