One, the whole group covered insecticide In the autumn, while doing a good job of cleaning and disinfecting the inside and outside of pigs and pig houses, the infection status of parasites is monitored through regular fecal examinations and necropsy, and disinfectants that effectively kill the coccidial oocysts are used. At present, avermectin is the main drug for killing parasites, mainly including powders, tablets, and injections. It is necessary to select a good time for the entire population to cover insects. Sows are dewormed 14 to 21 days before farrowing. Sows are used once in 14 days before breeding and boars are used once in spring and autumn. The most economical method for rearing pigs is to deworm once at 35 to 40 days of age, and then to deworm once every two months or so until slaughter. In addition, there are many parasite eggs in green feed, such as liver fluke, aphids, and other nematodes, which should be washed before feeding. Second, feed with feed Fine material, coarse material, and green material are properly matched. Concentrates and roughage should be crushed in order to facilitate the digestion and absorption of pigs. Whether it is using raw materials for wet feeding, or mixing the mixture with chopped green feed and letting pigs feed freely, the water content of the prepared feed should not be excessive. Piglets can supply 0.1% potassium permanganate solution to prevent white piglets. Pigs who feed dry materials should supply enough clean drinking water. In the autumn, the amount of drinking water is 4 times that of dry feed. Green material must be used with 40% of concentrate material, and 10% of glutinous rice cake can also be added to the feed. When feeding, generally feed the concentrate, and then feed the green material four times a day, preferably within half an hour each time. Many farmers still use pellet feed to feed pigs. Like the powder, they first add water to form porridge, and some even use boiling water to boil the material or cook it in a pot. This not only fails to reflect the superiority of pellet feed, but also makes The nutrition of granular feed was destroyed. Third, sweet potatoes with radish Sweet potatoes are high-energy feeds, and sweet potato should be mixed with corn, soybean cake, wheat bran, rice bran, fish meal, bone meal, additives and other feeds with high levels of protein, calcium, and phosphorus in order to ensure a balanced diet. In addition, the proportion of sweet potato in the whole feed should not exceed 50%, and do not use sweet potatoes alone to prevent malnutrition. Also do not feed. It is best to chop the sweet potatoes and radish that can promote digestion in a 2:1 ratio, boil and stew, and let them dry without adding hot dry yeast. Note that cooked sweet potatoes should not be stored in the pot too long to prevent spoilage. The proportion of sweet potato in the feed, piglets generally can not exceed 30%. Fourth, timely storage of feed Peanut pods, bean stalks, potato tubers, legume pods, etc. can be sun dried and crushed to feed the pigs. Grass, vegetables can be fermented or soaked into pickled cabbage. The specific method is: Wash grass, vegetables, melons, leaves and other short cuts, loading cylinders, compaction layer by layer, when the full loading of eight, covered with a straw, pressed on the stone, but without water. After a few days of feed sinking, fill the tank with water again. In order to isolate the air and ferment it for one more day, the pigs can be taken out. If the top of the cylinder is tightly sealed with a plastic film, the surrounding tightly sealed can be stored for a long period of time without deterioration, and it can also be dried or stored by drying. It should be noted that rapeseed cakes that have not been detoxified should not exceed 10% of the diet; legumes should be boiled and fed to facilitate the absorption of protein; the amount of feeding should be increased from small to large and the pigs gradually adapt.
