This study was conducted to investigate the possibility of using two levels (15,30%) of Raw or soaked common Vicia sativa seed (cvs) in water for 72 h with changing the water every 12 h at room temperature or in acetic acid for 24 h at room temperature, in the broiler diet and their effects on the production performance and some biochemical blood parameters of broiler. The treatments were Included: 1) control diet , 2) 15% raw cvs seeds, 3) 15% water soaked cvs seeds,4)15% acetic acid1% soaked cvs seeds, 5) 30% raw cvs seeds, 6) 30% water soaked cvs seeds,7) 30% acetic acid1% soaked cvs seeds. The results showed that the birds fed diets contained treated cvs had significantly higher body weight compared to those received raw cvs seeds in their diets. However, the birds fed control diet had higher (P < 0.05) body weight over all treatments. Feed intake was significantly lower in birds fed raw or treated cvs seeds relative to control group. Feed Conversion ratio (FCR) was significantly poorer in birds fed 30% raw cvs seeds compared to other experimental groups. The mortality percentage was higher (P<0.05) in birds fed raw cvs seeds compare to control birds. Our statistical analysis showed that birds received 15 or 30% either water or acetic acid soaked cvs seeds had significantly higher production higher performance index than those received 15% or 30% raw cvs seeds. Nevertheless, birds in control group had higher production performance index relative to other experimental groups. Furthermore, the relative weights of liver, pancreas and heart were significantly higher (p< 0.05) in birds that received 30% raw cvs seeds than control group. From the selected serum biochemical parameters, the results of the current study showed that the bird groups fed on diets contained raw cvs seeds had significantly decreased (p<0.05) serum total protein, albumin and glucose concentrations ,While triglycerides and cholesterol concentrations in birds fed on either 15% or 30% raw cvs seeds were higher in compared to the other groups. With regard to the economic evaluation of experimental parameters, the results showed that there was no significant differences in the third treatment (15% water soaked cvs seeds) in comparison with control of both the value of the net profit and the net profit ratio contribution, recorded the lowest value of the net profit and the share of net profit in birds group fed diets contained 15% or 30% raw cvs seeds
