Replacing dietary starch with sugar has been reported to improve production in dairy cows. Two sets of 24 Holstein cows averaging 41 kg/d of milk were fed a covariate diet, blocked by days in milk, and randomly assigned in 2 phases to 4 groups of 6 cows each. Cows were fed experimental diets containing [dry matter (DM) basis]: 39% alfalfa silage, 21% corn silage, 21% rolled high-moisture shelle...

An experiment was conducted to compare different dietary vegetable sources of starch and protein on the coefficient of apparent total tract digestibility (CATTD) of energy and nutrients and performance of piglets from 29 to 60 d of age. The experiment was completely randomized with 6 treatments arranged factorially with 3 sources of starch (cooked-flaked corn, cooked-flaked rice, and pea starch...

OBJECTIVES The aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. Quasi-emulsion solvent diffusion was used as a crystal modification method. MATERIALS AND METHODS Corn starch was dissolved in hydrochloric acid at 80°C and then ethanol as a non-solvent was added with lowering temperature u...

Little is known about the effects of the composition of dietary carbohydrate on the development of left ventricular (LV) hypertrophy (LVH) and heart failure (HF) under conditions of pressure overload. The objective of this study was to determine the effect of carbohydrate composition on LVH, LV function, and mortality in a mouse model of chronic pressure overload. Male C57BL/6J mice of 6 wk of ...

Overview: Starch is the major component of cereal grains. In corn it makes up approximately 75% of its dry matter. Starch is a polymer with the simple sugar glucose serving as the repeating unit. Normally starch occurs in two forms: amylose, a linear molecule normally making up 25% of the starch, and amylopectin, a branched form comprising the remainder. For Missouri livestock growers, producer...

The aim of this study is to improve the Cold Water Solubility (CWS) and esterification activity of Native corn Starch (NS) by pretreatment NS using NaOH/urea aqueous solution. The influence of pretreatment on granule shape and crystal structure of corn starch was investigated by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). It has been found that the average particle size of P...

The objective of this experiment was to determine the relationship between corn kernel vitreousness and ruminal in situ starch degradation. Fourteen U.S. and five Brazilian corn hybrids cultivated in their respective countries were evaluated. The U.S. dent hybrids were harvested at one-half milk line, black layer, and 21 d after black layer stages of maturity. Brazilian flint hybrids were harve...

The effects of diets with different starch sources on the total tract apparent digestibility and glucose and insulin responses in cats were investigated. Six experimental diets consisting of 35% starch were extruded, each containing one of the following ingredients: cassava flour, brewers rice, corn, sorghum, peas, or lentils. The experiment was carried out on 36 cats with 6 replications per di...

A modified pesta granule was developed for Pseudomonas fluorescens BRG100, a bioherbicidal bacterium for grass weeds, green foxtail (Setaria viridis) and wild oat (Avena fatua). This study reports: i) the effect of formulation water activity (aw) on survival of P. fluorescens BRG100 and, ii) the effect of starch on disintegration and dispersal of a green fluorescent protein transformant of P. f...

Probiotics are commonly fed to dairy cattle to improve feed efficiency and increase milk yield. The objective of this study was to determine the effects of a probiotic, (Bovamine®; Nutrition Physiology Company, LLC. Guymon, OK) consisting of Lactobacillus acidophilus (LA) and Propionibacterium freudenreichii (PF), on the in vitro digestibility of starch and neutral detergent fiber (NDF). Starch...
