Improving the metabolic status and increasing the productivity of weaning pigs using daurian larch bark extract in the diet

The article presents materials from research work on the use of Dahurian larch bark extract ("ExtraCor") in the nutrition of weaned piglets, as an activation of metabolic processes and the prevention of diarrhea. The content of glucose, cholesterol and triglycerides in the blood serum may indicate the predominance of carbohydrates in the use of the body for energy purposes in piglets of the experimental group, and lipids in piglets of the control group. Changes in metabolism in piglets of the experimental group had a positive effect on the productivity and safety of the livestock. Thus, during the 70-day period of application of Daurian larch bark extract, the gross growth of piglets was 33.1 kg with an average daily gain of 473 g versus 28.1 kg and 416 g, respectively, in the control, which was 13.7 % higher. During the experiment, all piglets in the control group experienced diarrhea, which necessitated the use of antibiotics and antidiarrheal medications. In this group, two piglets died, resulting in their survival rate of 80 %. In the experimental group, antibiotics were not used and its safety was 100 %.
