Influence of a complex feed additive on increasing the productivity of broiler chickens

Abstract

The purpose of the research was to study the eff ect of the complex feed additive “Zaslon 2+” as part of the basic diet on the growth rates of broiler chickens of the cross Ross 308, livability, productive traits and economic indicators. The scientifi c novelty of the research was to substantiate the possibility of increasing the productivity and livability of broiler chickens when using the complex feed additive “Zaslon 2+” in the diet. Comprehensive studies have been conducted to increase meat productivity through the use of a sorption feed additive with phyto- and probiotic properties “Zaslon 2+” with the basic diet. The research was carried out on broiler chickens of the cross Ross 308 under the conditions of the peasant farm “Krasnoe Podvorye” in the Shebekinsky area in the Belgorod region. During the experiment, the basic diet was used in the control group of broiler chickens. For the poultry of the experimental group during the 38-day study period the complex feed additive “Zaslon 2+” (0,5 kg/t of compound feed) was used to the basic diet. The infl uence of the studied feed additive in the diet of broiler chickens on the indicators of meat productivity, livability, and economic effi ciency of production was substantiated. The dynamics of live weight of poultry, growth intensity, uniformity, livability, morphological and biochemical parameters of chicken blood were studied. A comparative analysis of the meat traits of broilers was carried out, the chemical composition of the muscles and liver of poultry was determined, the eff ectiveness of the use of the complex feed additive “Zaslon 2+” in the diets of broiler chickens of the cross Ross 308 was determined. It was recommended, in order to increase productivity, uniformity, livability, activation of metabolic processes, improvement of the meat qualities of broiler chickens of the cross Ross 308, to reduce expenditures of feed per 1 kg of products, to introduce into the diet the complex feed additive “Zaslon 2+” in the amount of 0,5 kg/t of compound feed during the entire growing period.
