reach sufficient bodyweight to be moved to a feedlot for finishing. Pre-feedlot, their diet is composed mainly of grass, with little or no concentrates. On arriving at the feedlot, calves need to be transitioned to a high-concentrate diet, a process that requires the adaptation of rumen bacterial populations. It’s considered this change takes a minimum of 14 days; to achieve optimal rumen bacterial balance and avoid ruminal disorders, such as acidosis.</p> <p> </p> <p>Organic acids are normal metabolites of ruminal fermentation, where rumen bacteria metabolise carbohydrates to organic acids (VFA and lactate). Volatile fatty acids (VFA) are used by the animal as a primary energy source. Because the goal of the feedlot phase is to finish cattle on a high-grain diet, after their previous forage-based regime, a period of transition is required to change the animal’s eating behaviour. </p> </div> </div> <div class="wpb_single_image wpb_content_element vc_align_right"> <div class="wpb_wrapper"> <div class="vc_single_image-wrapper vc_box_border_grey"><img decoding="async" class="vc_single_image-img " src="https://phileo-lesaffre.com/wp-content/uploads/2020/06/Picto-beef-192x285-1-120x178.png" width="120" height="178" alt="picto beef" title="Picto-beef-192x285" loading="lazy" /></div> </div> </div> </div></div></div><div class='q_elements_item ' data-animation='no' data-item-class='q_elements_holder_custom_486901' style='background-image: url(https://phileo-lesaffre.com/wp-content/uploads/2020/06/Beef-860x600-1.jpg);background-position: center;background-size: cover;vertical-align:middle;text-align:left;'><div class='q_elements_item_inner'><div class='q_elements_item_content q_elements_holder_custom_486901'></div></div></div></div></div></div></div></div></div><div class="vc_row wpb_row section vc_row-fluid " style=' text-align:left;'><div class=" full_section_inner clearfix"><div class="wpb_column vc_column_container vc_col-sm-12"><div class="vc_column-inner"><div class="wpb_wrapper"><div class='q_elements_holder two_columns responsive_mode_from_768' ><div class='q_elements_item ' data-animation='no' data-item-class='q_elements_holder_custom_120020' style='background-color:#ad1a22;vertical-align:middle;text-align:left;'><div class='q_elements_item_inner'><div class='q_elements_item_content q_elements_holder_custom_120020' style='padding:5% 2% 5% 10%'> <div class="wpb_text_column wpb_content_element "> <div class="wpb_wrapper"> <h2 class="feed4"><span style="color: #ffffff;">Bacterial changes</span></h2> </div> </div> <div class="wpb_single_image wpb_content_element vc_align_left vc_custom_1592227932921"> <div class="wpb_wrapper"> <div class="vc_single_image-wrapper vc_box_border_grey"><img decoding="async" class="vc_single_image-img " src="https://phileo-lesaffre.com/wp-content/uploads/2020/05/Dash-50x25.png" width="50" height="25" alt="Phileo dash" title="Dash" loading="lazy" /></div> </div> </div> <div class="wpb_text_column wpb_content_element vc_custom_1592494449864"> <div class="wpb_wrapper"> <p><span style="color: #ffffff;">Microbes in the rumen of cattle on a forage-based diet are primarily comprised of those most effective at breaking down the fibres in forage.
