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 three experimental groups using the above-mentioned diet supplements) and fed basic feed mixture (developed by the Nutrition Department at the University of Agricultural Sciences and Veterinary Medicine in Cluj-Napoca, Romania) for 42 days. After this period, from each group, five birds were sacrificed and measurements for slaughter yield, percent of different body parts, and chemical composition of meat were determined. At the end of the research period (42 days), average values of corporal mass show very significant differences between the experimental groups and the control group (P < 0.001). Registered data show that the administration of 0.03% organic selenium in the broilers' diet resulted in a significant difference (P < 0.001) in the meat content of selenium towards control. No significant differences in the chemical composition of breast meat were registered between the experimental groups. The results of the current study indicate that different organic prebiotic and probiotics supplementation in broiler chickens? diet improves growth performance and affects immunological parameters (albumins and globulins). Organic selenium supplementation improves breast meat quality by increasing the selenium level.
