Effects of supplementing beef cows grazing forages with wheat-based dried distillers’ grains with solubles on animal performance, forage intake & rumen metabolism
… grains with solubles (DDGS) on cow performance, forage utilization, and production costs. In the first two experiments, 48 dry, pregnant Black Angus cows (mean BW±SD; 598.2±4.2 kg) stratified by body weight (BW) and days pregnant were allocated randomly to one of three replicated (n=2) …

Application of Fecal Near Infrared Reflectance Spectroscopy and N-Alkane Labeled Supplementation Techniques to Predict Voluntary Intake in Beef Cattle
… method for the prediction of voluntary intake in beef cattle for the identification of animals divergent in feed efficiency. Additionally, the use of fecal NIRS profiling technology was evaluated for the prediction of diet characteristics. To examine the use of fecal NIRS profiling to …

Digestibility, intake and selectivity of three mixed-forage pastures by cattle
… to determine the relative value of three mixed-forage pastures, alfalfa-orchardgrass, bluegrass-white clover, and fescue-red clover. Three steers, three heifers and one esophageally cannulated steer were randomly assigned to each pasture treatment. Chemical composition, digestibility, voluntary …

Evaluation of intake and feed efficiency measures in beef cattle
Four experiments were conducted to evaluate intake and measures of feed efficiency in beef cattle. In Exp. 1 and 2, measures of feed efficiency were calculated on Angus and SimAngus heifers (Exp.1; n = 623, and Exp. 2; 404); and heifers were classified as either high, medium, or low residual feed …

Intake, digestion site, extent of digestion and digesta kinetics in grazing lactating cows
… therefore, was to investigate ruminal turnover, intake and site and extent of nutrient digestion in grazing lactating cows. Four dual cannulated (rumen and proximal duodenum) cows were randomly assigned to two groups to graze permanent pasture with no supplement or with 6.4 kg/d corn-mineral mix …

The Virginia Beef Cattle Simulation Model: A bio-economic simulation program modeling the interactions among reproduction, forage availability, nutrition, growth, and marketing in beef cattle
… Its five source-code modules are reproduction, forage, nutrition, marketing, and a tool that randomly assigns values to variables from appropriate statistical distributions. The VBCSM contains production statistics for 12 breeds, 21 forage species, and three Virginia agro-ecological zones. It …

Environmental, Biochemical, and Dietary Factors that Influence Rumen Development in Dairy Calves
… of feed, housing) to animal performance (e.g., intake of milk replacer (MR), starter, and forage; average daily gain (ADG); and feed efficiency). We looked at four different relationships to further investigate the connections between rumen, non-rumen, and performance factors. In the first and …

Urea supplementation in rumen and post-rumen for cattle fed a low-quality tropical forage
… or infusion of urea in rumen and/or abomasum on forage digestion, nitrogen (N) metabolism, urea kinetics and urea transporters in heifers fed a low-quality tropical forage. Five heifers (283±23 kg, Body Weight, BW) were fitted with rumen and abomasum fistulas and assigned to a 5 ×5 Latin square …
