Soybean Oil Meal in Laying Rations

Abstract

SOYBEAN oil meal has been recognized as a valuable protein supplement for poultry rations and has been widely used especially in growing rations. Draper and Rhian (1942) found that combinations of pilchard meal with soybean oil meal (either 40:60 or 50:50) gave essentially the same efficiency as casein, when compared on the bases of growth of chicks or utilization of feed. They also found that when the supplementary protein was furnished by meat meal or any combination of meat meal and soybean oil meal, the gross values were less than that for soybean oil meal alone. Carver and associates (1943) reported that soybean oil meal could be used as a sole source of supplemental protein for growing chicks to four weeks when fed at levels of 19.6 percent. They also found that soybean oil meal plus meat scrap was not as satisfactory as soybean oil meal plus fishmeal.Soybean oil .
