“…Without supplemental choline, expeller SBM supported significantly better growth than solvent SBM. Camp et al (1955) also observed a response from supplemental choline when added to a diet containing 31% SBM and 3% fish solubles. The dietary choline requirement of young chicks fed a corn-casein diet has recently been evaluated by Ngo and Coon (1974) and found to be 834 ppm.…”

“…Suggestions of less than 100% availability for the choline found in ingredients commonly used in practical-type diets are found in the work of Berry et al (1943a,b), Marvel et al (1943), Mishler et al (1946 and Camp et al (1955). They found corn-SBM diets having over 30% SBM and containing other practical ingredients high in choline (fishmeal, distillers dried solubles) to be inadequate in choline.…”

Growth assays were conducted with 8-dayold crossbred chicks to evaluate the available choline in 44 and 49% protein soybean meals, and also in whole heat-treated soybeans. A choline-free (experimental basal diet)pretest diet was imposed from day 5 to 8 posthatching to diminish choline stores. Soybean sources were added at 5 and 10% to the basal diet, and a choline response curve was generated using 0, 175, and 350 ppm choline contributed from crystalline choline chloride. Slope-ratio and standard curve techniques were used to quantify the available choline content of each ingredient tested. Two sources of dehulled soybean meal were found to contain 1,614 and 2,026 ppm available choline, respectively. The latter sample was also evaluated in the presence of 2-amino-2-methyl-l-propanol, a specific inhibitor of choline biosynthesis, and a value of 2,024 ppm was obtained. The whole bean and 44% CP soybean meal were found to contain 1,844 and 1,664 ppm available choline, respectively. Using accepted table values (2,850, 2,743 and 2,420 ppm for dehulled, regular and whole bean, respectively) the availability of choline in the soybean products tested appears to range between 60 and 75%.
