It is very beneficial to improve the utilization rate of feed for beef cattle. Let's talk about the modulation method of beef cattle commonly used feed for reference.
1. Crushing All kinds of concentrates should be pulverized before feeding. The diameter of the pellets after processing is 1 mm - 2 mm.
2. Short cut Straw and other roughage should be cut short before feeding, and the roots, tubers and other juicy materials should be cleaned before breaking.
3. Salted straw and corn stalks are crushed into silk flocculent, and put into the fermentation tank (or large tank), adding 1.2 kg - 2 kg of salt per 200 kg of raw materials, 65 kg - 75 kg of water, mixing well without cover The toxic plastic film, after rising from 24 hours to 48 hours, reaches a temperature of 40 ° C, and then cools down, then seals with a plastic cloth, covers the straw curtain, and can be fed after 24 hours.
4. Alkaline chopped straw with 1% quicklime water (ie 1 kg of lime plus 50 kg of water, remove the precipitated slag, then add 50 kg of water), stir well, soak 35 kg of short Raw Material, After 10 minutes, remove the lime water and store it in a container. It can be taken after one day.
5. Ammonia, chopped corn stalks, etc., add 5 kg of warm water containing 100 g to 150 g of urea per 25 kg, soak for 6 hours to 20 hours at 15 °C, mix with appropriate amount of concentrate after ammonia removal. Hey.
6. Silage Silage materials should contain more sugar and more than 25% dry matter, mainly planted gramineous plants and wild plants. Gramineous wild pastures are harvested before seeding, and it is recommended to promote the storage of grasses and grasses, and the grasses and legumes can be mixed. All kinds of roots, stems and leaves with more water content as silage raw materials should be air-dried or mixed with 10%-20% bran feed and then silaged. Silage can be stored in silage, flat or plastic bags. The size of silage can be determined according to the number of beef cattle and the annual reserve. Silage can be 500 kg-600 kg per cubic meter of silage.
Silage corn is harvested during the ripening period, and the dry matter content of the whole plant with spiked corn is between 25% and 30%. Harvest using a silage harvester or a feed chopper to cut into 2 cm - 3 cm. When the raw material is poured into the silo, spread it evenly. When it is filled, it should be covered with a plastic film of sunscreen to reduce the mildew. After 30 days of storage, it can be used for feeding. After the opening, it should be taken continuously to prevent secondary fermentation.
