Abstract
The experiment was conducted in the fields of the Department of Animal Production - College of Agriculture - University of Tikrit for a period of 38 days. Tartikelle was replaced with yellow corn after the naturalization of one-day-old chicks, and it was fortified with a mixture of enzymes to see the extent of its effect on some chemo-biological characteristics of the blood serum of broiler chickens. 288 ROSS 308 birds were used, with an initial weight of 43 g. The chicks were distributed into six treatments, and each treatment had six replicates with 8 birds per replicate (three replicates males and the same number of females), and the treatments were as follows, the first treatment (T1) represented the control treatment without any addition (control negative). The second and third treatment (T2 and T3) partial and total replacement of corn by 50% and 100%, respectively. As for the treatments T4, T5 and T6, they are similar to the treatments T1, T2 and T3, respectively, with the addition of the enzyme mixture in an amount of 500 g / ton, according to the manufacturer’s recommendations. We note that there is a significant increase in the sixth treatment compared to the first treatment, and gender had no significant effect on the mentioned characteristics. In terms of the interaction between the experimental treatments and gender, the fourth treatment, females, was significantly superior in calcium concentration over the second and third treatments, males. The sixth treatment, males, outperformed the first and fifth treatments, males and the third. Males and females in York lions. As for blood glucose, the first treatment, females, decreased significantly in comparison with the rest of the experimental treatments. The first treatment was significantly superior to the second in serum albumin concentration. Gender did not have any significant effect. As for the interaction, the first treatment, males, decreased significantly in comparison with the second and fifth treatment, males, as well as with the second treatment, females, in total protein concentration. Blood serum on the first and second treatments were males and the fifth were females, and the second treatment was significantly superior to the first, fifth and sixth treatments in cholesterol, and the sixth treatment was significantly superior to all the experimental treatments in triglycerides, and the second and sixth treatments were significantly superior in HDL to the first and fifth treatments. Effect on the characteristic of cholesterol. As for the triglycerides and HDL, the males were significantly superior to the females. As for the overlap, the second treatment, males, was significantly superior in cholesterol over the first, males, and the first and sixth, females. As for the triglycerides, the sixth treatment was superior to males compared to all the treatments of the experiment, as well as the second and sixth treatments outperformed males in HDL on the fifth males and the first, fourth and fifth females.
