Studies have shown that sheep of both breeds, whose diet included feed additives based on bentonite with chlorella and essential trace elements, outperformed their peers from the control group in some blood metabolites and morphological parameters. This indicates a higher level of metabolic processes in the body of animals of the experimental groups compared to the control, which is associated with the receipt of additional biologically active substances. It has been investigated that the use of a new feed additive leads to a significant improvement in growth and reduces LPO, namely, it reduces the content of MDA and DC in the blood, and the most positive effect of these complexes on the protein and carbohydrate metabolism of sheep of both groups during feeding. The average daily and absolute gains in live weight in the Hampshire and Kazakh meat wool breeds were 122 g and 6.80 kg and were also higher by 1.5 and 1.7%, respectively, than in the controls of both groups. The feed additive has a good adsorption and antioxidant effect, maintains balance, participates in the inactivation of free radicals and has a protective effect on cell membranes. The feed additive is high in calories, has an antioxidant and adaptogenic effect, increases animal weight, maintains a balance of biochemical and oxidative processes and can be recommended as a safe and effective supplement to the daily diet of farm animals. https://cjes.guilan.ac.ir/article_9588_2d06092ba20d5acd6c62bcaebae521f2.pdf
