Copper and zinc play important roles in many physiological processes. Dietary copper levels of 5 to 10 ppm and zinc levels of 50 to 125 ppm are generally enough to meet the pig's nutrient requirement for these processes. However, when supplied at high concentrations (100 to 250 ppm for copper and 2000 to 3000 ppm for zinc), these two minerals are known to exert positive influences on growth rate. In addition, copper is efficacious even when antibiotics also are included in the diets.2 This suggests that the response to copper is additive to the response to antimicrobials. Response to high …

Kansas Agricultural Experiment Station Research Reports

Maximizing utilization of native rangeland is an important aspect of the cow/calf phase of beef production. Native rangeland is often of poor quality (less than 7% crude protein). Protein content of the rangeland is important because nitrogen is a key growth factor used by ruminal microbes. Without adequate nitrogen, the ruminal ecosystem will not operate at peak efficiency, which subsequently reduces the supply of nutrients to the animal. Historically, producers have provided supplemental nutrients to their cattle to achieve maximum performance. Both supplemental protein and energy have been provided to cattle consuming low-quality forage with varying levels of success. Typically, …

Effects Of Feeding Low Levels Of Crude Glycerin With Or Without Other By-Products On Performance And Carcass Characteristics Of Feedlot Heifers, C.J. Schneider, G.L. Parsons, K.A. Miller, L.K. Thompson, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Expansion of the renewable fuels industries has increased availability of by-products that are well suited for use as cattle feed. Glycerin is among the principal by-products of biodiesel production, comprising approximately 10% (by weight) of the soybean oil that is used to manufacture soy-based diesel fuel. Our previous research evaluated effects of including between 0% and 16% glycerin in flaked-corn finishing diets and revealed that optimal growth performance was achieved with 2% glycerin addition. Our laboratory experiments have suggested that even lower levels of glycerin may be effective at stimulating digestion. Therefore, the objective of this study was to evaluate …

Length Of Weaning Period But Not Timing Of Vaccination Affects Feedlot Receiving Performance And Health Of Fall-Weaned, Ranch-Direct Beef Calves, M.J. Macek, J.W. Iliff, Todd W. Schmidt, L.A. Pacheco, K. C. Olson, John R. Jaeger, Daniel U. Thomson

Kansas Agricultural Experiment Station Research Reports

Weaning and preconditioning programs are thought to be crucial to calf health and performance during the finishing period. The stress of maternal separation, changes in diet, environmental changes, and exposure to unfamiliar pathogens increase susceptibility of recently weaned calves to bovine respiratory disease. Vaccination programs are implemented near weaning to decrease the incidence of respiratory disease. Many vaccination strategies are practiced by cow-calf producers in the United States. The most cautious strategy involves vaccination against respiratory disease pathogens 2 to 4 weeks before maternal separation followed by a booster at weaning. This strategy is used in instances in which time, …

Feed-Based Metaphylaxis Programs Did Not Affect Health Or Performance Of High-Risk Calves Mass Medicated With Draxxin On Arrival, M.P. Epp, R. Derstein, Dale A. Blasi Jan 2010

Feed-Based Metaphylaxis Programs Did Not Affect Health Or Performance Of High-Risk Calves Mass Medicated With Draxxin On Arrival, M.P. Epp, R. Derstein, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Bovine respiratory disease continues to be the most costly disease affecting productivity and profitability in the stocker segment. Despite their high cost, longer-acting, injectable therapeutic antimicrobials such as Draxxin (Tulathromycin; Pfizer Animal Health, New York, NY) can extend the window of treatment duration, thereby reducing the incidence and severity of bovine respiratory disease. Use of feed-based metaphylaxis programs, such as therapeutic administration of multiple 5-day pulses of Aureomycin (αrma, Inc., Bridgewater, NJ), in conjunction with an injectable metaphylaxis program may be a cost-effective way to improve bovine respiratory disease therapy without having to physically handle and stress cattle.

Wheat Gluten Films Prepared At High Temperature And Low Ph Decrease Degradation By Rumen Microorganisms, K. Blaine, James S. Drouillard Jan 2010

Wheat Gluten Films Prepared At High Temperature And Low Ph Decrease Degradation By Rumen Microorganisms, K. Blaine, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Encapsulated amino acids, vitamins, and other nutrients are gaining popularity in the ruminant feed industry. The purpose of encapsulation is to provide protection from premature digestion in the rumen, making it possible to increase bioavailability of the core ingredient in the small intestine. Encapsulated products are more effective at delivering a targeted amount of a limiting nutrient than the traditional methods of heat or chemically treating protein, which result in an excess supply of other nutrients. The main limitation of feeding encapsulated products is cost. These products are expensive because of the cost of the film forming/encapsulating materials used. Wheat …
