Effects of dietary supplementation with palygorskite on intestinal integrity in weaned piglets
Abstract The effects of dietary supplementation of palygorskite on intestinal integrity in weaned piglets were investigated in this study. Pigs weaned at 24days of age (n=27) were allocated to three groups and fed the same basal diet supplemented with 0mg/kg (control), 2000mg/kg, or 3000mg/kg palygorskite for 42days. Three pigs from each treatment group were slaughtered for assessment of intestinal integrity on days 21 and 42. The results showed that both the feed/gain and the rate of diarrhea were decreased (P <0.05) with supplementation of 2000mg/kg palygorskite, and there were no significant differences between the two palygorskite-treated groups. Pigs fed palygorskite showed lower (P <0.05) plasma endotoxin and diamine oxidase concentrations on day 21. Compared with control, the villus diameters of duodenum (2000mg/kg group) and ileum (3000mg/kg group) were increased (P <0.05) on day 21, and villus height of the ileum was improved in the groups given palygorskite (P <0.05) on day 42. Lymphocyte numbers in the jejunum were increased (P <0.05) with dietary supplementation of 2000mg/kg palygorskite on day 42, compared with control. Palygorskite was shown to be beneficial to the intestinal integrity, which resulted in improving growth performance in weaned piglets.
Highlights Feed/gain and diarrhea rate were decreased with supplementation of palygorskite. Pigs fed palygorskite showed lower plasma endotoxin and diamine oxidase levels. Intestinal morphology in palygorskite-treated groups was improved. Palygorskite was effective in modifying the permeability of the intestinal mucosa.
