The influence of dietary phytase in pig nutrition is often investigated using pigs from 20 to 40 kg, but there are limited data to demonstrate that data obtained in young pigs can be extrapolated to pigs above 40 kg. Therefore, an experiment was conducted to determine effects of increasing phytase levels (0, 250, 500, 1,000, 2,000, and 4,000 phytase units) on phytate breakdown and nutrient digestibility of pigs throughout four productive phases (25 to 50 kg, 50 to 75 kg, 75 to 100 kg, and 100 to 125 kg). Results indicated that regardless of pig body weight, the digestibility of macro-minerals and most amino acids increased with increasing dietary phytase because of increased phytate breakdown.
