Abstract
During the development of artificial feeds main objective is focused on the balance and availability of essential nutrients, as well as the need for the addition of trace elements and biologically active substances, probiotics etc. Introducing new components into finished pelleted feed is difficult and inefficient. Given this, there is the problem of developing feed bases that can be made in small batches with the possibility of adding to it the test components directly in the manufacturing process. The feed base developed on the basis of the modified recipe of feed BM-1. Foodmixture tested on sturgeons in the RAS conditions. Fish meal (46%) was used as the primary protein source in the manufacture of food, meat and bone meal (7%), fodder yeast (10%) and sunflower meal (15%) were used as minor ingredients. The experimental groups of fish were formed: sterlet (age group 1+), sterlet (albino form; 1+), sterlet (2+), Siberian sturgeon (1+), reverse hybrid sterlet and bester SBS (1+). Positive results on the application of the experimental basic feedmixture were obtained in all the experimental groups of sturgeon. Siberian sturgeon and SBS showed the fastest rate of growth over the period of the experiment. The daily average their mass increase was about 0.5%. The feed conversion ratio of the experimental base The daily average its mass increase was about 0.5%. The daily average their mass increase was about 0.5%. Кормовой коэффициент экспериментальной базовой кормосмеси оказался близким 3. The feed conversion ratio of the experimental basic feedmixture was close 3. Designed feed successfully proved itself in researches on the use of number of feed additives such as Rhodothorulla carotinogenic yeast, immunomodulator DON-1R and zeolites as a source of trace elements.
