Six reasons for slow growth of piglets

Unreasonable weaning farmers adopt one more weaning method for raising pigs, and immediately appear on the market after weaning, so that the original maternal-centered, cohabiting, stable and comfortable living conditions of the pigs have suddenly changed, and the weight gain of the pigs has been affected because it is difficult to adapt for the time being. The number of breastfeeding of pigs should be gradually reduced 5-6 days before weaning until completely weaned. This method is very beneficial to the growth of pigs. The pigs were not fed in time during the lactation stage, and they could not eat well after weaning, and there was no milk supplement, which caused slow growth and stopped development. Generally speaking, feeding should be started at the age of 7 days, so that when the milk yield of sows decreases, they can be fed formally to make up for the lack of milk production of sows. At first, it was mainly fragrant, sweet, crisp and digestible, and then gradually changed to normal feed. After unreasonable feed and feeding methods, not only the pigs could not eat breast milk, but also the feed quality was very poor, there was more water and less feed in the feed, and the daily feeding times decreased sharply from 6 to 8 times before weaning. The drastic changes of these conditions hindered the normal development of son pigs. Therefore, when buying pigs, we should ask the seller in detail about the feeding and management of pigs, so as to ensure the gradual transition of feed quality and quantity, the gradual transition of fine green roughage, and the gradual transition of feeding times from more to less. | the environmental conditions change too much. Before the pig is weaned, it takes the mother as the center and the siblings live together. After weaning, it is usually a circle of pigs, and pigs can not adapt to this lonely life in a short time, especially in the cold weather in winter, which can not eat well and sleep well, and is prone to a variety of diseases and even death. Therefore, when buying pigs, we should try to know more about their original feeding situation, create a comfortable living environment for pigs, and the change of feeding conditions should be carried out gradually. Extensive management now farmers generally raise pigs in a circle, and some pigs eat, sleep and defecate in the same place, coupled with the lack of diligent cleaning and washers, resulting in environmental pollution and poor sanitary conditions, especially in winter. it is easy to cause a series of diseases such as pig colds and dysentery, which seriously affect the health of pigs and are extremely disadvantageous to growth and development. In the actual pig production, 3-6 pigs can be used as a circle according to the speed of eating and temperament, so that pigs compete for food, grow fast, and do a good job of training to make them eat, defecate and sleep at a fixed point, so as to keep the environment hygienic. In the time of epidemic prevention and castration, farmers do not buy more pigs to the market, and carry out epidemic prevention and castration at the same time. In this way, the three unfavorable factors of weaning, epidemic prevention and castration are added to the pigs, so that the weight of the pigs can not recover for a long time, seriously affecting the normal growth and development of the pigs, the pigs grow slowly and form stiff pigs, resulting in undue losses. Generally speaking, young boars without breeding can be castrated at 20 days old and sows at 30-40 days old. In order to prevent some infectious diseases, classical swine fever vaccine can be injected before 30 days old, and erysipelas vaccine can be carried out at 3 months old.
