Monitoring Of The Environmental Parameter Of Different Seasons And Different Types Pig House And The Effect On The Production Performance Of Piglets

This experiment is to provide a reference for for improving the environmental parameters and theoretical basic for creating a suitable environment for the growth in an enclosed barn, through monitoring the part of the environmental parameters and determining the production performance in summer and winter. The results of experiment show that:① The concentration of carbon dioxide, ammonia and hydrogen sulfide in lactation piglet house respectively was 2220mg/m3 and 4412mg/m3,2.11mg/m3 and 10.11mg/m3,0.72mg/m3 and 2.61mg/m3,the concentration in weanling piglets house respectively was 659.56mg/m3 and 4416.00mg/m3,1.55mg/m3 and 2.51mg/m3,0.42mg/m3 and 1.53mg/m3 in summer and winter. The concentration of harmful gases in winter were significantly higher than summer. The temperature of lactation piglet house was not significantly difference in summer and winter(respectively 25.91 ℃ and 24.47 ℃), the temperature of weaning piglets house was significantly different(respectively 27.87 ℃ and 21.07 ℃)② The concentration of carbon dioxide in lactation piglets house was significantly higher than that weaned piglets house in summer,but in winter there was no significant difference. The other harmful gas in lactation piglet house was significantly higher than weaned piglet houses. In the same season,to compared with weaning piglet house, the temperature of the lactation piglet houses increased 2~3℃.There was a highly significant difference in the humidity for lactation piglet and weaning piglets house in summer(respectively53.35% and 50.18%),but there was no significantly difference in winter.③The highest of harmful gas for lactation piglet and weaning piglets house appeared at 6:00 am in winter and summer, the highest temperature of weaning piglets house appeared in 11:00 noon in winter and summer. The highest temperature for lactation piglets houses appeared in 18:00 in summer, it appeared 11:00 in winter. The highest humidity for lactation piglet and weaning piglets house occurred at 18:00 in summer, it appeared at 6:00 in winter.④ The environment had significant influence on the production performance of the piglets. Better environment was advantageous to improve production performance of the piglets. It would significantly improve the nest weaning weight of lactation piglets and the daily feed intake and average daily gain of the weaned piglets.
