1. When the chickens have stress response (such as vaccination, transfer, etc.), should add 10% of VA, VE, VD, VC.
2. When the chicken has chronic diseases (such as chronic respiratory diseases), it should also add 10% of VA, VE, VC.
3. Adding more 5% VA to the broiler feed can increase the feed remuneration and help to speed up the chicken's growth and development; for chicks, the lower the feed VA content, the higher the incidence of coccidiosis in chickens. Therefore, when chickens have coccidiosis, 20% of VA, VK, and VC should be added to the feed.

5. In the hot summer season, chicken feed should be supplemented with 2% VC, which can improve chicken disease resistance, reduce chicken body temperature, improve production performance and reduce stress response.
6. During the peak period of egg production, layers should be added with 2% of VB2. In order to increase the hardness of egg shells, 2% of VA and 2% of calcium should be added in addition to 2% of calcium in feed. .
7. When flea and coccidiosis occur in chickens, multi-dimensional multivitamins should be added to the feed.
8. When a certain vitamin deficiency occurs in the flock, the amount of vitamins in the feed should be three times that of the constant.
