The cows are producing 590 kg MS over a 305 day lactation, just 5% off the target of 625 kg. \r\n\r\nShe emphasises the importance of achieving high output where you are feeding high levels of concentrate.  \r\n\r\nFor more information: [https://www.ucd.ie/agfood/about/lyonsresearchfarm/lyonsdairyherd/](https://www.ucd.ie/agfood/about/lyonsresearchfarm/lyonsdairyherd/)[https://www.ucd.ie/agfood/about/lyonsresearchfarm/lyonssystemsresearchherdnotes/](https://www.ucd.ie/agfood/about/lyonsresearchfarm/lyonssystemsresearchherdnotes/)","thumbnail_url":"https://img.transistorcdn.com/FizPp2YqaNPbmx7kOdSSeqe3lGqQ33mTmLaxiS1YEus/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzEwMTc5LzE1ODgz/Mjc3MzMtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
