The Effects Of Intermittent Fasting On Female Athletes: A Systematic Review, Courtnie Scarbrough

Theses and Dissertations

The intermittent fasting diet has a historical past, but recently, it has regained popularity as a weight loss strategy for the general public. Athletes have also picked up this specialized diet in search of a competitive edge. There are ample studies testing athletes of all levels, but most do not include females or report sex-specific results. This systematic review aimed to identify current research on the effects of intermittent fasting in the understudied population of female athletes. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search was conducted in three databases, including PubMed, Cochrane, …

The Contradictory Nature Of U.S. Laws And Nutrition Programs And Their Effects On Infant Feeding, Lily Patel

Journal of Food Law & Policy

The contradictory nature of U.S. laws, including the laws concerning infant feeding, though supposedly aligned with policies to promote wellness in Americans, can exacerbate gender and race inequality and work against the National Strategy. The overarching goal of U.S. laws concerning infant feeding is to ensure that infants are fed, nourished, and receive proper nutrition. However, the laws often appear to be directly contradictory to one another in the priorities they are promoting.

Impact Of Moisture Content And Composition On Flow Properties Of Dairy Powders, Katelynn Palmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Milk protein concentrate (MPC) and isolate (MPI), and milk permeate powder (MPP) are functional dairy powder products that are used in food applications worldwide. It is critical that environmental factors and physical powder characteristics during production and storage are controlled. When dairy powders are exposed to non-ideal conditions (high moisture, varying temperatures,) they can quickly become very sticky, and clumpy. When powders become sticky, their ability to easily flow is reduced. As a result, processing and storing the powders effectively and sustainably becomes very difficult.

In the first study, an analysis method was created to test the general flow behavior …

Understanding The Impact Of Physicochemical Modifications On The Cold Gelling Behavior Of Micellar Casein Concentrate Dispersions, Nathan Pougher

All Graduate Theses and Dissertations, Fall 2023 to Present

When skim milk is filtered via microfiltration, the amount of casein (one of the major milk proteins) in solution can be concentrated. When casein content is high enough (>15%), the solution forms a gel at cold temperatures. With growing trends in the food industry towards simplistic ingredient labels, commonly used gums and stabilizers in the dairy industry are becoming less preferred. In the future, there is potential for the gelling properties of micellar casein to be applied to dairy products as a thickener or stabilizer, but the mechanism behind gel formation isn’t understood well. In this study, the gel …

Feed Value And Utilization Of Corn Residue: Implications For Cow Performance And Grazing Strategies, Kaylee E. Wheeler

Department of Animal Science: Dissertations, Theses, and Student Research

Two experiments were conducted to determine the correlation of corn residue feed value and utilization on cow performance and potential grazing strategies. A qualitative observation of corn residue grazing by 13 cattle herds across Nebraska was conducted over two years. Based on producer reported grain yields and stocking rates, it was found that these producers were generally not as aggressive as the recommended 1.2 animal unit months (AUM) for each 6,280 kg/ha (100 U.S. bushels/acre) of harvested grain. They stocked 17 to 101% of the recommendation and on average used 63% of the carrying capacity. Across herds, average body condition …

Predicting Body Weight Of Cattle And Nutrient Digestion Of Individual Sweet Bran Components To Improve Beef Cattle Production Efficiency, Dalton J. Anderson

Efficiency is of high importance to beef cattle producers to ensure that beef cattle are being raised without unnecessary resource use. Two separate experiments were conducted to evaluate potential strategies to improve efficiency in beef cattle production. A metabolism study was conducted to evaluate digestion parameters of individual Sweet Bran components. The objective was to determine the effects of diet components on nutrient digestion and rumen fermentation parameters. The individual components of Sweet Bran (Corn bran, solvent-extracted germ meal, and corn steep liquor) were included at 40% diet dry matter (DM) in a steam-flaked corn (SFC) based diet. A SFC-based …

The Evaluation Of Feed Additives On Reducing Enteric Methane Production From Cattle, Reba L. Colin

Department of Animal Science: Dissertations, Theses, and Student Research

Environmental sustainability can be positively impacted by the inclusion of feed additives to reduce enteric methane production from cattle. Methane production can be affected by feed additives that either alter the rumen environment or act as methanogenesis inhibitors. A reduction in methane from cattle can contribute to meeting carbon neutrality.

