Modulation of Broiler Chicken Digesta pH, Viscosity and Crypth Depth by β-Glucan and Mannan Oligosaccharides (MOS)

Maintaining optimal intestinal environment is essential for proper feed digestion and nutrient absorption in poultry. This study was conducted to evaluate the effect of dietary supplementation with inactive yeast YP20 derived β-glucan and mannan oligosaccharides (MOS) on the intestinal environment of broiler chickens, particularly focusing on pH,viscosity, and crypth depth of digesta. A total of 6,000 day-old chicks (DOC) of the Lohmann strain. The birds were randomly distributed into three treatment groups, each consisting of 2000 birds: T0 (basal diet without supplementation), T1 (basal diet supplemented with 1 % inactive yeast YP20), and T2 (basal diet supplemented with 2 % inactive yeast YP20). 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 ,Meanwhile, the viscosity values were 21.50, 22.25, and 22.25 cP (centipoise) treatments and also the crypth depth values were 177.56, 196.44 and 176.84, respectively Statistical analysis indicated that there were no significant differences (p > 0.05) among treatments for either pH, crypth depth or viscosity. In conclusion, supplementation with inactive yeast YP20 up to a level of 20 kg/MT did not affect the modulating intestinal pH anddigesta viscosity of broiler chickens, suggesting that these additives can be included in broiler diets without negatively affecting intestinal physical.
