Abstract

This paper aims at evaluating the efficacy of LFS (Liquid Feeding System) which feeds shochu distillery byproduct as liquid feed in a pig farm from a perspective of CO2 emission. Specifically, by obtaining the survey data in the business (brewing manufacturer, pig farm) which adopted LFS in Kagoshima Prefecture, the comparison with the other processes such as the formation of dried feed mainly used in the feed-producing technique, was performed. As a result, it was found that the CO2 emission per pig was reduced 3% as compared with the case where the usual formula feed was used, and the CO2 emission per pig was reduced 18% as compared with the case where the same amount of shochu distillery by-product was made into dried feed. Furthermore, while confirmed that it has an economic advantage over the other processes of feed formation, it was objectively shown that this is a mechanism which is beneficial to both brewing manufacturers and pig farms.
