What on earth are these things? Do not seem to be quite sure, oh, nutritional value is also varied, in the end how to apply is really a headache, seniors give some advice, in the end what attitude and way to apply it? It's easy to post. It should be discussed. I think the corn husk and corn bran are the same thing, that is, the seed coat outside the corn, the utilization rate is not high. The spray corn husk is sprayed on the corn husk with the soaking liquid of corn, so it is called spray corn husk, and there is a part of hydrolyzed monosaccharides. The utilization rate is higher than the corn husk-- seniors continue your point of view. Another question, the price of cottonseed meal is getting higher and higher, how much value is there in the feed? -- the price of soybean meal is high, the price of other miscellaneous meal raw materials is high-- brief introduction of corn by-product feed with the continuous expansion of the use of corn industry The corn used for feed has the trend of decreasing and rising year by year. In order not to increase the feeding cost of dairy cows, to provide a certain profit space for cattle breeders, and to reduce the contradiction between industrial corn and feed, some corn by-products which can be used as feed are introduced in terms of nutrition. Corn can be processed and produced as an industrial by-product feed corn contains starch, fiber, protein and fat (germ oil), so it is the raw material for processing a variety of industrial products (figure 1). Fig. 1 Industrial products produced by corn 1. Alcohol corn seeds are soaked to precipitate corn extract, and the rest can be fermented into alcohol. Alcohol is an important chemical raw material and fuel. The by-products of alcohol production are: 1) DDG, also known as dry distiller's grains. It is a by-product after corn is fermented into alcohol and then distilled to precipitate alcohol. The original sample generally contains 27.8% protein, the dry sample contains 29.7% protein, 8% fat, 12% fat, and contains NEm1.85Mcal/kg,NEg 1.25 Mcalmax kg (or 2.9NND/kg). The content of phosphorus and potassium is high, but the content of calcium is low. It is a high-quality protein supplement for dairy cows, and the tumor stomach rate of protein is higher than that of soybean meal, up to 50%-60%. The first daily feeding volume can reach 2.7~5.4kg. It can increase milk yield and prevent rumen acidosis. 2) DDGS is a product obtained by concentrating and drying some soluble substances and corn leachate produced in the process of fermentation and then adding them to dry distiller's grains. Except that the content of crude protein was slightly lower than that of DDG, the other characteristics and dosage were the same as DDG. 3) DDS, also known as dried corn extract. Because it is mixed with DDG to make DDGS, so this kind of product is less. 2. Corn starch corn is called corn residue after soaking and precipitating the leaching solution. After the corn residue is removed from the germ, and then crushed, after the starch is prepared by water separation, the remaining by-products can be used as feed. 1) Corn husk (CGF), also known as corn husk dregs, or corn fiber feed, corn husk bran, etc. It is a corn gluten feed made of corn gluten feed by dehydration after soaking, crushing and water separation in the production of starch. The output is about 5%. Its composition is: moisture 10.07%, crude protein 20.0% (20% ~ 22%), crude fat 5.7%, crude ash 1.0%, crude fiber 16.20% (6% 16%), nitrogen-free extract 57.45% (of which starch is more than 40%), NEm2.05Mcal/kg, NEg1.41Mcal/kg, NE L 1.87Mcal/kg (or 2.5NND/kg). Among the proteins contained, 30% of the proteins passed through the rumen. Neutral detergent fiber (NDF) 69%, acid detergent fiber (ADF) 30%, calcium 0.10%, phosphorus 0.30%. Feeding amount: first day of 4.5~13.6kg/. It can replace 50% to 80% wheat bran. There must be a transitional period of 2-3 days when feeding. Corn starch can be used as raw material to produce glutamic acid, vitamin C, monosodium glutamate, acetic acid, acetone or rubber, L-lactic acid and so on. 2) Corn yellow pulp water and its drying product-corn flour protein. Yellow pulp is a corn flour protein made from the supernatant of precipitated corn starch and dehydrated. Its output is about 4.5%. Yellow pulp water can be processed to produce glucose, fructose, maltose, oligosaccharides, whole sugar powder, maltodextrin, crystal fructose and so on. It can also be used to extract corn yellow pigment (isoprene), Zein and various amino acids (methionine about 40%, leucine 713%). The powder protein made from dehydration and drying contains more than 60% crude protein, and its nutritional value is comparable to that of fish meal and soybean meal. Its characteristics: ① color is good, palatability is good; ② digestibility is high (such as amino acid digestibility up to 95%); ③ high energy value (1.7~2.5Mcal/kg) ④ has milk-increasing effect. 