The Effect of Adding Aspartic Acid in Drinking Water on the Productive Performance and the Percentage of Carcasses to Meat in Broiler-Type Ross 308

Abstract

This experiment was conducted in the poultry field of the Department of Animal Resources, College of Agriculture, Al-Qasim Green University, to study the effect of aspartic acid on the product characteristics and the percentages of cuts of broilers. In the experiment 135 birds were used, type 308 Rose, one day old, unsexed, with an average weight of 42 g / bird, and randomly distributed to three treatments, at the rate of three replications for each treatment, and each replicated 15 chicks, where aspartic acid was added to drinking water for the treatments according to the following ratios (T1 0 mg / Liters of water, T2 500 mg/liter of water, T3 700 mg/liter of water) as the results of the experiment showed a high significance for the T2 and T3 treatments compared to the T1 control treatment in live body weight for the third, fourth and fifth weeks, respectively, as well as the high significance of the T2 and T3 treatments compared to the control treatment in The weight gain characteristic of the second, third, fourth and fifth weeks, respectively, as well as in the characteristic of feed consumption. It was observed that there was a higher significance for the T2 and T3 treatments compared to the T1 control treatment for the first, second, and third weeks. As for the efficiency of the Food conversion, the significance was high for the T2 and T3 treatments compared to the control treatment for the first, third, and fourth weeks. Moreover, for the carcass cuts, the significance was high for the T2 treatment only for the chest and neckpieces only compared to the rest of the other treatments. So. We conclude from this experience that there are a benefit and importance to give aspartic acid to improving the product characteristics as well as the proportions of the meat chicken pieces.
