Experimental diets included: (i) inorganic\n                    phosphate supplements (monocalcium phosphate [MCP], dicalcium phosphate [DCP],\n                    monosodium phosphate [MSP]); (ii) plant-based phosphorus sources (corn [CRN],\n                    soybean meal [SBM], and wheat bran [WB]); and (iii) a phosphorus-free diet\n                    (P-free). Measurements were collected from the ileum and excreta over three days\n                    with six replicates per dietary treatment and four hens per cage, under\n                        ad libitum feeding conditions. The study demonstrated\n                    interactions (p &lt; 0.05) between diet type and sampling\n                    locations on endogenous phosphorus losses. Higher endogenous phosphorus losses\n                        (p &lt; 0.05) were observed in the excreta of hens fed\n                    P-free, MCP, DCP, MSP, and WB diets. Increased endogenous P losses in the ileum\n                        (p &lt; 0.05) were noted in hens-fed CRN, SBM, and WB diets\n                    compared to inorganic phosphate supplement diets. The AID and SID of P were\n                    significantly lower (p &lt; 0.05) in the CRN diet compared to\n                    SBM, WB, MCP, DCP, and MSP diets. Among inorganic phosphate supplements, MCP\n                    exhibited the highest SID of P, while for plant-based sources, SBM and WB\n                    demonstrated higher SID values than CRN. The AID of P was higher\n                        (p &lt; 0.05) in hens fed the MCP diet compared to SBM and\n                    WB diets, but diet type did not affect the AID of dry matter (p\n                    &gt; 0.05). In conclusion, diet type and sampling location influence endogenous\n                    P losses in laying hens, with differences between ileal and excreta\n                    measurements. The results highlight the variability in P bioavailability among\n                    plant-based and inorganic phosphorus sources, emphasizing the need to account\n                    for ingredient-specific P digestibility when formulating diets for optimal P\n                    utilization.<\/jats:p>","DOI":"10.5187\/jast.2025.e15","type":"journal-article","created":{"date-parts":[[2025,4,14]],"date-time":"2025-04-14T04:18:12Z","timestamp":1744604292000},"page":"532-540","update-policy":"https:\/\/doi.org\/10.5187\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Endogenous
