The effects of 12 different diets which regulated 0.1-0.7 mol na/k ratio and 176-422 meq/kg dietary electrolyte balance,deb,(na+k-cl) were investigated on growth,blood gases,hematological variables,biochemical parameters and carcass traits in broiler chickens. two-day old ross-308 male chicks (n=180) having individual thirty replicates for 6 groups were used and the study lasted 42 days in the experiment. the s group diet was based on corn and soybean meal and 0.25% salt. this group diet was accomplished by adding 1-0.5% nh 4cl as a1 and a2 of anionic groups and 0.5-1-1.5% nahco 3 as c1,c2 and c3 of cationic groups in starter and grower phases,respectively. increasing na/k and deb of the diets had no effect on live weight,body weight gain and feed per gain in 0-42 days (p>0.05). blood ph quantitatively increased in s,c1 and c2 groups (p<0.05). a1,a2 and s groups of po 2 levels were higher than those of cationic groups (p<0.05),(r 2=0.59). the values of hco 3 -,hco 3std,tco 2,be ecf,be(b),hct and thbc were lower anionic groups than cationic groups (p<0.05),(r 2=0.63-0.82). so 2c level was the lowest in c1 group (p<0.05). anion gaps of the broilers were calculated as 7.97-20.84 meq/l. ionized calcium was quantitatively the highest in a1 group. hot carcass and abdominal fat were not afected by the experimental diets with varying na/k and deb (p>0.05). based on the results of this study,anionic diet such as a1 or 0.1 of na/k ratio and 212 meq/kg of deb could be fed for broilers in case of insufficient ca. in normal case,it is concluded that c1 and c2 of diets or 0.3-0.5 of na/k ratios and 259-344 meq/kg of deb were appropriate for broilers.
