A total of 3,632 crossbred steers were used in 3 separate randomized complete-block designed finishing experiments. Data from Exp. 1 were analyzed separately whereas data were combined for Exp. 2 and 3, based on corn processing method used [Exp.1 = equal combination of dry-rolled and high-moisture (DRC:HMC); Exp. 2 and 3 = steam-flaked (SFC)]. Steers were fed 1 of 5 treatments to evaluate the e...

Grains are fed to livestock primarily to supply energy, and most of the digestible energy in cereal grains comes from starch. To maximize starch digestion by livestock, corn and sorghum grain must be processed. For nonruminants, starch from finely ground grain is fully digested, but for ruminants fed high concentrate diets, finely ground grain often causes metabolic diseases. Hence, rather than...

Cereal Chem. 88(2):159–173 Corn can be fractioned to produce starch, fiber, oil, and protein in relatively pure forms. The corn kernel contains 9–12% protein, but half of this is an industrially useful protein called zein. Dry milled corn (DMC), corn gluten meal (CGM), and distiller’s dried grains with solubles (DDGS) are all coproducts from corn that contain zein and are used for zein extracti...

Bulk density is one of the important engineering property of biomass having significant impact on the supply logistics and processing in ethanol production facilities using lignocellulosic materials. Bulk density of most of the comminuted biomass significantly increased by tapping. Switchgrass, wheat straw and corn stover were chopped in a knife mill at different operating conditions including ...

The presence of a large amount root residues after harvesting corn creates problems for the processing field. On basis field and laboratory studies, character weediness main physical morphological characteristics rhizomes were revealed. Analysis variation curves dimensional mass graphical dependences made it possible to develop general approach freeing fields from plant corn.

Oftentimes, corn processors believe that ground corn (raw material) and distillers dried grains with solubles (DDGS) are interrelated in certain quality parameters. Yet, previous studies, although rather limited, have not established this relationship. In this study, six ground corn samples and their resulting DDGS were analyzed for particle size distribution (PSD), using a series of six select...

In this study, it was possible to evaluate the production of polyhydroxyalkanoates (PHAs) from microalgae Chlorella vulgaris and Tetradesmus obliquus, using 1% 0.25% (v/v) agro-indusytial Corn Steep Liquor residue, a product corn processing. The biomass subjected mechanical extraction 4% sodium hypochlorite + chloroform, extract further characterized Fourier Transform Infrared Spectroscopy (FTI...

It was hypothesized that differences in starch degradability account for observed differences in rumen vaccenic acid (t11-18:1) and milk rumenic acid (RA) concentrations. To test this hypothesis, starch degradability was varied through grain source and by processing. Eight Holstein cows in mid-lactation were assigned to two 4 × 4 Latin squares with four 21-day periods and four diets: dry rolled...
