Some of those effects may be related to methane emissions. The main driver of the decrease in methane is the reduction of youngstock\u201d<\/span><\/p>\n<\/blockquote>\n<p><strong>Different crossbreeding strategies<\/strong><br>A case herd was modeled in the study, with 200 purebred Holstein cows. The replacement rate for pure Holstein was 40.7%, for the different crossbreeding strategies, this was reduced to -6.3% for the two-way cross with RDM, -7.7% for the breeds under the ProCROSS concept, and -7.8% for the breeds marketed as VikingGoldenCross. Davis is convinced of crossbreeding\u2019s ability to reduce methane gas emissions at the farm level.<\/p>\n<blockquote>\n<p><span style=\"color: #13508a; font-size: 80%;\">\u201cIt can be part of the solution to face climate change and global warming challenges\u201d,&nbsp;<\/span><\/p>\n<\/blockquote>\n<p>The amount of methane per kg ECM is lower for both the two-way and three-way crosses, 4.2%,4.7%, and 6.6 % respectively. This is due to more healthy animals which live longer, and because fewer replacement heifers are required.<\/p>\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1249581209\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1280\" height=\"720\" src=\"https:\/\/simherd.com\/wp-content\/uploads\/2021\/05\/SimHerd-crossbred-methane-emission.jpg\" class=\"attachment-original size-original\" alt=\"\" srcset=\"https:\/\/simherd.com\/wp-content\/uploads\/2021\/05\/SimHerd-crossbred-methane-emission.jpg 1280w, https:\/\/simherd.com\/wp-content\/uploads\/2021\/05\/SimHerd-crossbred-methane-emission-300x169.jpg 300w, https:\/\/simherd.com\/wp-content\/uploads\/2021\/05\/SimHerd-crossbred-methane-emission-1024x576.jpg 1024w, https:\/\/simherd.com\/wp-content\/uploads\/2021\/05\/SimHerd-crossbred-methane-emission-768x432.jpg 768w\" sizes=\"auto, (max-width: 1280px) 100vw, 1280px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1249581209 {\n  width: 99%;\n}\n<\/style>\n\t<\/div>\n\t\n\n<div class=\"row\"  id=\"row-1973652950\">\n\n\n\t<div id=\"col-663683963\" class=\"col small-12 large-12\"  >\n\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\n<div class=\"row\"  id=\"row-1525708905\">\n\n\n\t<div id=\"col-1566926240\" class=\"col small-12 large-12\"  >\n\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\n<p>The full report was presented at the 71st EAAP Annual Meeting.
