The bottom line is that maintenance costs rise as mature size increases, but it&rsquo;s not a 1:1 relationship. In fact, the general rule of thumb is that maintenance costs are calculated by taking mature size to the .7 power.</p></div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/my-view-country"> My View From The Country</a></li> </ul></div><p><a href="http://beefmagazine.com/blog/there-no-magical-cow-size-guarantees-profitability" target="_blank">read more</a></p> http://beefmagazine.com/blog/there-no-magical-cow-size-guarantees-profitability#comments Selection Tools Beef Quality Cattle Marketing Beef Industry Products My View From The Country Thu, 13 Mar 2014 20:34:00 +0000 72311 at http://beefmagazine.com U.S. Beef Herd Is Mostly Black But Changing Slightly http://beefmagazine.com/cattle-genetics/us-beef-herd-mostly-black-changing-slightly <div class="node-body article-body">An exclusive BEEF survey indicates that while the trend for the cowherd to be straightbred and black continues, the genetic makeup of the nation’s cowherd is changing ever so slightly.</div> <div class="og_rss_groups"></div><p><a href="http://beefmagazine.com/cattle-genetics/us-beef-herd-mostly-black-changing-slightly" target="_blank">read more</a></p> http://beefmagazine.com/cattle-genetics/us-beef-herd-mostly-black-changing-slightly#comments Cattle Genetics Tips For Profit Wed, 29 Jan 2014 11:00:00 +0000 70411 at http://beefmagazine.com Do Beef Cattle Have A Biological Limit To Productivity? http://beefmagazine.com/cattle-genetics/do-beef-cattle-have-biological-limit-productivity <div class="node-body article-body">Per-animal production may be approaching the limits of beef cattle’s ability, while straining the outer limits of the industry’s economic model. </div> <div class="og_rss_groups"></div><p><a href="http://beefmagazine.com/cattle-genetics/do-beef-cattle-have-biological-limit-productivity" target="_blank">read more</a></p> http://beefmagazine.com/cattle-genetics/do-beef-cattle-have-biological-limit-productivity#comments Cattle Industry Structure Feedlots Business Cattle Genetics Tips For Profit Mon, 27 Jan 2014 16:27:00 +0000 70341 at http://beefmagazine.com
