The two commonly used litter materials in Bangladesh, wheat straw and sugarcane bagasse were examined for their suitability in broiler rearing. Chicks reared on wheat straw had a significantly higher (P less than 0.01) feed conversion ratio compared with others. Coccidial oocysts counts per gram of litter reached a peak at 5" week, and except a significantly higher (P less than 0.01) count in sawdust litter at 4th week the counts were not different between the groups. The birds were apparently healthy and did not have any physical abnormalities. Nitrogen content of different used litter did not vary significantly (P greater than 0.05) but the potassium and phosphorus contents in wheat straw were significantly higher (P less than 0.01) as compared with other litters. Considering the broiler performance sawdust was found to be the best litter, although wheat straw had a better manureal value but with poor broiler performance. Therefore it is suggested that during winter sawdust litter may be used for broiler rearing in Bangladesh.
