Four crossbred steers (395 kg) with cannulas in the rumen, proximal duodenum and distal ileum were used to evaluate effects of steaming time of corn on characteristics of digestion. The basal diet contained (DM basis) 12% forage-and 75% corn. The corn portion of the diet was provided as either dry-rolled (DR) or steam-flaked (SF), which had been exposed to steam for 34, 47 or 67 min prior to flaking to a mean density of .34 kg/liter. Longer steaming times linearly increased in vitro reactivity…

Influence of flake density on the feeding value of steam-processed corn in diets for lactating cows.
TLDR
Steam flaking improved the feeding value of corn for lactating cows by improving diet acceptability and digestibility of lipid, starch, and N and was offset by decreased (linear and quadratic components, P < .05) ADF digestibility.
Effect of corn processing on starch digestion and bacterial crude protein flow in finishing cattle.
Six ruminally and duodenally cannulated yearling steers (523 kg) were used in a replicated 3 x 3 Latin square design experiment to study the effects of corn processing on nutrient digestion,…
Comparative ruminal and total tract digestion of a finishing diet containing fresh vs air-dry steam-flaked corn.
TLDR
It is concluded that the characteristics of digestion and the feeding value of steam-flaked corn is not altered by air drying before feeding and that the initial rate of fermentation may have been greater with SFC-F.
Comparative feeding value of steam-flaked corn and sorghum in finishing diets supplemented with or without sodium bicarbonate.

TLDR
Differences in total tract starch digestibility were small and cannot explain the higher feeding value of SFC; the low ruminal degradation of sorghum N should be considered in diet formulation to avoid a deficit in ruminally available N.
Interaction of feed intake level on comparative ruminal and total tract digestion of dry-rolled and steam-flaked corn.
TLDR
It is concluded that corn processing is the primary factor influencing site and extent of starch digestion and decreasing DMI increases DE value of the diet; however, ME value is not affected because of increased energy loss as methane.
Response of lactating dairy cows to degree of steam‐flaked barley grain in low‐forage diets
TLDR
The results indicated the limited effects of processing method (grinding vs. steam flaking) and densities of SFB on cows' performance and feed utilization for dairy cows fed low-forage diets could be recommended under current feeding conditions of dairy cows.
Steam-processed corn and sorghum grain flaked at different densities alter ruminal, small intestinal, and total tract digestibility of starch by steers.
TLDR
Crossbred steers fitted with T-type cannulas in the duodenum and ileum were used to examine the effects of processing method, dry-rolled vs. steam-flaked sorghum grain, and degree of processing on site and extent of DM, starch, and N digestibilities and to measure extent of microbial N flow to theduodenum.
Influence of zeolite (clinoptilolite) supplementation on characteristics of digestion and ruminal fermentation of steers fed a steam-flaked corn-based finishing diet
Four Holstein steers (328 ± 14 kg) with ruminal and duodenal cannulas were used in a 4 × 4 Latin square design to examine the effect of level of zeolite supplementation (0, 10, 20 or 30 g…
Invited review: summary of steam-flaking corn or sorghum grain for lactating dairy cows.
TLDR
Nineteen lactation trials (43 grain processing comparisons) are summarized, in addition to digestibility and postabsorptive metabolism studies, and based on lactational performance, steam-flaked sorghum grain is of equal value to steam- Flaked corn, and steam-Flaked corn is superior to steam -rolled corn.
Effects of distillers grains with high sulfur concentration on ruminal fermentation and digestibility of finishing diets.
Twelve ruminally cannulated crossbred Angus steers were used to evaluate ruminal fermentation characteristics and diet digestibility when 30% (DM) corn dried distillers grains with solubles (DDGS)…

Influence of steam-flaked, steamed-whole or whole shelled corn on performance and digestion in beef steers.
TLDR
Three trials were conducted to evaluate finishing diets containing 67% steam-flaked corn, steamed-whole corn (SWC) or whole corn (WC), and there were no differences in nitrogen (N) intake or fecal N among the three diets.

Two trials were conducted to characterize the differences in utilization of dry-rolled and steam-flaked corn in a growing-finishing diet for feedlot cattle supplemented with and without ionophores.…
Grain processing effects on starch utilization by ruminants.
TLDR
Processing and grain source studies both suggest that maximal total tract starch digestibility is positively related to the extent of digestion in the rumen, and efficiency of ruminal starch fermentation by cattle appears to be improved by proper processing of corn and sorghum grain.
