When asked about epidemic prevention, do not buy piglets from the affected area and understand what kind of vaccine was injected.

Do a good job of immunization, deworming, gastric lavage, and stomach-building before fattening. The piglets should be injected once to the site and should be immunized once (usually pigs and pig amphibians are used together). On the 2nd day, the insects were dewormed and fed with levodozole or albendazole tablets. The pigs were fed with 25 mg per kilogram of pig body weight and mixed into the feed to drive off the parasites. The surface of the pig was sprayed with 3% to 5% of trichlorfon solution to drive off the ectoparasites. Day 4 gastric lavage for 2 consecutive days. On the 6th day, the stomach was treated with rhubarb soda (2 tablets per 10 kg body weight) and fed into the feed three times.

Take reasonable nutrition and scientific feeding management measures. During the rearing period of the finishing pigs, it is better to feed in two stages according to the body weight (25-60 kg in the pre-fattening period and 60-100 kg in the later period). According to the nutritional needs of the pig, select the local breeding resources and use the concentrated premix to prepare the pigs. Full price diet. Establish a regular and quantitative feeding system. In order to promote digestion and improve feed utilization and growth rate, daily diets for finisher pigs can be fed in three separate feedings. The daily feed supply per pig can be quantified at 3.5% to 4.5% of the pig's body weight. In addition, the appetite of pigs is generally the highest in the evening, followed by the morning, and the weakest at noon. Therefore, the amount of feed each time during the day can be roughly distributed at 35% in the morning, 25% at noon, and 40% in the evening.
