Abstract
The article discusses the possibility and effectiveness of using liquid energy feed based on propylene
glycol and glycerin (LEF) in combination with dihydroquercetin and Spirulina Platensis
microalgae as an additive to the diet of sheep to optimize inter-daily processes in the pre-pancreas,
increase natural resistance, improve intestinal and scar microbiocenosis.
It was found that the studied additive contributed to a more intensive hydrolysis of carbohydrates
in the rumen of animals due to an increase in the concentration of VFA by 45,2% versus
30,9% in the control, an increase in the content of lysozyme in the blood serum of sheep of the
experimental group by 35,38%, (p≥0,1), an increase in phagocytic activity, its index and number by
4,5; 3,9 and 15,8%, respectively, which indicates a more stable cellular immunity, increased resistance
of the body to infectious and inflammatory processes, and an increase in natural resistance.
The level of lacto- and bifidobacteria was 15,4–17% higher (p≥0,001), and yeast-like microorganisms
and molds, respectively, were 7,6% and 17,3% lower, which positively affected the microbiocenosis
of the intestines of animals.
