Abstract
The purpose of the study is to evaluate the effectiveness of the use of granular compound feeds with the introduction of probiotic preparation «Prostor», «Sporotermin» and sorbent «Fungistat-GPK» for fattening young rabbits. Studies of the effectiveness of full-size granulated feed were conducted on a population of young rabbits at the age of 45 days, selected according to the principle of groups of analogues and divided into 3 groups in the conditions of a private farm "O. V. Kuznetsova" 15 individuals were selected in each group. The live weight of the experimental groups exceeded the control group's peers when they reached age: 75 days by 85.0 and 251.0 g or 3.99 and 11.80%, 90 days - by 225, 0 and 435, 0 g or 9.04 and 17.49 % and 105 days-139.0 and 245.0 g or 4.37 and 7.70 %. The average daily increase in the control group was 26.55 g, in the experimental group 27.70 and 29.56 g, respectively. Hematological indicators of blood in the experimental groups indicate an increase in the number of red blood cells at the end of fattening (5,35-6,49 1012/l), and there is an increase in the total protein content in rabbits of the experimental groups to 75.82 and 75.99 g/l, which exceeds the values of this indicator of the control group by 3.45 and 0.17 g/l or 4.75 and 0.23%. This trend indicates an intensification of metabolic processes and the possible receipt of the largest increases in live weight. It was found that rabbits of the experimental groups had a slaughter yield of 63.01 and 65.03%, which exceeded the values of this indicator (56.84%) of the control group. The inclusion of enriched compound feeds in feed rations will help to improve the safety and productivity of reared rabbits and creates prerequisites for the large-scale use of these feed resources in the conditions of industrial rabbit breeding.
