Effect of squash seed meal (Cucurbita moschata) on broiler performance, sensory meat quality, and blood lipid profile

in this experiment, 240 cobb-500？ broilers reared from1 to 49 days, and distributed according to a completely experimental randomized design with four treatments of four replicates each in order to evaluate the effect of the dietary inclusion of 0, 33, 66 or 100 g/kg of squash seed meal (ssm) (cucurbita moschata) on the performance, carcass yield, serum lipid profile and sensory meat quality of broilers. significant differences (p<0.05) were detected in performance, carcass weight, weight and breast yield, and leg weight. the best results were obtained with 33 and 66 g/kg as compared to the control diet and 100 g ssm /kg. abdominal fat decreased with the inclusion of 66 and 100 g ssm / kg, but the sensory quality of breast and thighs was not affected by the inclusion of ssm. the serum levels of total cholesterol, very low density (vldl) and low density (ldl) lipoproteins, triglycerides, glucose and atherogenic index decreased with the inclusion of 100 g/kg of ssm, except for high density lipoproteins (hdl), which increased. the inclusion of 0, 33, 66 and 100 g/kg of ssm in broiler diets, partially replacing soybean meal and vegetable oil, improved live performance and edible portions yield. in addition, abdominal fat and serum levels of harmful lipids were reduced, whereas serum levels of beneficial lipids increased. there was no effect on meat sensory quality.
