Cottonseed Meal Prepared by Different Methods for Broiler Rations

Cottonseed Meal as a Substitute for Soybean Oil Meal in Poultry Rations ,

“…Patrick (1953) obtained better chick growth with solvent than with hydraulic cottonseed meal, using an all-vegetable diet. Morgan and Willimon (1954) compared screw-press, solvent and hydraulic cottonseed meals, singly and in combination with soybean oil meal versus an allsoybean oil meal diet. Chick growth was almost as good with the diet containing solvent cottonseed meal as the sole protein supplement as with the all-soybean oil meal diet.…”

Effect of fermentation with Aspergillus oryzae NRRL506 and Aspergillus janus NRRL1935 on the nutritional value of cottonseed meal

“…This was because screwpress and hydraulic CSM were higher in total gossypol and oil than solvent-extracted CSM (Morgan and Willimon, 1954).…”

“…About 30% of total U.S. production, however, consisted of prepress sol vent meals which were usually low in free gossypol and rela tively high in protein quality. The data shown in Table 1 ( Morgan and Willimon, 1954) describe the gossypol content of CSM prepared by various methods. Smith (1970) reported that the low, free gossypol level in screwpress and prepress solvent meals was not a signifi cant factor in determining the use of CSM in practical swine and poultry rations.…”

“…Most gossypol is removed during oil extraction. Morgan and Willimon (1954) reported that degossypolized, solventextracted CSM fed to broilers as the sole source of protein…”

The upper level of CSM for swine and poultry rations was determined by lysine, fiber and energy contents of CSM.…”
