Dairy cows were fed pellets with 0% (0PEL), 0.75% (0.75PEL), 1.5% (1.5PEL), or 3.0% (3PEL) of AME (Experiment 1). Furthermore, dairy cows were fed 0% (0AM), 5% (5AM), 15% (15AM), or 25% (25AM) of AM in maize silage (Experiment 2). Data sampling period (21 days) of ruminal CH\u2084 and nitrogen (N\u2082), carbon dioxide (CO\u2082), and hydrogen (H\u2082) gases (% vol) was conducted after the adaptation period (14 days) for each experiment. \n&lt;b&gt;Results:&lt;\/b&gt; Enteric CH\u2084 was not affected by AME inclusion, but AM inclusions affected CH\u2084, except for CH\u2084 (% vol per cow per day). The inclusions of 25AM decreased CH\u2084 per nutrient intake (kg\/day), such as dry matter (DM), organic matter (OM), crude protein, acid detergent fiber (ADF), and neutral detergent fiber (NDF). In addition, there was a linear and quadratic AM inclusion effect on CH\u2084 per intake of nutrients, including DM, NDF, ADF, and OM. \n&lt;b&gt;Conclusion:&lt;\/b&gt; Enteric CH\u2084 was not affected by AME but was decreased by AM in dairy cows.<\/jats:p>","DOI":"10.5455\/javar.2025.l962","type":"journal-article","created":{"date-parts":[[2025,11,6]],"date-time":"2025-11-06T17:46:08Z","timestamp":1762451168000},"page":"1030","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of enteric methane production in dairy cows fed &lt;i&gt;Acacia mearnsii &lt;\/i&gt;"],"prefix":"10.5455","volume":"12","author":[{"given":"Lindokuhle","family":"Mhlongo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ignatius","family":"Nsahlai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Journal of Advanced Veterinary and Animal Research"],"original-title":[],"link":[{"URL":"https:\/\/www.bibliomed.org\/fulltextpdf.php?mno=193579","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:02:53Z","timestamp":1791482573000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.bibliomed.org\/?mno=193579"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.5455\/javar.2025.l962","relation":{},"ISSN":["2311-7710"],"issn-type":[{"value":"2311-7710","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]}}}
