In my viewpoint, you need to consider matrix value of Ca as well; otherwise, and as mentioned by others, Ca level in your diets incased that has adverse effect on Phytase. Below I added some considerations regarding Phytase and its matrix value. I hope this would be applicable. Factors affecting phytase activity
Mineral contentAlthough doubted in some literature, high level of dietary calcium has ...

For example when you add 1 kg ...

Introduction
Broiler diets consist basically of plant-derived ingredients. These feeds are characterized by having a large part of phosphorus in the form of phytate (Rostagno et al., 2011), which is poorly hydrolyzed by monogastric animals (Ravindran et al., 1995), which do not have a significant activity of enzymes such as phytase throughout the gastrointestinal tract.
However, in addition to c ...

Reply to Hamid Ibrahim Ismail;
The basis of any meaningful trial to compare sources of a single nutrient must start from a situation where that nutrient is the one limiting the performance parameter being monitored. In this situation we are evaluating methionine (more accurately M+C) and its impact on laying performance ie egg numbers, weight, and total mass. One should usually choose a point in t ...
