| Outline of Final Research Achievements |
Recycling of beet top for the dairy fermented feed was examined using mixed microbial preparation (BIO-PKC). To secure the safety and conservation of the BIO-PKC fermented beet top oxalate and nitrate contents, coliform bacteria, mycotoxin and residual pesticides were analyzed and secured. Feed value of BIO-PKC fermented beet top as a dairy feed ingredient was demonstrated by the digestion and nitrogen balance trials using sheep and feeding trial as the total mixed ration using the milking cows in the conventional dairy farm. The possible suppression of somatic cell counts suggested a prophylactic effect of BIO-PKC on mastitis of dairy cow. To activate cellulose and hemicellulose hydrolyzing ability of BIO-PKC by the control of oxidation–reduction potential the bioreactor equipped with redox potential controller was developed. In the fermentation with voltage applied BIO-PKC the hydrolases of cellulose and hemicellulose of beet top was accelerated and eventually saccharified.
