Feeding cattle in the winter

1, cut the rough material, washed, ammoniated

In order for the cattle to digest and use the coarse material, the entire coarse material should be cut to 8-10 cm to reduce the energy consumption of cattle due to chewing coarse material. The high content of oxalate and silicon in coarse materials (especially straw) is the main factor that causes urinary calculi in cattle. To prevent cattle from developing urinary tract stones, the coarse material should be washed before feeding to reduce the content of oxalate and silicon in the coarse material. Coarse feed cows are undernourished and can subject the raw material to ammoniation. The rough amination treatment method is as follows: The ammoxidation tank is repaired in advance, and the rough material is cut short. For each 50 kg short cut coarse material, mix 6-10% urea solution 25 kg, and then put it into the chlorination tank, layer by layer. Practical, pool mouth sealed with plastic film. After a period of 1-1.5 months of ammoniated fermentation, the coarse material is put into ammonia and can be used for feeding cattle.

2, add a certain amount of calcium, phosphorus, salt and trace elements additives

The amount of calcium required for normal growth and development of cattle is 0.4% of feed, and the amount of phosphorus needed is 0.3% of feed. There is a lack of winter greens, and calcium deficiency is often seen in cows fed only with coarse material. Therefore, for cattle that feed coarse material, it is necessary to supplement 10 grams of calcium, 5 grams of phosphorus, and 30-50 grams of salt each day, and appropriate amount of complex trace element additives.

3, feeding security

Feeding cattle in winter, it is necessary to feed cattle with 40% of corn, 20% of soybeans, 10% of scraps, 10% of barley, 10% of soybean cake, and 10% of bran. After soaking in warm water, it is used to feed cows. Feed 0.5-2 kg of mixed concentrate daily. For young cattle, pregnant cows and thin cattle should be properly increased feed volume.
