What are bean cakes for? What is the bean cake used for

Bean cake. Soybean cake is a by-product of soybeans (mainly soybeans and black beans) after oil extraction, and has the highest nutritional value among various plants. Generally speaking, the digestibility of each kilogram of soybean cake in dry matter is more than 3000 kcal, the crude protein content is more than 40%, and the biological value of protein is higher than that of any kind of cake feed.

Among them, the content of lysine, which is necessary for livestock and poultry, is 10 times higher than that of corn. Although the nutritional value of soybean cake is very high, if it cannot be used scientifically and reasonably as feed, it cannot play a role with high nutritional value. Therefore, when using soybean cake as feed, we must strictly pay attention to the four taboos:

1. Avoid excessive dosage.

Soybean cake is a high-quality protein feed for young animals, breeding bulls, pregnant and even lactating mothers, and all kinds of livestock and poultry like to eat it very much. But the dosage should not be too much, it can account for 10% to 20% of the pig's diet, and more will cause diarrhea. Fattening pigs should not be fed more, otherwise the fat will become soft and affect the quality of the meat.

In the diet of dairy cows, it is generally possible to feed 4 kg per day, which can promote milk production. Cows overfeed it, such as making butter from their own milk, which can soften the butter. It can generally account for 20% of the chicken's diet, and if the dosage is too much, it will cause diarrhea and even gout.

2. Do not use alone.

Soybean cake contains methionine, which is necessary for livestock and poultry, and the content is higher, generally, cottonseed cake, fish meal, and alfalfa grass can be used to replace a part of the soybean cake, so that its essential amino acids can be balanced. Therefore, although crude protein is of good quality, it should not be used as a protein feed alone. Because the soybean cake still lacks microbiotic D and carotene, and the content of iron, calcium and phosphorus is not rich, it is necessary to pay attention to the supplement of vitamin AD and calcium, phosphorus and other nutrients when feeding various livestock and poultry with soybean cake.

3. Avoid raw feeding.

Raw soybean cake, especially soybean meal (a by-product of solvent immersion in oil), contains some harmful substances, such as antitrypsin, urease, hemagglutinin, saponins, goiterogenic factors, etc. Among them, antitrypsin has the greatest impact. However, most of these harmful substances are not heat-resistant, so they must be cooked to improve their nutritional value.

Generally, it is advisable to heat to 100 110, and rural areas can also use steamer heating treatment (steaming for 30 to 50 minutes after water boiling), but the heating time and temperature must be properly controlled. Excessive heating can denature the bean cake, reduce the activity of lysine and arginine, and also destroy cystine.

Fourth, avoid mildew and deterioration.

Because the soybean cake contains more fat (about 5%), it is easy to mold and deteriorate, and loses its feed value. Therefore, soybean cake should be stored in a dry, ventilated and dark place to prevent rancidity and bitterness, and reduce palatability. At the same time, to prevent the reproduction of mold, to avoid harmful substances (such as aflatoxin) poisoning of livestock and poultry, mildew can not be fed, in order to prevent poisoning.

It is the residue left after squeezing soy milk.

The method of deoiling is different. Soybean meal is deoiled by extraction, and soybean cake is prepared by deoiling by pressing.

Second, the nutritional content is different. Soybean meal is high in protein and soybean cake has a higher energy content.

From this point of view, compared with soybean cake, soybean meal has a higher protein content, which is more suitable as a poultry protein raw material to be added to feed brother. Nutrients of Slippery Soybean Meal:

1) The protein content is high, the amino acid composition is reasonable, the crude protein content is between 42%-46%, except for sulfur-containing amino acids and methionine.

In addition, other essential amino acids.

The content is very high, especially lysine.

The content is the highest (, is the highest content in the cake meal, isoleucine and tryptophan content is relatively high.

2) The methionine content is low, only that, so corn-soybean meal is the basic diet, and methionine supplementation should be added.

3) Soluble carbohydrates.

Mainly sugars, low in crude fiber and crude fat.

4) Low content of calcium, phosphorus and life-supporting chapuffin.

5) Soybean contains trypsin inhibitory factor, chymotrypsin inhibitory factor and other undesirable factors, improper handling will reduce the utilization rate of protein.

First of all, I'm not a master!

I think: of course soybean meal is better than soybean cake! Otherwise, why do the vast majority of the current feed use soybean meal instead of soybean cake!

The specific protein and amino acids are the same! Because they are all soybeans plus or scattered collapse workers to dig and close! It's just a small difference in quantity!

Also, the urease activity of soybean cake is much higher than that of soybean meal!

Soybean cake is generally used as fertilizer and feed.

Soybean cake, also known as "auspicious cake burning" is an oil cake obtained from soybean oil extraction, which can be used as feed and fertilizer. Pizhi and soybeans, mainly soybeans and black soybeans are by-products of oil extraction, and have the highest nutritional value among various plants.

Fierce rent auspicious cake is a special food in Haocheng in Guzhen County, Anhui Province, once as a tribute, hung a golden plaque, known as "the first in the world".

Soybean cake is an oil cake obtained from soybean oil extraction, which can be used as feed and fertilizer. Soybeans (mainly soybeans and black beans) are a by-product of oil extraction and have the highest nutritional value among all kinds of plants. Soybean cake is one of the main protein feeds in China, its crude protein content (more than 42%), good digestibility, high content of various essential amino acids, and rich in niacin, pantothenic acid, choline and other vitamins, is a good feed for pigs and poultry.

The residual fat in soybean cake is about 5-7%, and the residual fat in soybean meal is about 1-2%, so the effective energy value and crude protein content of the former are lower than the latter. In the same way, the amino acid content in soybean cake is also lower than that of soybean meal under the same conditions and at the same level. Soybean cake (meal) contains a variety of essential amino acids, especially rich in livestock and poultry limiting amino acids, such as lysine content is twice the nutritional requirements of growing and fattening pigs, four times the nutritional requirements of laying hens, methionine + cystine is more than double the nutritional requirements of laying hens.

Other contents such as histidine, threonine, phenylalanine, valine, etc. also exceed the nutritional requirements of livestock and poultry, so soybean cake (meal) has been widely used as a leading variety to balance the amino acid requirements of compound feed for many years.

Soybean meal is a by-product of soybean oil extraction. Tofu residue is a by-product of tofu processing. Soybean cake is a cake-like product made by drying and pressing soybean meal or tofu dregs.
