When feeding sweet potatoes, it is necessary to make a reasonable match with the fine ingredients so as to complement each other. Promote healthy growth of pigs. The preparation method is to remove the fresh potatoes in the recipe, remove the mud and lumps, and pulverize them into the potato pulp. Then stir in the rice bran and a bag of compound microbial starter, mix well and adjust the water content of the mixture to 65% to 70. %, re-inserted airtight, watertight, sterile plastic bag or concrete pool. First lay a layer of 25 to 30 cm thick bran on the bottom layer, then pour in the mixture, compact it with edges, and leave no gaps. Finally, cover the top with a layer of bran, which should not be filled too full. Fermentation overflows juice, tightly sealed with plastic film, often checked, and seams are immediately covered.
Feeding method
After three days of silage fermentation, when the fermentation material has sweetness, acidity, and flavor, the daily fermented yam material can be converted and converted according to the water content of the fermented material at that time and the proportion of yam in the feed for every 50 kg of dry matter. The corn flour, bean cake, silkworm cocoon and special compound additives in the formula are blended in proportion, and the mixture is fed, free to feed, drink enough water, and the fermented feed is preserved at any time after being taken out.
First mix green feed with compound feed, mix and feed, then feed cooked sweet potatoes. Or feed the green feed first and then feed the cooked compound feed. Do less to add ground, regular ration, for enough drinking water, in order to help improve their digestive capacity.
The amount of feed should be determined based on the pig's weight, age, sex, etc. The amount of feed is too large, other feeds eat less, and no comprehensive nutrition is available. In general, piglets, sows, breeders and boars should be fed less. The daily feed should be controlled at about 20% of the diet. Pigs weighing 35 kg or less should be fed 1.5 to 2 sweet potatoes and green feed each day. 5 kg, 0.8 kg of compound feed; 35-60 kg of pigs, 3.5-4.5 kg of sweet potato and green feed per day, 0.9-1.0 kg of compound feed, and 60 kg of pigs per day Each feed sweet potato and green feed each 5 ~ 7.5 kg, with feed 1 ~ 1.25 kg.
Poisoning treatment
Pig disease potato poisoning often occurs 3 to 4 days after eating, showing elevated body temperature, loss of appetite, constipation, fecal dry black ball, and often accompanied by mucus and blood. Once porcine poisoning is detected, laxatives may be given internally and gastric lavage may be performed with 0.1% to 0.2% potassium permanganate or 1% cupric sulfate solution; 20% U.S. can be used when metabolic dysfunction presents acidosis. Lotropine solution 50 ~ 100 ml intravenous injection; people with respiratory difficulties subcutaneous injection of aminophylline or atropine, nikethamide, etc.; weak heart can inject cardiac agents to enhance heart function, is conducive to rehabilitation.
Precautions
Do not use raw sweet potatoes to feed the pig, otherwise it will cause diarrhea, indigestion and loss of appetite. Piglets, sows and boars should be fed less sweet potatoes. If a large number of sweet potatoes are the staple food for a long period of time, neglecting the combination of protein feed and green feed can easily lead to swollen piglets.
