Abstract
A total of 168 seven days-old Arbor Acres chicks were reared in late-autumn on 4 types of litters; sawdust, rice husk, sugarcane bagasse or wheat straw up to 49 days of age to compare the growth performance, evaluate the manureal value and Coccidial oocyst population in used litter. Sadust, rice husk, sugarcane bagasse and wheat straw did not differ statistically for live weight, feed consumption, feed conversion ratio and survivability (p>0.05). However, live weight and survivability tended to increase on sawdust. The highest moisture content of used litter was found in sugarcane bagasse followed by sawdust, rice husk and wheat straw (p<0.05). Rice husk contained the highest amount of of nitrogen, phosphurus and potassium followed by sawdust, sugarcane bagasse and wheat straw (p<0.01). Oocyst content of all treatment groups increased suddenly up to 5 weeks of age and thereafter suddenly declined up to 7 weeks of age. Litter materials did not differ at 35 and 42 days of age for oocyst content, but significantly differed at 49 days of age (p<0.01). So, the above findings reveal that sawdust may be suitable litter followed by rice husk, sugarcane bagasse and wheat straw in late-autumn in Bangladesh in respect of broiler growth performance.

Highlights
Broilers are generally reared on littered floor
Body weight tended to increase on sawdust treatment group but it was very closed to rice husk and sugarcane bagasse and wheat straw treatment groups
By sugarcane bagasse, sawdust and wheat straw, which was contradicted with Anisuzzaman and Chowdhury (1996), Growth performance who found the lowest feed conversion efficiency on rice Birds reared on different litter materials showed non- husk than those on sawdust, chopped wheat straw and sand
Summary
Broilers are generally reared on littered floor. The purpose of using litter on floor is to absorb moisture from birds, dropping to keep floor reasonably dry and to ensure comfortable condition for birds. Rice husk contained the highest amount of of nitrogen, phosphurus and potassium followed by sawdust, sugarcane bagasse and wheat straw (p
