Prospects for the use of probiotic dietary supplements in compound feed for young rabbits

The effectiveness of the feed additive "Enzimsporin", which has probiotic properties, was assessed in the process of fattening young rabbits of the hybrid breed "Hikol" in the industrial conditions of a rabbit breeding complex. The experiment was conducted in 2024 at the Lipetsk Rabbit LLC, where groups of clinically healthy animals were formed, selected at the age of 30 days after separating from female rabbits using the pair-analog method. The control individuals received standard compound feed, while the experimental groups used the same compound feed with the addition of "Enzimsporin" in the amount of 0.6 kg / t and 0.8 kg / t. The results showed a positive effect of the additive on growth and weight characteristics. By the 90th day of the experiment, the rabbits of the third group exceeded their relatives from the control group by 319 g (12.94%), and also exceeded the animals of the second group by 148 g (6.00%). The slaughter weight of carcasses of rabbits of the third group consuming compound feed with the introduction of 0.8 kg of the probiotic preparation "Enzimsporin" per 1 ton of compound feed exceeded this indicator relative to the control group by 264 g or 18.11%. The use of the feed probiotic "Enzimsporin" contributed to the accumulation of crude protein in muscle and a decrease in the mass fraction of fat in carcasses, this was especially clearly seen in the fleshy part of the carcasses of individuals of the 3rd group. As for the ash content, no reliably significant difference was recorded in the carcasses of all groups. Therefore, the use of "Enzimsporin" is a promising direction for increasing the productivity of rabbits in industrial rabbit breeding.
