A standard starter diet was fed to 384 birds for 15 days. On day 15, they were weighed and randomly allocated to one of three treatment groups in a randomized complete block design, with eight replicate cages per treatment and 16 birds per cage. The birds in each treatment group were fed the PFD for 2, 3, or 4 days. There was an increase in growth performance (p &lt; 0.05) as the PFD feeding duration increased from 2 to 4 days. Although the relative dry weight of the ileum (mg\/100 g of body weight) decreased linearly (p &lt; 0.05) as the PFD feeding duration increased, the amount of dried ileal digesta (g\/bird) was not affected. The BEL of P was 110.2, 128.2, and 133.6 mg\/kg of dry matter intake in birds fed the PFD for 2, 3, and 4 days, respectively. Feeding a PFD to broiler chickens for 2, 3, or 4 days did not change P BEL.<\/jats:p>","DOI":"10.3390\/ani13111787","type":"journal-article","created":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T16:16:04Z","timestamp":1685204164000},"page":"1787","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effects of Different Feeding Durations on Ileum Length and Weight and Basal Endogenous Loss of Phosphorus in Broiler Chickens Fed a Phosphorus-Free Diet"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6236-6815","authenticated-orcid":false,"given":"Su Hyun","family":"An","sequence":"first","affiliation":[{"name":"Department of Animal Science and Biotechnology, Kyungpook National University, Sangju 37224, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3876-6488","authenticated-orcid":false,"given":"Changsu","family":"Kong","sequence":"additional","affiliation":[{"name":"Department of Animal Science and Biotechnology, Kyungpook National University, Sangju 37224, Republic of Korea"},{"name":"Department of Animal Science, Kyungpook National University, Sangju 37224, Republic of Korea"},{"name":"Research Institute of Horse Industry, Kyungpook National University, Sangju 37224, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2381","DOI":"10.3382\/ps.2013-03179","article-title":"Additivity of amino acid digestibility in corn and soybean meal for broiler chickens and White Pekin ducks","volume":"92","author":"Kong","year":"2013","journal-title":"Poult.
