If you notice very few cows lying down during a farm call, it may be time to discuss the importance of sternal recumbency and recumbent rumination. Rick Grant says in a cow’s perfect world over 80 percent of rumination should occur when the cow is lying down. Resting with the sternum, or breastbone, on the ground and a slight left-side preference is the cow’s optimal resting … [Read more...]
Dairy industry posts lowest positive drug residue yet; sets new standard
Data from the National Milk Drug Residue Database website dates back to 1994 and represents 99 percent of the U.S. milk supply. A recent report showed only 424 out of 3,879,182 samples tested positive for an animal drug residue. This is lowest positive test rate in the history of the program and it is also the fifth consecutive year fewer than 600 milk samples tested positive … [Read more...]

Protocols without training aren’t enough
Having a well-written protocol is not sufficient for successful performance, writes Gonzola Ferreira.

Goals for first lactation dairy cows
We’ve shared considerable calving information in recent weeks. Healthy calves grow to be healthy cows. Rudimentary? Yes, but often unspoken. Calves and heifers that grow well and become productive cows is a target for every dairy farm. Mike Van Amburgh, PhD, shared some growth targets for dairy replacements, writes Abby Bauer. These include doubling a calf’s bodyweight … [Read more...]
It’s time to cull “cull cows” from our vocabulary
Cull cow weight and cull cow price have long been top factors in herd profitability. Making the decision to remove a cow from the herd is not always an easy one. Determining when the cow leaves and how is equally important. Contrary to what many believe, dairy cattle contribute much more to the beef industry than just ground beef. Changing the vocabulary from cull cow to … [Read more...]
Dairy markets don’t care about cost of production
The cost of nearly everything has gone up for dairy farmers and farm margins are being squeezed, writes Nate Donnay. What markets do care about is how much supply is available, and there is better news for farmers there. Understanding farm margin calculations can help veterinary teams and those calling directly on dairies to align services with opportunities to avoid costs … [Read more...]
Systemic inflammation in pre- and post-partum cows
Although excessive inflammation is bad, the results of a University of Guelph study revealed why some inflammation at calving is positive. The key is discovering the balance between healthy and excessive inflammation, according to Barry J. Bradford, PhD. Inflammation is needed to drive the birthing process, and we also think it’s important for aiding in the metabolic … [Read more...]
Paired housing in lieu of group housing
Group housing for dairy calves is not an easy system for all farms to implement. Dairies can still reap the benefits that come from raising calves in social groups by housing two calves together as a pair. I really like pair housing because we get a lot of the advantages of social housing without the detrimental effects of large groups. There is a lot of opportunity to modify … [Read more...]
Scouring calves still need milk
Calves must maintain adequate fluid and nutrient consumption while dealing with diarrhea. Jesse Goff, DVM, reminded producers, “If you withhold milk from the calf, the calf starves.

Dry cows need shade to thrive, increase lifetime production
When talking about environmental impact in dairies, most would think about carbon footprint or water quality. However, a University of Florida study determined it is most ideal to cool dry cows during the entire dry period to prevent milk loss. The same should be provided for bred heifers. Researchers found reduced dry matter intakes pre-calving and weaker immunity pre- and … [Read more...]
Target these goals for dairy steers
Dairy and crossbred steers are no longer thought of as subquality meat. However, there are some nuances to ensure quality.

Could artificial insemination become illegal?
Artificial breeding might become illegal should a ballot initiative in Colorado be enacted by the state’s citizens says Corey Geiger. He reviews the legislation that would call an animal, “any living, nonhuman creature.” The revised definition would then state, “. . . not limited to, a dog, a cat, a horse, livestock . . ,” says Geiger.

Cows aren’t to blame for most mastitis
Considering all factors that contribute to mastitis risk, cow factors only account for 20 percent of cases. The other 80 percent of infections are caused by humans, and more specifically, how the farm is managed. About 100 organisms can cause infections in the udders of dairy cows. When we have mastitis issues, we can’t really blame the cow. We have to look at ourselves … [Read more...]
Are farmers teaching cows bad habits?
It could be that slug feeding methods are forcing dairy cattle to eat too much too quickly causing a negative impact on the rumen environment. Management plays a role in feed bunk behavior, as farmers don’t have to just think about what feed animals consume, but also the manner in which they eat it.
