Effects of dietary sodium butyrate supplementation on the intestinal morphological structure, absorptive function and gut flora in chickens
چکیده انگلیسی

A study was carried out to investigate the effects of dietary sodium butyrate (SB) on the intestine and growth performance in chickens. Three hundred and thirty six day-old AA broiler chicks were allocated at random into four groups with six replicates each. Four groups were fed with basal diet (control) or diets supplemented with SB at the level of 500, 1000, 2000 mg/kg. Body weight gain increased linearly during the period from 0 to 21 days as the dietary supplementation of SB increased (P<0.05). Dietary supplementation of SB influenced feed conversion ratio (FCR) in a positive quadratic fashion during the period from 0 to 42 days (P<0.05). Dietary SB did not influence the absorptive function of jejunum (P>0.05). The concentrations of DNA, RNA, and protein in duodenal mucosa showed negative quadratic responses to the increase of dietary SB supplementation level (P<0.05). The ratio of villus height to crypt depth increased linearly with the increase of dietary SB supplementation (P<0.01). The Lactobacillus count decreased linearly with the increase of dietary SB supplementation (P<0.01).
