RESUMO
El estudio comparó parámetros productivos de pollos de carne suplementados con un probiótico Biomin® Poultry 5 Star (Enterococcus faecium, Pediococcus acidilactici, Bifidobacterium animalis, Lactobacillus salivarius y Lactobacillus reuteri) versus un antibiótico (Zinc Bacitracina). Se usaron 333 aves divididas en tres tratamientos de 111 animales con 3 repeticiones por tratamiento: 1, control; 2, antibiótico; y 3, probiótico. En las seis semanas de crianza no se encontró diferencia significativa entre tratamientos para peso corporal, consumo de alimento, conversión alimenticia (ICA), porcentaje de mortalidad y el índice de eficiencia productiva (IEP).
The present study compared productive parameters in broilers supplemented with a probiotic Biomin® Poultry 5 Star (Enterococcus faecium, Pediococcus acidilactici, Bifidobacterium animalis, Lactobacillus salivarius y Lactobacillus reuteri) versus an antibiotic (Bacitracin). A total of 333 chicks were divided into three treatments of 111 animals with 3 repetitions for group: 1 control; 2 antibiotic; 3 probiotic. During the six weeks of the study no statistical differences were found between treatments for body weight, feed consumption, feed conversion, mortality rate, and productive efficiency index.
