Effect Of Long-Term Dietary Fat Quality On Metabolic Health With A Special Focus On Dairy Fat, Allison L. Unger Jan 2021

Effect Of Long-Term Dietary Fat Quality On Metabolic Health With A Special Focus On Dairy Fat, Allison L. Unger

Graduate College Dissertations and Theses

Diet, and particularly dietary fat quality (i.e., fatty acid composition), is a significant modifiable risk factor in the development of metabolic diseases. However, whether the manipulation of long-term dietary fat quality may serve as an effective dietary strategy to mitigate metabolic disease risk during aging is not well defined. Accordingly, this work sought to investigate the role of life-long consumption of bioactive fatty acids from various food sources, and particularly dairy fat, on health maintenance and metabolic disease risk later in life. To address this issue, I assessed how long-term supplementation of dairy fat (butter oil), echium oil, or fish …


The Effect Of Physically Effective Undegradable Neutral Detergent Fiber And Rumen Fermentable Starch On Lactating Holstein Cows, Katherine Mae Smith Jan 2021

The Effect Of Physically Effective Undegradable Neutral Detergent Fiber And Rumen Fermentable Starch On Lactating Holstein Cows, Katherine Mae Smith

Graduate College Dissertations and Theses

In the dairy industry, a common way of adding energy to the diet is in the form of fermentable starch. However, an overabundance of fermentable carbohydrates can cause a buildup of volatile fatty acids that exceed the buffering capacity of the rumen. These changes can lead to negative health consequences such as subacute rumen acidosis and milk fat depression. Not only does a cow need readily fermentable sources of energy in her diet, but she also needs physically effective structural carbohydrates.Fiber has been a difficult portion of the diet to characterize as both the chemical and physical properties are important …


Healthcare Professionals’ Perceptions Regarding The Nutrition Of Dairy And Plant-Based Dairy Alternatives, Bridget Clark Jan 2021

Healthcare Professionals’ Perceptions Regarding The Nutrition Of Dairy And Plant-Based Dairy Alternatives, Bridget Clark

Graduate College Dissertations and Theses

Plant-based (PB) dietary patterns have seen an upsurge in popularity over the past two decades. With this, has come an increase in consumption of PB alternatives to animal food products, including alternatives to dairy. However, because PB dairy alternatives are nutritionally different from dairy, there is concern that consumers of these products may unknowingly fall short on essential nutrients in their diet. Healthcare providers are key sources of nutrition information for U.S. consumers. This work examined U.S. healthcare professionals’ beliefs and recommendations regarding dairy and PB dairy alternatives. Two methods were used: (1) analysis of all public comments submitted the …


The Effects Of Dietary Yeast Extracts On Rumen Microbiota And Fermentation In A Dual-Flow Continuous Culture Fermentation System, Lauren Baker Jan 2021

The Effects Of Dietary Yeast Extracts On Rumen Microbiota And Fermentation In A Dual-Flow Continuous Culture Fermentation System, Lauren Baker

Graduate College Dissertations and Theses

Dietary yeast supplements are a popular feed additive in ruminant diets as its inclusion can favorably alter the rumen microbiota and fermentation, and subsequently improve animal health and production. Yeast are a rich source of amino acids, peptides, organic acids, carbohydrates, lipids, vitamins, and minerals. Inclusion of nutrient-rich yeast and yeast extracts in the diet promote the growth of select groups of rumen microbiota, subsequently improving digestibility, volatile fatty acids, and pH profile. However, the large variability within yeast types and composition has created inconsistent results on these parameters, and further investigation into yeast product variability is crucial for understanding …
