Effect of supplemental Mn, Zn, Fe and Cu and their interactions on the performance of broiler chickens
Based on the results of the analysis of feed materials on the content of micronutrient elements and conducting scientific experiments on broilers chicken, the most effective source of Manganese, Zinc, Iron and Copper in mixed feeds, which contributes to solving the problem of increasing the quality of feeding and intensifying the growth of poultry has been substantiated. The optimum source of essential elements (Mn, Zn, Fe, Cu) for broilers chicken through feeds, the level of their incorporation into mixed fodders have been experimentally determined, and their influence on productivity and feed costs per 1 kg of body weight gain have been investigated. The tasks set in the work have been solved experimentally using analytical (analysis of literature sources), zoo-technical (growth indices, feed intake) and statistical (processing of the results obtained) methods of research. The use of mixed feeds in feeding broilers chicken which contained glycinate of Manganese, Zinc, Iron and Copper making 75 % of the needs, contributes to increasing their body weight by 2.5 % and increasing the growth rate by 2.4 %. Feed costs per 1 kg of broilers chicken growth were 1.5 % lower than the young bird index of the control group.
