Four levels of vitamin-mineral supplementation were used (T1-control diet (60-30 IU of vit E for starter and growing diet, respectively, zero vit.
C, 80 ppm of inorganic Zn, 0.3 ppm of inorganic Se); T2-control diet 100 UI vit E and 300 ppm vit C-kg; T3control diet 40 ppm Zn and 0,3 ppm Se-kg; T4-control diet T2 and T3 levels) and two environments - thermoneutral and cyclic heat stress (TN and HS) from 14 to 35 days of age.
In the period when part of the birds was submitted to HS, from 14 to 35 days, it was observed lower feed intake (FI) and better feed conversion (FC) for HS birds receiving supple...
