A method and apparatus for pre-treatment of a fresh manure slurry stream. The method alters gas production during subsequent treatment or holding. The method passes the stream through a pre-treatment zone in which the slurry is subjected to alternating electrical current depositing energy from about 1.1x10-2 J/cm3 to 4.1x10-1 J/cm3. The apparatus includes first and second spaced apart electrodes of inert material which define a pre-treatment zone between the electrodes and preferably induce turbulence in the stream within the pre-treatment zone.
