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 ...

Packaging Systems And Storage Times Serve As Post-Lethality Treatments For Listeria Monocytogenes On Whole Muscle Beef Jerky, A. Lobaton-Sulabo, T. Axman, Kelly J.K. Getty, Elizabeth A.E. Boyle, N. Harper, K. Uppal, B. Barry, James J. Higgins

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 on shelf-stable ...


Effects Of Wet Corn Gluten Feed And Dietary Particle Size On Ruminal Fermentation And Milk Production, M.L. Sullivan, Barry J. Bradford 2010 Kansas State University Libraries

Effects Of Wet Corn Gluten Feed And Dietary Particle Size On Ruminal Fermentation And Milk Production, M.L. Sullivan, Barry J. Bradford

Kansas Agricultural Experiment Station Research Reports

Wet corn gluten feed (WCGF) was included in 4 diets at 0, 11, 23, and 34% of diet dry matter. Alfalfa hay was used to maintain at least 10% of particles ≥0.71 inches in length (the top screen of the Penn State Particle Separator) in all diets. Ruminal probes were placed in the rumens of 7 ruminally cannulated lactating Holstein dairy cows to measure ruminal pH. As WCGF increased in the diet, dry matter intake and milk production increased quadratically with 23% WCGF supporting the highest feed intake and milk yield. Ruminal pH and milk fat content were similar ...

Lysine Degradation By Ruminal Fusobacterium Necrophorum, E.A. Elwakeel, R.G. Amachawadi, A.M. Nour, M.E. Nassar

Kansas Agricultural Experiment Station Research Reports

Three experiments were conducted to characterize lysine fermentation by Fusobacterium necrophorum, a ruminal bacterium that is known to degrade amino acids. In Experiment 1, 7 strains of Fusobacterium necrophorum were inoculated into media containing lysine (50 mM), lactate (50 mM), or lysine plus lactate (50 mM each) as the major energy substrate to evaluate growth and ammonia production. All strains grew with lysine, lactate, or lactate plus lysine as the primary substrate. When grown with lysine, all strains produced ammonia as an end product, even if lactate was also present. Smaller concentrations of ammonia for medium containing lactate plus lysine ...

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

Under the conditions of modern swine production, pigs need to be fed a balanced diet that meets their daily nutritional requirement for maintenance, growth, and reproduction. However, nutrient intake is largely determined by voluntary feed intake, which is greatly influenced by the chemical senses of olfaction and taste. Thus, it is essential to make sure that diets being offered to pigs are highly palatable to ensure high feed intake. This is especially important during times when pigs have decreased appetite, such as the first few days post weaning. Therefore, it is believed that enhancement of taste or smell through the ...


Feed Additives For Swine: Fact Sheets – High Dietary Levels Of Copper And Zinc For Young Pigs, And Phytase, J Y. Jacela, Joel M. DeRouchey, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, David G. Renter, Steven S. Dritz 2010 Kansas State University Libraries

Feed Additives For Swine: Fact Sheets – High Dietary Levels Of Copper And Zinc For Young Pigs, And Phytase, J Y. Jacela, Joel M. Derouchey, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, David G. Renter, Steven S. Dritz

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 ...

Effects Of Feeder Design And Feeder Adjustment On The Growth Performance Of Growing- Finishing Pigs, J R. Bergstrom, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

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 ...

The Effects Of Feeder Space And Adjustment On Growth Performance Of Finishing Pigs, A J. Myers, J R. Bergstrom, Robert D. Goodband, Michael D. Tokach, Joel M. Derouchey, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 288 pigs (PIC TR4 x 1050, initially 82 lb) were used in a 91-d study to evaluate the effects of feeder trough space (1.75 vs. 3.5 in/pig) and minimum feeder-gap opening of 0.5 in. (narrow), vs. 1.0 in. (wide) on finisher pig performance. Our hypothesis was that at minimal feeder trough space (1.75 in./pig), feeders should be set at a wide gap opening to avoid limiting feed intake and ADG. The feeders were adjusted to the minimum gap setting, but the agitation plate could be moved upward to a maximum ...

Effects On Bacon Quality Of Feeding Increasing Glycerol And Dried Distillers Grains With Solubles To Finishing Pigs, B L. Goehring, Terry A. Houser, Joel M. Derouchey, Melvin C. Hunt, Michael D. Tokach, Steven S. Dritz, B M. Gerlach, Robert D. Goodband, Jim L. Nelssen, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

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
