Effect of diet phase change, dietary Ca and P level and phytase on bird performance and real-time gizzard pH measurements

In this study, a novel capsule technique was used to capture real-time pH readings from the gizzard over several hours, in response to different dietary treatments.1. The first experiment was a preliminary study into capsule administration and pH recordings using 9 male Ross 308 broilers from 20 d. In the second experiment, broilers (576) were fed in two phases (0–21 and 21–42 d) with 4 treatment groups; low and adequate Ca and AvP diets with...
