Impacto da utilização da parede celular de levedura Saccharomyces cerevisae sobre o desempenho e morfologia intestinal de frangos de corte

Abstract

Faced with a search for healthier food, a consummate population is beginning to restrict the purchase of meat from poultry fed diets containing antibiotics due to the emergence of resistant bacterial species. In view of this scenario emerges as an alternative to prebiotics, which are biologically safe compounds to human and animal health. The aim of this research was to evaluate the efficiency of the yeast cell wall Saccharomyces cerevisiae as a prebiotic. For that, 180 birds were distributed from a completely randomized design in three treatments and 8 replicates with 10 birds each repetition. Three types of diet, antimicrobial or prebiotic control (DC) were used using a 0.1% prebiotic (DC + 0.1%) and 0.15% prebiotic (DC + 0.15). %). Weight gain (kg / bird), feed intake (kg / bird), weight gain (kg / bird), feed conversion (kg /kg) / kg), viability 42 days old, two fractions of the duodenum, jejunum and ileum of 12 animals per treatment, being two birds of each repetition, for an analysis of the intestinal morphology. The birds that received the diet containing 0.1% prebiotic had better results at the end, so it can be concluded that the use of yeast cell wall of Saccharomyces cerevisae as prebiotic is an alternative to antimicrobial growth promoters.
