Two experiments were performed to evaluate the effects of feeder design (conventional dry feeder vs. wet-dry feeder) and adjustment on growing-finishing pig performance. In both experiments, all pigs (PIC 337 x 1050) were fed the same corn-soybean meal diets with 15% dried distillers grains with solubles (DDGS). In Exp. 1, 1,296 pigs (initially 43 lb) were used in a 69-d study. From d 0 to 27, 3 feeder settings were evaluated for each feeder type. Numbered settings (located in each feeder) were 6, 8, and 10 for the conventional dry feeder and 6, 10, and 14 for the wet-dry feeder. …

A total of 84 barrows (PIC 337 x 1050, initially 68.3 lb) were fed a corn-soybean meal-based diet with added dried distillers grains with solubles (DDGS; 0 or 20%) and increasing glycerol (0, 2.5, or 5%) to determine the effects on belly quality. Criteria that were evaluated included: belly length, thickness, firmness, and slice yield; proximate and fatty acid analyses; iodine values; and sensory characteristics. There were no (P>0.08) DDGS x glycerol interactions on any criteria measured. Inclusion of 20% DDGS in the diet decreased belly firmness (P<0.04), as measured by the belly flop test (fat-side down method). Twenty percent DDGS decreased (P<0.01) the percentage of myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, vaccenic acid, total saturated fatty acids, and total monounsaturated fatty acids. In contrast, 20% DDGS increased (P<0.01) the percentage of linoleic acid, α-linolenic acid, eicosadienoic acid, total polyunsaturated fatty acids, unsaturated:saturated fatty acid ratios, polyunsaturated:saturated fatty acid ratios, and iodine values. The inclusion of 0, 2.5, and 5% glycerol in swine diets did not affect any measured criteria in this study. In conclusion, feeding DDGS at a level of 20% decreased belly firmness and changed the fatty acid profile; however, it did not affect belly processing or sensory characteristics. Glycerol fed at 2.5 or 5.0% did not affect belly quality, fatty acid profile, or sensory characteristics of bacon.; Swine Day, Manhattan, KS, November 18, 2010

Round Bale Alfalfa Processing Method Does Not Influence Feeding Or Mixing Characteristics In A Total Mixed Ration, S.Q. Jones, T.T. Marston, T.J. Kraus, Joel M. Derouchey, Justin W. Waggoner, Ryan M. Breiner
Kansas Agricultural Experiment Station Research Reports
Nutritionists and producers often assume that ingredients in a total mixed ration are uniformly mixed. However, many factors may affect ration homogeneity, including particle size, shape, and density and mixer discharge location. Forages are often ground prior to mixing in a total mixed ration to reduce variation in forage particle length. However, preprocessing forages while baling may facilitate particle length reduction and eliminate the need to grind forages prior to mixing. Objectives of this study were to determine the effects of forage processing method on uniformity and particle length of the total mixed ration at different discharge locations throughout mixing.
Beta Acid Extracts Of Hops Have A Modest Effect On Ruminal Metabolism And Apparent Total Tract Digestibility By Steers Fed High-Concentrate Diets, S. Uwituze, J.M. Heidenreich, James J. Higgins, James S. Drouillard
Beta Acid Extracts Of Hops Have A Modest Effect On Ruminal Metabolism And Apparent Total Tract Digestibility By Steers Fed High-Concentrate Diets, S. Uwituze, J.M. Heidenreich, James J. Higgins, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Hops have been used for centuries to control bacterial contamination in beer production. Today, α acids are extracted from hops for use in flavoring beer, leaving residues that are rich in beta acids. Beta acid fractions of hops can selectively inhibit specific ruminal Gram-positive bacteria that are responsible for major digestive disturbances, such as acidosis and bloat, and have a chemical structure similar to that of ionophores used in feedlot production. Use of ionophores improves efficiency of feed utilization and decreases the incidence of digestive disturbances that are a major cause of morbidity and mortality in cattle feeding operations. The …

Round Bale Alfalfa Processing Method Affects Heifer Growth But Does Not Influence Wastage Or Eating Preference, S.Q. Jones, T.T. Marston, T.J. Kraus, Joel M. Derouchey, Justin W. Waggoner, Ryan M. Breiner
Kansas Agricultural Experiment Station Research Reports
Many factors affect forage quality, including moisture level at baling, compaction, bulk density, and maturity at harvest. Losses of dry matter and nutrient value occur during field curing. Hay baled at or above 18% moisture should have less nutrient loss in the field. However, hay baled at these moisture levels has the potential to heat during storage, causing dry matter loss and nutrient degradation. Also, as particle length of forage decreases, packing ability of forage and bulk density of bales increase. Although particle length is reduced by grinding baled forage, this can result in nutrient losses. Also, when cattle are …

Botanical Composition Of Diets Grazed By Beef Cows In The Kansas Flint Hills During Winter, G.J. Eckerle, K. C. Olson, Walter H. Fick, L.A. Pacheco, John R. Jaeger
Kansas Agricultural Experiment Station Research Reports
Analysis of microscopic plant fragments recovered from the gut of wild herbivores (i.e., microhistological analysis) has been used to estimate diet composition, but there is debate as to whether microhistological analysis of fecal samples is an appropriate method for characterizing diets of grazing beef cattle. Therefore, our goal was to determine whether this approach could effectively quantify the botanical composition of diets grazed by mature beef cows in the Kansas Flint Hills during winter.
Effects Of Smartlic Hi-Pro 40 Block Supplements On Ruminal Microbes In Cattle Fed Low-Quality Forages, K.D. Derstein, James S. Drouillard
Effects Of Smartlic Hi-Pro 40 Block Supplements On Ruminal Microbes In Cattle Fed Low-Quality Forages, K.D. Derstein, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Dormant pastures and native grass hays often are deficient in protein and other nutrients needed to support optimum performance of beef cattle. These nutrients are essential for maintaining viable populations of symbiotic rumen microorganisms that digest the fiber in forages. When nutrient deficiencies occur, microbial populations in the rumen decrease, thereby limiting digestion of low-quality forages. This study was conducted to evaluate changes in rumen microbial populations and digestive activity when cattle consuming low-protein native grass hay are given access to high-protein, free-choice block supplements.

