Leucine oxidation was greater (P&lt;0.0001)\u00a0on d 17 than d 7 (28.8% vs. 21.8% of dose). Milk (5.4 kJ\/g; 5.2% crude\u00a0protein) production per piglet (656 g\/d vs. 940 g\/d) increased (p&lt;0.05) while\u00a0feed intake (kg\/d) tended (P&lt;0.10) to increase from early to late lactation. In conclusion, feed intake during lactation was insufficient to meet energy\u00a0requirements of these sows, based on measurements of energy metabolism.\u00a0Amino acid oxidation increased between early and late lactation, indicating\u00a0that more protein was being catabolized, probably to provide additional\u00a0energy. Therefore, the amino acid intake of these sows in late lactation was\u00a0insufficient to meet the demands for both protein synthesis and energy\u00a0utilization.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Energy metabolism and leucine oxidation were measured in lactating sows as\u00a0part of a long-term research program designed to redefine the protein, amino\u00a0acid, and energy requirements of modern, high producing sows.\u00a0Leucine \u00a0oxidation was used to estimate the catabolism of dietary and body protein for\u00a0energy.\u00a0The data showed that sows actively stored energy through lipogenesis during the\u00a0overnight period, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[18120,19],"tags":[1809,46,14,104],"class_list":["post-14992","post","type-post","status-publish","format-standard","hentry","category-ontario-pork","category-pork-insight-articles","tag-acid","tag-feed","tag-pig","tag-sow"],"_links":{"self":[{"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/posts\/14992","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/comments?post=14992"}],"version-history":[{"count":1,"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/posts\/14992\/revisions"}],"predecessor-version":[{"id":14994,"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/posts\/14992\/revisions\/14994"}],"wp:attachment":[{"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/media?parent=14992"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/categories?post=14992"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/prairieswine.com\/rsc\/wp-json\/wp\/v2\/tags?post=14992"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
