3.1. Physical parameters of fermented FWM
Physical parameters of the fermented FWM for swine
feed were analyzed subjectively by trained evaluators
(Table not presented). Both the 10- and 30-day observation
patterns for fungal growth and for alcoholic and acidic
odors were the same. The non-anaerobically (NAN) stored
FWM was putrefied and had significant fungal growth. The
anaerobically (AN) stored waste did not putrefy and fermentation
was evident by an acidic odor of the FWM.
Yeast fermentation was evident by an alcoholic odor of the
FWM, and this appeared to diminish as the lactic starter
inoculum addition to the FWM was increased.
