Abstract
112 crossbred (Large White .times. Landrace) growing-finishing swine (27 to 95 kg) were used to study the effect of different levels of feed restriction on performance. A 7 .times. 2 factorial randomized block design with two replicas was used. The feed restriction levels were: ad libitum (control); 3 + 1; 4 + 1; 5 + 1; 5,5 + 1,5; 6 + 1 (where the first number was time on days with ad libitum feeding and the second number, the time on days of fast) and 80% of ad libitum feeding. The feed restriction 3 + 1 and 80% of ad libitum resulted on lower daily gain. There were no differences among the other treatments. The highest and lowest feed intakes were for restriction levels 6 + 1 and 80% of ad libitum respectively. There were no differences among the other treatments. The best feed gain ration was for animals on 80% of ad libitum and there were no differences among the other treatments.
