To study effects of 10% guar meal (GM)- included diets on productive performance, slaughter traits and some tibia measurements of broiler chicks, a total number of 180 Hubbard chicks were divided randomly into 5 treatments (36 chicks each), each treatment replicated 6 times of 6 chicks. Two iso-caloric and iso-nitrogenous diets in (starter (P₁), grower (P₂) and finisher (P₃) periods) including two levels of GM: Control diet without GM and 10% GM diet in overall trait periods P₁, P₂ and P₃ respectively, (T₁) or in P₁ (T₂); P₂ (T₃) or P₃ (T₄) only respectively. Results indicated that: Dietary 10% GM inclusion (T_1-4) significantly affected live body weight, body weight gain, feed conversion ratio and gave the lowest significant performance compared with control group. Dietary treatments did not affected feed consumption and chicks fed (T_1-3) diets recorded lowest values.  Dietary 10% GM inclusion (T_1-4) insignificantly affected carcass characteristics, carcass parts % and some tibia measurements. Generally 10% GM as replacement for soybean meal in starter, grower or finisher period diets as well as overall trait periods to broiler chicks has adverse effects on their productive performance under practical conditions and that further researches are needed to determine a more accurate level of Guar meal inclusion in broiler diets due to different factors such as periods rearing conditions and high viscosity of guar for better performance and carcass characteristics.
