Effects of feeding moderate-energy high-forage diets with reduced DCAD for twenty-one or forty-two days prepartum on mineral homeostasis and postpartum performance
… while providing protection against hypocalcemia. High-fiber prepartum diets including wheat straw are inherently low in potassium and have been shown to reduce risk of hypocalcemia. Few studies examine effects of inclusion of DCAD lowering feed additives in low-potassium dry cow diets. The …

Diurnal Variation Patterns in the Rumen of Cattle: Studies of Bacterial Numbers, Carbohydrate-Specific Groups and Ruminal Fluid Parameters
… rumen bacterial populations in cattle fed either high forage or high concentrate diets (maintenance intake levels) was followed after a once daily feeding. Samples of ruminal contents were collected from rumen-fistulated, Holstein steers at -1, +2, 4, 8, 12 and 16 h after feeding. The bacterial …

Effects of Maturity at Harvest of Triticale and Dietary Forage Inclusion on Production Performance, Nutrient Utilization, and Milk Fatty Acid Profile of Lactating Dairy Cows
… and that the difference would be greater in high-forage diets. A single field of triticale was planted, and harvested at the BS or SDS of maturity, and the harvested forage was ensiled in separate bunker silos. Eight primiparous and 16 multiparous Holstein cows were assigned to 1 of 4 diets …

Improving Feed Efficiency Through Forage Strategies for Increasing Dairy Profitability and Sustainability
… to improving feed efficiency through various forage utilization strategies with or without the inclusion of various supplemented products. The first study evaluated the supplementation of a cobalt-lactate product and its effects on fiber digestibility and milk production parameters when fed to …

Strategies to Decrease Incidence of Fatty Liver in Dairy Cows
… (30 primiparous) were fed controlled-energy, high-forage (CEHF) diets or were overfed energy (OVERFED) from dry-off to parturition, or CEHF for the first 40 d after dry-off, followed by OVERFED for the last approximately 20 d before parturition (2-stage). During the periparturient period, cows …

Influence of dietary component manipulation and feed management strategies on growth and rumen development of weaned dairy heifers
… rumen development of calves fed conventional or high planes of nutrition pre-weaning; therefore, we evaluated two milk replacer feeding programs with two post-weaning diets differing in non-fiber carbohydrate (NFC) content. Overall, calves fed a high plane of nutrition pre-weaning with a low NFC …

Digesta Passage, Fermentation, and Microbes in the Hindgut and Its Relative Contribution to the Nutrition of Cattle
… the cecum and colon was greatly affected by the forage to concentrate ratio; physical form of the forage had little effect. Contribution of the cecum and colon to total tract digestion of nutrients was greatest with the high grain diets. With the high grain diets, the cecum and colon accounted …

Soybean Meal Substitution with a Microbial Protein Source in Dairy Cow Diets
… matter intake, rumen, and blood parameters of high producing dairy cows. Sixteen Holstein cows (twelve multiparous and four primiparous) with 93 ± 37 DIM were used in a 4 x 4 Latin square design with four 28 d periods. Cows were blocked by parity and production, with one square consisting of 4 …

Barley growth, physiology, and forage quality as influenced by defoliation and water stress
… L.) after defoliation and their effects on forage-quality characteristics is needed. The objectives of this study were to investigate defoliation and water deficit stress effects on regrowth, physiology and forage quality characteristics of four barley cultivars known to differ in response …

Understanding the mechanism of salt tolerance in alfalfa (Medicago sativa L.)
… (Medicago sativa L.) is an important perennial forage legume characterized by its wide adaptability, high forage yield, good quality, and resistance to frequent cuttings. It is often used for pasture, hay, silage, dehydrated products, seed production, and soil improvement. Alfalfa is moderately …

Effects of Phosphorus Supplementation on Grazing Beef Cattle
… mineral tags, producer surveys, and fecal, forage, and soil samples were collected from beef cattle operations in Virginia's Chesapeake Bay watershed. Samples (n=166) were collected from 120 producers in 11 counties. Soil test P results were based on Virginia Cooperative Extension soil test …

The Relationships Between the Ruminal Digestibility Kinetics of Fiber, Total-Tract Nutrient Digestibility, and Methane Emissions from Lactating Dairy Cattle
… detergent fiber (NDF), are influenced by both forage quality and dietary composition. This dissertation examined how forage type, maturity, and dietary inclusion level affect nutrient digestibility, fiber passage dynamics, milk production, and CH4 emissions in high-producing dairy cows. Chapter …

Manure and Nutrient Accretion, Partitioning, and Excretion in Holstein Heifers
… the fact that feeding programs for heifers are highly variable from region to region and even from farm to farm indicated the need to examine the effects of diet on nutrient utilization. Therefore, the objective of this work was to evaluate how differences in levels of dietary protein and energy …
