Effect of bio calcium feed additive on the biochemical status of quail blood

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.
