Nutrients from corn stalks, distiller s grains, cottonseed, dried straw, alfalfa

1.Corn stover contains: dry matter, total energy megacalorie kg, digestive energy (pig) megacalorie kg, metabolic energy (chicken) megacalorie kg, crude protein, digestible crude protein (pig) negative value, crude fiber, calcium, phosphorus. Lysine, methionine, cystine.

2.Peanut vine contains: 90% dry matter, total energy kg, digestive energy (pig) kg, metabolic energy (chicken) kg, crude protein, digestible crude protein (pig), crude fiber, calcium, phosphorus.

Edible alcohol grains contain carotene, vitamin E, vitamin B1, vitamin B2, vitamin B3, vitamin B6, vitamin B11, and choline.

Cottonseed husks are fermented using a complex of bacteria consisting of major beneficial bacteria such as fibrolytic bacteria, lactic acid bacteria, and yeasts. The changes of free gossypol and the main nutrients crude protein (CP), neutral detergent fiber (NDF) and acidic detergent fiber (ADF) before and after fermentation were measured, and the number of microbial cells after fermentation was measured. The results show that:

After the fermentation of cottonseed husk, the content of free gossypol decreased, the detoxification rate increased, the CP increased, the NDF decreased, the ADF decreased, and the number of microbial cells reached G, which was significantly different from that before fermentation (P< and the nutritional value of cottonseed husk was significantly improved by this method.

Straw that is wrapped in bundles for micro-storage, due to its tightness.

Fiber drops respectively60% and, the difference was not significant, P >.

Alfalfa contains a large amount of iron, so it can be used as a supplementary food for anemia, and the B vitamins contained in alfalfa can be used for pernicious anemia

In addition, alfalfa also contains vitamin K with hemostatic effect, which is commonly used by folks for stomach disease or hemorrhoidal bleeding, and some prescriptions use it to treat stomach or hemorrhoids and intestinal bleeding.

Alfalfa also contains alfalfa and alfalfa phenol and other substances, which have the effect of relieving cough and asthma, and have a certain effect on bronchitis.

In addition, alfalfa contains crude fiber, which can promote the peristalsis of the large intestine, help the excretion of stool and toxins, and prevent constipation and bowel cancer.

Moreover, alfalfa contained in alfalfa can inhibit intestinal contraction, increase the content of thyroxine in the blood, and prevent the oxygen and anti-cancer effects of adrenaline.

<> cellulose, hemicellulose, lignin, crude protein, low molecular weight carbohydrate and inorganic salts are the main chemical components of crop straw. Among them, cellulose is the most abundant substance in the plant and the main structural component of the cell wall, with a content of 40-50% in crop straw, stable chemical properties, insoluble in dilute acid, and can be hydrolyzed into glucose under high temperature, high pressure and acidic conditions.

There are many raw materials used for the cultivation of Pleurotus eryngii and Ferulus, especially the straw of some crops is rich in nutrients, which is very suitable for the cultivation of these two mushrooms. The following introduces the nutrients of miscellaneous wood chips and some crop straws for producers' reference when batching.

Nutrient composition of miscellaneous wood chips and crop straw (%)

Generally, straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements, among which leguminous crop straw contains more nitrogen, gramineous crop straw is rich in potassium, and crop straw can provide nutrients about 13% 19% of the total nutrients of organic fertilizer, which can be said to be an important source of organic fertilizer for agricultural production. Straw returning has now become an important technical measure to increase agricultural production and income in arid and semi-arid areas.

Straw contains more water and sugar, which is a good feed raw material, especially corn straw, wheat straw, etc. For example, straw can be used as animal feed, after straw ammoniation treatment, the crude protein is increased from 3%-4% to about 8%, the digestibility of organic matter is increased by 10-20 percentage points, and contains a variety of amino acids, it can replace 30%-40% of the concentrate feed. It can also kill weed seeds and prevent mildew.

Therefore, ammoniated straw is fed to sheep, cattle, etc., and the effect is very good. Straw can also be crushed into grass bran for animal auxiliary feed.

Crop straw is a by-product in the production of food crops and cash crops, which is rich in trace elements such as (ACD), and is a resource that can be developed and comprehensively utilized.

a.Nitrogen BPotassium.

c.Iron DPhosphorus.

It is a plant, which contains the basic elements of carbon, oxygen, hydrogen, and nitrogen, in addition to a small amount of potassium, sodium, calcium, phosphorus and other trace elements.

Mainly elements such as c n p h and make up organic matter.

Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., and is a renewable biological resource with multiple uses, and straw is also a kind of roughage. It is characterized by a high crude fiber content (30%-40%) and contains lignin, etc. Although lignin cellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock.
