Specific Appetite for Calcium in Broilers

An interesting paper.
In our broiler trials we found that dietary Ca-level has to be reduced at lower dietary P-concentrations. So, there is an interaction between Ca & P.

A very good and interesting paper about Calcium Specific Appetite of broiler.  If I am not mistaken, author Aaron Cowieson, used to work for Danisco and later on with AB Vista before joining his current position in University.

Thank you for the interest in this work about Calcium Specific Appetite of broiler. This is part of a large project to explore how digestible P and other dietary factors alter Ca appetite. We are using this model to explore Ca requirement but also with the objective of assessing the usefulness of post-pellet limestone addition which I believe will be beneficial on a whole host of metrics such as mill throughput, die wear, grit particle size selection and of course P digestibility, phytase effect and amino acid digestibility. Removing limestone from the diet appears highly beneficial. We have a paper on this topic in WPSJ 2011 (Dec) and another under review in BPS. Kind regards, Aaron.

Very interesting paper about Calcium Specific Appetite of Broiler. But I am quite sure, that , inthis result there is an interaction with an appetite for GRIT.
This could explained why there is an overconsumption of Ca with diet rich in Calcium...
Waiting your comment. Thak you
