Fragmentation
Straw, yam, grass, hay, etc., should be chopped and fed to livestock. When the pigs' vegetables are cut into 1 cm to 2 cm, they can achieve the effect of “three-inch cutting and three-knife cutting without any material.â€
Powdering
Hay, grains and other feed must be ground and then fed to help digestion. The degree of chalking should be based on feed and livestock species. The feed for pigs can be crushed to about 1 mm to 2 mm in thickness, and the chicken feed should be ground to a coarse powder.
Pulp
Sweet potatoes, cassava, beans, and cakes, etc., as feed, should be soaked and fed after slurried, which is beneficial to digestion, improves feed effect, and can also remove feedstuffs such as hydrocyanic acid and other toxins.
Budding
When the grain feed germinates and grows to 10 cm, the content of vitamins, especially carotene and riboflavin, is extremely rich, and it is one of the good sources of vitamins for livestock and young livestock.
weathering
After harvesting fresh green feed, living cells are still oxidizing and depleting nutrients in the feed, and the microorganisms multiply rapidly to degenerate. Therefore, fresh green feed should be dried in time, but it should not be exposed to sunlight to avoid vitamin loss.
soften
Corn, wheat, sorghum and bean cake, etc., should be soaked with light salt water before feeding, so that it can be softened and then fed, not only to save feed, but also easy to digest, livestock and poultry like to eat.
Heating
The legume feeds should be processed and brewed by steaming to destroy the antitrypsin in the beans and increase the effective methionine and cystine in the bean protein, which can increase the biological value of the feed and increase the palatability. The cooking time is about 50 minutes.
Storage
That is, the green material is stored in various pits, pools, tanks and non-toxic polyethylene plastic bags. Cellar storage can be fermented under anaerobic conditions to generate lactic acid to protect the nutrient of green material and improve the utilization rate and digestibility. The plastic bag silage is not mildewed for long-term storage, rich nutrition, and good palatability.
Alkalization
The crude material was alkalized with 1% quick lime milk. The water can be immersed in the feed, which is immersed for 24 hours and then fed without washing with water. After the feed is alkalized, the livestock can fully digest and absorb the nutrients and supplement calcium, magnesium, potassium, sodium and other trace elements, and can also increase the intake of food. Quantity and digestibility.
acidification
The use of a suitable amount of phosphoric acid to mix in the green material and then add a little Glauber's salt can increase the sulfur content of the feed, help non-protein compounds to form bacterial proteins, enhance the vitality of lactic acid bacteria, and thus increase the nutritional value.
Ammoniation
The raw material is first cut into 2 cm to 3 cm, and 1 kg of ammonia 12 kg to 15 kg is used per 100 kg of coarse material. The layers are compacted, sprayed and sealed layer by layer. Ammoxidation can be performed at room temperature 25°C to 30°C for 7 days. Full aeration in Kaifeng, so that the residual ammonia volatilization and then fed, the nutritional value of crude material after ammoniation increased significantly, such as straw containing crude protein than untreated straw 40% to 80%.
Hydroformylation
Treating feed, silage, and hay with formaldehyde can increase their nutritional value. For example, the mixed calamine and leguminous mixed silage with 0.12% formaldehyde and 0.14% acetic acid have less heat loss, almost completely stop the destruction of protein during silage, and increase the nutrition of insoluble protein in silage. ingredient.
Saccharification
Add 100 kg of crude material to the prepared enzyme (Qiju) from 2 kg to 5 kg, add 100 kg of water and stir into the cylinder to seal it, raise the temperature to about 40°C, and then compact and seal the feed. Days to 4 days can be fed. After the feed is saccharified, it has the characteristics of acid, sweet, fragrant, soft and cooked, excellent palatability, and the livestock and poultry love to eat and feed well.
