Cut down the rough part of the lower part of the straw should be cut to make, the top of the straw can be cut into 3-4 cm long grass, the best feeding effect. Daily intake increased by about 2% over hay.
After comminution of the comminuted straw, feeding with concentrate feed can increase feed intake and improve digestibility. Crushing the roughage can speed up feed emptying and increase feed intake. However, comminution of roughage or cutting of roughage is very short. The chewing and ruminating time, the amount of saliva secretion, the time the feed stays in the rumen, the digestibility of roughage, the ratio of acetic acid to propionic acid in the rumen, and the pH and milk fat percentage are all reduced. Not conducive to cow health and milk production. Long roughage can maintain the structure of the rumen content and stimulate rumen motility, rumination, and salivation. Therefore, at least 1/3 of the long roughage (2-5 cm) should be used in the diet.
Soak the shredded roughage or clams with water or soaked in 0.2% saline. After 24 hours, soften the quality. Mix with the mixture and bran to change the palatability and increase the feed intake.
The alkaline treatment is to cut the straw into 3-4 centimeters in length, spray the 1.6% sodium hydroxide solution evenly on the straw, make it moist, put it aside for a few days, and take out the feed directly.
The calcification method uses 1% quick lime or 3% milk of slaked lime to soak the straw, about 8-10 kilograms of straw per 100 kilograms of lime milk, and the cow is fed directly after 12-24 hours. Or take 100kg of chopped straw, add 3kg of quicklime or 4kg of cooked lime, mix 0.5-1.0kg of salt and 200-250kg of water, mix it, and place it on the ground or on the board for 24-36 hours, directly Feed cattle.
Ammonia treatment is an anhydrous ammonia treatment. The moisture content of the straw is adjusted to 30% to 40%, and a plastic pipe is added at a height of 0.5 m to pass ammonia water. Grasshoppers are sealed with a 0.5 mm thick plastic film, and the time varies with the ambient temperature. When the temperature is 2°C, seal it for 2-4 weeks. Dried after opening and fed with ammonia disappeared. The second is ammonia treatment. When the short straw is piled in the pit (cellar), 3% concentrated ammonia is uniformly sprayed into the pit in a 1:1 ratio of straw weight. After the tank is filled, the membrane is covered and sealed. The sealing time is determined by the ambient temperature, 8 weeks for less than 5°C, 4-8 weeks for 5-15°C, 1-4 weeks for 15-30°C, and 1 week for temperatures above 30°C. Then open the cellar to dry the straw and feed it. Feed ammoniation treatment can increase the protein content of roughage by 4%-6%, and increase feed intake by 16%-60% per head per day, and increase the digestibility of straw organic matter. The disadvantage is the large amount of ammonia lost, and about 2/3 ammonia slip after opening the pit.
Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
