Veterinary Science Faculty Publications

Equine protozoal myeloencephalitis (EPM) remains an important neurologic disease of horses. There are no pathognomonic clinical signs for the disease. Affected horses can have focal or multifocal central nervous system (CNS) disease. EPM can be difficult to diagnose antemortem. It is caused by either of 2 parasites, Sarcocystis neurona and Neospora hughesi, with much less known about N. hughesi. Although risk factors such as transport stress and breed and age correlations have been identified, biologic factors such as genetic predispositions of individual animals, and parasite-specific factors such as strain differences in virulence, remain largely undetermined. This consensus statement …

Cross-Sectional Analysis Of Salivary Cortisol And Cyathostome Infestation In Horses, Danielle L. Keating Jan 2016

Cross-Sectional Analysis Of Salivary Cortisol And Cyathostome Infestation In Horses, Danielle L. Keating

Undergraduate Honors Thesis Projects

With an increase in anthelmintic resistance and decreased efficacy of many commercial dewormers, understanding factors that contribute to parasite infestations in horses is integral to their management. The goal of this study was to look at the potential relationship between parasites and stress response by evaluating salivary cortisol levels and cyathostome egg shedding levels. Using a sample size of n = 200 horses from the state of Ohio, fecal and saliva samples were collected from each horse. Fecal egg counts were performed for each horse with a modified Stoll method, and saliva samples were tested with an enzyme-linked immunosorbent assay …

Development Of An In Vivo Exsheathment Assay Of Infective L3 Haemonchus Contortus Larvae In Fistualated Sheep, Holly N. Williams, Katherine Petersson, Carly Barone May 2015

Development Of An In Vivo Exsheathment Assay Of Infective L3 Haemonchus Contortus Larvae In Fistualated Sheep, Holly N. Williams, Katherine Petersson, Carly Barone

Senior Honors Projects

Purpose: Gastrointestinal nematodes (GIN) hinder the sustainable production of small ruminants on pasture and parasite resistance to chemical dewormers is becoming a growing concern. Condensed tannin containing legume forages are being tested to evaluate their anti-parasitic properties and potential contribution to an overall parasite control program for small ruminants such as sheep and goats. One of the most pathogenic GIN of small ruminants is Haemonchus contortus. The final step to full infectivity of H. contortus third stage larvae (L3) is exsheathment in the rumen. The objective of this study was to establish an in-vivo exsheathment assay in fistulated sheep …

Nutrient Digestibility And Ruminal Ph Of Finishing Diets Containing Dry Milling Byproducts With And Without Oil Extraction, Melissa L. Jolly-Breithaupt, Adam L. Shreck, Jana L. Harding Harding, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson Jan 2015

Nutrient Digestibility And Ruminal Ph Of Finishing Diets Containing Dry Milling Byproducts With And Without Oil Extraction, Melissa L. Jolly-Breithaupt, Adam L. Shreck, Jana L. Harding Harding, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

A metabolism trial was conducted to determine the effects of corn oil removal in condensed distillers solubles (CDS) and modified distillers grains plus solubles (MDGS) on nutrient digestibility and ruminal pH. Oil removal had no impact on DM, OM, or NDF digestibility in steers fed CDS or MDGS. However, steers fed de-oiled CDS had a lower fat digestibility than steers fed normal CDS. Average ruminal pH was lower for steers fed de-oiled MDGS than for steers fed normal MDGS, however no difference within CDS was observed.

Mineral Composition Of Beef Cattle Carcasses, Andrea K. Watson, Jana L. Harding, Matt P. Mccurdy Curdy, Matt J. Hersom, Kristin E. Hales, Clint R. Krehbiel, Galen E. Erickson Jan 2015

Mineral Composition Of Beef Cattle Carcasses, Andrea K. Watson, Jana L. Harding, Matt P. Mccurdy Curdy, Matt J. Hersom, Kristin E. Hales, Clint R. Krehbiel, Galen E. Erickson

Nebraska Beef Cattle Reports

Mineral retention was measured in 76 beef steers. Cattle were grown at different rates of gain and then finished on a common diet. Calcium and P retention were not affected by treatment and were similar between the growing and finishing periods averaging 4.2 g P and 10.8 g Ca /100 g protein gain across both experiments. As ADG during the growing period was decreased, K, Mg, and S mineral retention during the finishing period were increased. Expressing mineral retention as g/100 g protein gain reducedvariation due to animal size and ADG and suggests that current NRC predictions are accurate.

Anaerobic Digestion Of Feedlot Manure, Andrea K. Watson, Adam L. Shreck, Amy M. Schmidt Schmidt, Terry J. Klopfenstein, Galen E. Erickson Jan 2015

Anaerobic Digestion Of Feedlot Manure, Andrea K. Watson, Adam L. Shreck, Amy M. Schmidt Schmidt, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Cattle diet can impact manure quality and quantity but has minimal impacts on methane production from anaerobic digestion of manure. Quality of manure, measured as OM, does affectmethane production and is largely impacted by the environment cattle are housed in and methods used to collect manure. As the amount of ash contamination of manure was increased, or OM content of the manure was decreased, organic matter degradation and methaneproduction were decreased. With adequate daily cleanout of ash from digesters, open-lot beef cattle manurecan be used for anaerobic digestion.

