Abstract

The effectiveness of the use of a complex feed additive, consisting of blue-green algae spirulina and the antioxidant dihydroquercetin “Ecostimul-2” in the diet of pigs and its effect on the productivity and clinical and physiological condition of animals was studied. The inclusion in the diet of pigs of spirulina at a dose of 3 mg per 1 kg of live weight and dihydroquercetin - 1,5 mg per 1 kg of live weight positively affected the phagocytic activity of animal blood, which in the experimental group was 3,8% higher compared to the control lysozyme activity was higher by 17,9%. The average daily gain in live weight of pigs in the experimental group was 13,3% higher than that in the control group. The animals of the experimental group were less sick and the safety of the livestock in this group was 100%, in the control group - 90%.
