Several methods of raising pigs' grain

1. Bacteria meal feeds for pigs: After cultivation of edible mushrooms, crop straws and by-products, such as by-products, can be obtained after necessary treatment. In general, more than 60 kg of bacteria can be obtained per 100 kg of culture material. Feeding pigs with mash and spices is better than rice mash and can be used to approximate the feeding effect of corn. 1. Bacteria collection. After the edible fungus is harvested, the moldy material on the culture material is first removed and the soil is removed. After the mycelium has a large amount of odor and a strong taste, it is taken out and air-dried or dried, and the powder is drunk until it is used. 2. Feed before fermentation. Every 100 kg of sugar can be mixed with 40 kg of rice bran, and then add water. The amount of water is added by hand to squeeze the water between the fingers without drip, and it is put into a closed container (cylinder) for fermentation, and the food can be taken out when there is a fragrance of wine. 3. Control the dosage. Generally, the bacterial sugar before fermentation accounts for 10%-15% of the feed, 20%=35% of the diet after fermentation, the ratio should not be too large, and it is necessary to mix and match various feeds, and avoid single feeding. 4. Note. 1 Keep bacteria in good health to prevent mold deterioration. 2 Bacteria can be crushed and fed directly to the pig, but the feeding effect is not as good as after fermentation. 3 Each fermentation broth should not be too much, it is appropriate to use 5-7 days. Second, silkworm sand feed on behalf of pigs: silkworm sand contains Xin species of nutrients, is a good feed for pigs. The scientific use of silkworm sand to feed pigs not only reduces the cost of feeding by 15% to 20%, but also increases pig weight gain by 10% to 15%. Silkworm sand feeding pigs should grasp the following points: 1. Collection. The silkworm sand is collected and exposed to the sun, and impurities are removed to prevent moldy growth. After drying, the silkworms are crushed and stored for later use. 2. Processing. The silkworm sand should not be fed freshly. Generally, the finely chopped silkworm sand should be soaked in clean water for 2-3 hours before being fed, and then it can be mixed and fed to pigs after it is softened. 3. Dosage. The amount of silkworm excrement used in the feed is 5%-10% for pigs with 25-30kg of piglets in the growth stage of pigs, about 15% for shelf pigs for 30-60kg, and 20% for finishing pigs with 60kg or more. 4. Taboo. 1 Do not feed pigs with moldy spoilage. 2 Cannot be fed alone with cocoon, otherwise poisoning or even death will occur. 3 adhere to a variety of feed with. Third, the biogas slurry feed to pigs: Feeding pigs with biogas slurry, can promote growth, increase weight gain, save feed, shorten the fattening period. 1. Biogas slurry should be extracted from the pool of normal fermentation gas production. New pools or large refuelling ponds can only be taken after a normal production of gas for 1 month. They cannot be fed to pigs with diseased pools or toxic substances, otherwise they will be extremely hazardous. 2. The pH of the biogas slurry is preferably neutral, ie the pH should be maintained between 6-7.5. Before taking the liquid, use a wooden stick to write a few strokes at the inlet of the pool, and take the middle layer of clear liquid biogas. 3. After the biogas slurry is taken out, it should be left standing for a period of time, and then mixed with feed for independent accounting. The storage time of the biogas slurry should be controlled flexibly according to the temperature, generally half an hour is appropriate. For a long time, the biogas slurry is susceptible to bacterial spoilage. 4. The biogas slurry mixture should be fed to pigs in a wet mix. After the first feed, the water is poured and the water is available throughout the day. Biogas slurry must be dry and not wet, fully mix well, and then use hands to make a group to loosen the dispersion, and then feed the raw food. Before the feed, the pigs are dewormed. 5. Biogas slurry is suitable for feeding fattening pigs. It is better to start feeding 30 kg of pig weight, 90-110 kg can be slaughtered. Boars and empty sows should not feed biogas slurry to prevent excessive growth and affect estrus breeding. 6. When you begin to feed biogas slurry, you should let the pigs have a period of adaptation, and use less gradually. If live pigs co-exist diarrhea during the feeding process, biogas slurry should be stopped immediately for timely diagnosis and treatment. After being diagnosed without disease, after the symptoms of diarrhea have disappeared, biogas slurry can be fed again. However, if the dosage should be appropriately reduced, it can generally be reduced by 0.2 kilograms more than the original amount. 7. Biogas slurry can only be used as a feed additive and cannot be used as a substitute for concentrates. Only under conditions of adequate nutrient feed can fully function.
