Technological aspects of increasing the meat productivity of rabbits using an adsorbent with a probiotic component SYMBITOX

Abstract

In this study, we assessed the effectiveness of using the feed additive Symbitox with probiotic–sorbent properties in rearing hybrid Hycol rabbits. Experimental studies were conducted in 2023 at an industrial rabbit breeding complex, Lipetsk Rabbit LLC, on a group of hybrid rabbit offspring selected at 30 days old after weaning from does. The animals were divided into groups using the pairwise comparison method, with 15 clinically healthy animals per group. Individuals in the control group were kept on a standard farm diet with PZK-94 GRN compound feed. Individuals in the experimental groups received PZK-94 GRN compound feed with varying amounts of the adsorbent Symbitox according to the research scheme: group 1 (control), group 2 (PZK + Symbitox 1.0 kg/ton of feed), and group 3 (PZK + Symbitox 2.0 kg/ton of feed). The effectiveness of using the feed additive Symbitox on the growth performance of rabbit offspring was confirmed. We established that rabbits in group 1 (control) lagged behind the animals in the experimental groups in terms of carcass weight: by 290 g (18.12%) for group 2 and by 407.0 g (25.43%) for group 3. The maximum slaughter yield was recorded in group 3 (dosage of 2.0 kg/ton of feed) and exceeded the control group indicator by 10.90%. Thus, the investigated feed additive Symbitox is a promising animal-feeding resource that increases rabbits’ productive performance in the industrial rabbit breeding industry.
