  <dc:description>&lt;p class="chapter-para"&gt;Duplicate lots of 2-g lake trout&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;(Salvelinus namaycush)&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;were fed a purified diet alone and with equimolar supplements of aminoethanol, methylaminoethanol, dimethylaminoethanol, choline or betaine. Supplements of choline, methyl- and dimethylaminoethanol significantly increased growth rate and reduced liver fat content, whereas aminoethanol and betaine did not. These results suggest that trout biosyn-thesize choline from methyl- and dimethylaminoethanol but not from aminoethanol or betaine.&lt;/p&gt;&lt;p class="chapter-para"&gt;In another experiment triplicate lots of 5-g trout were fed diets containing graded levels (0, 500, 1,000, 2,000 and 4,000 mg/kg) of choline. Growth results showed that the requirement for choline is no greater than 1,000 mg/kg of diet.&lt;/p&gt;</dc:description>
