Abstract
A total of 450 day - old Oornyati ducklings were randomly divided In to three equal groups according to litter type treatment. Each group was reared on different kind of litter by wheat straw (Tit). line sawdust (Tr2) and wood shaving (Tr3). A study was carried out to determine the effect ol different litter on ammonia emission in duckling houses. The results obtained were as fellows: The ducklings reared on fine sawdust were significantly heavier in body weight than other treatments at 4. 8, 20 weeks of age and not sig‌nificance at 16 weeks. The Interaction between treatment and sex was not significant at all ages studied except at 12 weeks of age. For growth rate (GA) the results showed that ducklings grew fast‌er at early ages (0-12 weeds of age) than those in the late period. Tho titter type effect on (GR) was noticed since ducklings reared on fine sawdust were significantly higher than the other titters at all ages except at 12 and 16 weeks. Shank length and body depth increased with the advance in age. Shank length was influenced significantly by litter type and sex at all ages Carcass traits for ducklings reared on wheat straw scored high value in percentages of feather. carcass. heart. fore4 hind- quarter as compared with those roared on the other two types of litters. It was found that wheat straw kept the highest quantity of am-monia followed by wood shaving, while, fine sawdust reserved the lowest quantity of ammonia.
