(1) Sodium (salt) salt can be made into salt water according to a certain ratio, generally 1:5-10, directly added to the feed, and evenly mixed to feed. It can also be placed in cereal feed. The amount of salt must be accurate and prevent excessive amounts. (2) Calcium and phosphorus balanced feed can directly add bone powder and ashes to the feed according to the amount, but can not be mixed with vitamin B, vitamin C and yeast. Otherwise, the active ingredients will be destroyed. After the above feed is prepared, it can be minced and conditioned at the same time. In large-scale farms, animal feed is first introduced, followed by plant feed. If the group is small and the amount of feed is small, the various feeds can be mixed and ground. Then add milk, vitamins, saline, etc., and stir well. A well-mixed mixed feed should be quickly distributed to each group for feeding.
