In total, 84 1-day-old male broiler chickens (Ross 308) were used for the experimental study. During the first phase of the experiment (1\u201316 d), all birds in each treatment were fed with a corn\u2013soybean meal reference diet. After this time, the first treatment (control) was still fed the reference diet. In the second and third treatment, 50% of the reference diet was replaced with 50% pea seeds. In addition, the third treatment was supplemented with exogenous amylase. Animal excreta were collected on 21 d and 22 d of the experiment. The birds were sacrificed at the end of the experiment (23 d), and samples of ileum content were collected. The experimental results showed that the exogenous addition of amylase significantly improved (p &lt; 0.05) the apparent ileal digestibility (AID) of the crude protein (CP), starch, and dry matter (DM) of pea. In addition, an improvement in the AID of essential amino acids in pea seeds (except Phe) was observed. The trend in the AMEN values was also noted (p = 0.076). It can be concluded that supplementation with exogenous amylase improves the nutritional value of pea seeds in broiler chicken nutrition.<\/jats:p>","DOI":"10.3390\/ani13050816","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T03:01:01Z","timestamp":1677207661000},"page":"816","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Effect of Exogenous Amylase Supplementation on the Nutritional Value of Pea (Pisum sativum L.) for Broiler Chickens"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9989-9340","authenticated-orcid":false,"given":"Katarzyna","family":"Perz","sequence":"first","affiliation":[{"name":"Department of Animal Breeding and Product Quality Assessment, Poznan University of Life Sciences, S\u0142oneczna 1, 62-002 Suchy Las, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3638-4192","authenticated-orcid":false,"given":"Sebastian Andrzej","family":"Kaczmarek","sequence":"additional","affiliation":[{"name":"Department of Animal Nutrition, Poznan University of Life Sciences, Wo\u0142y\u0144ska 33, 60-637 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"Nowaczewski","sequence":"additional","affiliation":[{"name":"Department of Animal Breeding and Product Quality Assessment, Poznan University of Life Sciences, S\u0142oneczna 1, 62-002 Suchy Las, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron Joell","family":"Cowieson","sequence":"additional","affiliation":[{"name":"DSM Nutritional Products, 4303 Kaiseraugst, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1772-7997","authenticated-orcid":false,"given":"Marcin","family":"Hejdysz","sequence":"additional","affiliation":[{"name":"Department of Animal Breeding and Product Quality Assessment, Poznan University of Life Sciences, S\u0142oneczna 1, 62-002 Suchy Las, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"567","DOI":"10.3923\/ijps.2010.567.573","article-title":"Evaluation of Faba Beans, White Lupins and Peas as Protein Sources in Broiler Diets","volume":"9","author":"Nalle","year":"2011","journal-title":"Int.
