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:
One is fresh feed. The collected fresh soybean leaves were removed to remove impurities and foreign matter. After being chopped, they were directly mixed into the pig's diet. The amount of feed was about 30% of the diet. For pigs under 30 kg, chopped soybean leaves can be cooked in a pot and then fed into the pig's diet.
The second is silage. Soybean leaves have low sugar content and rich protein content. Suitable for semi-dry silage. The method is: the soybean leaves are air-dried to about 50% moisture content, and then rough cut with a knife, and then into the silo, lack or plastic silage bags, compaction seal. When the pigs need to be fed, they are taken out of the diet of the pigs and the amount of feed is about 25% of the diet.
The third is smashing. Soybean leaves are placed in a dry and ventilated place, dried to a moisture content of about 30%, then dried in the sun, dried quickly or placed in a drying room to reduce the moisture content to below 10%, and then pulverized into soybeans using a pulverizer. Leaf powder. This soybean leaf powder can be stored for a long time. When used to feed pigs, they can be directly mixed into the pig's diet. The amount of feed can account for 20% to 40% of the diet.
For soybean leaves used for pig feed, the best period for collection is the soybean wax ripening period. At this time, not only is the soybean leaf greener, it has good nutrition, and its crude fiber content is small, and it will not affect the yield and quality of soybeans.
