Influence of a complex preparation based on phytoextracts on productivity indicators and development of the immune organs of broiler-type chicken

Abstract

This research is devoted to studying the safety of livestock, live weight, mass of internal organs and morphohistological changes in the immune organs of broiler-type chicken when substituting antibiotic feed supplements in the diet and in combination with antibiotic growth stimulants, a feed additive including essential oils, protected organic acids (fumaric acid, sorbic acid, DL-malic acid, citric acid), and hot pepper extract. The experimental procedure was conducted at the production conditions of “Ptitsefabrika “Sredneuralskaya” OOO in broiler-type chicken “Ross 308” under the guidelines of the Federal Research Center “VNITIP” of the Russian Academy of Sciences (2013). Having conducted research, the positive effect of a complex preparation based on phytoextracts on the liveability of broiler-type chicken, their live weight, and on the development of the immune organs was determined.
