Research Project: Evaluating the Benefits of Soybean with High Protein and High Sulfur Amino Acid Content on Gain and Feed Efficiency of Poultry

Location: Plant Genetics Research

Project Number: 5070-21000-044-003-A
Project Type: Cooperative Agreement

Start Date: Oct 1, 2022
End Date: Mar 31, 2024

Soybean is the preferred protein source for both poultry and swine feed. Recently, we have developed experimental soybean lines that not only contain significantly higher amounts of protein (42-45%) but also improved sulfur amino acid content (60 -70% higher). Here, we are proposing a feed trial project aimed at evaluating the potential of these newly developed soybean lines with high protein and high sulfur amino acid content to promote gain and feed efficiency of poultry.

Seeds of experimental soybean lines containing higher levels of protein with improved sulfur amino acid content will be multiplied at the cooperator's farm. Seeds will be harvested, and initial biochemical analysis will be performed. Protein concentration will be measured using commercially available nitrogen analyzer and amino acids will be measured by HPLC. Soy meal prepared from these experimental lines will be utilized for poultry feed trials.
