Herd Management
Don’t Just Do Something – Stand There by Dr. Brian Reed
“Doc, I have a cow that just pushed out her uterus while I was treating her for milk fever. I still have her head tied back to her leg. Should I just push it back in?” These were the first words I heard a few weeks ago at the start of a busy day. I assured my client I would leave shortly to attend to his cow, but also explained to him a few tips to help him correct the situation safely and effectively. While preparing to leave home, my mind flashed back several decades to a lesson taught to me by one of my professors at the University of Minnesota College of Veterinary Medicine.

What to Do While Waiting for the Vet by Dr. Charlie Gardner
Dr. Reed mentioned some strategies you can take to help things to go well in the case of a prolapsed uterus. This month I will follow up on that theme with some other situations. All of them follow his primary point: take a minute or two to think things through, and then take whatever action makes sense. Read the full column.

It Takes Time to Recover From Heat Stress by Dr. Charlie Gardner
As you read this, we may still be having some hot days, with a little relief at night. But we know
that cooler weather is not far away. Unfortunately, the negative effects of heat stress linger on
for at least two months after the temperatures drop. I can recall many of my clients being
concerned that production and reproduction were below expectations well into November and
December. Read the full column.

Common Toxins for Dairy Animals and How to Take Precautions by Dr. Charlie Gardner
There are few things on a dairy farm as shocking, and as discouraging, as seeing a group of animals suddenly become ill and then start dying right in front of your eyes. This scenario can and does happen when animals are exposed to certain toxins. You should know the common poisons that are often present on dairy farms and take extra care that your cows and youngstock do not have access to them. Read the full column.

Fresh Cow Health
Aspirin Use in Fresh Cows by Caroline Arrowsmith
Coming from a small dairy farm, fresh cow management is not a major daily task. However, last
summer during my time as an on-farm intern at Pine Tree Dairy in Marshallville, OH, I learned
the true importance of closely managing your fresh cows. Properly caring for your fresh cows
sets them up for successful and profitable lactations. On the other hand, diminishing the
importance of fresh cow care can lead to milk loss, increased incidence of disease, and possibly
culling. Read the full column.

Monitoring Fresh Cow Health by Dr. Charlie Gardner
One of the most crucial aspects of dairy herd management is fresh cow health. Cows that get off to a
good start produce more, need less care and medication, and are much less likely to be culled
prematurely. Yet I find that many dairy producers do not monitor the level of fresh cow problems.
There is a saying that “you can’t manage what you don’t measure.” How about the measurements in
your herd? Do you know how many of your fresh cows suffer from milk fever, ketosis, retained placenta,
metritis, or mastitis? It is quite easy to track these numbers, with or without a computer. Read the full column.

Vaccinations
Vaccinations Require Attention to Detail by Dr. Charlie Gardner
“I don’t understand how this happened. I vaccinated the entire herd last fall. How can I have all these
cows sick with Bovine Virus Diarrhea. I know that was included in the vaccine.” I can vividly recall
hearing this from a producer whose dairy herd had been devastated by a disease outbreak.
Unfortunately, she had not carefully read the instructions that came with the vaccine. It was a killed
virus product, which means animals needed a second dose a few weeks after the first one to be
protected. Click here to read the full column.

Nutrition and Digestion
Get the Fiber Into the Ration by Dr. Charlie Gardner
“I don’t get it. For years I’ve been told to make better forages, and now I am told to put straw in the
ration. That makes no sense!” I got this comment from a dairy farmer many years ago. I could
understand his frustration, but I also knew why his nutritionist was suggesting the straw. Sometimes we
make our forages “too good,” and we end up short on effective fiber. A small amount of straw can
provide the fix. Click here to read the full column.

Check Out the Manure: It’s a Report Card on Digestion by Dr. Charlie Gardner
In ruminants, digestion of feed occurs primarily in the rumen, with some additional digestion proceeding
in the abomasum, small intestine and large intestine. Manure consists primarily of feed particles that
have resisted degradation throughout the entire digestive tract, and which has been expelled back into
the environment. Examination of manure can provide evidence of how effective the digestive process
has been, and may provide clues of opportunities to improve digestion. With dairy cows, this can lead
to increased efficiency of converting feed into milk, raising total milk production and improving profit. Click here to read the full column.

Housing Decisions
A Three-Prong Formula for Success: Clean, Dry and Comfortable by Dr. Charlie Gardner
The late Doctor Jim Jarret was a mentor to me during my early years in practice. It was from
him that I first heard the phrase, “clean, dry, and comfortable” to describe how every animal on
a dairy farm should be treated. There are three important reasons for dairy producers to make
this happen on their farms. Click here to read the full column.

Be Careful with Overcrowding by Dr. Charlie Gardner
One of the dilemmas that many dairy managers must consider is how many animals
can be put into a given facility. Many operations have found that expansion can be done
by overcrowding their lactating barns until new facilities can be built. That way, they
have animals available to begin filling the new building. What is the problem with this
plan? Read the full column.
