Abstract/OtherAbstract:
A feeding trial was conducted to evaluate the effects of mannanoligosaccharide (MOS) on the growth performance, nutrient digestibility and gut development of broilers given a corn or a wheat-based diet over a 21-day experimental period. Dietary MOS improved the growth performance of birds given the wheat-based diet compared to that of birds given the corn-based diet during 7-21 days of age. In line with this, the ileal digestibility of starch was increased by MOS at 21 days of age. The addition of MOS modulated the development of gut microflora. From day 7 to day 21, the numbers of mucosa-associated coliforms along the small intestine were decreased; whereas the numbers of mucosa-associated lactobacilli were increased by MOS, regardless of the cereal type in the diets. Dietary MOS also reduced the counts of coliforms and Clostridium perfringens in the caeca of birds by 21 days of age. Villus height at the jejunum was not affected by MOS but the crypt depth and the muscularis thickness were reduced. The specific activities of maltase and alkaline phosphatase were increased in birds given the MOS-supplemented diet; whereas the development of leucine aminopeptidase was delayed by MOS. All these changes in the mucosal morphology and function were dependent on the type of cereal and/or the age of the birds.
