Grow a significant quantity of low phytate soybeans as well as an equal quantity of commercial soybeans so that both may be harvested, dried, and processed into meal for direct feeding to broilers. Utilize our standardized soybean processing approach developed at TAMU with Dr. Richard Clough to produce low phytate and control meals. Examine the amino acid digestibility of low phytate and commercial meals with and without various feed enzymes in the presence or absence of feed with varying particle size and the fecal output of nitrogen and phosphorus. Develop optimum feed formulation guidelines for various mineral factors that have been found to affect digestion, e.g. calcium: available phosphorous ratio, salt: sodium bicarbonate balance, potassium in a low phytate environment. Continue work towards development of a bioassay to assess the amino acid digestibility on small lots of identity-preserved soybeans using solvent-extracted meal and a modified ileal digestibility test.
