Soybean leaves are rich in crude protein and crude fat, but also rich in calcium and phosphorus. Therefore, the use of soybean leaves to feed pigs is an effective way to supplement protein in the absence of protein feed. There are three specific feeding methods:
Freshly harvested fresh soybean leaves were chopped and directly mixed into the pig's diet, which accounted for about 30% of the diet. For piglets weighing less than 30 kg, chopped soybean leaves can be cooked in pots and then fed into the pig's diet.
Silage soybean leaves are low in sugar content and rich in protein, suitable for semi-dry silage. Soybean leaves were air-dried to a moisture content of 50% and then roughly chopped with a knife and placed in silages, tanks or plastic silages to compact the seals. When it is necessary to feed the pig, remove the silaged soybean leaf and mix it with the pig diet, which is about 25% of the diet.
Soybean leaves are placed in a dry, well-ventilated place, dried to a moisture content of 30%, then dried in the sun, dried quickly, or placed in a drying room to dry, so that the moisture is reduced to 10% or less, and then pulverized into powder by a pulverizer. . This soybean leaf powder can be stored for a long period of time. When it is used to feed pigs, it can be directly mixed into the pig diet. The feed amount can account for 20% to 40% of the diet.
