RESUMO

The pork production with low cost, safe and with high quality, identified with the consumer exigencies, and produced with reduced pollution capacity are a current objectives of the segment. There phytase enzyme utilization with the goal to improve the availability of the phytic phosphorus of the grain and the other minerals, reducing losses and ambiental damage is growing. To contrast there is a little information about the effect of the phytase on the pork quality, especially preserving the lipidic oxidation risks, considering the recognized action of the phytic acid as a potent antioxidant. This work had the objective to evaluate the high inclusion of defatted corn germ meal (40%) on the swine feeding rations, a co-product of the corn processing, that has a high phytic acid level, associated with different concentrations of phytase (0; 500; 1000 and 1500 PPU) on the pig performance, carcass characteristic, meat quality, serum parameters and faecal levels of iron, phosphorus and calcium. The results showed that the 998,24 PPU provided the best utilization of the phosphorus of the diet, but there was no damage or positive effects of the level of phytase on the other evaluated parameters, including the negative effect on the meat quality.
