Abstract

This study was conducted to evaluate the effect of dietary supplementation with Beta-glucan and mannan oligosaccharides (MOS) on the intestinal environment of broiler chickens, particularly focusing on pH and viscosity of digesta. A total of 6,000 day-old chicks (DOC) of the Lohmann strain were produced by PT. Charoen Pokphand Indonesia were reared in a closed-house system under controlled temperature and humidity to ensure optimal environmental conditions. The birds were randomly distributed into three treatment groups, each consisting of 2000 birds: T0 (basal diet without supplementation), T1 (basal diet supplemented with 10 kg/MT Beta-glucan and MOS), and T2 (basal diet supplemented with 20 kg/MT Beta-glucan and MOS). The trial lasted for five weeks, after which samples of intestinal digesta were collected for laboratory analysis. The results showed that the average pH values were 5.58, 5.23, and 5.47 for T0, T1, and T2, respectively. Meanwhile, the viscosity values were 21.50, 22.25, and 22.25 cP for the respective treatments. Statistical analysis indicated that there were no significant differences among treatments for either pH or viscosity. In conclusion, supplementation with Beta-glucan and MOS up to a level of 20 kg/MT did not significantly alter the intestinal pH or digesta viscosity of broiler chickens, suggesting that these additives can be included in broiler diets without negatively affecting intestinal physical parameters.
