- Abstract
The aim of the present study was to investigate the effects of different combinations of dietary starch and non-starch polysaccharides (NSP) on intestinal functions, and lipid and glucose metabolism in pigs. Fifty-four weaned pigs weighing 6.71 ± 0.52 kg were randomly assigned according to body weight and sex to 3 treatments with 6 replicates per treatment and 3 pigs per replicate, and were fed: T1 diet containing starch with amylose/amylopectin (AM/AP) ratio of 1:1 and NSP 3% (a mixture of inulin and cellulose in a ratio 1:1), T2 diet with starch of AM/AP ratio 2:1 and NSP 1% or T3 diet containing starch with AM/AP ratio of 1:2 and NSP 2%. Pigs were fed experimental diets for 28 days. It was shown that in animals fed T1 diet mRNA expression of glucagonlike peptide-2, zonula occludens 1 and occludin (P < 0.05) were up-regulated and tended to be increased the mRNA level of insulin-like growth factor-1 (P = 0.06) in colon, the activity of lactase in jejunum was increased (P < 0.05), mRNA expression of insulin receptor substrate 1 and glucose-6-phosphatase in liver were improved (P < 0.05), and the activity of lipoprotein lipase (P < 0.05) was decreased and the activity of malate dehydrogenase tended to be enhanced (P = 0.07) in longissimus dorsi muscle. Feeding T1 diet promoted the intestinal functions and improved to some extent lipid and glucose metabolism in pigs. So, carbohydrates combination of starch with AM/AP ratio of 1:1 and NSP 3% can be recommended for weaned pigs.
