1. Take your seat according to the number. Different proportions of premix should be selected according to different kinds of livestock and poultry and different growth and development stages. Energy feed should be added accurately and stirred evenly.

2. 更换猪预混料要循序渐进。突然更换预混料畜禽不适应，影响采食和生长。使用中应逐渐增加新料用量，减少旧料用量，大约一周时间过渡到完全使用新预混料。

2. The replacement of pig premix should be done step by step. Sudden replacement of premix is not suitable for livestock and poultry, which affects feeding and growth. In use, the amount of new material should be increased gradually, and the amount of old material should be reduced, and the new premix should be fully used in about one week.

3. 要按配方配合饲料。有很多养殖户使用预混料常常凭自己的经验，随便改变配方，造成各项营养指标不能满足畜禽各期的生长需要。

6. The storage time should not be too long. If the storage time is too long, the premix will decompose and deteriorate, and the color and taste will change completely. Generally, the validity period is 3 days in summer and 6 days in other seasons. It should be stored in a well ventilated, dry, dark and cool place to avoid damage caused by moisture deterioration.
