Immune and antioxidant status of the body of lambs using brown algae <i>Fucus vesiculosus </i>

Abstract

Relevance. In conditions of intensive animal husbandry, it is important to normalize the immune and antioxidant systems of the animal organism. Seaweeds can be used to increase the natural resistance of the animal organism to adverse environmental factors at an early stage of ontogenesis in the post-milk growing period.Methods. The research was conducted at the Federal Research Center for Animal Husbandry named after Academy Member L.K. Ernst , on two groups of lambs with analogues in live weight and age (n = 8). Lambs of the experimental group received 3 g of brown algae F. Vesiculosus in addition to the diet. The duration of the experiment was 27 days with the study of the aftereffect after 28 days with individual weighing of lambs.Results. The live weight of lambs whose diet used brown algae was 14 kg, which is 5.3% higher than in the control.According to microbiological indicators of blood, there was a higher level of bactericidal activity in lambs treated with brown algae, the difference was 28.33%. The content of TBА-active products in blood serum was higher in animals of the control group by 14.57%, the difference in TAWA in the blood of animals was 16.93% in favor of animals of the experimental group. The absolute increase in live weight in the experimental group 28 days after the experiment was 17.9 kg, which is 7.8% higher than in the control group.
