All feeds that have spoiled or come from infected areas must not be used. Second, washing: meat, fish, livestock and poultry by-products and fruit and vegetable feed, must be washed with water before use to remove dirt and mud. Mild loss or suspicious animal feed must first be disinfected with 0.05%-0.1% potassium permanganate for 5-10 minutes and then washed with clean water. Third, soaking: fish meal, bone meal should be soaked with water for 4-6 hours (change the water 2-3 times), light-dry fish soaked for 12 hours (for water 2-3 times), salty fish soak for 1-2 days (every day Water 2-3 times), cocoon powder, blood meal and liver dregs powder, and dried fish with poor quality, dry stomach, etc., in addition to fully immersed, but also for cooking. Fourth, cooking: poor quality meat, fish and livestock and poultry viscera, after disinfection by potassium permanganate, but also cook cooked; freshwater fish to steam for 2 hours; pox pork to fat must be high temperature and pressure treatment; grain flour Add water to make the steamed bread and make it fully steamed. Each kilogram of cereal flour can be cooked and made into 1.8~2 kilograms of steamed bread. It can also be fried into noodles and then boiled with boiling water to make a congee of sticky cans. Fresh cow and goat's milk should be heated and sterilized. Milk powder is diluted with boiled water; poultry eggs are cooked; blood meal should be boiled before feeding, and then mixed into the feed; spinach and bok choy washed in boiling water after boiling to remove bitter and astringent taste. All heat-treated feed must be cooled before mixing. V. Weighing: Weighing and weighing the amount of feed products as stipulated in the fodder matching sheet. 6.

Modulation: After the feeds processed in the previous process, they are all concentrated in the mixing ponds, and then the dairy products, water (or soya milk) and other supplementary feeds are added as required. Drug yeast or feed yeast can be added directly. Baker's yeast or brewer's yeast needs to add a small amount of water, heated to 70-80° C., and kept for 10-15 minutes. It can also be steamed together with cereal flour. Bone meal can be directly added to the feed in an amount and cannot be fed with yeast, VB1, etc.; drugs and vitamins should be put in last, and should be evenly mixed. The dilute consistency of the feed preparation should be appropriate, and the feed for the lactating mother and the newly weaned cubs can be slightly diluted.
