AB  - Anaerobic co-digestion of a mixture of industrial animal by-products (ABP) from 
      meat-processing in conjunction with dairy cattle slurry (mixed in a ratio of 1:3; 
      w.w.) was evaluated at 35  degrees C focusing on methane production and stabilization. 
      Three pre-treatments were applied (1) digestion with no pre-treatment (control), 
      (2) ultrasound, and (3) thermal hygienization (70  degrees C, 60 min). Methane production 
      potentials (MPP) of the untreated, ultrasound pre-treated and hygienized feed 
      mixtures were 300, 340, and 360 m(3) CH(4)/t volatile solids (VS) added, as 
      determined in the batch experiments. However, the specific methane productions 
      (SMP) achieved in reactor experiments (hydraulic retention time HRT 21 d, organic 
      loading rate OLR 3.0+/-0.1 kg VS/m(3) d) were 11+/-2% (untreated and ultrasound 
      pre-treated) and 22+/-3% (hygienized) lower than the potentials. Ultrasound with 
      the energy input of 1000 kJ/kg total solids (TS) and hygienization of the 
      ready-made feed were the most suitable pre-treatment modes studied.
