The effect of the adaptogen betulin on the level of immunoglobulins in the blood serum of breeding calves and dairy cows

This article presents scientific data on the effect of a betulin-containing feed additive on immunoglobulin levels in calves and dairy cows under livestock farming conditions. The study examined data obtained from a study conducted on five- and ten-month-old calves and dairy cows, divided into experimental and control groups. At the beginning of the experiment, serum analysis revealed that immunoglobulin levels were below normal in some animals in both the control and experimental groups. During the study, a betulin-containing feed additive was added to the daily diet of animals in the experimental groups. The additive was administered orally at a dose of 10 mg/kg of body weight once daily for 14 days.

Repeat serum analyses of animals in the experimental and control groups revealed that, in animals in the experimental groups with initially low immunoglobulin levels, these values shifted from low to optimal by the end of the experiment, demonstrating positive dynamics across the group. However, similar indicators in animals in the control group remained unchanged.

It was established that the use of a supplement containing betulin affected the immune status of the experimental animals, indicating its immunostimulatory effect.
