The influence of diets with dry corn barda and intermittent feeding mode on the productive and biological traits of broiler chickens

Abstract

The inclusion of dry corn barda in diets helps to solve the problem of obtaining inexpensive feed protein for broilers, but the effectiveness of its use in different doses has not been studied good enough. The use of different intermittent feeding programs, as of a intermittent feeding mode can reduce the severity of heat stress in broiler chickens. However, the optimal duration of the break in feeding broiler chickens in the hottest daytime hours is not established in detail. The purpose of the researches was to determine the effect of diets with dry corn barda and intermittent feeding mode with the addition of the complex of trace elements (chromium, zinc) and vitamins (ascorbic acid, antisterility vitamin) on the productive and biological characteristics of broiler chickens at high air temperature in the hot arid climate. The productive and biological trats of broiler chickens have been determined when using 5, 10, 15 % dry corn barda in diets. Data on the productive and biological parameters of broiler chickens of the cross Ross-308 have been obtained when using intermittent feeding mode of different duration (2, 3, 4 hours). New data have been obtained on the productive and biological parameters of broiler chickens cross Ross-308 when using additives in feed of different doses of trace elements (Cr, Zn) and vitamins (C, E). The optimal parameters of the duration of intermittent feeding mode and the dose of trace elements (Cr, Zn) and vitamins (C, E) added to the feed have been revealed. It has been found that the inclusion of dry corn barda in the diet of broiler chickens and the influence of intermittent feeding mode with the addition of the complex of trace elements (Cr, Zn) and vitamins (C, E) in the feed improves the functional state of the body and increases the productivity of broiler chickens at elevated air temperature in the hot arid climate.
