玉米含淀粉多,粗纤维仅2%--2。5%,适口性好;但粗蛋白质、矿物质和维生素含量均不能满足猪体需要,必须与其他饲料搭配。玉米关日粮中所占比例不宜超过50%。在育肥后期用红薯干、麦类、豌豆取代一部分玉米,可获得高品质 的肉脂。稻谷含粗蛋白质8%,无氮浸出物63%,但粗纤维多有坚硬外壳,喂饲前须粉碎。其饲用价值相当于玉米的80%--90%。大麦有硬壳,喂用前须粉碎,粗蛋白质含量高于玉米,达10%--12%,脂肪、钙和维生素A、维生素D,尼克酸、维生素B2含量比玉米高3倍。用大麦喂的猪,屠体脂肪洁白硬实,属上等饲料。在日粮中添加量可达30%。饲用价值相当于玉米的90%。
Corn starch, crude fiber 2%2 only. 5%, palatability is good; but crude protein, minerals, and vitamins are not able to satisfy the need to pig body must match with other feed. The proportion of corn in the diet should not be more than 50%. Dry, sweet potato in the later stage of fattening of wheat and pea to replace some corn, can obtain high quality meat and fat. Rice contains crude protein 8%, nitrogen free extract 63%, but more than a hard shell fiber, feed before the need to be crushed. 80%90% feeding value equivalent to corn. Barley has a shell, feed used should be crushed, crude protein content than corn, 10% - 12%, fat, calcium and vitamin A, vitamin D, niacin, vitamin B2 content than corn high three times. Barley fed pigs, carcass fat white hard, an upper feed. In the diet, the amount can be added up to 30%. The feeding value of equivalent corn 90%.
稻糠又称米糠,含粗蛋白质 12%---13%,粗脂肪13%,粗纤维13%,磷1.3%,B族维生素丰富,但钙少。其营养价值与玉米相当,添喂量不宜超过30%,否则会降低肉脂品质,还容易导致猪群发生皮炎。麦麸粗蛋白质 含量可达12%--17%,质量高于小麦,含赖氨酸0.67%、蛋氨酸0.11%,维生素B族较丰富。但钙、磷比例不平衡,含能量较低。麦麸适口性好,体积膨大,具有轻泻性且耐贮藏。
Rice bran and rice bran,, crude protein content in 12% - - 13% of the 13% crude fat, crude fiber 13%, 1.3% phosphorus, rich in B vitamins, but less calcium. The nutritional value of corn, Tim feeding amount should not exceed 30%, otherwise it will reduce the fat of meat quality, also easily lead to dermatitis occurs in pigs. Wheat bran protein content of up to 12% - 17%, higher than the quality of wheat, containing lysine 0.67%, methionine 0.11%, vitamin B family is rich. But the ratio of calcium and phosphorus is not balanced, and the energy is low. Wheat bran palatability, volume expansion, and storage has a laxative.