3) Corn gluten meal, which is the washing solution when eluting starch or corn syrup when fructose is produced. The output is 0.5% and contains more than 60% crude protein. It is a kind of protein feed with high effective energy value, and the amino acid utilization rate of its single product is almost equal to that of soybean meal. 3. Corn germ and germ cake (meal). This is the product obtained after the removal of corn germ. Its output is 6.2% ~ 6.5%, which is the raw material for extracting corn oil. The oil content in germ is 46% ~ 48%, and the oil can be extracted from corn about 2.5 ~ 3.0 kg per 100kg. Corn germ has high energy content before oil extraction, so it can be used as energy and protein supplement for dairy cows in peak lactation period, and the daily dosage is controlled within 2. 5kg. Corn germ cake (meal) is obtained after pressing oil. Its yield is 100kg corn oil 3kg, corn germ cake (meal) about 3.2kg. Germ meal contains crude protein 22.6% (range 18% ~ 23%), fat 1.9%, starch 24%, crude fiber 9.5%, ash 3.8%, moisture 10%, lactation net energy 2.1Mcal/kg, calcium 0.06%, phosphorus 0.56%, which are protein feed for dairy cows. The dosage can account for 10% of the dry matter of the diet. The feed and output of some industrial by-products that can be processed by corn are shown in figure 2. Second, corn flour (dry) by-product feed-corn bran corn in the flour processing plant for dry grinding, after sieving the flour, the rest of the sieve is generally called corn bran, which can be used as feed for dairy cows. It consists of starch from corn bran, embryo and kernels. Its crude protein content is 9.1%, fat 6% (fully dry), lactation net energy 1.95 Mcal/kg, calcium 0.04%, phosphorus 0.18%, crude cellulose 10.9%. Contains NDF69%, ADF30%, 30% rumen protein. It belongs to a kind of transitional feed between energy feed and protein feed. The daily feeding amount can be up to 4.5-13.6 kg, instead of 50-80% of wheat bran. Third, several kinds of protein feed are processed with corn industry by-products as raw materials. 1. Corn compound protein feed (unfermented products), also known as corn gluten. It is prepared from corn husk (40% ~ 60%), corn gluten meal (15% ~ 25%) and corn impregnation solution (dry) (25% ~ 40%). The marked protein content is 10% ~ 20%, and the digestibility is 85%. It is a product between energy feed and protein feed. 2. Corn protein feed the by-products of corn starch-corn gluten meal, corn yellow pulp, corn fiber, chopped corn, etc., are mixed, pressed and defatted at high temperature, and then inoculated with several strains of acid-resistant bacteria for liquid / solid fermentation. The compound protein feed is produced after low temperature hydrolysis, puffing and drying. Product specifications: 1) moisture < 11% 2) crude protein 20% 35% 3) crude fat < 4% 4) crude ash < 5% 5) crude cellulose 10% 6) various amino acid contents: glutamic acid 6.331%, arginine 2.456%, methionine 1.211%, tryptophan 0.543%, phenylalanine 2.12%, lysine 1.091%. 7) Product color: yellow granule, slightly fermented smell. 8) characteristics: rich in nutrition, with the nutritional characteristics of a variety of miscellaneous grains, rich in various amino acids. 3. Corn spray protein is also called corn bran. It is a by-product after humidifying corn to produce starch and germ, and the main component is corn husk. Then spray the corn yellow pulp with high protein and energy content, so that its energy, protein and amino acids are greatly increased, and the corn spray protein is formed after drying. Its characteristics: ① color is yellow; ② palatability is good, animals like to eat; ③ energy 1.7 ~ 2.5Mcal/kg ④ digestibility more than 90%.

Registration-good stuff, learned, thank you. -- the price of soybean meal is beginning to fall. Thank you, landlord! Now I finally figured it out. -- there are so many things made from corn that you have to remember the pain in the skull-- got it. What is what-- it's too detailed, thank you. There are too many by-products, and there is also a by-product of glucose, which is called corn glycoprotein. I don't know if anyone has used it-the quality of by-products is difficult to control, especially corn!
