Abstract:
This study was conducted to study the effect of adding selenium and zinc individually and their mixture on the carcass characteristics of male Kurdi lambs. The study included 16 male Kurdi lambs aged between 4-5 months and weights between 20-23 kg, the animals were divided into four groups, 4 lambs per group. The first group (the control) was fed a regular fed without adding selenium and zinc, the second group was added selenium at a concentration of 0.5 mg/kg fed, and the third group was added with zinc at a concentration of 100 mg/kg fed, and the fourth group was added with selenium with zinc at a concentration of 0.5 + 100 mg. /kg fed respectively. The additives were given by gelatin capsules fed for 90 days. The results showed that some carcass traits improved significantly in the groups of adding selenium and zinc and their mixture compared to the control group, and there were no significant differences between the four treatments in the carcass clearance ratio and the physical separation of the thigh piece. We conclude from the above that the addition of selenium and zinc and their mixture led to an improvement in some carcass characteristics of male Kurdi lambs.
