A total of 300 one day old chicks were obtained from two broiler breeder flocking ages (26 and 43 weeks) and housed on three types of litter: sand, wheat straw and wood shavings. Body weigh, mortality, feed consumption and feed conversion were measured. At time of slaughter carcasses grading, the of breast blisters, incidence of scabby hip syndrome, vent scabs and sores were measured. At 42 days of age 5 birds of each replicate were visually assessed for the middle claw on both feet was measured. Using sand as litter materials resulted in significant increase in body weight and the best for feed efficiency than the two other treatments, while it had not significant effect on mortality rate. Breeder hen age had a significant effect on body weight at all ages and had no effect on mortality rate. Birds which were reared on wheat straw consumed significantly less than those reared on sand and wood shavings. Using sand led to lowering liver, spleen, heart and bursa of fabricus body weight ratio, gizzard, heart adrenal body weight ratio and increasing thyroid activity as thyroid body weight ratio. Birds reared on sand had the shortest significant right and left claw length compared to those reared on either wheat straw or wood shavings. The incidence of vent scabs, scabby hip syndrome, sores and breast blisters were higher of birds grown on wheat straw and wood shavings compared to those reared on sand litter. Rearing broiler chicks on sand resulted in lowering total cost compared to the chicks reared on wood shavings and higher compared to which reared on wheat straw. It was higher both net revenue and economic efficiency comparing to those reared on either wheat straw or wood shavings.
