Tips for scientific feeding of deworming feed to promote fat gain of pigs in autumn

1. Whole-group coverage for deworming

In addition to doing a good job in cleaning and disinfection of pigs and pig houses in autumn, parasitic infection in pigs should be monitored through regular fecal examination and autopsy, and disinfectants that kill coccidia oocysts should be used to kill coccidial oocysts. At present, avermectin is the main drug to kill parasites in pigs, mainly powder, tablet, injection and so on. Sows are dewormed 14-21 days before parturition. Sows were used once 14 days before mating, and boars were used once in spring and autumn. Finishing pigs were dewormed once at the age of 35-40 days, and then once every 2 months until they were out of the pen. In addition, the green feed contains a variety of parasitic eggs such as Fasciola hepatica, Ascaris lumbricoides and other nematodes, which should be washed before feeding.

Raising pigs

Second, feed matching feeding

Fine material, coarse material and green material should be matched reasonably. Concentrate and roughage should be crushed to facilitate pig digestion. Whether it is wet feeding of raw meal, or mixing the mixture with chopped green fodder and allowing pigs to eat freely, the feed moisture should not be too much. Piglets can provide 0.1% potassium permanganate solution to prevent piglets from white dysentery. Pigs fed with dry feed should provide adequate clean drinking water, and the amount of water consumed in autumn is 4 times that of dry feed.

40% concentrate should be added to green feed, or 10% glutinous rice bran can be added to pig feed. When feeding, first feed concentrate, and then feed green feed, four times a day, each time within half an hour. When many pig farmers feed their pigs with pellet feed, like powder, they first add water to make porridge, and some even use water to flush or cook, which will destroy the nutrition of pellet feed.

3. Sweet potato with radish

Sweet potato is a kind of high-energy feed. Sweet potato should be scientifically mixed and mixed with feed with high protein, calcium and phosphorus content, such as corn, bean cake, wheat bran, rice bran, fish meal, bone meal and additives to ensure balanced feed nutrition. In addition, the proportion of sweet potato in the whole feed is less than 50%. Do not feed sweet potato alone to prevent malnutrition. Besides, don't feed me alive. It is best to cut up sweet potatoes and radish at 2:1, cook and stew, dry until not hot, then mix in the right amount of dry yeast, and then feed. Boiled sweet potatoes should not be kept in the pot for too long to prevent rancidity. The proportion of sweet potato in piglet feed is no more than 30%.

IV. Timely reserve of feed

Peanut seedlings, bean stalks, potato tubers and legume pods can be dried and crushed before feeding to pigs. Green grass and green vegetables can be fermented or pickled into sauerkraut and then fed to pigs. The specific method is: wash the grass, vegetables, melons, leaves and so on, fill the tank, compact layer by layer, when 80% full, cover with grass curtain, press the stone, but do not add water. After a few days, the feed sinks and the tank is filled with water. To isolate the air and ferment for another day, it can be taken out and fed to the pig. If the cylinder mouth is tightly sealed with plastic film, it can be tightly tied around and sealed, and it can be preserved for a long time without deterioration, and it can also be dried or dried. It should be noted that the undetoxified rapeseed cake should not exceed 10% of the pig diet; legume feed should be cooked and fed to facilitate the absorption of protein; the amount of feed should be from less to more, so that pigs can gradually adapt.
