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.

Highlights

Lack of efficacy of antibiotics in poultry breeding is indicated by many researchers
The feed additive, which is a mixture of phytoextracts, essential oils and protected organic acids, may be used as a safe alternative to growth-promoting feed antibiotics, as well as as an additional feed component of the diet of broiler-type chicken
Evidence for this is an improvement in the safety of the poultry units and its live weight, on the background of activation of lymphoid follicles in the spleen and weakly expressed involution processes in the bursa of Fabricius signifying strengthening of the cellular and humoral immune response of the poultry

Summary

Introduction

Lack of efficacy of antibiotics in poultry breeding is indicated by many researchers. It is emphasized that the tough environmental situation and unbalanced nutrition promote the spread of intestinal infections in poultry plants: salmonellosis, colibacteriosis, listeriosis. Antibiotics usage becomes ineffective and environmentally detrimental [1]. A WHO report, released in April 2014, noted that “this serious threat is no longer a prediction for the future. Antibiotic resistance–when bacteria change so antibiotics no longer work in people who need them to treat infections–is a major threat to public health” [2]. Misuse of antibiotics in breeding is a contributing factor to the emergence and spread of antibiotic-resistant micro-organisms. It is essential to limit the antibiotic use as a growth promoter in animal feed. It is essential to limit the antibiotic use as a growth promoter in animal feed. [3]
