The Equitarian Initiative: International Humanitarian Aid Using Horses, Angela Gebhart Jan 2011

The Equitarian Initiative: International Humanitarian Aid Using Horses, Angela Gebhart

The Journal of Undergraduate Research

This harrowing comment from a Mexican laborer echoes the worldwide importance of working horses, mules, and donkeys. For many in the United States, a horse is a source of recreation, a sport vehicle of sorts, a decoration, or a pet. For most other parts of the world, a working equid (horse, donkey, or mule) is a family’s sole vehicle, a day laborer, and the only constant source of income available. Many of these communities lack a steady food source for the animals, much less a competent veterinarian; thus, the world’s veterinarians treat only about 10% of the world’s total equid …

High Resolution Hybrid Mass Spectrometry For The Determination Of Marine Biotoxins, Azaspiracids, And Their Biotransformation Products., Zuzana Skrabakova Jan 2011

High Resolution Hybrid Mass Spectrometry For The Determination Of Marine Biotoxins, Azaspiracids, And Their Biotransformation Products., Zuzana Skrabakova

Theses

Azaspiracids (AZAs), polyether marine toxins, are produced by marine microalgae and accumulate in filter-feeding bivalve molluscs, such as mussels, clams, oysters and scallops, while grazing on phytoplankton, from which they derive nutrition. Although being discovered quite recently, AZAs have caused several human intoxication events and thus became a problem for health authorities and shellfish industries. The rapid development of highly sensitive liquid chromatography multiple tandem mass spectrometry (LC-MS/MS, LC-MS") methods enabled the identification of numerous AZA analogues and added to the control of shellfish contamination. Tandem mass spectrometry techniques, while being highly selective and sensitive for determination of AZAs in …

The Effects Of Nutritionally‐Modulated Prepartum Bcs On Pre‐ And Postpartum Metabolic Responses, In Vitro Lipid Metabolism And Performance Of Multiparous Beef Cows, Melissa Dale Hudson Jan 2011

The Effects Of Nutritionally‐Modulated Prepartum Bcs On Pre‐ And Postpartum Metabolic Responses, In Vitro Lipid Metabolism And Performance Of Multiparous Beef Cows, Melissa Dale Hudson

University of Kentucky Doctoral Dissertations

Increased BCS at calving due to nutritional manipulation during the prepartum period resulted in greater mobilization of body fat after calving, regardless of plane of nutrition during the last 60 d of gestation. Although fatter cows were shown to have greater mobilization of reserves during the postpartum period, they maintained greater BCS at all points from calving to weaning compared to cows calving with fewer reserves at calving. A unique finding of this experiment was that the variation in BCS at calving was positively associated with BCS loss for cows fed to accrete BC during the prepartum period but was …

Review: Lipid Addition To Corn Finishing Diets, Virgil R. Bremer, Galen Erickson, Terry Klopfenstein Klopfenstein Jan 2011

Review: Lipid Addition To Corn Finishing Diets, Virgil R. Bremer, Galen Erickson, Terry Klopfenstein Klopfenstein

Nebraska Beef Cattle Reports

The fat content of distillers grains with solubles (DGS) partially accounts for DGS feeding value being greater than corn. Finishing diets containing DGS to supply up to 8% of diet DM as fat may be fed without depressing cattle performance. However, feeding diets containing 8% diet fat with corn oil depresses cattle performance. The difference in rumen metabolism of these two fats is due to physical protection of DGS fat from interaction with rumen microbes. Due to an unknown mechanism, condensed corn distillers solubles, a liquid fat source, does not limit ruminal metabolism like corn oil. Optimum dietary fat level …

Economic Impact Of Sulfur Levels In Distillers Grains Diets Fed To Beef Cattle, Jhones O. Sarturi, Darrell Mark, Galen Erickson Erickson, Terry Klopfenstein, Judson Vasconcelos, Virgil R. Bremer

Nebraska Beef Cattle Reports

An economic evaluation of a growth performance study (2011 Nebraska Beef Cattle Report, pp. 62-64) comparing wet or dry distillers grains with solubles (DGS) containing varying levels of sulfur was conducted. Diets containing DGS were more profitable than the control diets containing no co-product (Control). Wet DGS showed greater profitability than Control and dry DGS diets. Sulfur content in dry DGS did not affect profitability. Profits were lowest for Control and greatest for wet DGS (0.82% S) at 30% inclusion. Low sulfur concentration in wet DGS allows shipment to feedlots further away.

Economic Analysis Of Supplementing Ddgs To Grazing Steers, Andrea K. Watson, Terry Klopfenstein, Galen Erickson Erickson, Darrell Mark, Walter H. Schacht

Nebraska Beef Cattle Reports

A five-year study from 2005-2009 was conducted to evaluate differences in three grazing management strategies for backgrounding calves on smooth bromegrass pastures. Economic budgets were used to calculate profit differences. Steers supplemented an average of 5.3 lb/day of distillers grains were 90 lb heavier than either of the unsupplemented groups, which resulted in increased revenue of $49.38 for supplemented steers. Land costs were the same per AUM for all treatments but were decreased on a per head basis for pastures with supplemented cattle because cattle were stocked at higher rates than the control. Profit was greatest for the supplemented steers, …
