Evaluation of methanol‐grown bacteria as a source of protein and energy for young chicks

Abstract
The inclusion of 100 or 200 g/kg spray-dried methanol-grown bacteria in unpelleted semi-purified diets reduced growth rate and efficiency of food conversion of young chicks over a 14 day period. Classical metabolizable energy values for the spray-dried product, at relatively low inclusion rates, ranged from 9.55-10.92 MJ/kg dry-matter (DM) and nitrogen-corrected values ranged from 8.95-10.16 MJ/kg DM. Inclusion of 96 g/kg flash-dried methanol-grown bacteria in unpelleted semi-purified diets marginally increased growth rates, efficiency of food conversion and nitrogen utilization of chicks, but higher inclusions up to 290 g/kg caused adverse effects.
