Аннотація: The probiotic "Entero-active", due to the formation of lactic and acetic acids, creates an unfavourable pH
environment for pathogenic microflora, stimulates the growth of intestinal normal flora, which has a positive effect on the
composition of the microbiocenosis. In addition, probiotic microorganisms produce biologically active substances, enzymes
and amino acids. The aim of the research was to investigate the digestion of feed nutrients by broiler chickens fed by the
probiotic supplement Entero-active. Optimal doses of probiotic feeding are determined on the basis of obtained results. The
influence of probiotic supplement on digestibility of feed nutrients, availability of amino acids and retention of mineral
elements of mixed fodder is established. Tendencies of changes in productivity and safety of poultry under the effect of
probiotic are revealed.
The broiler chickens fed by additive Entero-active have increased the digestibility of dry matter by 2.4% (P <0.01),
protein by 3.4% (P <0.001), fiber by 31.1% (P <0.001) and NFE by 4.0% (P <0.001) comparing with the control group.
According to our research, the application of probiotic supplement Entero-active for the broilers’ feeding increases
the availability of essential amino acids, i.e. lysine by 4.8%, histidine by 3.8%, arginine by 4.9%, threonine by 7.5%, valine by
4.1%, methionine by 2.6%, isoleucine by 7.6% compared with the control indicator. It was found the absorption of Ca, P, Mg,
Mn, and increases respectively, by 23.5%, 6.9%, 12.2%, and by 33.1% under the action of probiotics.
The Entero-active probiotic application in the diet of broiler chickens increases the pre-slaughter live weight by
16.7%, the weight of ungutted carcasses by 15.0% and gutted carcasses by 17.3%, feed costs per 1 kg increase by 12.9%,
relative to control.
Our studies have made it possible to identify certain patterns in the digestion of nutrients by poultry, depending on
the different doses of probiotic Entero-active used in their diets.
