Fish meal is an animal protein feed, but also belongs to the category of energy concentrates, but because of its high protein content and good quality, the pig industry mainly uses its protein feed characteristics. In addition, the content of calcium and phosphorus in fish meal is also relatively high, which can effectively supplement the deficiency of calcium and phosphorus in feed.
1, when buying fishmeal, first test its purity. Due to the high price and high profits of fishmeal, many fishmeal are adulterated, mainly by mixing hydrolyzed feather powder, leather powder or inorganic nitrogen, and some adulterants rate as high as 70-80%. It is difficult to check the protein content of such fishmeal by conventional methods. It is best to send it to an experienced testing department or agency for testing.
2. Not all compound feeds need to add fishmeal, and they must be properly added according to actual needs, so as to save cost and increase production effect.
3, when buying fishmeal, it is based on the principle of sub-price one-by-one goods. If not, use quality guaranteed fishmeal.
