Improving the productive performance of broiler chickens fed on diets containing the mixture "Toxbond Forte

Abstract

The study is conducted in Kosar's company experimental fields / Erbil to study the improvement of the carcass characteristics of broiler chickens, specifically those feeding on diets including "Toxbond Forte". The experiment lasted for 35 days and used 120 unsexed one day old chicks from Rose 308 type with an average of 42 ± 3 g per chick. The chicks were randomly classified into five treatments with three replications; each treatment had eight birds / replicate). The first treatment (T1) is called the control treatment in which the feed was without any addition, the second treatment (T2) included the addition of the compound with an average of 0.5 g / kg of feed, the third treatment (T3) included the addition of the mixture with a percentage higher than the second one, i.e. with a rate of 1 g / kg of feed, the fourth treatment (T4) included the rate of 1.5 g / kg of feed, and last treatment (T5) had the percentage of 2 g / kg of feed addition to the mixture. Results have shown that there are no big differences (p ≤ 0.05) in the relative weight of the main segments (chest and thigh piece), while the relative weight of the drumstick is significantly higher than the other treatments. Moreover, no differences have been seen for the secondary cuts, internal viscera and empty carcass weight, (p ≤ 0.05). Finally, the study has noted a significant difference (p ≤ 0.05) in the percentage of the net weight.
