The objective of this study was to investigate the effects of different types of floor made from palm wastes in New Valley on growth performance, carcass traits, health status and economic efficiency of broiler. A total number of 180 one day old chicks of Cobb broiler strain were used. The study included six treatments, with three replicates for each treatment (3 pens); (wheat straw litter, wire net, plastic net, wooden slats, palm fiber net and palm stem slats floors). The achieved results showed that the floor types had significant (P≤0.05) effect on final body weight, body weight gain and feed conversion at final periods. Broilers reared on wheat straw litter, wooden slats and palm stem slats floors had significant superiority of body weight and gain over the broiler reared on wire net, plastic net and palm fiber mate floors. Also, feed conversion ratio of broiler reared on wheat straw litter, plastic net, wooden slats and palm stem slats floors had significant superiority values over the broiler reared on wire net and palm fiber mate floors. Birds reared on wheat straw litter, wooden slats and palm stem slats floors had significantly (P≤0.05) higher carcass percentage as compared to those of wire net floor. The lowest percentage of abdominal fat is recorded for broilers raised on wire net floor, plastic net and palm fiber net floors in comparison with those raised on wheat straw litter. Broilers raised on wheat straw and palm fiber net floors had a significantly (P≤0.05) higher bursa percentage than those of birds raised on wire net floor and palm fiber net floors. Broilers raised on wheat straw litter, wooden slats and palm stem slats floor had significantly (P≤0.05) lower leg problems than those of birds raised on wire net floor and palm fiber net floors. The difference in body measurements and breast blisters were not significant among the different floor types. Regarding, the economic efficiency, it could be concluded that wooden slats and palm stem slats floors best being used for managing broilers. In addition, palm stem slats (having less health problems than other floor) are recommended in New Valley as a safe and economical alternative floor for any floor.
