摘要
[Objectives]The purpose was to solve the problem that high temperature and high humidity will seriously affect the health and weight gain of pigs.[Methods]The fan-water curtain cooling system was popularized in large-scale pig farms.[Results]The pigs using the water curtain cooling system gained 1.5 kg from weaning to the day of slaughter.The feed-to-gain ratio was 2.43∶1,a year-on-year decrease of 0.05.The average weight gain per pig was about 5-10 kg.[Conclusions]The application of fan-water curtain cooling system in pig production can accelerate the growth rate of pigs,reduce the occurrence of diseases and improve the utilization of feed,eventually improving the productivity of pigs.
