Various physical and chemical properties of a mixture of pine shavings and sawdust (PS), kenaf core (KC), and whole chopped kenaf (WK) were determined in two successive broiler trials. In Trial 1, each material was placed into pens at a depth of approximately 11 cm. Litter from four replicate pens of each material was analyzed periodically for pH, N, and moisture. Body weight, feed consumption, breast blisters, manure burns, and litter caking scores were determined at the end of each trial. Prior to Trial 2, all Utter was turned and WK and KC were topdressed to attain similar litter weights in pens among treatments. In both trials, litter N and moisture increased at each sampling time. The WK and KC had higher moisture and N content throughout both trials. Litter pH increased throughout Trial 1 and reached a maximum value of 8.75 at the end of the trial. In trial 2, pH values were inconsistent but values over 8.0 were maintained. Litter type had no effect on body weight, feed conversion, breast blister, and manure bum scores in either trial. The % and KC exhibited significantly more caking than PS.
