Author: Dr. John Cook and Rebekah Mast, World Wide Sires Access to relatively cheap and rapid genomic tests allows herds to individually test cows and heifers and to further enhance genetic gain through accurate identification, ranking females, and selecting the...
A smaller heifer inventory means reduced culling and turnover rates in the milking herd. This gives you the opportunity to milk more mature cows that produce at higher levels. Unfortunately, high-production mature cows come with a higher risk for mastitis and elevated Somatic Cell Count (SCS). So, how do you ensure you are selecting genetics for the right traits and indexes to facilitate healthier, longer-living cows?
In 2018, Kessenich Farms, LLC, a 600-cow Jersey and Holstein herd in DeForest, Wis. was faced with reproduction issues. Wade Kessenich recalls, "we...
Hang in there! Low inventory of native cattle (driven by drought and high input costs) and high beef demand have calf prices running red-hot right now. Sometimes, local markets can temporarily outcompete supply-chain prices simply based on transport cost. This won’t last forever, so here are some tips for how to sustain prices as long as possible.
The 2023 International All Things BLV Conference was hosted by Michigan State University. The agenda included speakers from six countries on three continents and sought to create community around this issue that would enable future collaboration.

Keys, wallet, cell phone are the essentials you won’t get far without, but with them, accomplish anything. What are the equivalent essentials for managing your herd?
With USDA estimating 94% of all dairy herds in the United States are infected with BLV; chances are your herd has it! BLV is incurable, but not unmanageable.
After 40 years in the industry, Retired CentralStar Consultant, Julie Ainsworth shares a few key lessons that routinely emerge and still exist as opportunities on dairies today.

There has been a long-standing definition of successful transfer of passive immunity, stated as 10 grams of IgG per liter of serum, 24-36 hours post colostrum feeding. The United States Department of Agriculture has raised the standard.
The progress made in reproductive performance on dairies is truly impressive. Today, it’s more commonplace to find herds with pregnancy rates over 30%.
What is PCR? Polymerase chain reaction is an advanced laboratory technique that amplifies DNA so it can be detected even when present in very, very...
The goal of reproduction has shifted from creating a replacement, to creating a fresh cow; the calf, or many of them, are simply the byproduct.
Whatever happens to a calf day 1, week 1 or month 1 of its life determines if it will live up to its genetic potential. This statement is true for both replacement heifers with tremendous milking…
Despite the wide-spread adoption of negative-dietary cation-anion differential close-up diets, an estimated 25-50% of newly freshened 2nd lactation and greater cows will experience…
