Tofu residue can be used as organic fertilizer. Organic fertilizers mainly include human excrement, livestock and poultry manure and various cakes, such as soybean cake, sesame paste residue, cottonseed cake, etc. They are rich in nitrogen, phosphorus, potassium and trace elements.

Nitrogen fertilizer can promote the luxuriant branches and leaves of flowers; phosphorus fertilizer, mainly derived from bone meal, can promote bright flower colors and fruit enlargement. Potassium fertilizer is a fertilizer based on plant ash, which can promote the growth of flower branches and root systems. The application of organic fertilizer must be fermented. Raw fertilizer can easily damage the root system of flowers.

Characteristics of tofu dregs:

1. It must be cooked before feeding. Raw tofu residue contains antitrypsin, which can hinder the digestion and absorption of soy protein by trypsin in pigs and affect the growth and development of pigs. Therefore, before feeding, it should be heated for 10 to 15 minutes to decompose and destroy the antitrypsin, so that the absorption and utilization rate of protein can be improved.

2. The amount used must be mastered. The crude protein content in tofu residue is slightly lower than that of soybean cake and soybean meal, and the quality is relatively poor. Therefore, it should be fed with other feeds to meet the growth needs of pigs. If you feed tofu dregs alone for a long time, it will easily cause loss of appetite and indigestion in pigs, lead to infertility or abortion of sows, and reduce the survival rate of piglets.

3. Sufficient mineral elements and green feed should be combined with actual conditions to promote the healthy growth of pigs. The quality of tofu dregs must be guaranteed. Tofu residue contains a lot of water and is prone to spoilage. Pigs eating spoiled tofu residue can cause enteritis, diarrhea and other diseases, and in severe cases, death. Therefore, spoiled tofu residue cannot be fed to pigs.
