At present, there are two major culprits in rural farmers. One is that feed is in short supply, and the cost of breeding cannot be reduced. Second, many wastes that can be used for feed are not well used, causing great waste. If these wastes can be collected for reasonable and simple processing, they can be converted into livestock and poultry feed. This will not only expand the source of feed, reduce the cost of farming, increase economic efficiency, but also reduce the cost of waste transport and reduce environmental pollution. 1. Bacterial Feed When artificial cultivation of edible fungi is performed, there can be 60 kg of bacillary dysentery per 100 kg of culture material, which is a good feed for pigs. Its preparation method is: first remove the moldy material in the fungus, and use the thick and thick white mushroom and the thick cake, and then crush it after drying. Before feeding, add 40 kg of rice bran per 100 kg of bacillary dysentery, mix well with appropriate amount of water, and put it into the tank for fermentation for 1 to 2 days. When there is a fragrance, you can feed it. 2. Livestock feed The feces of chickens, cattle and sheep are rich in organic and inorganic nutrients. Collect the feces of a cow for 1 day and add 15 kg of bran, 2.5 kg of wheat flour and 3.5 kg of distiller's yeast. Dry and semi-wet, packed in a cylinder or in a plastic bag, sealed and sealed at a temperature of 26°C for 1 to 2 days, yellow and slightly scented, mixed with 35 kg of feed, available for 700 Only ~800 chickens were allowed to eat for 1 day. Collect 350 to 400 chickens for 1 day to excrete feces. Add 2.5 kg each of bran and wheat flour to ferment. Also use the above method to ferment. When the chicken excrement is yellow-green and odorless, add 25 kg of feed grain and 15 green fodders. In kg, 30 to 40 pigs can be fed for 1 day. It is also possible to dry or dehydrate the chicken, cattle and sheep droppings. Rabbit feces contains 18.7% of crude protein, 4.3% of fat, and 2% of ash, which is a good feed for pigs. Its preparation method: 1 After the rabbit manure is dried and crushed, it is mixed into the feed and fed in proportion. 2 soak dried or dehydrated rabbit feces with water, soften, and feed them into feed. 3 Fresh rabbit manure was fed on the same day. Piglets were fed 0 kg to 2 kg each day, 0.3 kg on shelf pigs and 0.5 kg on large pigs. 3. Corncob corn cob contains 2.2% crude protein, 0.4% crude fat, and 29.7% crude fiber. It is also rich in minerals, vitamins, and trace elements. The sun dried, crushed into a powder, soaked in water, softened, according to 5% to 8% of the pig diet mixed feed. 4. Sunflower Residues Feed sunflower residues include disk, straw, seed husks, etc., and flour can be used as feed. When the feed volume accounts for 30% of the pig diet, the average daily gain is 0.4 kg. The use of 2 kg of sunflower residue instead of 1 kg of powdered material for feeding dairy cows has the same milk production per day, but the milk fat content is significantly increased. 5. Pericarp, shell, kernel feed Most skins, shells, and kernels can be used to feed livestock and poultry. For example, watermelon rind can be chopped and fed to pigs, chickens, geese, and ducks. The daily feed volume can account for 30%. The role is conducive to the normal growth of livestock and poultry, and citrus, orange and other skin dried crushed, not only is a good feed, but also a good medicine for fire evacuation. 6. Coal fly ash Coal ash contains 1% of calcium, 1.8% of potassium, 0.06% of phosphorus, 0.27% of sodium, 0.16% of magnesium, 2% of iron, and 2% of copper, zinc, manganese, etc. These are all necessary for the growth of livestock and poultry. Minerals. The fully-burned coal ash is crushed and sieved, and mixed in the feed at a ratio of 1% to 3% of the diet of the livestock and poultry or sprinkled in the tank to allow pigs and chickens to feed freely. 7. The peat of the peat feed blisters and meadows is rich in organic matter and is a good feed for livestock and poultry. Method: Peat containing more humic acid is dried and crushed, and added to other feeds at a 20% ratio. 8. Tobacco Stem Feed stems are rich in protein, fat and trace elements. Method: Cut the stems, dry them, and pulverize them. Add 10% to the feed. 9. Sawdust The steam and catalyst are used to treat the sawdust with high pressure to hydrolyze the cellulose to starch and sugar to feed. It can also be made by fermentation method. It can take 70 kg of sawdust without impurities, 30 kg of rice bran or bran, 0.2 kg of yeast dough, 0.2 kg of salt, and 50 kg to 60 kg of water. Mix well until it is semi-wet and mix it. Packed in wooden barrels or concrete pools for compaction, the top is tightly capped, and after fermentation for 1 to 2 days, when the raw material is loosely flavored or sweet and salty, it can be fed, according to 20% to 30% of the pig's diet. 20% of chicken and duck diets were fed into the feed. 10. Heterozygosity Heterophagous bones are rich in calcium and phosphorus, and are high quality mineral feed for livestock and poultry. Put various kinds of animal bones into the pot, add vegetation gray water (formulated with 10 kg plus 2.5 kg of plant ash), cook, and cook the oil and bone glue while cooking, and continuously add the plant gray water until there is no oil on the water surface. After the bones are dried out, they are crushed and sifted to make up the facial bone powder. The bone can also be placed in a steamer for cooking at home and continuously steamed for 6 hours to 12 hours. If the pressure cooker is used, it takes only 2 hours to 4 hours to release the bone glue and fat, and then the bone is dried and crushed. You can. When used according to the needs of livestock and poultry added to the feed and mix feeding. 11. Pine leaf feed Pine leaf contains protein, fat, and a variety of vitamins and various trace elements. Method: The collected pine needles are removed and put into a pot, heated and dried, then crushed, and fed at a rate of 5% with other feeds. In addition, by-products such as bean curd slag and powdered slag are rich in calcium and phosphorus and various functional fibers. They are all useful materials that can be used directly for refining and roughage without processing. China Agricultural Network Editor
