Ectoparasites Of Bats In Mongolia (Ischnopsyllidae, Nycteribiidae, Cimicidae And Spinturnicidae), Ingo Sceffler, Dietrich Dolch, Jargalsaikhan Ariunbold, Nyamsuren Batsajchan, Andreas Abraham, Klaus Thiele

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

For large parts of the world, the knowledge of bat ectoparasites is still scanty. Regarding Mongolia, only few studies exist to date. This paper analyzes results from extensive captures between 2005-2008, carried out in different sites of Mongolia. Discussed ectoparasites include bat fleas, (Ischnopsyllidae), bat flies (Nycteribiidae), and bat bugs (Cimicidae) and spinturnicid mites (Spinturnicidae). A number of species found in this study were new records for Mongolia, and for many species additional sites were reported. For some bat species, the spectrum and frequency of larger ectoparasites could be determined for the first time.

The Effects Of Feeder Space And Adjustment On Growth Performance Of Finishing Pigs (2010), 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 gap opening of 0.75 in. or 1.25 …

Capacity Of The Bovine Intestinal Mucus And Its Components To Support Escherichia Coli O157:H7 Growth, C. Aperce, J. Heidenreich, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Escherichia coli O157:H7 contamination of human food products is a major concern for the beef industry. The pathogens responsible for outbreaks often originate from cattle, and E. coli O157:H7 can thrive in healthy cattle. To control contamination in the food chain, it is essential to understand how this pathogen is able to grow and compete with other bacteria in the gastrointestinal tracts of cattle. Previous studies have shown that bovine intestinal mucus supports bacterial colonization and can selectively influence makeup of the bacterial population. Intestinal mucus is made of mucins, which are gel-forming glycoproteins. Mucin molecules contain sialic acid that …

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, …

Long-Term Cidr Program For Synchronization Of Estrus In Beef Heifers Produces Acceptable Ai Pregnancy Rates, Sandra K. Johnson, J.W. Bolte, John R. Jaeger Jan 2010

Long-Term Cidr Program For Synchronization Of Estrus In Beef Heifers Produces Acceptable Ai Pregnancy Rates, Sandra K. Johnson, J.W. Bolte, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Routinely achieving pregnancy rates greater than 50% with fixed-time artificial insemination (AI) in heifers has been difficult. The Beef Reproduction Task Force recently added the intravaginal progesterone-releasing device (CIDR)-Select to its list of recommended fixed-time AI protocols. Research and field trials in Missouri have achieved AI pregnancy rates in the range of 55% to 60%. Another relatively new protocol is the 5-day CO-Synch, a timed AI protocol + CIDR that has produced pregnancy rates similar to or higher than those obtained with the standard 7-day CO-Synch + CIDR protocol. It is not known whether these two systems differ in terms …

Dried Distillers Grains Supplemented At Different Frequencies To Stocker Heifers Grazing Late-Season Flint Hills Native Pastures, M.P. Epp, W.L. Metzen, Brandon E. Oleen, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Wetter-than-normal summer grazing seasons can produce excessive forage beyond what the typical Flint Hills double-stock harvest rate can remove. These late-summer native grasses do not contain adequate protein to sustain economical gains for stocker cattle, but producers can extend the grazing season by using a protein-based supplement to generate economically feasible rates of gain. Use of dried distillers grains as a supplementation program can help promote overall productivity during the fall grazing season. However, the drawback is the potential high labor input for supplement delivery. Delivering supplements at reduced frequencies per week may be able to sustain daily gains of …

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 …

Effect Of Nitrogen Supplementation And Zilpaterol-Hcl On Urea Recycling In Steers Consuming Corn-Based Diets, D.W. Brake, M.L. Jones, Evan C. Titgemeyer Jan 2010

Effect Of Nitrogen Supplementation And Zilpaterol-Hcl On Urea Recycling In Steers Consuming Corn-Based Diets, D.W. Brake, M.L. Jones, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Cattle have the innate ability to recycle nitrogen absorbed post-ruminally back to the rumen as endogenously synthesized urea. Urea returning to the rumen provides an additional opportunity for ruminal microbes to benefit from nitrogen absorbed postruminally. Urea recycling may provide a significant benefit to cattle when protein requirements of ruminal microbes are high or when large amounts of the dietary protein escape ruminal degradation.

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, …

High Sulfur Content In Distillers Grains With Solubles May Be Deleterious To Beef Steer Performance And Carcass Quality, S. Uwituze, G.L. Parsons, C.J. Schneider, K.K. Karges, M.L. Gibson, Larry C. Hollis, James S. Drouillard Jan 2010

High Sulfur Content In Distillers Grains With Solubles May Be Deleterious To Beef Steer Performance And Carcass Quality, S. Uwituze, G.L. Parsons, C.J. Schneider, K.K. Karges, M.L. Gibson, Larry C. Hollis, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Distillers grains with solubles are becoming an increasingly important staple of cattle diets because of rapid expansion of the fuel ethanol industry. Sulfuric acid often is used in ethanol production processes to clean and control the pH of fermenters. Consequently, distillers grains with solubles can occasionally contain high sulfur concentrations. Within the rumen, sulfur is converted to hydrogen sulfide gas by ruminal microbes. Hydrogen sulfide is eructated from the rumen and subsequently aspirated into the lungs; excess amounts of hydrogen sulfide can cause polioencephalomalacia (brainers). Polioencephalomalacia is characterized by increased respiration, decreased feed intake, listlessness, muscular incoordination, progressive blindness, and …

Effect Of Nitrogen Supplementation On Urea Recycling In Steers Consuming Corn-Based Diets, D.W. Drake, M.L. Jones, David E. Anderson, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Nitrogen absorbed in the small intestine of cattle can be recycled to the rumen and incorporated into microbially synthesized amino acids. This is an advantage when dietary protein is low or when ruminally available nitrogen is limited by poor ruminal protein degradation. In a survey, consulting feedlot nutritionists reported that 83% of their clients used ethanol coproducts in finishing diets. Ruminal availability of nitrogen in dried distillers grains with solubles is low (i.e., 25% of total nitrogen). Thus, urea recycling may be of greater relative importance when distillers grains are used to supplement protein to cattle. The goals of our …

Kansas Agricultural Experiment Station Research Reports

Meat tenderness is the most important palatability attribute affecting consumers' overall eating experience. Injection enhancement and blade tenderization have long been used to improve this important trait. Injection enhancement has been shown to improve tenderness, juiciness, color stability, and cooking yield, but not all solutions have been adequately evaluated. Thus, there is a need to conduct research on the effectiveness of common enhancement solutions. We published results from an extensive study comparing a solution of phosphate, salt, and rosemary with a solution of calcium lactate and rosemary injected by using traditional needle injection. There were no differences in Warner-Bratzler shear …

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 …
