Summary Plant operating‐procedures and laboratory controls were set up to evaluate the quality of meal and oil which could be produced through each stage of commercial, prepress‐solvent‐extraction processing. By altering conventional, prepress‐solvent‐processing conditions and by increasing moisture during cooking and adding granular soda ash after cooking meats, cottonseed meal rations can be produced which are comparable in feed efficiency to soybean meal rations and satisfactory for feeding laying hens in amounts up to 10% of the total weight of the ration with no egg‐yolk discoloration and crude cottonseed oils with low F.F.A. and light color can be produced which refined to low Lovibond colors and with ferining losses approximating the chromatographic loss when miscella refined within minutes after separation from the source material with the exclusion of air and light.
