Abstract
The effects of chitosan on various metabolic and digestive processes in the animal body are an important to study because of the production quality for animal nutrition, healthcare, etc. The major known changes in the biochemical parameters of the animal liquids (by chitosan usage as feed additive) are the following: ratio of volatile and fatty acids, content of fat, mineral composition, etc. The aim of this study was to evaluate the total amount of water-soluble antioxidants (TAWSA) of feed additives based on chitosan and high protein concentrate of microbiological synthesis and to assess the effect of these feed additives on TAWSA values of sheep blood serum by amperometric method. Firstly, the antioxidant activity of feed components based on chitosan or/and a high-protein microbiological synthesis concentrate was studied in this work. Second, the experiments are carried out on XNUMX fistula animals to confirm the results of laboratory studies. Third, the determination of the total antioxidant activity of sheep blood by using chitosan additives (as the feed components) by amperometric method was carried out. A particular difference in antioxidant activity of the control and experimental samples of the sheep blood was established for the first time.
