In order to make everyone master the mechanism of urea feeding cattle and the specific feeding method to better play the role of urea in cattle production, the relevant questions are answered as follows: First, why can urea be used to feed cattle? According to the digestive characteristics of ruminants, after the rumen has a well-developed rumen function (3 to 4 months of age, and ciliates begin to appear in the rumen), microbes in the cow's rumen can use the nitrogen source provided by the non-protein nitrogenous compounds in the feed. protein. Urea is a non-protein nitrogenous compound, is a chemical product, can be mass-produced, the cost is very low, urea nitrogen content is high, generally 46%; urea synthesis through the rumen in the rumen digestion of bacterial protein synthesis, Can replace part of the protein feed. 1.Forage: The crude forage of wheat straw, dry corn stalk or green corn stalk, and mountain hay, and the corn and bran of fine material, the crude protein content is below 12%. 2. Urea fed amount: 20-30 grams of urea per 100 kilograms of body weight per cow per day. 3.

The daily dose is fed in multiple times. 1. Urea can only be used in adult cows, because the rumen of lactating calves is not yet fully developed, microbial flora is not normal, it is not appropriate to feed urea. 2. The urea should be mixed with the dry material and then mixed in the crushed grass to feed, do not use water-soluble Beverage; the amount is best divided into multiple feedings, avoid feeding once. 3. The amount of urea can not be too large, otherwise it will cause poisoning. 4. After feeding urea, you can't drink water immediately, at least half an hour before drinking.
