Effect of the blue-green microalgae Spirulina platensis and the antioxidant dihydroquercetin on metabolic health, colon microbiocenosis, and pig productivity

The article presents data on the use of natural Microalgae-Spirulina Platensis and dihy-droquercetin antioxidant in the cultivation of weaning pigs. The inclusion of feed additives in the diet contributed to the prevention of hyperbilirubinemia. The total bilirubin content in the blood serum of piglets receiving spirulina was lower by 5.4 %, and those receiving dihydroquercetin was lower by 4.3 % than in the control group of piglets. The pigs of the second experimental group showed a decrease in Alat and ASAT activity by 4.7 and 7.1 %, respectively, compared to the control group. The cholesterol content in the blood serum of piglets receiving feed additives was also lower than in the control group by 11.1 and 16.7 %, respectively. Feed additives had a positive effect on the microbiocenosis of the colon. In its contents, the number of streptococci in the second experimental group decreased by 6, 0x104 CFU compared to the control group. The average daily increase in live weight of pigs receiving only spirulina was higher by 11 % than in the control group. in the second experimental group receiving spirulina in combination with dihydroquercetin, it was higher by 13.3 %. In experimental groups of pigs, the safety was 100 %.
