Cake meal as feed: soybean cake (meal), peanut cake (meal), cottonseed cake (meal), rapeseed cake (meal), sunflower seed cake (meal), sesame seed cake. Its main nutrients are recorded as follows. (1) soybean cake (meal). Soybean cake (meal) is soybean by pressing, with solvent leaching to extract the residue of oil. Containing 45% protein, 1% crude fat, nitrogen-free leachate 30.7%, 6.5% crude fiber, 6% crude ash; soybean cake is the residue of soybean oil by mechanical pressing. Its crude protein 39.8% -42%, crude fat 4% -7.3%, nitrogen-free leachate 27.4% -31.0%, crude fiber 5.6-6%, crude ash 4.9% -6% 0 (2) peanut cake (meal). Peanut cake (meal) is peanut by shelling, not shelling press or solvent leaching oil extraction residue o shelling of peanut cake nutrients generally contain record: crude white matter 40.3%, crude fat 8.6%, nitrogen-free leachate 29.2%, crude fiber 8.3%. Not shelled peanut cake, crude fiber content m. High (25.8%), other nutrients containing the most relatively low. (3) cottonseed cake (meal). Cottonseed cake (meal) is the residue of cottonseed shelling, fluffing after taking oil. Cottonseed meal nutrients contain the most: 36% crude protein, crude fat 1%, crude fiber 13.5%, crude ash 6%. High-quality cottonseed cake (meal) and its free cotton phenol less ((0.02% or less), protein and lysine containing more records, high nutritional value of feed. (4) rapeseed cake (meal). Canola cake (meal) is the residue of rapeseed oil extraction. Rapeseed cypress nutrient content of the average record: 35% crude protein, crude)! Line animal 1%, 11% crude fiber, crude ash 6.5%. (5) sunflower seed cake (meal). Sunflower seed cake (meal) is sunflower seed oil extraction residue. After hulling oil sunflower seed cake nutrient content is generally: crude protein 41.8%. Crude fat 7%, crude fiber 13%, nitrogen-free leachate 31.4%, crude ash 6.8%; hulled sunflower seeds (meal) of the nutritional content of the record is generally: 45.7% crude protein, 4% crude fat, crude fiber 11.1%, nitrogen-free leachate 31.5%, crude ash 7.7%. Not shelled sunflower seed cake (meal), the crude fiber content of the record is very high (24% and 34%, respectively), the other components of the record is relatively low. (6) sesame seed cake. Sesame seed cake is sesame seeds by oil extraction after the residual performance. Its nutrient content is generally recorded: 48% crude protein, crude) 3% -4%, crude fiber 2% -3%, nitrogen-free leachate 30% -35%, crude ash 9%. Sesame seed cake is a good source of protein feed for fish, can be fed directly, can also be used as feed ingredients.
