Pig respiratory disease syndrome is characterized by decreased growth rate, reduced feed utilization, loss of appetite, cough, and difficulty in breathing. Although the overall mortality rate is not high, it can seriously affect the economic benefits of the farm. Therefore, I hope to be able to control the disease in time, prevent diseases, and improve the interests of pig farms.
At present, respiratory diseases syndrome has some new features. First, the pathogens that appear as mixed infections have changed from previous years. The pathogens are Mycoplasma pneumoniae, Reproductive and Respiratory Syndrome Virus (PRRSV), and Type 2 circovirus ( PCV-2) and other infections are dominant, and then combined with other bacteria secondary or mixed infection. The second is the change of onset time, which is manifested as the incidence of pigs at various stages after weaning, that is, respiratory disease syndrome can occur from 2 weeks after weaning to the fattening period.
Prevent diseases in time:
Strengthen feeding management Introduce breeding pigs without respiratory symptoms, and do a good job of isolation and assimilation. Sows delivered in the same unit have equal or similar parity. Weaned piglets were kept in the same column during the same week. The method of all-in and all-out is less common than that of running water.
Reduce harmful gases such as ammonia, control of ventilation and temperature, control of stocking density, set up isolation bars for sick pigs, timely isolate and treat sick pigs in nursery houses or growth houses, and strengthen disinfection and other measures.
