Impact of calcium content and calcium to phosphorus ratio in diets for weaned pigs

Summary

This study was conducted to determine the influence of calcium (Ca) content and calcium to phosphorous (P) ratio on growth performance and mineral excretion in weaned pigs. Two experiments were conducted during a four or five week period using prestarter and starter diets with or without microbial phytase and varying in Ca and P content. The results are used to discuss Ca and P recommendations and consequences of a reduction in dietary Ca content.
