Why do piglets grow slowly?

Some farmers reflect that the piglets raised at home grow very slowly. What on earth is the reason? According to the analysis, there are the following reasons.

1. Unreasonable weaning farmers adopt one more weaning method and go on the market immediately after weaning, resulting in a sudden change in the piglets' original maternal-centered, stable and comfortable living conditions among their siblings, which is difficult to adapt to and affect weight gain. The times of lactation of piglets should be gradually reduced within 5-6 days before weaning until they are completely weaned.

2. the piglets were not fed in time during the lactation stage, and the piglets could not eat well after weaning, which led to slow growth and stop development. Generally speaking, piglets should be fed 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.

3. after unreasonable feed and feeding methods, not only the piglets 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 to 3 times a day. The drastic changes of these conditions hindered the normal development of piglets. 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.

4. The environmental conditions changed too much. Before weaning, the piglets took the mother as the center, and the siblings lived together. After weaning, it is usually a circle of pigs, piglets can not adapt to this lonely life in a short period of time, especially in the cold weather in winter, can not eat well and sleep well, it is easy to produce a variety of diseases and even death. Therefore, when buying pigs, we should try to know more about their original feeding situation, to create a comfortable living environment for piglets, and the change of feeding conditions should be carried out gradually.

5. 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 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 colds and dysentery in pigs, which seriously affect the health of pigs and are extremely disadvantageous to their growth and development. In the actual pig production, according to the speed of eating and temperament, 6 pigs can be used as a circle, so that pigs compete for food, grow fast, and do a good job of training, so that they can eat, defecate and sleep at a fixed point, so as to maintain environmental hygiene.

6. During 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 piglets, so that the weight of the piglets 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, causing undue losses. Generally speaking, young boars can be castrated at 20 days old and sows at 30-40 days old. Classical swine fever vaccine can be injected before 30 days old to prevent some infectious diseases, and erysipelas vaccine can be carried out at 3 months old.
