An extensive experiment on standard yard heat preserving pigsty has been carried out for four years The results showed that the surrounding constructure and bed of room met the requirements of heat preservation design The temperature and relatie humidity in the pens kept at 9 84 ℃ and 0 9% respectively The pens were warm and dry during winter However,there was a 3 ℃ difference in temperature between in and out of the house Performance of pigs was improved,the overall average daily gain for one year was about 643 65 g Ventilation system was valid,the air contents of NH 3,H 2S and CO 2 in the house was 6 9 cm 3/m 3,5 34 cm 3/m 3 and 0 003 1 m 3/m 3 respectively The pig house was arranged for convenient rational management
