The effect of enzyme preparations and lecithin on the blood picture of laying hens

Abstract

The use of new feed factors in poultry feeding is necessarily reflected in the change in blood parameters. The article presents the results of physiological studies on the study of changes in the hematological parameters of laying hens with the additional use of enzyme preparations Sanzaym and Sanfayz 5000, as well as lecithin in their feeding. Scientific and economic experience, during which the main physiological indicators were studied, was carried out in the State Unitary Enterprise of the Breeding Reproductor "Urus-Martanovsky" of the Chechen Republic on laying hens of the Loman Brown breed. As the main diet in the experiment, compound feed was used, prepared on the basis of corn, barley, wheat, sunflower meal. It was fed to a bird of the control group. In addition to the main diet, the livestock of the 1 experimental group were additionally fed two enzyme preparations: Sanzaym (100 g/t of feed) and Sanfayz 5000 (80 g/t of feed). Phospholipid lecithin, in the amount of 10 g/kg of feed, was fed to livestock. The use of enzyme preparations and lecithin increased egg production per average carrier by 24.5 pcs or 8.9%, the intensity of egg production by 7.42%, which made it possible to obtain 245.4 kg or 14.6% more egg mass than the control group.

Effect of Adding Natural Antioxidants in Compared to Vitamin E to the Diet on the Lipid Profile and Antioxidant Status of Laying Hens

“…The blood content of triglycerides and cholesterol is one of the important indicators that characterize the production of eggs in laying hens, and their accumulation in the blood is at high levels (higher than normal rates in the blood), It can be considered evidence of a decrease in the efficiency of using nutrients, especially fats, as a result of oxidative stress at the same time, a sharp decrease can be considered an indication of atrophy in the liver, or acute poisoning [32], This results in an imbalance in the bodies in general functional activity. [33]. Many studies have shown that astaxanthin is a naturally occurring carotenoid with antioxidant properties, so the combined effect of adding astaxanthin and magnolol at different concentrations to laying hens' diets may be the cause of the significant (P ≤ 0.05) decrease in blood serum cholesterol after using natural antioxidant supplements.…”
