Influence of Protein Supplementation on the Feeding Value of Dry Rolled and Steam-Flaked Corn in Diets for Feedlot Cattle
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%),...
متن کاملDairy Day 1995 INCLUSION OF FAT IN DIETS FOR EARLY LACTATING HOLSTEIN COWS
Twenty-four Holstein cows were used to study the effect of dietary fat on milk production and metabolic traits. Whole cottonseed and tallow were used as fat sources and substituted into the control diet on an isocaloric basis. Chopped alfalfa hay and grain sorghum silage constituted the forage in all diets. Treatments were balanced for parity, body weight, and previous lactation milk production...
متن کاملYeast in Dairy Cattle Diets
Yeast is a unicellular fungi that does not reproduce via asexual spore production (Phaff, 1966). The most commonly fed yeast in dairy diets is Saccharomyces cerevisiae (SC); a facultative anaerobic yeast often referred to as brewers or bakers yeast. The most common yeast products fed to ruminants are live cells or yeast culture mixtures. A yeast culture is a yeast-fermented product that contain...
متن کاملDry-rolled or steam-flaked grain-based diets and fecal shedding of Escherichia coli O157 in feedlot cattle.
Hindgut is a major colonization site for Escherichia coli O157 in cattle. In this study, diets were formulated to effect changes in hindgut fermentation to test our hypothesis that changes in the hindgut ecosystem could have an impact on fecal shedding of E. coli O157. Feedlot heifers (n = 347) were prescreened for the prevalence of E. coli O157 by fecal and rectoanal mucosal swab cultures. A s...
متن کاملInfluence of dietary urea level on digestive function and growth performance of cattle fed steam-flaked barley-based finishing diets.
Four Holstein steers (282 kg) with cannulas in the rumen and proximal duodenum were used in a 4 x 4 Latin square experiment to evaluate the influence of dietary urea level (0, 0.4, 0.8, and 1.2%, DM basis) in a steam-flaked barley-based finishing diet on digestive function. There were no treatment effects (P > 0.20) on ruminal digestion of OM and ADF. Increasing dietary urea level increased (li...
