Soyhulls as an Alternative Feed for Lactating Dairy Cows: A Review
Journal of Dairy Science · 2003-04-01 · 179 citations
reviewOpen accessSenior authorDairy producers use soyhulls, a byproduct of soybean processing, to replace either grain or forage in diets of lactating dairy cows. In view of the nutritional and economical value of soyhulls it is anticipated that this practice will continue to increase in popularity among nutritionists and producers of ruminant animals. This paper reviews information regarding the nutritional value of soyhulls and the effects of feeding this alternative feed on ruminal fermentation, nutrient digestion and uti…

articleOpen access1st authorCorrespondingTo date, genetically enhanced plants in the marketplace that are used as feeds for livestock are based on producing insecticidal compounds or developing herbicide tolerance. Corn grain, whole plant green chop corn, corn silage, corn residue, soybeans, and soybean meal from the current genetically enhanced plants have been fed to chickens, sheep, beef cattle, and dairy cows and compared with feeds produced from isolines of nongenetically enhanced plants. Results from 23 research trials indicate t…

articleOpen accessSenior authorThree ruminally and duodenally cannulated cows were assigned to an incomplete 4 4 Latin square with four 14-d periods and were fed diets supplemented with urea, solvent soybean meal, xylosetreated soybean meal (XSBM), or corn gluten meal to study the effects of crude protein source on omasal canal flows of soluble AA. Soluble AA in omasal digesta were fractionated by ultrafiltration into soluble proteins greater than 10 kDa (10K), oligopeptides between 3 and 10 kDa (3-10K), peptides smaller than…

articleOpen accessTwo trials were conducted to evaluate effects of feeding supplemental fibrolytic enzymes or soluble sugars and malic acid on milk production. In trial 1, 257 cows at four sites were fed a basal diet consisting of no more than 60% of forage DM as corn silage and less than 40% as alfalfa hay. Cows were assigned randomly within site, parity, and two stages of lactation to: 1) control; 2) enzyme A; 3) enzyme B; and 4) soluble sugars and malic acid. There was a 14-d pretreatment and an 84-d treatment…
