The aim of present study was to determine the effect of slaughtering age, stocking density, gender, litter type, feeder type and poultry house type on the possible carcass defects such as broken bones, joint defects, breast blister, blood and bruise on breast, thigh and wing, breast bruise.The incidence of these carcass defects decreased with increasing age of broiler.The incidence of broken bones, joint defects and breast bruise increased with increasing stocking density.The incidence of joint defects and blood and bruise on thigh for female were significantly higher than those for male broiler.There are no significant differences among litter type in terms of the carcass defects of broilers.There are no significant differences among type of feeder and of house in terms of incidence of carcass defects measured in this experiment.Broken bones, bruising and other defects with carcass indicate adverse animal welfare and loss in product yield.This experiment determined the nature and incidence of defects contributing to the total. RESUMENEl propósito de este trabajo fue determinar el efecto de la edad de sacrificio, densidad de población, sexo, tipo de yacija, tipo de alimentador y tipo de gallinero sobre posibles defectos de la canal tales como huesos rotos, defectos articulares, erosiones en la pechuga, sangre y hematomas de la pechuga, muslo o alas, hematomas de la pechuga.La incidencia de estos problemas decreció al aumentar la edad del ave.La incidencia de huesos rotos, defectos articulares y hematomas en la pechuga aumentó con la densidad de población.Los defectos articulares y sangre o hematomas del muslo en las hembras fueron más frecuentes que en los machos.No se encontraron diferencias entre tipos de yacija, tipos de alimentador o tipo de gallinero.Huesos rotos, hematomas u otros defectos indican ausencia de bienestar y pérdidas económicas.Se determinó la contribución al total de la naturaleza e incidencia de defectos.
