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 authors see energy components extremely relevant for animals and their health. Due to this fact, diets with energy components that satisfy pets with nutrients at different stages of growth is significant issue in veterinary nutrition. This could be achieved when applying diets that contain balanced necessary components. The research aimed at exploring the impact caused by ready diets on the growth and development of dogs that differ in age and breed is fragmentary one. The authors make a case about necessity for detailed investigation the growth parameters of animals when feeding them with this kind of diets in the low temperatures of Western Siberia. The impact of the finished ration on puppy growth and development was investigated in one of the s animal shelters in Novosibirsk in 2016. The main food used in the experiment for feeding puppies was YUMMI PREMIUM; the feed contains proteins - 26%, fats - 10, fiber - 7, ashes - 7, moisture - no more than 10, calcium – 1 and phosphorus - 0,8%. The authors observed that 50% are meat ingredients (beef, chicken, by-products), 35 are cereals (wheat, buckwheat), vegetable oils, dried milk and 5% are vegetables, chicken fat, mannanoligosaccharides (MOS), Shidiger yucca extract and sea kelp extract. The following food additives are included in the feed: Vitamin A (17000 IU/ kg), vitamin D3 (1700 IU/kg), vitamin E (200 mg/kg), B1 (15 mg/kg), B2 (20 mg/kg), B6, B12 (100 mg/kg), K3, niacin (85 mg/kg), pantothenic acid (50 mg/kg), biotin (950 µg/kg), iron, zinc, manganese, copper (20 mg/kg), iodine (2 mg/kg) and selenium (0.25 mg/kg). The food of the experiment was eaten by puppies with great pleasure. This experiment has shown that YUMMI PREMIUM for puppies increase body weight and average daily growth rates, as well as improve the main parameters of dogs development.
