Resumo: The main aim of this work was to study the effect of a diet with 15% of crude protein in early gestation on sow’s productivity. The study included 40 sows divided into two treatments, control (13% of crude protein) and test, with three repetitions. There was obtained an average piglets born alive per litter of 12,4 in control treatment and 13,51 in test (P>0,05). Pre-weaning mortality was 1,43 piglets per sow in control treatment and 1,16 piglets per sow in test treatment (P>0,05). There was a significant interaction between treatment and repetition for these parameters (P<0,05). The number of piglets weaned per sow showed no differences (P>0,05) with 10,89 piglets weaned/sow in control treatment and e 11,67 in test. The average birth weight was 1,46 kg/piglet in control treatment and 1,36 kg/piglet in test treatment (P<0,05). At 24 hours post-farrowing the average weight was 1,59 kg/piglet for control treatment and 1,49 kg/piglet for test treatment (P<0,05). However there were no significant differences on piglet’s weight at weaning (P>0,05) with 7,29kg/piglet in control treatment and 7,12 kg/piglet in test. The results suggest that the use of a diet with 15% of crude protein in early gestation has no benefit in the sow’s productivity
