The effects of dietary biotechnological products of Saccharomices cerevisiae on growth performance, health status, and meat composition in broiler chickens

Abstract

The present study was conducted to investigate the effects of three biotechnological products of Saccharomyces cerevisiae(organic selenium, concentrated mannan of S. cerevisiae, and living cells of the same yeast) used in broiler diet on growth performance,health status, and meat quality and composition. One hundred day-old broiler chickens were divided into four groups (control and threeexperimental groups using the above-mentioned diet supplements) and fed basic feed mixture (developed by the Nutrition Departmentat the University of Agricultural Sciences and Veterinary Medicine in Cluj-Napoca, Romania) for 42 days. After this period, from eachgroup, five birds were sacrificed and measurements for slaughter yield, percent of different body parts, and chemical composition of meatwere determined. At the end of the research period (42 days), average values of corporal mass show very significant differences betweenthe experimental groups and the control group (P < 0.001). Registered data show that the administration of 0.03% organic seleniumin the broilers’ diet resulted in a significant difference (P < 0.001) in the meat content of selenium towards control. No significantdifferences in the chemical composition of breast meat were registered between the experimental groups. The results of the currentstudy indicate that different organic prebiotic and probiotics supplementation in broiler chickens’ diet improves growth performanceand affects immunological parameters (albumins and globulins). Organic selenium supplementation improves breast meat quality byincreasing the selenium level.