Mineral Composition Of Serial Slaughter Holstein Carcasses, Andrea K. Watson, Trent J. Mcevers, Lee-Anne J. Walter Walter, Nathan D. May, Jacob A. Reed, N. Andy Cole, Ty E. Lawrence, James C. Macdonald, Galen E. Erickson Jan 2015

Mineral Composition Of Serial Slaughter Holstein Carcasses, Andrea K. Watson, Trent J. Mcevers, Lee-Anne J. Walter Walter, Nathan D. May, Jacob A. Reed, N. Andy Cole, Ty E. Lawrence, James C. Macdonald, Galen E. Erickson

Nebraska Beef Cattle Reports

Carcasses of 115 Holstein steers were divided into lean, bone, internal cavity, hide, and fat tissues for analysis of P, Ca, K, Mg, and S retention. Every 28 days, five steers from each of two treatments, fed Zilmax for 20 days prior to harvest or not fed Zilmax, were harvested. There were no differences due to treatment or days on feed when mineral retention was expressed as g/100 g of protein gain. Expressing mineral retention relative to protein gain reduced variation due to rate of gain and animal size.

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 Jan 2015

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.

An Economic Analysis Of Conventional And Alternative Cow-Calf Production Systems, Jason M. Warner, Andrea K. Watson, K. H. Jenkins Jenkins, Rick J. Rasby, Kate Brooks, Terry J. Klopfenstein Jan 2015

An Economic Analysis Of Conventional And Alternative Cow-Calf Production Systems, Jason M. Warner, Andrea K. Watson, K. H. Jenkins Jenkins, Rick J. Rasby, Kate Brooks, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Profitability through weaning was predicted for conventional and alternative cow-calf production systems using various input price scenarios. At base input price levels, conventional systems were more economical than alternative systems. As pasture price increased, alternativesystems became cost effective. Feeding cows year-round in a confinement setting appeared the least economical; however, an alternative system combining summer drylot feeding with cornstalk grazing is projected to be economically competitive given an increasing abundance of corn residue.

Effects Of Calf Age At Weaning On Cow And Calf Performance And Feed Utilization In An Intensive Production System, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein Jan 2015

Effects Of Calf Age At Weaning On Cow And Calf Performance And Feed Utilization In An Intensive Production System, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

The effects of calf weaning age on cow and calf performance, reproduction, and feed utilization were investigated in a two-year study. Early weaning increasedcow BW in January. Pregnancy rates were not impacted by calf age at weaning. Dry matter intake (DMI) was similar between normal-weaned cow-calf pairs and early-weaned cows and calves. Feed requirements and utilization were comparable between early- and normal-weaned pairs when fed high energy diets, implying weaning decisions should be made on the basis of management rather than feed efficiency.

Evaluation Of The Impact Of An Alternative Corn Residue Harvest Method On Performance And Methane Emissions From Growing Cattle, Janessa J. Updike, Anna C. Pesta, Robert G. Bondurant Bondurant, James C. Macdonald, Samodha Fernando, Galen E. Erickson, Terry J. Klopfenstein Jan 2015

Evaluation Of The Impact Of An Alternative Corn Residue Harvest Method On Performance And Methane Emissions From Growing Cattle, Janessa J. Updike, Anna C. Pesta, Robert G. Bondurant Bondurant, James C. Macdonald, Samodha Fernando, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A growing study was conducted to evaluate the impact of alternative corn residue harvesting methods and inclusion of Rumensin® on performance and methane to carbon dioxide ratio (CH4:CO2) of steers. Use of the alternative harvesting method resulted in greater ADG and improved F:G ratio than traditionally harvested cornstalks. Rumensin increased ADG and improved DMI; however, it did not have an impacton F:G ratio. Altering the composition of baled corn residue did affect CH4:CO2, while inclusion of Rumensin, whether included in the diet on a constant or rotational basis, had no impact.

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 Jan 2015

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.

Digestibility Of Calcium Oxide Treated Corn Residue With De-Oiled Distillers Grains, Sarah J. Peterson, Meredith L. Bremer, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson Jan 2015

Digestibility Of Calcium Oxide Treated Corn Residue With De-Oiled Distillers Grains, Sarah J. Peterson, Meredith L. Bremer, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson

Nebraska Beef Cattle Reports

A digestion study was conducted to evaluate diets containing calcium oxide treated corn residue in combination with de-oiled distillers grains in forage based growing diets. Chemical treatment did not affect digestibility of DM, OM, or NDF. However, concentration of distillers grains did improve DM and OM digestibility. The use of chemically treated residue in combination with distillers grains in growing diets may not impact diet digestibility.

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 Jan 2015

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.

Evaluation Of Changes In Nutritional Quality Of Corn Residue Over Time, Mandi Jones, James C. Macdonald, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson, Keith Glewen, Andrea K. Watson

Nebraska Beef Cattle Reports

Irrigated corn residue was sampled across time in order to determine changes in quality and proportion of corn residue as the plant dried and was exposed to effects of weathering. Corn plants from two hybrids were planted on two different planting dates and harvested at periodic intervals from August 2012 to December 2012. Proportions of stem, blade/sheath, husk/shank, and cob made up smaller components of total plant DM as it matured, with the largest relative reduction occurring in the blade/sheath or stem. Hybrid impacted TDN values primarily because the 119 day hybrid was less mature at the early sampling dates.

Efficacy Of Bovatec 2.2 Mineral Blocks For Cattle Grazing Crested Wheatgrass Pastures, Karla H. Jenkins, Jacob A. Hansen, Matt K. Luebbe Luebbe

Nebraska Beef Cattle Reports

A grazing study was conducted to determine if providing Bovatec® in a trace mineralized salt block would improve cattle performance over cattle provided a trace mineralized salt block without an ionophore while maintaining block consumption below 2 oz/head/day. Average daily block intake was 1.40 and 1.25 oz/day for the Bovatec and control cattle, respectively. Lasalocid consumption was 193 mg/head/day. Although cattle consuming the Bovatec block gained 5% more than the control cattle, this was not significant (1.75 vs 1.67 lb/day, respectively). Supplying an ionophore through a self-feeding block may not improve gain compared to supplying mineral alone in a self-feeding …
