| At Khon Kaen in northeastern Thailand, energy metabolism in cattle was studied by a respiration trial system using a ventilated flow-through method with a face mask built with technical and financial support of Japan International Research Center for Agricultural Sciences (JIRCAS). Energy values of locally available feed resources have also been obtained from digestion and respiration trials. JIRCAS also had already completed a new ventilated head-hood apparatus for energy balance trials and started the data accumulation concerning the energy value of Pangola grass (Digitaria eriantha) with Brahman beef steers. As for the energy balance measurement technique, JIRCAS supports the establishment of feeding standard by measuring the energy requirement of... |

| The paper deals with the hygienic advantages of sanitation to treat dairy manure in full-scale biogas plants. Slurry samples were collected from two thermophilic biogas plants (55ºC) and two mesophilic biogas plants (38ºC) in Hokkaido, Japan. The detectable number of Coli-aerogenes group and Enterococcus in the slurries after anaerobic digestion could not be found in both thermophilic biogas plants. In both mesophilic biogas plants, however, the viable numbers of Coli-aerogenes group and Enterococcus were detected in the slurries even after anaerobic digestion. The mean decimation reduction time (T90) values of Coli-aerogenes group and Enterococcus in the slurries during mesophilic digestion were 13.3 d and 16.7 d, respectively. |
