The purpose of this study is to evaluate the use of phytase enzyme and organic minerals (P, Zn and Cu) and nitrogen (N) in the diet of pigs aimed at reducing the power of polluting waste. Four rations will be used: T1 - control treatment, T2 - organic mineral supplementation; T3 - phytase supplementation, T4 - organic mineral and phytase supplementation, in two experimental periods in function of the ambient temperature. The use of organic mineral and phytase in feed for pigs has a great potential for absorption improvement of nutrients by animals, reducing the excretion of minerals to the environment. The pigs will kept in cages growth of metabolism to collect excrements and urine. With the collections made, will estimate the amount and volume of excrements and urine produced, the concentration of nutrients (N and P) and micronutrients (Cu and Zn), dry matter and the daily consumption of diet. As the final results it is expected that the use of phytase and organic minerals provide better utilization of minerals and the reduction of nutrients excreted in pig manure, allowing the reduction of environmental impacts caused by swine.
