Productivity and biochemical status in quails under stress conditions when using calamus root in feeding

The article shows the results of studying the effect of preparations based on calamus root on the productive qualities (the time before the egg-laying stage and the number of eggs laid per day) and the biochemical status of quails under conditions of experimental complex stress: transport, compacted planting, light deprivation, temperature stress. The relevance of the study is justified by the fact that at present industrial technologies of keeping are used in quail farming, which are accompanied by a number of stress factors. Therefore, it is necessary to develop methods for correcting stress-induced metabolic disorders, which, undoubtedly, should decrease the time before the egg-laying stage and increase the amount of laid eggs. The study revealed normalization of the biochemical status of quails treated with the preparations based on calamus root, which is explained by its rich mineral composition. Thus, in quails of the 1st group, the glucose level decreases by 6.9%, in the 2nd-by 4.4%, in 3-1-by 8.6%. It is noted that by the end of the experiment, the iron level in the 3 experimental groups becomes significantly higher: in the 1st experimental group by 58%, in the 2nd by 61%, in the 3rd by 56% and reaches the norm. The cholesterol content decreases in the 1st group - by 2%, in the 2nd - by 8.5%, in the 3rd - by 15%. We have established a positive effect of preparations based on calamus root on the productive qualities of quails. It was found out that the introduction of calamus root infusion at a dose of 0.25 ml per head per day, the time before the egg-laying stage compared to the control group decreases: in the 2 group - by 20 days; in the 3 group - by 19 days, which increases the number of eggs laid per year.
