The authors conducted the study based on the experimental quail farm SRDIAH SFSCA RAS (Siberian Research and Design Institute of Animal Husbandry Siberian Federal Scientific Center for Agrobiotechnology of the Russian Academy of Sciences) and at the Department of Obstetrics, Anatomy, and Histology of the Novosibirsk State Agrarian University. The study aims to change the content of micro- and macroelements in the blood of quails of the Japanese meat breed when using the Biocalcium feed additive. The productivity of animals depends on their health and is determined by their metabolism level. Birds, unlike other animals, have an intensive mineral metabolism.Calcium and phosphorus are two biologically active components with many functions that determine ana- and catabolic processes. When oviposition begins, the calcium and phosphorus concentration in chickens’ blood serum increases. But the rate of exchange of these macronutrients is determined by the activity of oviposition, so control over the content of these substances is relevant. Indicator enzymes that perform certain intracellular functions and enter the blood from the tissues are informative indicators for assessing metabolism. Using the activity index of alkaline phosphatase is reasonable to evaluate calcium-phosphorus metabolism. Using the feed additive Biocalcium in the blood of quail of the experimental group increased the calcium concentration by 0.2%. If we talk about zinc, iron, and magnesium indicators, they increased by 0.1-0.3%. It was also found that the introduction of fiber in feed rations had a definite effect on protein metabolism. During the experiment, it was found that the feed additive based on Siberian silver fir substrate Biocalcium has no apparent negative impact on the body of the quail. The additive is effective at a late stage of rearing. The authors note an improvement in metabolism, the mineral composition of the blood is normalized; hematopoiesis is stimulated without changing the stability of hematopoiesis and the constancy of the blood composition due to the introduction of this feed additive into the diet of birds.

The positive effect of chelate compounds of trace elements on the chemical composition of quail meat is justified. The experience used quails of the Japanese breed, egg-meat direction in the amount of 280 heads. Inclusion of chelate compounds of iron and zinc in the diet of quails provides positive correction of physical and chemical indices of meat raw materials. The greatest effect was noted when Bioferron 0,2 ml/kg was introduced into the diet: in 37-day quails, the level of raw protein in meat exceeded the control values by 1,33% (at p≤0,01), the level of raw ash - by 0,41%; in 98-day quails, the level of raw meat protein increased by 1,08%, and relative to the control group - by 1,92% (at p≤0,001), the level of raw meat ash increased by 2,85%, and relative to the control group - by 1,54% (at p≤0,01). In samples of meat raw materials of quail, which received Biocinc, 0,2 ml/kg was noted as the most effective dose: the level of raw protein in meat in 37-day quail exceeded the control by 0,78%, the level of raw ash - by 0,27%; in 98-day quails, the level of raw meat protein increased by 0,85%, and relative to the control group - by 1,14% (at p≤0,01), the level of raw ash increased by 3,45%, and relative to the control group – by 2,00% (at p≤0,01). The highest level of quail in meat raw materials among the elements was in iron, zinc and manganese. The largest amount of digested manganese in the muscles of 37-day quail was noted in a sample of the 5th experimental group (Biocinc 0,2 ml/kg) – 324,69% (p≤0,001) more than the control. In 98-day quails, the highest level of manganese accumulation was also noted in the sample of the 5th experimental group (Biocinc 0,2 mL/kg) – 306,25% (p≤0,001) more than the control one. In 37-day quails, the highest concentration of iron in meat raw materials (60,59±0,66 mg/kg at p≤0,001) was detected when Bioferron was included in the diet at a dose of 0,3 mL/kg, which is 156,63% more than the control. 98-day - 63,32±1,23 mg/kg (p≤0,001), which is 213,93% more than the control. The highest level of zinc was observed in the groups of 37-day quail, the diet of which included Biocinc at doses of 0,2 and 0,3 ml/kg, it was 43,30±0,95 and 44,49±1,41 mg/kg at p≤0,001, which is more than in the control group by 113,41 and 119,27%, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
