Bran bran is a high-phosphorus, low-calcium diet with more than 4 times the amount of calcium in the diet. In the treatment of osteoporosis or cartilage disorders due to calcium and phosphorus disorders, wheat bran should be stopped.
Soybeans contain more calcium and magnesium and other elements, which can be combined with tetracycline drugs (such as tetracycline, oxytetracycline, doxycycline, etc.) to form insoluble, hard-to-absorbent conjugates, thereby reducing the efficacy of these antibiotics. During the course of the prevention and treatment with these antibiotics, feeds for beans and cakes should be fed less or stopped.

Sulfonamide feed additives have a killing effect on the effective bacteria in active bacteria preparations. When using Brucella porcine type 2 vaccine, promoting bacteria, and lactase, use of such feed additives should be stopped.
