The objective of this study was to evaluate the productive performance of growing pigs fed reduced amino acids dietsby  the  use  of  phytase.  During  63  d  (three  21  d  feeding  phases),  a  total  of  96  pigs  in  two  blocks  (consecutivefarrowing groups), of an average initial weight of 42.7 ± 4.58 kg, were randomized to six treatments which consistedof a  2  x 3  factorial arrangement  (conventional  diet, a positive control= CP  or reduced in amino acids  by the  additionof  phytase,  a  negative  control=  CN)  and  (3  leads  of  phytase:  0,  Phytase  A  or  Phytase  B).  Weekly  feed  intake  wasrecorded.  At  start  and  the end  of  each  feeding-phase  pigs  were  weighed  and  fat and  muscle  depths  were  measuredusing  real  time  ultrasound.  At  the  end  of  each  feeding  phase,  blood  samples  were  drawn  to  determine plasma  ureanitrogen.  Aside  for  final  feed  efficiency,  which  was  slightly improved  by  phytase  (P 0.15).  On  the  efficiency  of  utilization  ofnutrients, there was an obvious effect by level of digestible lysine (P<0.03), better in the lower lysine diets, althoughplasma  urea  nitrogen  levels  were  the  same  for  all  treatments  (P<0.18).  In  conclusion,  a  slight  reduction  in  theconcentration of amino acids, nor the addition of phytase to diets for pigs from 40 kg of body weight affect productiveperformance  due  to  the  inherent  variation  of  the  apportion  and  of  the  requirements
