How to ferment pigweed, wheat straw, straw, feed sheep, and cattle, the effect is good

Ferment with warm water with water and cornmeal.

Steps: 1. Silage crop straw should be harvested in a timely manner: when the corn straw is mature and the corn straw is only the lower l-2 leaves are yellow, the silage should be harvested immediately.

2. Chop short: Use a forage shredder to chop the straw.

3. Filling: The short green fodder should be filled in time. In order to strengthen the seal and prevent air leakage and water penetration, the silage cellar can be filled with plastic film.

When filling green fodder, it should be loaded layer by layer. Each layer is 15-20 cm thick, add EM stock solution, and continue to fill after stepping on it, especially the four corners and wall parts should be firm. Load until it is 1-1 5 meters above the cellar mouth, and then compact.

The standard for checking whether its compactness is appropriate is that after the completion of fermentation, the feed should not sink to a depth of 10.

4. Sealing: Tightly sealing the cellar and preventing water and air leakage is an important part of preparing high-quality silage. When the straw is stored at the mouth of the cellar more than 60 cm, it can be capped and capped.

You can first cover a layer of cut straw or soft grass, cover with plastic film, and then cover it with soil to make a steamed bun shape to facilitate drainage.

5. Management of silage cellar: dig a drainage ditch at a distance of l meters from the cellar to prevent rainwater from infiltrating into the cellar. It should be checked frequently. If there is a crack in the roof of the cellar, it should be covered with soil and compacted in time to prevent the foundation from noisy and breathable and rainwater.

Of course you can, straw feed method:

One. Physics Theory.

1) Short and crushing method: It can reduce the volume, increase the contact area of rumen microorganisms on straw, and increase the amount of food and the speed of passing through the rumen. Usually the length of the straw for cattle feeding is 3 4 cm, and the length of the straw for sheep is 2 3 cm.

Short grinding is effective for corn stover and cob, increasing feed intake by 25% and feed efficiency by 35% compared to unprocessed corn stover. However, any material should not be crushed too fine (1 2 cm of coarse material for cattle), after the cattle eat a large amount of fine feed, it will affect its rumen function and rumination, or it has not been fully fermented by microorganisms through the rumen. If the straw can be crushed and then pressed into pellets to feed cattle and sheep, its dry matter intake can be increased by 50%.

And the feed effect is greatly improved. If the straw pellet is mixed with concentrate, the effect is better. It can also be sprinkled with light salt water (salt water concentration to increase appetite.

It can also be kneaded into silk strips with a straw kneading machine.

2) Pelletizing: Pellets with a diameter of 4 5 mm and a length of 10 15 mm are made with a feed compressor.

3) Puffing: puffing with an extruder.

Second, chemical treatment methods In the past century, great progress has been made in improving the nutritional value of straw feed by chemical treatment methods, and some chemical treatment methods have been widely used in production. At present, alkaline compounds such as ammonia, urea, sodium hydroxide, lime and other alkaline compounds are mainly used in the production to treat the straw, so that it can open the alkali-unstable ester bonds between cellulose, hemicellulose and lignin, so that the cellulose swells, change the swelling force and permeability of lignin and cellulose in the straw, and then make the enzyme have more contact area with the substrate to be decomposed, so that the rumen juice is easy to penetrate, and the substrate is more easily decomposed by the enzyme, and volatile fatty acids such as acetic acid, propionic acid, butyric acid are formed, which are used as energy after absorption. At the same time, it can release crude protein in the cell, so as to improve palatability, increase feed intake, and improve the digestibility and utilization rate of nutrients in straw.

Ammoniation treatment method 1The advantages of ammoniation treatment: First, it can improve the nutritional value of straw feed.

Among them, the digestibility of organic matter can be increased by 8 12%, or even higher; The nitrogen content of straw can be increased, which can reduce the supply of crude protein. The treated straw is basically equivalent to medium hay and can be used as the main roughage for cattle and sheep. Second, it can increase feed intake by 20%.

Third, it can make the orange stem with high water content directly stored, so as to avoid the loss of nutrients caused by sunning. Fourth, it can kill weed seeds mixed in straw. Fifth, the cost is low, the method is simple, and it is easy to promote.

Feeding livestock with ammoniated straw promotes weight gain and reduces feed costs. 2.To perform a good ammoniation treatment, it is first necessary to decide what kind of ammoniating agent to use and how much to do

At present, the main ammoniating agents used in China are urea, ammonia, liquid ammonia and carbon ammonia. Among them, urea and liquid ammonia have the best treatment effect. The urea method is the most commonly used.
