The environmental-biology aspects of use of chitosan and ultrafine particles of copper and iron in the nutrition of broiler chickens

Abstract

The natural biopolymer chitosan is currently of great interest to specialists in the field of medicine and veterinary medicine due to properties such as biocompatibility, good sorption and low allergenicity. The aim of the study is to study the environmental-biology effect of chitosan and UFP on growth, productivity and morpho-biochemical blood parameters of broiler chickens. The study was performed on broiler chickens of «ArborAcres» cross (n = 60) in the conditions of vivarium. Biochemical studies of blood serum were performed using an automated analyzer CS-T240 (DIRUI Industrial Co., Ltd, China). The use of chitosan (group I) and UFP (group II) leads to a positive productive effect, however, the joint feeding with chitosan with UFP (group III) does not give a similar result. Feeding with chitosan-containing diet (group I) reduced the concentration of total cholesterol and triglycerides to a greater extent than the use of UFP (group II). Against the background of the introduction of chitosan into food (group I), the activity of catalase increased compared with that of the control. The level of malondialdehyde (MDA), as an indicator of lipid peroxidation, decreased with all variants of feed additives. The use of chitosan and UFP in the diets of broiler chickens is advisable and helps to normalize the metabolism and productivity of the bird. The results indicate a promising approach, and requires further research as a component that can be used in the industrial production of animal feed.
