Performance indicators and broiler chicken livability when using yeast cell wall in feeding

Since 2006, the European Union has implemented a ban on the use of feed antibiotics in poultry farming, creating the need to find alternative methods for preventing infectious diseases in commercial poultry. The aim of this study was to evaluate the effectiveness of the prebiotic preparation "Ist Sel Vol", produced by "Angel Yeast LTD", whose active ingredient is a yeast cell wall derived from Saccharomyces cerevisiae, in broiler chicken production. An analysis of its impact on the growth and safety of broiler chickens was conducted. A production trial lasting 38 days was conducted on 74,410 "Cobb-500" broiler chickens, which were divided into two groups. The only difference between the experimental group and the control group was the addition of the prebiotic yeast cell wall preparation "Ist Sel Vol" at a dosage of 1 kg per ton of feed. At the end of the production cycle, a positive stimulatory effect of the tested preparation on the growth and development of broiler chickens was observed. As a result of using the yeast cell wall preparation, the average daily weight gain of broilers in the experimental group was 0.81% higher compared to the control group, and the average carcass weight of chickens from the experimental group was 1.17% higher than the average carcass weight of the control group. The application of the tested prebiotic also contributed to an improvement in feed conversion by 2.4%. The European Efficiency Factor in the experimental group was 3.3% higher than in the control group. Additionally, an increase in the livability rate by 0.5% was recorded in the experimental group. The obtained results demonstrate the effectiveness of the "Ist Sel Vol" yeast cell wall preparation in industrial broiler production and highlight its potential for preventing bacterial diseases and reducing the negative effects of mycotoxins in broiler farming.
