Abstract

Abstract:

In order to understand the impact of DTS deodorization equipment on the environmental indicators of pig barn and the health of pigs, a comparative experimental study was conducted. The experimental results showed that compared with the control group, the concentration of ammonia, hydrogen sulfide, and odor in pig barn using DTS deodorization equipment was reduced, with odor concentration decreasing by more than 95%. At the same time, there were no significant differences in the daily feed intake, daily weight gain, feed to meat ratio, litter size, live litter size, and average weight of newborn piglets between the experimental group and the control group. The results indicate that DTS deodorization equipment can be used to reduce the concentration of ammonia, hydrogen sulfide, and odor in pig barn, improve the pig breeding environment, and reduce the problem of breeding odor.

Key words: breeding environment, odor reduction equipment, foul odor, pig barn, pig health
