The reason why fattening pigs grow slowly

Pig breeding technology has been very mature in our country. In breeding, pigs are generally fat-based. In the process of fattening pigs is called fattening pigs, but people will find that the growth rate of fattening pigs is very slow. So what is the reason for this? How can we improve the situation? Then let's introduce it to you by the editor. Let's have a look.

1. Variety reasons

At present, there are many pig breeds in China, and each breed has its own different growth characteristics. It is not enough that the growth ability of some pigs is relatively weak, such as native pigs, compared with three-yuan pigs, the fattening ability of native pigs is far inferior. It is entirely because of the breed that fattening pigs grow slowly, there is no effective solution to this reason, although it can be slightly improved, but the effect is not very good. Be sure to select a good variety before breeding, if it is already in breeding, then you can only introduce new species again.

2. Improper feed

The storage time of feed should be controlled within a reasonable range. Because if the time is too long, it will affect the palatability and quality of the feed, and the feed is easy to deteriorate, the loss of nutrition is also more serious, resulting in the growth of pigs is hindered. And some farmers blindly fattening, do not pay attention to the proportion of nutrients in feed, resulting in a serious lack of protein, energy and other nutrients. And the use of excessive fiber feed leads to the decrease of feed digestibility, which affects the growth of fattening pigs, so we must control the nutrition ratio of feed to ensure that the feed is clean and promote the growth of finishing pigs.

3. Overuse of antibiotics

In order to prevent diseases in pigs, many farmers will add a lot of antibiotics to their feed. Although antibiotics can improve disease resistance in pigs, it can lead to bacterial resistance over a long period of time. And the diseases caused by these bacteria are very difficult to cure. It will also lead to reinfection in pigs and reduce the immunity of pigs. It leads to a series of bad phenomena such as fighting and tail biting in pigs, which seriously affects the growth of fattening pigs. Therefore, we must pay attention to control the amount of antibiotics, not to use blindly, to ensure that the purpose of disease resistance can be achieved.

4. Disease harm

Disease is also one of the main reasons for the slow growth of fattening pigs, such as African classical swine fever, gastrointestinal diseases and various respiratory diseases. Most diseases harm the intestines and stomach of pigs, leading to a series of gastrointestinal problems. Not only affect the intake of pigs, but also lead to diarrhea, indigestion and other phenomena, reduce the absorption capacity of nutrients, and can not be absorbed in serious cases. As a result, fattening pigs are not only unable to gain weight, but also lose weight, resulting in death. And parasites are also the main cause of weight loss and slow growth in pigs. Therefore, we must do a good job in immunization, strengthen deworming management, and prevent diseases and parasites from affecting the normal growth of fattening pigs.

The above is a brief introduction of the reasons for the slow growth of fattening pigs, and the specific improvement methods still need to be determined according to the specific reasons. And the reasons that affect pig fattening are environment, drinking water and other factors, so we must pay more attention to it. That's all for today's introduction.
