The effectiveness of the use of the probiotic complex Subtilis-C in the field of industrial rabbit breeding

Abstract

For the successful development of the livestock industry, including rabbit breeding, it is necessary to reveal the genetic potential of breeding facilities by balancing feed rations and including dietary supplements in their composition that help maintain their homeostasis and reduce the negative impact of various stress and feed factors on the body of farm animals. Currently, there are a number of feed components that stimulate the productivity and growth of animals, birds, and animals. One of them are probiotic drugs that have a positive effect on strengthening immunity, strengthening health and increasing productivity of various types of farm animals. The aim of the work is to substantiate the effectiveness of the use of the probiotic drug Subtilis - C as part of a full-fledged granular compound feed for young rabbits to increase their meat productivity. To study the effect of the probiotic drug Subtilis - C, 45 rabbits aged 30 days were selected. Rabbits of the control group were fed according to the scheme adopted by the farm with a full-grain granular feed PZK-92 UAH, experimental groups of rabbits received feed rations based on the feed PZK-92 (obtained on the basis of cereals, sunflower cake, wheat bran, herbal flour from alfalfa and premix KVP P90-1K), which included probiotic the additive "Subtilis-S" (2 · 109) in a dosage of 0.6 and 1.0 g / kg of compound feed and hydrolysate of oats in a dosage of 2% as a binder instead of molasses. It is proved that the use of the probiotic drug "Subtilis-S" in a dosage of 1.0 g / kg by weight of compound feed increases the average daily gains and, as a consequence, meat productivity and protein content in the muscle tissue of rabbit carcasses.)
