We collect some of the waste, and after simple processing, we can feed livestock and poultry as feed additives. Doing so can increase economic efficiency and reduce environmental pollution.
1. Eggshell: The eggshell contains 94% calcium carbonate, 1% magnesium carbonate, and 5% protein. The production method is: Wash the eggshell with clean water, put it in boiling water for half an hour, then remove it and dry it or dry it, then pulverize it to the end, and it becomes a high-quality mineral feed for livestock and poultry. According to the proportion of 1% to 2% of the pig diet, 0.5% to 1% of the cattle and sheep diet, and 3% to 4% of the diet of the laying hens were mixed into the feed.
2. Silkworm sand: Each kilogram silkworm sand (silkworm manure) contains 85 grams of digestible protein, and the heat energy reaches 15.15 kilojoules. Therefore, it is faster and cheaper to feed the pigs with silkworm sand than to use a single feed. The method is also simple, as long as the silkworm sand is dried and then crushed and then put in clean water for 2 to 3 hours. After softening, 10% of the pig diet, 15% of the shelf pig, and 20% of the big pig are mixed into the feed. Feed it.
3. Heterogeneous bone: Heterologous bone is rich in calcium and phosphorus and is a high-quality mineral feed for livestock and poultry. Put a variety of animal bones into the pot, add grass and gray water (10 kg of water and 2.5 kg of ashes) and cook. While cooking, scoop up the oil and bone glue and continue to add grass and gray water until there is no water on the water. When the oil is removed, the bones are removed and dried. The large pieces are chopped into small pieces and then smashed and sieved to form the bone meal. When used according to the required amount of livestock and poultry added to the feed and mix feeding.
4. Corncob: The corncob contains 2.2% crude protein, 0.4% crude fat, and 29.7% crude fiber. It also contains minerals, vitamins, and trace elements. Just dry it and crush it into a powder. Prior to feeding, feed 5% to 8% of the pig's diet, saturate it with water, soften it, and feed it in the feed.
5. Peanut shell: It contains fat, starch, sugar and minerals, vitamins and so on. Crush it and mix it in wheat bran and feed at a rate of 10% for feeding chickens.
