In the rural pig production, the breeders often fall into the wrong zone due to lack of scientific knowledge of feeding management and epidemic prevention, which is a problem worth noting. 1. Inbreeding Some pig farmers use their litters for breeding and parental breeding. This kind of inbreeding violates the principle of pig breeding, making pigs more and more degenerate, affecting the quality and economic efficiency of pigs. 2. Early weaning of weaned pigs Weaning prematurely or early weaning can cause piglets to grow stagnant and form stiff pigs. Late weaning can result in longer reproductive cycles and fewer farrowing litters. General piglet weaning time is suitable for 45-50 days old. 3. Improper feeding time is not fixed, the amount of feeding is not equal or too large. Excessive feed on shelf pigs causes premature fat deposition and affects bone growth. Therefore, it is appropriate to reduce the amount of concentrate and increase the feed with higher protein and vitamin content. 4. Suddenly changing the feed will cause a stress response to the pig, causing the pig's appetite to subside over time and affecting growth. 5. Do not pay attention to the improvement of environmental sanitation Some pig farmers have poor pigs' health and feeding conditions. They do not clean up the sewage for a long time. The pig houses are not protected from the cold in summer and summers are not. This will not only cause the pig's physical decline, but also easily spread the disease. 6. Mixed Breeding Feeding pigs regardless of size, use, and breed is not only unfavorable to the use of feed and pens, but also results in pigs being bullied, biting each other and causing death and injury. 7. Not paying attention to epidemic prevention and eradication There are a large number of breeders with pigs who are not sick and who do not take injections. Once a disease occurs, it is not hesitate to spend a lot of money on veterinarians or drug purchasers, resulting in increased expenses, which is not worth the candle. Even the phenomenon of spending money to cure bad illnesses.
