The Effects Of Different Organic Pastures On Dairy Heifer Growth And Development, Jacob A. Hadfield Aug 2020

The Effects Of Different Organic Pastures On Dairy Heifer Growth And Development, Jacob A. Hadfield

All Graduate Theses and Dissertations

Raising dairy heifers in a certified organic setting can be difficult for producers. Conventionally, heifers are raised in a confined setting, and fed a total mixed ration (TMR) that is balanced daily to contain all the needed nutrients for developing heifers. Organic producers can use a TMR in their operations, but due to high organic feed costs, many choose to raise their heifers in pasture-based systems. While pasture-based systems may lower costs, heifers on pasture commonly have lower rates of gain, which can be financially burdensome to producers. Grass-legume pastures may help improve rates of gain in heifers on pasture-based ...


Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange Aug 2020

Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange

All Graduate Theses and Dissertations

Eating a combination of forages with different chemistries (i.e., nutrients, beneficial compounds such as tannins) may enhance ruminant nutrition and reduce environmental impacts relative to eating single forages. I explored the influence of offering sheep and cattle all possible combinations of tanniferous (i.e., plants with tannins; birdsfoot trefoil, sainfoin) and non-tanniferous legumes (i.e., plants without tannins; alfalfa) or their monocultures on animal performance, behavior, and methane and nitrogen (N) emissions. Offering choices among these legumes to penned sheep improved intake and diet digestibility relative to feeding monocultures. Mixtures selected by sheep were better digested than mixtures containing ...


Reusable Light-Activated Antimicrobial Materials Prepared With Food Ingredients, Andrew T. Gagon Aug 2020

Reusable Light-Activated Antimicrobial Materials Prepared With Food Ingredients, Andrew T. Gagon

All Graduate Theses and Dissertations

Microbial contamination and proliferation in food processing, distribution and storage continues to be a real risk in spite the wide variety of food processing and preservation techniques available. Some of these techniques (such as heat treatments and the use of chemical preservatives) may require substantial amounts of energy and their effects in the general population and the environment may be harmful. This has generated an interest over alternative methods of food preservation. The use of reusable light-activated materials may represent an effective approach. In this study, a polypropylene plastic was modified with either zein, which is found in corn, or ...


Effects Of Flywheel Resistance Training On Muscle Function And Sport-Specific Performance In Collegiate Club Water Polo Players, Jennifer Xu Aug 2020

Effects Of Flywheel Resistance Training On Muscle Function And Sport-Specific Performance In Collegiate Club Water Polo Players, Jennifer Xu

All Graduate Plan B and other Reports

Flywheel training has been shown to be beneficial for improving a multitude of muscle function and performance parameters, but its short-term training effects on athletic performance have yet to be established. PURPOSE: To investigate the effects of four weeks of flywheel squat training on lower body muscle function adaptations and sport-specific performance in collegiate club water polo players. METHODS: Thirteen men and women who participated in collegiate club water polo performed flywheel squat training twice a week for four weeks. Isokinetic knee extension peak power (PP) and peak torque (PT), flywheel squat peak power (FPP) and mean power (FMP), countermovement ...


Improving Our Ability To Estimate Vital Rates Of Endangered Fishes On The San Juan River Using Novel Applications Of Pit-Tag Technology, J. Benjamin Stout Aug 2020

Improving Our Ability To Estimate Vital Rates Of Endangered Fishes On The San Juan River Using Novel Applications Of Pit-Tag Technology, J. Benjamin Stout

All Graduate Theses and Dissertations

Estimating demographic parameters, such as survival and abundance, with accuracy and precision is vital for detecting trends in populations and assessing the effectiveness of management actions. In most cases, a lack of capture data make estimating parameters very challenging. The use of new technologies to increase the amount of remotely collected data is increasing, but brings new limitations and analytical issues to be resolved. One of those new technologies is the use of a mobile floating PIT-tag antenna to detect PIT-tagged fish. The issue that arises with this technology is determination of the status of detected tags (i.e., live ...
