Feeds for alfalfa include animal feeds, vegetable feeds, and added feeds. The supply and composition of feed have a great influence on the health, breeding and fur quality of earthworms. Therefore, the breeder must rationally formulate and supply feed according to their biological characteristics and nutritional needs in different biological periods. To implement scientific breeding, one must understand the effects of feed nutrients on earthworms in order to properly and properly formulate and process feeds so as to obtain the best economic benefits with the minimum feed consumption. Therefore, the modulation of feed processing is very important. First, feed processing (a) fish, meat feed processing. Fresh sea miscellaneous fish, meat, liver, kidney, heart and blood of healthy animals, remove large chunks of fat, fully wash away dirt and impurities, crushed and fed. The fish and meat feed that are of poor quality but can also be used must first be thoroughly washed with fresh water, then sterilized with 0.05% potassium permanganate solution for 5 to 10 minutes, and then washed with fresh water before minced and fed. Seriously corrupted fish and meat are prohibited from processing and utilization. The intestines, spleen, lungs, and other impurities of freshwater fish and poultry must be cooked. Cysticerus pork (pox pork) can be processed and used after high-pressure cooking or fully cooked and fat removed. Fishmeal and meat and bone meal should be soaked for 3-4 hours. Change the water after 2-3 times and remove excess salt before mixing with other feeds. Blood meal and liver dregs powder are used after cooking. Silkworm cocoons must be fully soaked, and alkalis should be minced after cooking. (b) Processing of dairy and egg feeds. Fresh milk, goat's milk, etc. must be disinfected prior to feeding. It is usually heated in a pan to 70-80°C for 15 minutes. After cooling, it is fed into the feed. The milk powder was dissolved and diluted with warm water in a ratio of 1:7-8 and fed into the mixed feed. Eggs are mainly fresh eggs, lean eggs, wool eggs, etc., must be cooked and fed. (3) Processing of fruit and vegetable feedstuffs. The roots and rots are removed from the vegetables, the dirt and impurities are washed away, and the harmful pesticides or fertilizers are rinsed, then minced and fed. Spinach has a laxative effect, it is best to use hot water and then mixed with other feed feed. Cut away the rotten parts of fruit, wash the soil and harmful pesticides and grind them to feed them. Tomatoes, zucchini, and leafy vegetables have a good effect. (4) Processing of grain feed. Seeds of crops must be crushed to fine powder, and it is advisable to mix and match several types of grains. Cereal feed must be fully cooked and utilized. If you are half-cooked, you may easily cause gastrointestinal dilatation or enteritis after eating, which is not good for your health. The processing method is steaming to make a head or boiled into a porridge, or it can be fried or puffed with a pan. Soybean can be made into bean juice. The method is to soak the soybeans for 10-12 hours and then pulverize them (available in a pulper) to boil them. After the coarse cloth is filtered, the bean juice is prepared. It can also be used to crush the soybeans into fine flour, boiled with 1 to 8 kg of water and 1 to 10 litres of water. It can be used without filtration. The hot bean milk made after cooling is mixed with other feeds to feed oysters. (e) Processing of vitamin feeds. Water-soluble vitamins include vitamin B1, vitamin B2, and vitamin C. They can be dissolved in warm water below 40°C, and then fed into the feed before feeding. Fat-soluble vitamins such as vitamin E and vitamin AD have higher concentrations. They can be diluted with soybean oil and soaked in feed before feeding. Medicinal yeast and feed yeast can be directly added to feed before feeding. (6) Processing of inorganic salt feed. Salt must be accurately weighed and fully salted and then added to the mixed feed. Mix it thoroughly. Note that it is not allowed to use the salt directly in the feed. Bone meal and bone ash can be directly added to the feed in an amount, but be careful not to mix it with vitamin B1, vitamin C and yeast in order to prevent the active ingredient from being destroyed. Second, the preparation of feed Through the above-mentioned processed feed, we must strictly check the weighing scale, minced and mixed. In small-scale breeding farms, several kinds of feeds can be mixed together. In large-scale breeding farms, fish, meat feed, livestock and poultry by-products can be firstly twisted, and then feeds such as cereals and vegetables can be ground. Finally, water, vitamins, or inorganic salts can be added. Feeds, feed evenly after mixing. During the process of feed processing and modulation, it is necessary to pay attention to: (1) It is strictly regulated according to the type and quantity of feed specified in the feed list, and cannot be arbitrarily changed. (2) The modulation speed is fast, and the processing time is shortened as much as possible. Each modulation should be completed before food intake, and must not be advanced so as to avoid loss of nutrients due to excessive time. (3) The ingredients are accurate, the ingredients are even and the concentration is moderate. The concentration during the breeding season should be thinner, and the non-breeding period should be thicker. (4) Feeds such as vitamins, milk, and yeast must be added before feeding, and should be mixed evenly to prevent premature mixing into the feed and cause oxidative damage or inconsequential food intake. (5) Feeds with large temperature difference between hot and cold, raw and cooked should be placed separately when they are stored, and they should be stirred together when the temperature is close. (6) The thawed feed should not be stored in the spice room for more than 24 hours to prevent the feed from deteriorating over time. (7) The feed and water must be hygienic, must not use moldy and deteriorating feed, and the water should be clean and sanitary. (8) The feed mixing room should be kept clean and hygienic. The used equipment and tools used for processing feed should be cleaned in time and regularly disinfected with potassium permanganate or alkaline water.
