Defining Amino Acid Requirements Of Pregnant Sows: Challenges And Opportunities, Christian D. Ramirez-Camba
Defining Amino Acid Requirements Of Pregnant Sows: Challenges And Opportunities, Christian D. Ramirez-Camba
Electronic Theses and Dissertations
The efficient use of protein in animal production is dependent on the protein supply and its constituent amino acids (AA) in relation to the animal's needs. Excess AA are deaminated, and the resulting nitrogen (N) is excreted, whereas suboptimal AA intake reduces animal performance. Both increased nutrient excretion and decreased animal performance reduce the overall efficiency of the production unit. In sows, AA requirements should be adequate for optimizing reproductive performance, as measured, for example, by the number of pigs produced per sow per year while limiting N excretion. There is a desire to feed pregnant sows AA levels that …
Winter Snow Depth In Arctic Alaska Results In Complex Changes In Caribou Forage Quality, Jessica C. Richert
Winter Snow Depth In Arctic Alaska Results In Complex Changes In Caribou Forage Quality, Jessica C. Richert
Electronic Theses and Dissertations
Caribou (Rangifer tarandus) rely on the short growing season for much of their annual nutrition, making them susceptible to even small changes in forage quantity and quality. Body condition in the summer and fall is linked to winter survival rates and fecundity in cows, critical factors in the robustness of caribou populations. Due to a warmer, wetter climate, snowfall is predicted to increase over Alaska’s North Slope in the next several decades. Deeper snow results in higher soil temperatures, allowing microbial mineralization of nitrogen to continue throughout the winter and increasing the availability of nitrogen for plants in spring and …
The Efficacy Of Protein Supplementation On Attenuating Muscle Atrophy Following Disuse In The Collegiate Population, Leah Kroeger
The Efficacy Of Protein Supplementation On Attenuating Muscle Atrophy Following Disuse In The Collegiate Population, Leah Kroeger
Electronic Theses and Dissertations
The purpose of this study is to determine the effects of a protein supplementation protocol through a period of muscular disuse in maintaining muscle mass, strength, jump force production, and cross-sectional area in the collegiate population. Two groups of healthy collegiate participants underwent two weeks of unilateral lower limb suspension (ULLS), during which the control group consumed a normal diet and the treatment group received an additional 75 g of protein supplementation. Lean mass, strength, and force production were measured between dietary intakes at baseline and following immobilization. Muscle area was lost between both groups following ULLS (treatment, - 282.8 …
Effects Of Small Intestinal Starch Digestion And Dietary Lipid On Efficiency Of Nitrogen Use In Cattle, Ethan J. Blom
Effects Of Small Intestinal Starch Digestion And Dietary Lipid On Efficiency Of Nitrogen Use In Cattle, Ethan J. Blom
Electronic Theses and Dissertations
The objective of this research was to determine the effects of increases in energy available for gain from increased small intestinal starch digestion (SISD) and dietary lipid source and amount on the efficiency of N use in cattle. Five ruminally, duodenally, and ileally cannulated steers were placed in a 5 × 5 Latin square. Each received duodenal infusion of 1.5 ± 0.08 kg/d raw cornstarch and either 0, 30.9 ± 0.59, 62.4 ± 1.16, or 120.4 ± 3.39 g/d Glu, or 387.9 ± 17.47 g/d casein. Casein increased (P = 0.05) SISD. Similarly, greater duodenal Glu linearly (P = 0.02) …
Protein And Fiber Fortification Of White Pan Bread Using Food-Grade Distiller’S Dried Grains, Ashley Adamski
Protein And Fiber Fortification Of White Pan Bread Using Food-Grade Distiller’S Dried Grains, Ashley Adamski
Electronic Theses and Dissertations
Distiller’s dried grains (DDG) are a coproduct of ethanol production. DDG has been used historically as animal feed. However, in the past decade, ethanol production has dramatically increased causing a surplus of distiller’s grains and saturating the market. The use of DDG, which is high in both protein and fiber, to fortify baked goods is one option to reduce the excess of DDG while enhancing its economic value. The purpose of this study was first, to evaluate the washing process for DDG to make it food grade, and second to evaluate the effects of incorporation of food-grade DDG from two …
