Supplementing Cow-Calf Pairs Grazing Smooth Bromegrass, Jason M. Warner, Annie J. Doerr, Galen E. Erickson Erickson, Rick J. Rasby, Terry J. Klopfenstein Jan 2015

Supplementing Cow-Calf Pairs Grazing Smooth Bromegrass, Jason M. Warner, Annie J. Doerr, Galen E. Erickson Erickson, Rick J. Rasby, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A three-year study evaluated supplementing ethanol co-products mixed with low-quality forage to cow-calf pairs grazing smooth bromegrass as a method to replace grazed forage intake. Supplementing a 30:70 modified distillers grains plus solubles:cornstalks mixture reduced estimated grazed forage intake by approximately 40%. Doubling the stocking rate and supplementing did not impact cow or calf performance. A summer supplementation program designed to reduce grazed forage intake is a viable strategy for increasing stocking rate if forage for grazing is limited.

Effect Of Post-Weaning Management And Age At Weaning On Calf Growing And Finishing Performance, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

The impact of post-weaning management system and calf age at weaning on growing and finishing performance was evaluated. During the growing phase, cattle in the fast-track system had improved intake, gain, and feed conversion. Although initial finishing weight was similar between systems, slow-track cattle had greater intake, gain, final body weight, and carcass weight. While the impact of age at weaning was negligible, the improvement in finishing performance for slow-track cattle demonstrates the value of different management systems.

Estimation Of British- And Continental-Specific Heterosis Effects For Birth, Weaning, And Yearling Weight In Cattle, Lauren N. Schiermiester, R. Mark Thallman, Larry A. Kuehn Kuehn, Matthew L. Spangler

Nebraska Beef Cattle Reports

Heterosis, assumed proportional to expected breed heterozygosity, was calculated for 6,834 individuals with birth, weaning, and yearling weight records from Cycle VII of the U.S. Meat Animal Research Center Germplasm Evaluation Program. Heterosis was further estimated by proportions of British x British (BxB), British x Continental (BxC), and Continental x Continental (CxC) crosses. Estimates of BxB, BxC, and CxC heterosis were significant for weaning and yearling weight. This study illustrated that differences among biological types exist and provide an opportunity to utilize specific breeds and exploit heterosis in a crossbreeding system to achieve production goals.

Stocking Rate Effects On Forage Nutrient Composition In Early Summer Pastures, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, K. H. Jenkins, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Nebraska Sandhills upland range pastures were used to measure the effectsof stocking rate on forage nutrient content in early summer pastures. Stocked pastures had lower CP, in vitroorganic matter digestibility, forage availability, and higher NDF compared with ungrazed pastures. Clipped samples of current year growth had greater CP and in vitro organic matter digestibility than diet samples. Observed results indicate early season grazing decreasesdiet nutrient content and forage availability compared with ungrazed pastures, suggesting that cattle were consuming both current and previous year growth.

Effects Of Replacing Corn With A Pelleted Treated Corn Stover And Distillers Grains On Intake And Total Tract Digestibility Of Finishing Diets, Jana L. Harding, Melissa L. Jolly-Breithaupt, Galen E. Erickson Erickson, James C. Macdonald

Nebraska Beef Cattle Reports

A digestion study was conducted to evaluate the effects of replacing dry-rolled corn (DRC) with a pelleted feed containing treated corn stover, solubles, and distillers grains (DDG). Replacing DRC with the pelleted feed had no effect on intakes. Similarly, total tract digestibilities of DM, OM, or NDF were not affected by dietary treatment. There was a tendency for differences in average ruminalpH between treatments; however, proportions of acetate, propionate, and butyrate were not impacted. It was concluded that the DRC could be replacedwith a pelleted stover and distillers in the finishing diet without altering total tract digestion.

Correlation Of Ultrasonographic Small Intestinal Wall Layering With Histology In Normal Dogs, Alexandre Benjamin Le Roux

LSU Master's Theses

Five intestinal layers are commonly described ultrasonographically in dogs. However, current high-frequency endosonography allows the identification of 9 layers in people. The aim of this study was to describe ex vivo small intestinal layering in dogs and correlate ultrasonographic layering with histological layers. Our hypothesis was that, similar to findings in humans, discrepancies exist in thickness and visibility of intestinal layers between histology and ultrasound in dogs. Twelve adult dogs were included in the study. They were euthanized for reasons unrelated to gastrointestinal disease, but extensive medical history was unavailable. Duodenum, jejunum and ileum samples were resected immediately after euthanasia. …

Taxonomy And Molecular Epidemiology Of Echinococcus Granulosus Sensu Lato, Thomas Romig, Dennis Ebi, Marion Wassermann Jan 2015

Taxonomy And Molecular Epidemiology Of Echinococcus Granulosus Sensu Lato, Thomas Romig, Dennis Ebi, Marion Wassermann

Harold W. Manter Laboratory of Parasitology: Library Materials

Echinococcus granulosus, formerly regarded as a single species with a high genotypic and phenotypic diversity, is now recognized as an assemblage of cryptic species, which differ considerably in morphology, development, host specificity (including infectivity/pathogenicity for humans) and other aspects. This diversity is reflected in the mitochondrial and nuclear genomes and has led to the construction of phylogenetic trees and hypotheses on the origin and geographic dispersal of various taxa. Based on phenotypic characters and gene sequences, E. granulosus (sensu lato) has by now been subdivided into E. granulosus sensu stricto (including the formerly identified genotypic variants G1-3), …
