Respiratory disease prevention and control program for growing and fattening pigs, you're welcome to take it away!

For pig farms, more than 60% of the disease losses come from respiratory diseases; as the saying goes, "do not treat ringworm on the outside and asthma on the inside", indicating that respiratory diseases have always been a difficulty in the prevention and control of epidemic diseases in pig farms. A variety of respiratory pathogens can cause lung macrophage damage, resulting in poor resistance to the disease in pigs; respiratory diseases cause immunosuppression and cannot produce high and neat antibodies after vaccination The growth rate of pigs infected with respiratory disease was slow, the time of leaving the fence was delayed, and the feed conversion rate was low.

Due to the high feeding density, complex pathogens and antibody attenuation of growing and fattening pigs, respiratory diseases will become more prominent with the advent of autumn and winter, so it is particularly important to prevent and control respiratory diseases.

The proposed prevention and control programs are as follows:

Find out the law of the disease in this field.

Generally speaking, there are three important stages of respiratory diseases in growing and fattening pigs:

The above respiratory diseases will be different in different pig farms. Pig farms should do preventive treatment in advance according to the law of this farm to avoid high treatment cost and low cure rate in case of sudden problems.
