Effects of extrusion and supplementation of exogenous enzymes to diets containing Chinese storage brown rice on the carbohydrase activity in the digestive tract of piglets.
J Anim Physiol Anim Nutr (Berl). 2010 Apr; 94(2):146-53.JA

Abstract

Two experiments were conducted to study the effects of extrusion of Chinese storage brown rice and of exogenous enzymes supplementation to diets containing Chinese storage brown rice on the carbohydrase activity in digestive tract of piglets. In Experiment 1, 96 weaned piglets [initially 6.95 +/- 0.05 kg body weight (BW)] were used in a 2 x 2 factorial design, the animals were fed the diets containing extruded Chinese storage brown rice or non-treated Chinese storage brown rice and supplemented with or without exogenous enzymes. Each treatment had six replicate pens and four piglets in each pen. The results demonstrated that extrusion significantly increased (p < 0.05) the activity of duodenal maltase after 14 days of treatment and glucoamylase after 28 days of treatment, jejunal lactase, maltase, isomaltase, sucrase and alpha-amylase after 28 days of treatment, and jejunal alpha-amylase after 14 days of treatment; enzyme supplementation positively influenced (p < 0.05) the activity of pancreatic alpha-amylase after 14 and 28 days of treatment, pancreatic glucoamylase after 28 days of treatment and ileal trehalase after 14 days of treatment. Similarly, interaction between extrusion and enzyme addition existed after 14 days of treatment on the activity of pancreatic alpha-amylase and duodenal maltase and on the activity of duodenal glucoamylase and isomaltase, jejunal alpha-amylase, lactase, maltase, isomaltase and jejunal alpha-amylase after 28 days of treatment. In Experiment 2, six piglets (initially 21 +/- 1.85 kg BW) fitted with ileal 'T'-cannulas in a 6 x 6 Latin Square Design were used to study the effects of extrusion and addition of exogenous enzymes on ileal carbohydrase activity and nutrients digestibility. The results showed that exogenous enzymes significantly (p < 0.05) increased ileal alpha-amylase, glucoamylase and trehalase activity. The interaction between extrusion and enzyme supplementation had positive effect (p < 0.05) on the ileal lactase, cellobiase and sucrase activity.
