Abstract:

n this study we chose 2 microorganism fermentation bed pigsty. The improvement of pigsty temperature, humidity, THI and the effect of body temperature, feed intake, weight daily gain, feed conversion ratio, economic benefits in the fermentation bed pigsty installed with the micro-climate control system are for comparative analysis. The results show that using the south area micro-climate control system in the fermentation bed pigsty in summer can significantly improve the micro-climate in pigsty, ensure the health of swine, increase the daily gain and feed efficiency.
