Abstract


Three hundred and twenty-four Hysex-brown layers, ll month of age, were used to
study the ammonia production and manure house fly larvae population. Manure was removed every 10, 20 and 30 days, from cage densities of 1 and 2 layers per cage. The result showed that ammonia production and house fly larvae population, faecal temperature and water content of manure significantly (P<.05) increased by treatments, but the effects were not significant on feed consumption, hen day production, egg weight and total manure production respectively.
