The present investigation was conducted in Trujillo province, Peru, with the objective to determine the effect of three levels of seawater on productive parameters of broilers line Cobb 500. 240 birds were randomised in four treatments under a completely randomised design. They were: T0: Drinking water without seawater, T1: Sea water (\unitfrac[150]{ml}{gal}), T2: Sea water (\unitfrac[250]{ml}{gal}) and T3: Sea water (\unitfrac[350]{ml}{gal}). Highly significant statistical differences (p $<$0,01) were determinate  for the final  body weight  and the body weight gain.  The highest value were for T2 with 2,\mbox{64\,kg} and 2,59 kg; and lower values for  T0  with 2,\mbox{33\,kg} and 2,\mbox{28\,kg}. For total food consumption, highly significant statistical difference (p $<$0,01) was determined; still better statistically and numerically T2 (4,\mbox{45\,kg}); and worse T0 (4,\mbox{05\,kg}). In the food conversion rate was no calculated statistically significant difference (p$>$0,05),  but if numeric,  the best  value  was for T2 with 1,72 and  the worst for T0  with 1,78 .  In the mortality rate, T0, T1 and T2 had the higher values obtained with 1,\mbox{67\,\%} undifferentiated T3 statistically ($p > 0.05$). For the  productive efficiency index ,  T2 obtained the best value with 359,35 followed by T3, T1 and T0 respectively. For the B/C the best value is obtained T2 with 1,42 followed by 1,33; 1,37 and 1,38 for T0, T1 and T3 respectively. It is concluded that the addition of seawater into drinking water improves the productive parameters of chickens, T2 being the best treatment.
