Flaking corn: processing mechanics, quality standards, and impacts on energy availability and performance of feedlot cattle.
Based on performance of feedlot cattle, steam flaking increases the value of corn by 18%, considerably more than is suggested by tabular values. Tabular values underestimate the energy availability of flaked corn by failing to account for digestibility of the nonstarch OM that is increased by flaking by the same magnitude (10%) as starch. Correcting for improvement in digestibility of nonstarch...
متن کاملEstimating starch availability and protein degradation of steam-flaked and reconstituted sorghum grain through a gas production technique.
Five steam-flaked sorghum grain (SFSG) samples with bulk densities of 476, 412, 347, 309 and 283 g/liter made by adjusting tension between mill rollers and three reconstituted sorghum grain (RSG) samples with reconstitution times of 10, 20 and 30 d and a control sample were analyzed for gas production kinetics (rumen liquor fermentation) and enzymatic glucose release (amyloglucosidase). Protein...
متن کاملInfluence of Processing of Barley Grain on Characteristics of Digestion, Ruminal Fermentation and Digestible Energy of Diet inLactating Cows
A digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. The experiment consisted in 4 periods and lasted 84 days. The total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...
