Abstract

This experiment was conducted to study the effects of vitamin B₁ on nutrient digestibility, intestinal morphology and microbial flora of geese aged from 5 to 15 weeks. Three hundred and sixty five-week-old Qingnonghui geese were randomly divided into six treatments with six replicates per treatment and ten geese (half male and half female) per replicate. The levels of vitamin B₁ in each group were 0.8, 2.6, 4.4, 6.2, 8.0 and 9.8 mg/kg, respectively. The experiment lasted for 11 weeks. The results showed as follows: different levels of vitamin B₁ in diet significantly increased dietary nutrition digestibility of geese (P<0.01), and also significantly increased the intestinal length index (P<0.05) and the intestinal body index of intestinal segment (P<0.01) of geese at 15 weeks of age. The different vitamin B₁ levels in diet significantly decreased the number of Escherichia coli in cecum of geese at 15 weeks of age (P<0.05), and significantly increased the number of Bifidobacterium (P<0.05) and Lactobacillus (P<0.01) in cecum of geese at 15 weeks of age. The different vitamin B₁ levels in diet significantly increased villus height (P<0.05) and villus height/crypt depth (P<0.01), and reduced crypt depth and intestinal thickness of geese at 15 weeks of age. In conclusion, the appropriate vitamin B₁ level can promote intestinal development and proliferation of beneficial microorganisms of geese at 15 weeks of age. At the same time, intestinal morphology of geese is closely related to dietary nutrient availability.

Key words： vitamin B₁; geese; nutrient availability; digestive tract; flora; histology
