Use of propolis and rhodiola rosa boluses in corps with iron deficiency

The article presents the results of an experiment on the problem of iron deficiency anemia in Holstein cows kept in an industrial complex. Iron deficiency anemia is a common disease among dairy cattle, especially among highly productive breeds such as Holstein cattle. Iron deficiency leads to a decrease in animal productivity, a deterioration in milk quality and a decrease in the overall viability of livestock. The use of traditional methods of treatment using synthetic drugs is often accompanied by a number of side effects, including allergic reactions and intestinal microflora disorders. This necessitates the development of new approaches to iron deficiency correction based on the use of natural herbal preparations. The studies were conducted on animals of the second lactation (one month after calving), in which a low serum iron content was found in the blood. The cows of the control group had the main diet of the farm without the use of additional means of substitution therapy, as a means to correct iron deficiency conditions, the cows of the first experimental group were given propolis-based boluses to the main diet during morning feeding, and the animals of the second experimental group were given the main diet and boluses based on propolis and Rhodiola rosea. Boluses were given once a day for 35 days along with the feed. The monitoring of etiological factors makes it possible to use a biologically active supplement in the form of boluses based on natural ingredients that have a rich vitamin and mineral profile and have pronounced antioxidant and adaptogenic effects as an effective means of combating microelementosis.
