Abstract

Probiotic preparations based on bacteria of different species composition, having the ability to increase the resistance and physiological status of the organism of the breeding object, are used to increase the productivity and preservation of the livestock of bred animals under the conditions of recent intensive cultivation technologies. The effectiveness of the probiotic complex A2 using to increase the productivity and quality of rabbit meat was studied by us. The studies were carried out in LLC "Lipetsk rabbit' on a hybrid livestock "Hypharm" of French selection at the age of 45 days. The experimental population was divided into control and experimental groups by the method of pair-analogues. The rabbits of the control group received PZK-92 compound feed, the livestock of the experimental groups was fed with PZK-92 compound feed with the introduction of the A2 probiotic complex in dosages of 0.6 and 1.0 g / kg of compound feed. When applying the optimal dosage of the used probiotic complex, which amounted to 0.6 g / kg of feed, 100% livestock safety is achieved, slaughter yield is increased by 4.51% with a decrease in feed costs by 1.42 ECE, as well as a positive effect on nutritional and biological value of rabbit meat was observed. An increase in profit by 3616.0 and profitability (up to 35%) by 12% in relation to the control group (23%) was achieved. This creates the prerequisites for the widespread use of this feed additive in the industrial complexes of the rabbit industry.
