(Agricultural Wealth Network) What causes piglets to grow slowly?
--------------------------------------
1. Improper weaning
Farmers mostly use the one-time weaning method for pigs, and the piglets are sold immediately after weaning, which suddenly changes the piglets' original living conditions centered on the mother and cohabiting with littermates, stable and comfortable, making it difficult for them to adapt for a time and affecting weight gain. 5 to 6 days before weaning, the number of suckling times for the piglets should be gradually reduced until weaning is complete.
--------------------------------------
2. Untimely supplementary feeding
If piglets are not given supplementary feed in time during the suckling stage, they cannot eat well after weaning, causing slow growth and stunted development. Generally, supplementary feeding should start when piglets are 10 days old, beginning 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 worse 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 normal development of piglets. Therefore, when buying pigs, you should ask the seller in detail about the feeding and management conditions of the pigs, so as to gradually transition the feed quality and gradually reduce the feeding frequency from many to few.
--------------------------------------
4. Too great a change in environmental conditions
Before weaning, piglets are centered on the mother and cohabit 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, create a comfortable living environment for the piglets, and carry out 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, it 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 food and grow quickly. In addition, training should be done well so that they eat at a fixed point, defecate at a fixed point and sleep at a fixed point, 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 piglet at once, making it impossible for the piglet to recover its body weight for a long time, seriously affecting the pig's normal growth and development, causing slow growth and forming a runt pig. Generally, male piglets not kept 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.
