To evaluate the effectiveness of the “Enzimsporin” probiotic preparation together with grass meal from Jerusalem artichoke green mass for feeding young rabbits, 200 French “Hypharm” rabbits (males) rabbits (males) were selected in the conditions of the “Lipetsk rabbit” LLC industrial complex, which are 45 days old on the principle groups – analogues were divided into 2 groups. Fattening was carried out until the age of 105 days. Rabbits of the 1st group (control) received mixed feed without additives, rabbits of the 2nd group were additionally injected with the probiotic preparation “Enzimsporin” 1.0 g/kg of mixed feed and a sorbent-toxin neutralizer “Fungistat-GPK” 2.0 g / kg mixed feed along with grass meal from green mass of Jerusalem artichoke in an optimally selected dosage of 15% by weight of the mixed feed. Upon reaching the age of 105 days, rabbits of the 1st group (control) were characterized by live weight, which was less than the weight of individuals of the 2nd group - by 284.0 g or 9.80%. The safety of the livestock in the control group was 90%, in the 2nd group 100%. An analysis of the morphological composition of rabbit carcasses showed that the use of the studied feed additives contributes to a more intensive growth of muscle tissue and an increase in the quality indicators and nutritional value of the obtained raw meat. Thus, the “Enzimsporin” preparation together with herbal flour from the green mass of Jerusalem artichoke is a promising product from a number of probiotics used in animal feeding and can increase the productivity and quality of rabbit meat.
