| 释义 |
Mepron is the brand name for a time-released, rumen-protected DL-Methionine capsule for dairy cattle. It is a registered trademark of Evonik Industries. ProductThe product is a 1.8 mm x 3 mm, nearly-white cylindrical granule. The granules are free-flowing, and nearly insoluble in water. The product is nearly dust-free, and has a high level of durability.[1] It is coated in ethylcellulose, a rugged and durable fiber. Mepron is also heat- and pH-tolerant, and has a long shelf life.[2] UsesDairy-herd milk production may be limited by the amino acid methionine; therefore, the amino acid is included in cattle rations to provide a well-balanced diet.[3] Normally a cow receives 10-20 grams of Mepron per day, depending on performance and ration composition.[4] According to a 2006 study, results "suggest that RPM [rumen-protected methionine] may be needed to improve milk production in Holstein cows with a mean production of 35 kg d-1 milk, fed with [a] diet based on alfalfa and corn silage. The optimum response was obtained with [the] addition of 16 g d-1 of ruminally protected methionine. Further studies are needed to determine if cows may respond to lysine supply once the methionine requirements are met."[5] SafetyMepron can be handled safely and is non-toxic, according to EU chemicals legislation.[6] References1. ^http://www.makemilknotmanure.com/technical.php 2. ^{{cite web |url=http://www.zayand.com/Specifications.htm |title=Archived copy |accessdate=2010-12-27 |deadurl=yes |archiveurl=https://web.archive.org/web/20110718151420/http://www.zayand.com/Specifications.htm |archivedate=2011-07-18 |df= }} 3. ^Patton, R.A.
