I. Weaning is unreasonable Farmers raise their pigs to take a weaning method and go on the market immediately after weaning. This makes the piglets have a mother-centered, cohabiting, and stable and comfortable living conditions suddenly changed. It is difficult to adjust to increase weight. The number of piglet nurses should be gradually reduced until 5 to 6 days before weaning until complete weaning. This method is very beneficial to the growth of piglets. Second, feed is not timely The piglets did not fill the feed in time during the lactation phase. They did not eat well after weaning and there was no milk supplement, causing slow growth and development to stop. Feeding should normally begin at 7 days of age in piglets so that when the sow's lactation levels decline, it can be officially supplemented to make up for the lack of sow milk production. It started with fragrant, sweet, brittle and easily digestible feeds, and gradually changed to normal feed later. Third, feed and feeding methods are unreasonable After weaning, piglets are not only unable to feed on breast milk, but also the quality of feed is poor. Feeding materials are low in water, and the number of daily feeds is also reduced from 6 to 8 times before weaning and drastically reduced to 3 times a day. These conditions drastically change. The normal growth of piglets is hampered. Therefore, when buying pigs, it is necessary to inquire about the seller's feeding and management of the pigs in detail, so that the quality and quantity of feeds will gradually transition, the fine green forage will gradually transition, and the number of feeds will gradually transition from more to less. Fourth, the environmental conditions change too much Before weaning, piglets are mother-centered and co-habitants. After weaning, it is usually a pig lap. Piglets cannot adapt to this lonely life for a short period of time. In particular, the cold weather in winter can not sleep well and can easily cause multiple diseases and even death. Therefore, when purchasing pigs, it is necessary to understand as much as possible the original feeding conditions, create a comfortable living environment for the piglets, and gradually change the feeding conditions. Fifth, extensive management Now farmers raise pigs usually in a pig-circle. Some pigs eat, sleep and defecate in the same place. They also have poor cleaning and washers. They cause environmental pollution and poor sanitation. Especially in winter, pigs are easily caused. A series of diseases such as colds and diarrhea seriously affect the health of pigs and are extremely detrimental to growth and development. In actual pig production, 3 to 6 heads can be regarded as a circle according to the speed of eating and drinking, and the temperament is good. In this way, pigs compete for food, grow fast, and do a good job in tune up to make it a fixed point of eating, defecate excrement, sleep on a regular basis. To maintain environmental hygiene. Sixth, the epidemic prevention, the time of the castration is wrong Farmers buy more pigs than bazaars and conduct epidemic prevention and castration at the time of purchase. In this way, the three unfavorable factors of weaning, epidemic prevention and castration were all added to the piglets, so that the piglets could not recover in a long time, which seriously affected the normal growth and development of the pigs. The pigs grew slowly and formed stiff pigs. Caused undue losses. In general, small boars that do not remain in the seed can be castrated at 20 days of age and gilts can be aged from 30 to 40 days. In order to prevent certain infectious diseases, swine fever vaccine can be injected before the age of 30 days. Danish vaccines are available. At 3 months of age.