A metabolism study was conducted to evaluate Alga 1.0, a product containing bromoform, fed to cattle to evaluate the effects on gas emissions. Treatments were (0, 69, or 103 g/d Alga 1.0) fed in a corn-based diet. Headbox-style indirect calorimeters were used to measure gas emissions. Feeding Alga 1.0 linearly …

The Impact Of Silage Inclusion In Diets With Different Corn Processing And The Effect Of Natural And Conventional Feeding Programs On Finishing Cattle Performance, Jessica L. Miller

Department of Animal Science: Dissertations, Theses, and Student Research

A finishing experiment was conducted to determine the effects of natural and conventional feeding programs on finishing performance of steers and heifers. Factors were conventional and natural feeding programs in steers and heifers. Cattle assigned to the conventional program were fed diets that contained Rumensin (Elanco Animal Health), Tylan (Elanco Animal Health), MGA (Zoetis), and received growth promoting implants whereas cattle in the natural program received neither. Compared to natural fed cattle, G:F was improved by 15.5% when heifers were fed in a conventional program (P < 0.01) and 23.8% when steers were fed in a conventional program (P < 0.01). The incorporation of implants and feed additives within the finishing period increased …

Forages And Technology Management In Growing And Finishing Beef Cattle Systems, Kelton Cole Adair

Department of Animal Science: Dissertations, Theses, and Student Research

A systems study evaluated the effects of an implant [25.7 mg estradiol (Compudose; Elanco Animal Health)] at two rates of gain (LOW: 0.45 kg/d and HIGH: 0.9 kg/d) applied during the winter backgrounding phase in drylot and winter grazing systems and its effects on subsequent phases of production. HIGH supplementation with an implant during the winter backgrounding phase in the drylot system yielded the greatest ending body weight (EBW) during the summer backgrounding phase (P = 0.04). LOW supplementation, without an implant, improved summer backgrounding average daily gain (ADG; P = 0.05) while achieving similar carcass adjusted final body …

Factors Affecting Forage Quality And The Subsequent Response In Production And Energy Metabolism In Lactating Jersey Cows, Kassidy Kate Buse

Department of Animal Science: Dissertations, Theses, and Student Research

Forage quality is the potential of a forage to produce a production response in animals. Because of how essential they are in dairy cattle rations, forages can have major influence on the behavior and production of dairy cattle. In experiment 1, the effect of forage fragility on the rumen environment and digestibility was evaluated. Increasing the inclusion of a less fragile forage led to greater rumen retention time, which resulted in lower rumen pH and greater NDF digestibility. Experiment 2 evaluated the effects of diets high in either corn silage or alfalfa haylage supplemented with either corn- or soybased protein …

Early-Life Supplementation Of Omega-3 Polyunsaturated Fatty Acids Improved Growth And Skeletal Muscle Glucose Metabolism In The Heat Stress-Induced Iugr Neonatal Lamb, Melanie Ryann White

Department of Animal Science: Dissertations, Theses, and Student Research

Our 1^st study determined whether metabolic deficits of IUGR-born neonatal lambs can be improved by ameliorating elevated inflammatory tone. Supplementation with ω-3 polyunsaturated fatty acids (ω-3 PUFA) improved hindlimb insulin-stimulated glucose oxidation rates and basal lactate secretion. Ex vivo skeletal muscle-specific glucose oxidation rates were improved when heightened inflammatory tone was moderated. Pancreatic β cell function in response to hyperglycemia was improved by ω-3 PUFA supplementation. Tempered inflammatory tone also partially recovered skeletal muscle glycogen stores. Thus, we found that targeting heightened inflammatory tone inherent in IUGR-born neonatal lambs moderately improved glucose metabolism and pancreatic β cell …
