First, don't buy fishmeal yourself. Fishmeal is a very high quality protein material, rich in lysine, and an indispensable raw material in piglet feed. But why not let the farms buy them themselves? According to industry insiders, after surveying feed manufacturers and feed distributors, they found that almost no real fishmeal was seen on the market. So if you want to make your own ingredients, choose 5% premix, because 5% of the premix has been added to the fishmeal, of course, the premix also buys the products of the big brand feed enterprises. Second, choose the cardamom carefully. Soybean meal is the most important protein material in pig feed. The current price is getting higher and higher, so there are more and more inferior products. Soybean meal without adulteration is very rare. Therefore, it is recommended that the farm should be tested when purchasing soybean meal in large quantities. Third, buy feeds and don't just compare protein content. Protein is important, but not the higher the better, now there is "protein essence" on the market to cope with common tests, the crude protein content is high, such as urea, can increase the crude protein, cattle can be used, but pigs can not. "Protein" does not contain any vitamins, amino acids, and even can not be used. Choosing a feed must choose a well-known brand, they will not use their inferior raw materials to lick their own brands. Fourth, don't think that pig manure is dry and black. Many pig farms see the feed through pig manure. It is necessary to use the pig manure to dry and blacken. Many feed enterprises specialize in investing in it, adding high copper to achieve this goal. However, the pig manure in foreign pig farms is not like that. People do not use such high copper, which is not good for pigs and is more unfavorable to the environment. Fifth, the tank is to be fed under the automatic feeding box. Many pig farms use automatic feeding boxes. Most of the tanks have small tanks. The pigs have to put their heads in the boxes to eat them. This makes pigs very suffocating and easily cause respiratory diseases. If there is a tray under the automatic chute, it will be much better if the material leaks into the pan (slot) and then the pig is eaten.
