The study involved five crossbred commercial pigs (31.5 \u00b1 1.6 kg of body weight and 11 weeks of age; Landrace \u00d7 Yorkshire) and five mini-JINP (31.0 \u00b1 3.2 kg body weight and 20 weeks of age). The pigs were surgically equipped with a T-cannula at the end of ileum. Each pig breed was assigned to 5 dietary treatments in a 5 \u00d7 10 incomplete Latin square design with 10 periods. Four experimental diets were formulated to contain each of soybean meal, corn gluten feed, copra meal, and sesame expellers as the sole source of nitrogen. A nitrogen-free diet was also prepared to determine basal endogenous losses of CP and AA. No interaction between breed and feed ingredient was observed for the digestibility of CP and all indispensable AA. The SID of CP and all indispensable AA, except Arg, His, and Lys, did not differ between the two breeds of pigs. Prediction equations were developed for SID of CP and AA of commercial pigs using the SID values of mini-JINP: SID of CP (%) = (1.02 \u00d7 SID of CP in mini-JINP) \u2212 5.20 with r2 = 0.97 and p &lt; 0.05; SID of Lys (%) = (1.12 \u00d7 SID of Lys in mini-JINP) \u2212 9.10 with r2 = 0.98 and p &lt; 0.05; and SID of Met (%) = (1.08 \u00d7 SID of Met in mini-JINP) \u2212 4.27 with r2 = 0.96 and p &lt; 0.05. The digestibility for most AA in feedstuffs for commercial pigs can be estimated using data from mini-JINP.<\/jats:p>","DOI":"10.3390\/ani14182687","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T07:36:00Z","timestamp":1726472160000},"page":"2687","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of Amino Acid Digestibility between Commercial Crossbred Pigs and Mini-Jeju Island Native Pigs"],"prefix":"10.3390","volume":"14","author":[{"given":"Hyunwoong","family":"Jo","sequence":"first","affiliation":[{"name":"Department of Animal Science, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5632-5689","authenticated-orcid":false,"given":"John Kyaw","family":"Htoo","sequence":"additional","affiliation":[{"name":"Evonik Operations GmbH, Rodenbacher Chaussee 4, 63457 Hanau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2097-717X","authenticated-orcid":false,"given":"Beob Gyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1196\/annals.1334.015","article-title":"The miniature pig as an animal model in biomedical research","volume":"1049","author":"Smetana","year":"2005","journal-title":"Ann.
