Semex Jerseys In The Driver's Seat!
Aaron Henderson, Semex US Jersey Specialist/Corporate Accounts Manager The Jersey breed is the fastest-growing dairy breed on the planet and as we accelerate into the next decade, Semexs Jersey program is truly in the drivers seat! While many of our competitors have focused on individual traits such as inbreeding, JPI, JUI and show type, Semexs Balanced Breeding philosophy and global sampling program have worked to provide a diversified lineup that meets the needs of dairymen everywhere. The Semex Jersey lineup is well suited to meet the needs of dairymen everywhere, whether they milk 50, 500 or 5,000 cows. Our genetics are poised to reach individual requirements and to help dairymen reach their profitability needs, efficiency goals and durability requirements. Reducing Inbreeding: Outcross ability is measured by EFI (Expected Inbreeding Coefficient) and bulls that have a 6.0 and lower EFI are widely considered to be genetically diversified. Semex has four bulls in its active line up under 6.0 EFI: 0200JE0103 Valleystream Julian; 0200JE0420 Pine Haven Senior; 0200JE0129 Bridon Jamaica; and 0200JE01310 Bridon Remake Comerica.

JUI (Jersey Udder Index): Semex is home to four of the top 20 ranked JUI sires, as much as anyone in the industry, with three ranking in the top six. Following the April 2009 proofs the breed average for JUI was 3.33, 18 Semex sires are above 3.33 JUI with our active lineup averaging 5.00 JUI.
