Starch with high amylose and low in vitro digestibility increases short-chain fatty acid absorption, reduces peak insulin secretion, and modulates incretin secretion in pigs.

Diets containing different starch types affect peripheral glucose and insulin responses. However, the role of starch chemistry in kinetics of nutrient absorption and insulin and incretin secretion is poorly understood. Four portal vein-catheterized pigs (35.0 ± 0.2 kg body weight) consumed 4 diets containing 70% purified starch [0-63.2% amylose content and 0.22 (slowly) to 1.06%/min (rapidly) m...

Enzymatically Modified Starch Favorably Modulated Intestinal Transit Time and Hindgut Fermentation in Growing Pigs

Aside from being used as stabilizing agents in many processed foods, chemically modified starches may act as functional dietary ingredients. Therefore, development of chemically modified starches that are less digestible in the upper intestinal segments and promote fermentation in the hindgut receives considerable attention. This study aimed to investigate the impact of an enzymatically modifie...

The Effect of Soybean Meal Heating Time on the in vitro Digestibility and Ruminal Fermentation Profile

The aim of this study was to determine the most optimal heating time in protection of protein rich feedstuff on digestibility and in vitro ruminal fermentation profile. Proteinous feedstuffs used in this study is soybean meal (Glycine max). This study is designed using one way ANOVA, with five treatments of heating time (T0 (control)= unheated, T1= 10 min, T2= 20 min, T3= 30 m...

Effect of Aflatoxin B1 on In Vitro Digestibility and Ruminal Fermentation of Sheep Diet

     The aim of this study was to investigate the effect of different levels of aflatoxin on the gas production, in vitro fermentation parameters, dry matter and organic matter digestibility of sheep's diet. This experiment was conducted in a completely randomized design with 5 treatments and 4 replicate per treatment. The treatments included 1.diet without aflatoxin and methanol (control), 2.c...

Hydroxypropylation of high-amylose maize starch changes digestion and fermentation-dependent parameters in rats

It was examined whether the physiological effects of high-amylose maize starch (HAMS) are influenced by hydroxypropylation. Rats were fed one of the following three diets: an AIN-93-based diet with waxy maize starch (WMS) as a starch source, or this diet with 150 g of WMS replaced by either HAMS or hydroxypropylated HAMS (HP-HAMS). The activities of amylase in bile-pancreatic juice and sucrose,...
