“…Processing of the test ingredient may also affect the availability of choline. Berry et al (1943b) reported that expeller SBM supported significantly better growth than solvent-extracted SBM when fed in a corn-based diet without supplemental choline. However, most feed ingredient tables list solvent-estracted SBM as having more total choline.…”

“…However, Berry et al (1943a), Marvel et al (1943) and Mishler et al (1946) reported that corn-SBM diets containing approximately 35% SBM resulted in consistently poor growth unless the diets were supplemented with choline. In a later report Berry et aL (1943b) concluded that neither solvent-nor expeller-processed SBM supplied an adequate quantity of choline for satisfactory chick growth. Without supplemental choline, expeller SBM supported significantly better growth than solvent SBM.…”

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%.

“…When the results obtained in these experiments are compared with those obtained by Berry et al (1943b), it is evident that distillers' solubles are of considerable value in supplying the deficient factor or factors which are supplied by choline. 1.…”

“…They also indicated that their diet probably required no supplement other than methionine for optimum growth. Berry, Carrick, Roberts, and Hauge (1943) believed that the difference in growth, when soybean oil meal replaced animal protein feeds in chick rations, was largely due to a lack of some of the essential growth factors or vitamins in soybean oil meal rather than a difference in protein quality. Their data indicated a lack of adequate available choline for rapid growth in rations containing approximately one-third soybean oil meal.…”
