Evaluation Of An Essential Oil Blend And A Novel Soybean Variety As Alternatives To Preventative Antibiotic Use In Monogastrics, Samantha Tauer
Evaluation Of An Essential Oil Blend And A Novel Soybean Variety As Alternatives To Preventative Antibiotic Use In Monogastrics, Samantha Tauer
Electronic Theses and Dissertations
Increasing consumer pressure to minimize antibiotic use and the implementation of the Veterinary Feed Directive in 2017 has increased research on alternatives to preventative antibiotics. This thesis focuses on evaluation of Ralco’s Microfused™ Essential Oils (MEO) fed to broilers and soybean meal from low allergenicity soybeans fed to weaned pigs and their potential use as alternatives to antibiotics. Essential oils are known to have antimicrobial, antioxidant, antiparasitic, and digestive stimulant effects. Low allergenicity (LA) soybeans were bred to contain significantly lower concentrations of the following anti-nutritional factors and allergenic proteins: Kunitz trypsin inhibitor, soybean agglutinin (lectin), and P34 (Gly m …
Impacts On Salmonid Rearing Performance With Use Of Dietary Bioprocessed Plant-Based Protein And Water Velocity, Jill Voorhees

The inclusion of bioprocessed soybean (Glycine max) meal was evaluated in five experiments using either Rainbow Trout (Oncorhynchus mykiss) or Brown Trout (Salmo trutta). In the first experiment, adult Erwin x Arlee strain Rainbow Trout were fed diets formulated so that bioprocessed soybean meal (BSM) replaced 0, 60, or 80% of the dietary fishmeal. There were no significant differences in gain, percent gain, feed conversion ratio, specific growth rate, intestinal morphology, relative fin lengths, or organosomatic indices. In the second experiment, juvenile Plymouth strain Brown Trout were fed diets formulated so that BSM replaced 0, 60, 80, or 100% of …
Regulation Of Local Auxin Metabolism During Soybean Nodule Development, Suresh Damodaran
Regulation Of Local Auxin Metabolism During Soybean Nodule Development, Suresh Damodaran
Electronic Theses and Dissertations
Legume-rhizobia symbiosis leads to the development of secondary root organs called nodules. Rhizobia bacteria housed inside nodules assimilate atmospheric nitrogen and convert them into plant usable forms thereby reducing the need for fertilizer application in crop legumes like soybean. Nodule development is a coordinated process orchestrated by multiple plant hormones. In soybean, the auxin responsive gene expression was detected in nodule primordia and in the periphery of mature nodules, primarily in nodule vasculature. Auxin hypersensitivity reduces nodule formation in soybean and also polar auxin transport inhibition at the site of nodule development is not crucial for determinate nodule formation. Therefore, …
Insecticidal Seed And In-Furrow Treatment Recommendations For Soybean And Sunflower, Brady Hauswedell
Insecticidal Seed And In-Furrow Treatment Recommendations For Soybean And Sunflower, Brady Hauswedell
Electronic Theses and Dissertations
Throughout the 2016 and 2017 growing season, field research experiments were replicated across South Dakota. Many times seed treatments are used prophylactic, which is neither good for the producers or the environment. Producers will be able to reduce production costs, if they only use a seed treatment when necessary. The purpose of the first experiment was to determine the effects of seed treatments in combination with planting date and seeding rate on soybean yield. To determine the effects, two years of field data from four eastern South Dakota locations were compared. Within each year and location we compared two planting …
