The seven diets included different Ca sources of monocalcium phosphate (MCP), dicalcium phosphate (DCP), limestone, corn, soybean, wheat bran, and a Ca-free diet. All diets included 0.3% Cr&lt;sub&gt;2&lt;\/sub&gt;O&lt;sub&gt;3&lt;\/sub&gt; as a digestible marker as well. Hens were given &lt;i&gt;ad-libitum&lt;\/i&gt; access to feed and water. On day 3, fresh excreta and the ileal digesta were collected to analyze dry matter, Ca, and Cr&lt;sub&gt;2&lt;\/sub&gt;O&lt;sub&gt;3&lt;\/sub&gt; for digestibility analysis.Results: The Ca-free diets led to lower endogenous Ca losses at the ileum (p&lt;0.05) compared to the Ca-supplemented groups. Among the Ca-sourcing diets, MCP resulted in higher Ca losses, whereas corn-based diets showed relatively lower losses at the ileum. Calcium losses at the excretory site were not significant, although the ileal losses were markedly higher (p&lt;0.001), with diet-by-site interaction (p&lt;0.05). Apparent and standardized ileal Ca digestibility were higher for inorganic sources (MCP, DCP, limestone) than for plant-based sources, with DCP showing greater digestibility (p&lt;0.05).Conclusion: Inorganic Ca sources resulted in increased endogenous Ca loss and digestibility compared to plant seed-based layer diets, with these losses varying depending on the specific measurement sites.<\/jats:p>","DOI":"10.5713\/ab.25.0008","type":"journal-article","created":{"date-parts":[[2025,5,12]],"date-time":"2025-05-12T01:09:51Z","timestamp":1747012191000},"page":"2196-2202","update-policy":"https:\/\/doi.org\/10.5713\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessment
