Arg and Met can enhance antioxidant and intestinal cell proliferation activity, thus supplementing them in diets might alleviate epithelial damage and correct the reduced AA digestibility. The effect of adding extra l\u2010Arg and dl\u2010Met to diets on the apparent (AID) and standardised ileal digestibility (SID) of AA was analysed in a 10\u2010day experiment conducted with 10 ileal\u2010cannulated HS pigs (25.3\u2009\u00b1\u20092.4\u2009kg body weight). The pigs were divided into two treatments: Control, wheat\u2010soybean meal diet supplemented with l\u2010Lys, l\u2010Thr, dl\u2010Met\u00a0and l\u2010Trp; and control diet plus 0.20% l\u2010Arg and 0.20% dl\u2010Met (Arg\u2009+\u2009Met). Following an 8\u2010day diet adaptation period, ileal digesta was continuously collected for 12\u2009h, starting at 0700, on Days 9 and 10. All pigs were daily exposed to 29.6\u201336.1\u00b0C; ileal temperature was continuously monitored at 15\u2010min intervals. Feed was provided twice a day. The ileal temperature ranged from 40.3 to 41.5\u00b0C. Daily ileal outflow of His, Ile, Leu, Phe, Thr, Ser\u00a0and Tyr decreased (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), and that of Arg, Val\u00a0and Pro tended to decrease (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.10) in the Arg\u2009+\u2009Met pigs. The AID of Arg, His, Met, Thr\u00a0and Tyr, and the SID of His, Met, and Thr increased in pigs fed the Arg\u2009+\u2009Met diet (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Thr and Val had the lowest AID values whereas Arg, Met, and Lys had the highest values. Arg (<jats:italic>r<\/jats:italic>\u2009=\u20090.64) and Met (<jats:italic>r<\/jats:italic>\u2009=\u20090.84) intake were highly correlated with their AID values; Met intake was highly correlated with its SID value (<jats:italic>r<\/jats:italic>\u2009=\u20090.72). Valine and Arg had the lowest whereas Arg had the highest SID values. In conclusion, supplementing l\u2010Arg and dl\u2010Met above the requirement decreases the ileal outflow of several AA, and increases the AID and SID of some essential AA in HS pigs.<\/jats:p>","DOI":"10.1111\/jpn.13793","type":"journal-article","created":{"date-parts":[[2022,12,1]],"date-time":"2022-12-01T15:04:53Z","timestamp":1669907093000},"page":"859-866","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Apparent and standardised ileal amino acid digestibilities in heat\u2010stressed pigs fed wheat\u2010soybean meal diets supplemented with l\u2010arginine and dl\u2010methionine"],"prefix":"10.1111","volume":"107","author":[{"given":"Alan","family":"Valle","sequence":"first","affiliation":[{"name":"Instituto de Ciencias Agr\u00edcolas Universidad Aut\u00f3noma de Baja California Mexicali Baja California M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3713-8305","authenticated-orcid":false,"given":"Miguel","family":"Cervantes","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias Agr\u00edcolas Universidad Aut\u00f3noma de Baja California Mexicali Baja California M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6721-2257","authenticated-orcid":false,"given":"Adriana","family":"Morales","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias Agr\u00edcolas Universidad Aut\u00f3noma de Baja California Mexicali Baja California M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilberto","family":"Castillo","sequence":"additional","affiliation":[{"name":"Complejo Regional Centro, Ingenier\u00eda Agron\u00f3mica y Zootecnia Benem\u00e9rita Universidad Aut\u00f3noma de Puebla Puebla M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Estela","family":"Montoya","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias Agr\u00edcolas Universidad Aut\u00f3noma de Baja California Mexicali Baja California M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jollie Caroline","family":"Gonz\u00e1lez\u2010Vega","sequence":"additional","affiliation":[{"name":"Evonik Operations GmbH Hanau\u2010Wolfgang Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John K.","family":"Htoo","sequence":"additional","affiliation":[{"name":"Evonik Operations GmbH Hanau\u2010Wolfgang Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ernesto","family":"Avelar","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias Agr\u00edcolas Universidad Aut\u00f3noma de Baja California Mexicali Baja California M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,12]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"2000","volume-title":"Official methods of analysis","author":"Association of Official Analytical Chemists (AOAC)","year":"2006"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.00018.2006"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtherbio.2017.06.008"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1113\/eph8602102"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0003-2697(02)00048-9"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.4141\/cjas79-081"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.nutr.23.011702.073120"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/112_2015_24"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1877-1823(09)70132-8"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0064412"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.2001.6164"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2008-1624"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0007114508911612"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1093\/jas\/skz037"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1093\/jas\/sky044"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/jpn.12267"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1093\/jas\/skab179"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/jpn.12161"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2015-9393"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2016-0571"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.2527\/1994.722344"},{"key":"e_1_2_8_23_1","volume-title":"Norma Oficial Mexicana.
