Abstract
The purpose of the study is to study the influence of different vitamin-mineral supplement “Tekro” doses on biochemical parameters in blood plasma and liver of rabbits of New Zealand breed. The research methodology is based on research according to generally accepted research methods. Biochemical parameters were studied in rabbits’ organisms at 45, 60, 75 and 90 days of rearing with feeding of different doses of vitamin-mineral supplement “Tekro”, namely 3 %, 3.5 %, 4 %. The academic novelty is that nowadays the problem of the effect of different vitamin-mineral supplement “Tekro” doses on biochemical parameters in the blood and liver of rabbits has not been studied. Analyzing the indicators of the total protein content in the blood plasma of rabbits of the experimental groups and the control one for 90 days, it was noted that there was no significant difference in the indicators. In the liver of rabbits of the age from 45 to 90 days there was a tendency to increase the protein content due to the effects on the body of various doses of vitamin and mineral supplement “Tekro”. It has been established the positive effect of vitamin-mineral supplement “Tekro” on ALT activity of rabbits in experimental groups. At the age of 75 days, significantly higher ALT activity was recorded in rabbits of the 3rd experimental group by 35.8 % compared to animals in the control group.
