Grains are fed to livestock primarily to supply energy, and the major energy source in cereal grains is starch. For maximum starch digestion, corn and sorghum grain must be processed. For non-ruminants, starch from finely ground grain is fully digested, but for ruminants fed concentrate diets, finely ground grain can cause metabolic diseases. Hence, steam rolling or flaking and fermentation (hi...

Starch particle size characteristics of 81 diverse corn silage samples, which included 27 combinations of hybrid, planting dates, and harvest dates subjected to 3 different degrees of kernel processing, were determined via vertical shaking through 9 screens with nominal square apertures of 19.0, 13.2, 9.5, 6.7, 4.75, 3.35, 2.36, 1.18, and 0.6 mm and a pan. Starch content of dry matter remaining...

Corn starch particles are used as a surgical glove lubricant. At present there is no better alternative for this lubricant. Implantation of corn starch particles into the peritoneal cavity can induce foreign body reactions, starch peritonitis and starch granulomata, and may cause adhesions and intestinal obstruction. Starch peritonitis should be treated conservatively.

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...

Flint corn has a greater proportion of vitreous endosperm than dent corn (Philippeau et al, 1999). Philippeau and Michalet-Doureau (1997) observed that increased kernel vitreousness was associated with decreased ruminal starch degradation. Increased kernel vitreousness may explain the reduction in total-tract starch digestibility observed for mature whole-plant corn silage (WPCS; Bal et al., 19...

A study has been made of the compaction properties of two experimental starches, namely yam starch obtained from Dioscorea rotundata and rice starch obtained from Oryza sativa and the mechanical properties of their tablets, in comparison with those of official corn starch. The influences of the physical and geometric properties of the starch particles on the compression properties of the starch...

Eighty medium-framed yearling crossbreed heifers (357 kg) were used in a 110-d trial to evaluate the influence of dietary protein level (11 vs 14%) on the feeding value of dry rolled (DRC) and steam-flaked corn (SFC). All diets contained 1% urea, cottonseed meal (CSM) was the source of supplemental UIP. Steam flaking corn reduced DMI (9%, P < .10), and increased (P < .01) feed efficiency (14%),...

This study was conducted to evaluate the effects of infrared irradiation for 60, 90, 120 and 150 seconds on starch degradability and chemical compositions of corn grains. Three ruminally fistulated rams were used to measure in sacco degradation. There was a linear increase in DM of irradiated corn grains (P<0.001). Infrared irradiation decreased potentially degradable fraction and constant degr...

Cereal Chem. 76(1):96-99 A corn wet-milling process in which alkali was used was studied as an alternative to the conventional corn wet-milling procedure. In the alkali wet-milling process, corn was soaked in 2% NaOH at 85°C for 5 min and then debranned mechanically to obtain pericarp as a coproduct. Debranned corn was cracked in a roller mill, and the cracked corn was steeped with agitation fo...

Compared with floury or high-moisture corns, dry corn with a greater percentage of vitreous endosperm has been demonstrated to be negatively related to starch digestibility and milk yield of lactating dairy cows. Starch granules in corn are encapsulated by hydrophobic prolamin proteins that are innately insoluble in the rumen environment. Corn prolamin proteins are named zein, and laboratory me...
