Research Project: Expansion of US Soybean Market with the Utilization of Full-fat High-Oleic Soybean Meal in Poultry Feed to Enrich Meat and Egg for Human Consumption

Location: Food Science and Market Quality and Handling Research Unit

Project Number: 6070-43440-013-08-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Oct 1, 2020
End Date: Sep 30, 2021

To determine the value-added utilization of high-oleic soybean varieties for the production of high-oleic soybean meal for use as a preferable feed ingredient for enhanced performance of animal production livestock (layer hens, broiler chickens and aquaculture) and nutritional enrichment of the products produced for human consumption.

We aim to acquire 1 ton of seed of each of a normal-oleic and a high-oleic varieties from Near Isogenic Lines (NILs) from Dr. Mian, Geneticist, Soybean & Nitrogen Fixation Unit-ARS, for production of full-fat soybean meal. Full-fat normal-oleic soybean meal and full-fat high-oleic soybean meal will be prepared using dry extrusion under the direction of Dr. Joseph, Feed Processing Specialist. Diets will be formulated and prepared at the NC State University Feed Mill under the direction of Dr. Fahrenholz, Feed Mill Specialist Three hundred and sixty birds (Layers-Exp1; Broilers-Exp 2) will be randomly assigned to 3 treatments (6 rep/treatment): (1) Control-defatted soybean meal (prepared from normal-protein, normal-oleic soybean) + corn diet, (2) Full-fat, normal-oleic soybean meal + corn diet, (3) Full-fat, high-oleic soybean meal + corn diet, for 8-10 wks. Performance and quality and nutrition of the eggs and meat will be determined bi-weekly or at termination (10 weeks). Also, we aim to determine the effects of replacing fishmeal at 0%, 25%, 50%, 75% and 100% with high-oleic soybean meal on domesticated Striped Bass for 18 weeks at the NCSU Marine Aquaculture Center. Diets will be processed into extruded pellets with suitable floatation and particle size for fish. Fish will be fed to satiation 2-3 times per day, with treatments in quadruplicate and 100 fish/tank. Fish will be fed a control diet for 2 weeks for baseline data. Fish growth (total length), body weight, and survival will be determined. At termination, feed efficiency (weight gain/dry matter fed) and protein efficiency ratio (g weight gain/g dietary protein) and whole body proximate analysis will be determined. Experimental data collected will be analyzed for analysis of variation at P<0.05 significance level. An econometric analysis will be determined at the end of each feeding trial.
