Abstract


This experiment was conducted to study the effect of incorporating zeolite in the diet and spreading on to manure on the population growth of house flies, manure ammonia production and layer performances. 486 Hysex-brown layers, 7 month of age, were divided into 3 treatments and fed with 0, 6 and 12% levels of zeolite in the diets, and spreading of zeolite on to manure at 0, 6 and 12% of total daily feed intake every 4 days. The result of this experiment showed increasing levels of zeolite in the diets and levels of zeolite spreading on to manure significantly (P<.05) decreased the larvae population of the house flies, ammonia production and water content of manure respectively. lncotporation of high level of zeolite in the layer diets affected significantly (P<.05) the feed conversion ratio, hen day production and shell thickness
but not significantly on feed consumption, egg weight, shell weight, length and weight of tibia, respectively.
