What are the reasons why fattening pigs grow slowly?
Pig farming technology has long been very mature in our country. When raising pigs, the main goal is generally to put on fat. In the process of making pigs put on fat, they are called fattening pigs, but everyone will find during fattening that some fattening pigs grow very slowly. So what is the reason for this? How can this situation be improved? Now let me introduce it to you below, let's take a look!
1. Breed reasons
There are now very many pig breeds in our country, and each breed has its own different growth characteristics. However, the growth ability of some pigs is relatively weak, such as local crossbred pigs. Compared with three-way crossbred pigs, the fattening ability of local crossbred pigs is far inferior. This is entirely due to breed reasons causing fattening pigs to grow slowly. There is no effective solution for this reason. Although it can be slightly improved, the effect is not very good. Before farming, you must choose the breed well. If you are already farming, then you can only introduce new breeds 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 prone to spoilage, with relatively serious nutrient loss, causing the growth of pigs to be hindered. In addition, some farmers blindly fatten them, not paying attention to the nutritional ratio in the feed, resulting in a serious lack of nutrients such as protein and energy. And using excessive amounts of fibrous feed leads to a decrease in feed digestibility, thereby affecting the growth of fattening pigs. Therefore, we must control the nutritional ratio of the feed well, ensure the feed is clean, and promote the growth of fattening pigs.
3. Excessive use of antibiotics
Many farmers add large amounts of antibiotics to feed during farming in order to prevent and treat diseases in pigs. Although antibiotics can improve pigs' disease resistance, over a long period they will cause pathogens to develop resistance. Moreover, diseases caused by these pathogens are very difficult to cure completely. They will also cause pigs to be infected again, reducing the pigs' immunity. This causes a series of adverse phenomena such as pigs fighting and tail biting, seriously affecting the growth of fattening pigs. Therefore, we must pay attention to controlling the amount of antibiotics, not use them blindly, and ensure that the disease resistance goal is achieved.
4. Disease hazards
Disease is also one of the main reasons causing fattening pigs to grow slowly, such as African swine fever, gastrointestinal diseases and various respiratory diseases. Most diseases will harm the pig's gastrointestinal tract, causing a series of gastrointestinal problems. They not only affect the pig's eating, but also cause diarrhea, indigestion and other phenomena in pigs, reducing nutrient absorption capacity, and in severe cases even making absorption impossible. This causes fattening pigs not only to fail to gain fat, but also to lose weight, leading to death. In addition, parasites are also a main reason causing pigs to become thin and grow slowly. 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 to the reasons why fattening pigs grow slowly. The specific improvement methods still need to be determined by everyone according to the specific reasons. In addition, the reasons affecting pig fattening also include various factors such as environment and drinking water, so everyone must pay more attention. That is all for today's introduction.
