Lameness comes with a hefty price tag
When thinking about the effects of lameness, most managers typically consider the cost that goes into preventative measures or treatments such as trimming, bandages, blocks, and antibiotics, Eric Ronk shared recently.

Fresh cows run a daily marathon
Three weeks before and three weeks after calving, dairy cows experience massive changes in nutrient and micromineral demands. An energy deficit is common in this period and cows struggle to take in more energy than they deplete. Jessica McArt, DVM, compares this energy challenge to marathon runners in this article. Her analogy might help explain the effects of transition to a … [Read more...]

Declining cull cow numbers reflect shift from beef-on-dairy trend
Dairy producers are enjoying the cash flow improvements from the beef-on-dairy market, which is lowering the number of cull cows marketed and increasing the purchases of semen. The beef-on-dairy trend is also challenging the number of replacement dairy heifers available and prioritizing the purchase of gender-sorted dairy semen.

Repeat offenders should really be culled
Culling is a difficult thing for producers as they frequently fight to keep animals well, fed and producing. But the more chronically infected cows you keep in the herd, the more new infections you’ll have in the herd, shared Pam Ruegg, DVM. Source: Hoard’s Dairyman, September 28, 2023. Link. You don’t treat your way out of chronic cows. You’re not making money on these … [Read more...]
A look into acidosis and liver abcesses
Liver abscesses are nothing new to beef packers, but the condition is more common in crossbreds. The incidence is rising in native and dairy-influenced cattle. There is not one clear cause of liver abscesses. However, it is widely accepted that they are more common in animals that experience ruminal acidosis, according to Kendall L. Samuelson, PhD, PAS. Samuelson describes … [Read more...]

Cull cows, beef value now important for dairy profits
Cull beef cows were the topic of a recent post <Link>. For dairy producers, the value of cull cows and beef have moved from a rounding error to a critical component in profitability. This “beef value” can no longer be ignored, and producers that don’t make it part of their margin calculus may be leaving dollars on the table explains Will Babler. Source: Hoard’s … [Read more...]
Focus on heifers to improve reproduction success, costs
The main reproduction challenge on dairies now lies in the heifer herd, according to the University of Wisconsin-Madison’s Paul M. Fricke, PhD. He said, “Now that we’re raising fewer heifers, it’s more important to be better with them.” Fricke believes attention to reproduction is an important element in lowering the cost to raise a heifer to calving.

At 70 degrees F calves and cows start feeling the heat
A spring day in the 70s is often celebrated. Jackets get removed, grills get lit, golf clubs come out and cars get washed. But in the calf barn and calving pens, as well as in loafing lots, cattle start to move toward heat stress. Reminding producers that heat stress does not discriminate, Jimena LaPorta, PhD, shared the importance of keeping calves and cows cool. Source: … [Read more...]
Dairy industry contraction trend continues

Stimulating more milk fat production
Increasing milkfat and protein components of milk can raise the value of milk for producers. Milkfat comes from two sources. Preformed fat comes from fat present in the diet or body reserves. Other fat results from synthesis in the udder, and this is called de novo or “new” fat. Mike Hutjens, PhD, shared ways feeding and management can affect de novo fatty acid synthesis in … [Read more...]
