The article deals with the study of the effect of synbiotic feed additive with pro-, prebiotic and sorption properties in the feeding of broiler chickens up to 37 days of age. The activity of specially selected specific bacterial strains of the feed additive increased due to the innovative approach to the selection of microbial strains composition, unique production method and lyophilic drying method. Adding the studied feed additive “Synbiosorb-2” in the amount of 0,10 % of the weight of the feed mixture proved to be the best dosage and increased the live weight of broiler chickens by 7,0 %, kept livestock by 3,0 %, muscle gain - by 25,4 % and reduced feed expenses per unit production by 6,8 %. Feeding synbiotic had a positive effect on the physiological and biochemical status of young poultry.
The aim of the research was to study the feeding of grain with triticale instead of barley in the amount of 10 and 15% of the Valentin-90 variety with the introduction of the Allzyme PT enzyme preparation in mixed feed for broiler chickens. An increase in the live weight of young poultry was established by 3.6-5.4%, a decrease in feed costs per unit of production by 4.5-5.6%, an increase in the safety of livestock - by 1.0-8.0%, an output of gutted carcasses by 0.5-0.6 abs. %, gutted - by 2.9 abs. %, muscle output - by 2.7-3.7 abs. %. Thus, the studied feeding schemes for broiler chickens can be recommended for production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
