6 reasons piglets grow slowly, pig farmers should learn about them early

1. Improper weaning: Farmers @#@227@#@ often use the one-time weaning method, and the piglets are sold immediately after weaning, causing the piglets' original living conditions - centered on the mother and living together with littermates in a stable and comfortable environment - to suddenly change, making it difficult for them to adapt for a time and affecting weight gain. The number of sucklings given to piglets should be gradually reduced 5 to 6 days before weaning until weaning is complete.

2. Delayed supplementary feeding: If piglets are not given supplementary feed in time during the suckling stage, they cannot eat well after weaning, resulting in slow growth and stunted development. Generally, supplementary feeding should start when piglets are 10 days old, beginning mainly with feed that is fragrant, sweet, crisp and easy to digest, and then gradually switching to normal feed.

3. Unreasonable feed and feeding methods: After weaning, piglets not only cannot get sow's milk, but the feed quality is also poorer than during the suckling period, and the daily feeding frequency drops sharply from 6 to 8 times before weaning to 3 times a day. These drastic changes hinder the piglets' normal development. Therefore, when buying pigs, you should ask the seller in detail about the feeding and management conditions of the pigs, so that feed quality transitions gradually and feeding frequency transitions gradually from many to few.

4. Too great a change in environmental conditions: Before weaning, piglets are centered on the mother and live together with littermates. After weaning, they are generally kept one pig per pen, and the piglets cannot adapt to this lonely life in a short time. Especially in winter, due to cold weather, they cannot eat or sleep well and are prone to illness or even death. Therefore, when buying pigs, try to understand their original feeding conditions as much as possible, create a comfortable living environment for the piglets, and make changes in feeding conditions gradually.

5. Extensive management: At present, farmers generally raise pigs one per pen, and some pigs eat, sleep and defecate in the same place. In addition, cleaning and bedding the pens are not done frequently, resulting in a filthy environment and extremely poor sanitary conditions. Especially in winter, this can easily cause a series of diseases such as colds and diarrhea in pigs, which is extremely unfavorable to their growth and development. In actual pig production, pigs can be grouped according to how fast they eat and their temperament, with 3 to 6 pigs per pen, so that the pigs compete for feed and grow quickly. In addition, training should be done well so that they eat at a fixed place, defecate at a fixed place and sleep at a fixed place, maintaining environmental sanitation.

6. Incorrect timing of epidemic prevention and castration: Farmers mostly buy pigs at the market and carry out epidemic prevention and castration at the same time as purchase. In this way, the three unfavorable factors of weaning, epidemic prevention and castration are all imposed on the piglets at once, so that the piglets cannot recover their body weight for a long time, seriously affecting the pigs' normal growth and development, causing slow growth and resulting in runt pigs. Generally, male piglets not retained for breeding can be castrated at 20 days of age, and female piglets at 30 to 40 days of age. To prevent certain infectious diseases, swine fever vaccine can be injected before pigs are 30 days old, and erysipelas vaccine can be administered at 90 days of age.
