Abstract

[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.
