Abstract

The effect of carbohydrates in the drinking water of broiler chickens on Salmonella typhimurium colonization was evaluated. Results indicate that mannose and lactose (2.5%) significantly (P < 0.05) reduced intestinal colonization of S. typhimurium by at least one-half, as compared with dextrose, maltose, and sucrose. Lactose and mannose also significantly reduced (P < 0.01) the mean log10 number of S. typhimurium in the cecal contents. Although mannose was the most effective sugar at blocking colonization, lactose may be more practical because it is effective and costs much less than mannose. Provision of carbohydrates in the drinking water had no significant effect on weight gain. /// Se evaluó el efecto de los carbohidratos en el agua de bebida sobre la colonización de Salmonella typhimurium en pollos de engorde. Los resultados indicaron que la mannosa y la lactosa (2.5%) redujeron significantemente (P < 0.05), por lo menos a la mitad, la colonización intestinal de S. typhimurium, comparado con la dextrosa, maltosa y sucrosa. La lactosa y la mannosa también redujeron significantemente (P < 0.01) el número promedio ( log10) de S. typhimurium en el contenido cecal. Aunque la mannosa fue el azúcar más efectivo para bloquear la colonización, la lactosa puede ser un bloqueador de la colonización más práctico por su efectividad y su menor costo. La administración de carbohidratos en el agua de bebida no tuvo un efecto significante sobre la ganancia de peso.
