[QUOTE="IluvABbeef, post: 918838, member: 3739"] I would think so, DJ. The article had had the heifers on a more roughage-type diet with higher fiber over protein/energy feedstuffs which made them reach a mature weight more slowly than what is usually done to grow replacement heifers. All they (John and Adele Popp of Erickson, MB) did was restrict the heifers' rate of gain in order for them to reach a smaller terminal weight. And these were Simmental-Angus heifers, not just british-bred heifers, so these heifers, on a normal replacement feeding program, would gain more and grow into larger heifers than the Popps had them to do, simply by limiting supplementation. Now how this factors into the puberty part of the equation is where it gets a little interesting. The article states this: I believe this paper may have some relation to the quoted article above: [url=http://www.ianrpubs.unl.edu/epublic/live/rb350/build/rb350.pdf]http://www.ianrpubs.unl.edu/epublic/liv ... /rb350.pdf[/url] So there you go. All the whole thing was about limiting feed for replacement heifers was to save on feed, nothing to do with anything affecting puberty, conception rates nor gestation. [/QUOTE]
