THE SOURCES OF NONCONVENTIONAL FEED ADDITIVES AND THEIR USEFUL PROPERTIES
The research objective was the definition of chemical composition of nonconventional feed additives. The research problems were: 1) to study chemical composition of nonconventional feed additives; 2) to define the influence of belite slime and oxidized brown coal on the dynamics of live mass of white mice. The research was conducted in 2018 on the Department of Animal Breeding and Production Technology of Livestock Products of the Institute of Applied Biotechnology and Veterinary Medicine of Krasnoyarsk SAU. The objects of the research were nonconventional feed additives. The research was conducted in complex with using the device of the infrared Infralyum analyzer. Experimental data were processed by the method of zootechnical analysis (laboratory method). For carrying out the experiment 3 groups of adult females of white mice up to 10 heads in each group, one control and two experimental were made. The groups were formed by the principle of the couple’s analogs taking into account the sex, age, live weight, development level of and the state of health. The selection of couples analogs was carried out, using A.I. Ovsyannikov technique. (1976). Control group received the main diet (MD) which included the following components: oats, wheat, grain corn, white bread, table salt, carrots and beet. In the first experimental group the replacement of 1 % of mineral part of the main diet by belite slime was made. In the second experimental group the replacement of 5 % of mineral part of the main diet by oxidized brown coal was performed. Live weight in experimental groups by the end of experiment increased in comparison with control group by 4.8 and by 7.9 g that made 18.1 and 28.4 %, respectively (P ≥ 0.999). Nonconventional feed additives containing a large number of mineral elements had positive impact on the gain of live mass of laboratory animals (white mice).