Using a growth promotant at the correct time of finishing is critical for maximizing profit potential. Previous studies have shown that zilpaterol-HCl (Zilmax; Intervet/ Schering-Plough Animal Health, Millsboro, DE) improves carcass characteristics. The objective of this study was to determine effects of prior body composition on subsequent changes in carcass weight, fatness, and muscle in heifers fed Zilmax so producers can introduce Zilmax at the level of finish that will result in the most desirable response. We hypothesized that fatter heifers use fat as the fuel for muscle growth.

Zilpaterol-HCl (Zilmax; Intervet/Schering-Plough Animal Health, Millsboro; DE) is an orally active β2-adrenergic agonist that is approved for use in feedlot cattle at the rate of 7.56 g/ton of diet dry matter for the final 20 to 40 days on feed. The minimum withdrawal time for Zilmax is 3 days. Zilmax increases hot carcass weight and dressing percentage, primarily as a result of increasing lean muscle mass and decreasing body fat. Zilmax also decreases marbling and increases shear-force values (i.e., less tender) of steaks. This study was conducted to determine whether the benefits of Zilmax would be retained with longer withdrawal …

Supplementing Fructose-Based Block Supplements To Forage-Fed Cattle Increases Capacity For Lactic Acid Metabolism, K.A. Miller, M.J. Quinn, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Acidosis is one of the more important maladies afflicting cattle fed significant amounts of grain and has enormous economic impact for feedlots, dairies, and producers of seed stock. The highest incidence of acidosis occurs when animals are being transitioned from high-roughage diets to diets containing high levels of concentrates. When grain-based diets are consumed in excess, consumed too quickly, or fed without proper adaptation, digestive end products (organic acids) can accumulate within the rumen, resulting in acidosis. Lactic acid is one of the key organic compounds that accumulates under these conditions. Coupled with the animal's limited ability to metabolize lactate, …

Kansas Agricultural Experiment Station Research Reports
Expansion of the biodiesel industry has increased supplies of crude glycerin available for livestock feeding. Catalyzed reactions between methanol and triglycerides from vegetable oils, such as soybean oil, yield biodiesel and a coproduct, crude glycerin. Approximately 10% of the weight of soybean oil used to produce biodiesel becomes glycerin. Limited work has been conducted to understand metabolism of glycerin in ruminant livestock. In previous studies at Kansas State University, feeding crude glycerin at 8% or less of the diet improved cattle performance. Subsequent laboratory experiments indicated that low levels of glycerin may improve ruminal fermentation. This study was conducted to …

Increased Concentrations Of Bovine Intestinal Mucus Encourage Growth Of Escherichia Coli O157:H7, J. Heidenreich, C. Aperce, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Cattle have been implicated as carriers of the human pathogen Escherichia coli O157:H7. Contamination of the beef supply by E. coli O157 can occur during harvest and processing, causing costly recalls or human illness. Many interventions have been applied in attempts to prevent contamination of carcasses in processing plants, such as development of HACCP procedures, carcass washes, and steam pasteurization, but contaminations still occur. Mechanisms that allow E. coli O157:H7 to thrive in cattle at sporadic times and in such large numbers are poorly understood. Understanding factors that stimulate E. coli O157 growth in cattle will aid in identifying effective …

Bovine respiratory disease continues to be the most costly disease affecting productivity and profitability in the stocker segment. Long-acting injectable antimicrobials are presently used to reduce the incidence and severity of bovine respiratory disease. However, future use of antimicrobial treatment may be significantly curtailed in light of an increasing negative perception of antibiotic usage in food animals by consumers and governmental agencies. Consequently, preconditioning and enhanced nutrition programs that may include nutraceuticals could become more prevalent. MorindaMax (Morinda International, Provo, UT) is a natural product manufactured from the Morinda citrifolia fruit (i.e., Noni). Published literature suggests this plant extract has …

Kansas Agricultural Experiment Station Research Reports
Following several outbreaks involving Listeria monocytogenes in ready-to-eat meat and poultry products, the United States Department of Agriculture Food Safety and Inspection Service required that processors of these products implement post-processing intervention strategies for controlling L. monocytogenes. The USDA defines a postlethality treatment as a process that reduces L. monocytogenes by at least 1 log. Research has shown that packaging can generate a 1 log L. monocytogenes reduction following 1 or more weeks of storage at room temperature. The objective of our study was to determine the effect of packaging system and storage time on reducing L. monocytogenes in shelf-stable …

Kansas Agricultural Experiment Station Research Reports
There is increasing pressure for livestock producers to minimize the use of antibiotics as growth promoters in food animals. Supplementing beneficial microorganisms in the gastrointestinal tract is one potential alternative. A diverse population of beneficial and potentially harmful microorganisms exists in the gastrointestinal tract of the pig. In a healthy animal, a delicate balance between these two groups of organisms is maintained. However, during times of stress, such as during weaning in the case of piglets, this balance may be affected and can lead to a rapid growth of harmful microorganisms. This may result in poor performance or disease. Thus, …

Kansas Agricultural Experiment Station Research Reports
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 …
