Rational use of fodder resources involves finding and introducing non-traditional types of fodder into the diet of animals. For a long time in animal husbandry, productivity stimulants have been used, which promote the process of conversion of feed nutrients into products and affect its quality. Many years of research have shown that increasing the efficiency of bioconversion of feed nutrients into rabbit products depends on the type of diet, level, and completeness of feeding. A promising reserve for the production of rabbit products under such conditions is the use in the diets of new generation feeds that have immunomodulatory, anti-infective and other effects. Probiotic is a biologically active supplement based on bacterial strains. Probiotics include typical representatives of the normal microflora of the large intestine of animals: bifidobacteria, lactic acid bacteria, streptococci. Probiotics are aimed at the competitive exclusion of opportunistic bacteria from the list of intestinal microflora, which distinguishes them from antibiotics. The experiment involved a population of rabbits of meat and skin productivity. Two groups of young rabbits (females) control and experimental (4 heads each) were formed. The basic diet for these groups was the same and consisted of compound feed PC 90 Lux, manufactured by KreMix LLC. The difference in feeding between groups of rabbits was the additional introduction to the main diet of rabbits of the experimental group of probiotics "Enteronormin Detox" produced by LLC "Agricultural Enterprise" Microbiological Systems at the rate of 0.5 g per 1 kg (according to the manufacturer's recommendations). The probiotic contained the bacteria Enterococcus spp. 1–5 × 107 CFU / g, Bacillus subtilis spp. 1–5 × 106 CFU / g, Lactobacillus spp. 1–5 × 106 CFU / g, chitosan, yeast autolysate, ground mustard, ground garlic, ground cinnamon, zeolite. Preliminary assessment of the chemical composition and quality of feed. The use of the probiotic has improved the resistance of animals and increased preservation during the rearing period and has had a positive effect on the growing intensity and meat productivity of rabbits. |
