Raising pigs without enclosure will spread the disease.

In order to raise pigs well, it is the key to strengthen the feeding management and enhance the disease resistance of pigs. The scientific method is to feed pigs in captivity to prevent pigs from running around and eating, so as to prevent infection. There is a saying among the people in our country that "if you don't raise pigs, you will spread the disease", which is reasonable. Some people think that pigs are kept separately, without disease or disaster, so that they can be fed easily and grow quickly. This statement is not scientific. Free-range pigs consume a lot of physical strength, not only do not gain weight, but also increase the chance of disease in pigs. For example, classical swine fever can be infected through mouth, nasal cavity, eye conjunctiva, reproductive tract mucosa and skin abrasions. Contact between infected pigs and healthy pigs will increase the chance of infection. For example, pigs with acne are infected as a result of loose pigs running and eating randomly and swallowing the feces of patients with tapeworm. For example, leptospirosis is a zoonosis. If the feces of diseased pigs pollute the food and drinking water that people eat, it is easy to transmit the disease to people. Free-range pigs not only spread diseases, but also lead to misbreeding and misbreeding, resulting in bad heredity. It can be seen that if we do not change this backward method of raising pigs as soon as possible, there will be endless troubles. In order to improve the efficiency of raising pigs, we must change the traditional habit of raising pigs in captivity, make sure that people have toilets and pigs have pens, strictly enforce the epidemic prevention system, and cut off the ways for pigs to be infected with epidemic diseases. In order to make effective use of pig manure, save feed, shorten fattening period and reduce disease, it is necessary to change bulk breeding to captive breeding in order to achieve low consumption and high efficiency. At present, the pig industry is changing from small-scale decentralized feeding to large-scale intensive feeding, which not only requires modern feeding and management methods, but also puts forward new requirements for pig disease prevention and control. Therefore, the establishment and improvement of pig farm epidemic control system can not be ignored. -A collection of good things.
