Abstract
Was carried an experiment with the objetive to evaluate the use of five levels of sugar (0, 4, 8, 16 and 32%) in substitution to the corn in the feed of broilers in the finishing phase. 320 chickens with 22 days of age, were randomly distributed for 20 box. The birds received water and feed ad libitum in all experimental period. The diets were isonetrogenous an isocaloric. The performance of the birds was evalueted. The birds were weigthed at 42 days of age and four birds of each experimental unit, two males and two females, were kept without food for a 12 hours. After this period the birds were slaughtered and eviscerated and carcass weight and yield as wells cuts yield were collected. Water, protein and body fat were observed. There was quadratic effect or the ration consumption, being 20.73 the point of maximum intake. The sugar influenced in a positive lineal way the weight and abdominal fat of the males. In the females negative lineal effect was for chest yield. With relations to the fat deposition and protein in the carcass, the levels of sugar didn´t influence in the males, in the females they caused positive linear effect for the fat body deposition
