Designing a Wind Break

Dexter cattle are hardy, needing very little to thrive. However, if they are to be outdoors all season long they should have a shelter or windbreak. A windbreak in the form of trees and shrubs provides valuable shelter, shade, and even a snack, to a cattle herd. Read more below on the basics of designing, planting and caring for a wind break.

DEXTER CATTLE – JOY, LAUGHTER, AND HEARTBREAK – PART 5

The cattle were enjoyable. Each with their own personality. That seems trite, and I don’t mean it to be, but they are all different. The cattle gathered around the bale ring eating hay was a sight to behold and one that I did not take lightly.

Willow, my beloved heifer, didn’t take too long to climb into the bale ring. Not just once. Not twice. Every single day. There is always one. As a new cattle owner, I was surprised, and somewhat revolted. The cows would crap in their hay. The hay that they are eating, they literally crap in it.

“Honey, what’s for dinner?”

“Steak and baked potato.”

“Mind if I take a deuce on it?” At least I asked. The cattle don’t.

Cattle are different. At first, I would climb into the bale ring everyday to remove the manure as Willow had no manners. The cattle continue to eat it, so I learned to live with it. I was picking the manure out of the hay that the cattle pulled out of the ring and then put the hay back in the ring. A bale of hay is expensive and I was trying to conserve.

The cattle had free access to the unused stables. They took advantage and I was so proud of the fact that the cattle could come in out of the weather or wind at any time. I had plenty of straw and also put hay out. And guess what the cows did? You guessed it. They crapped everywhere. The great news is based on what I was seeing they were taking healthy ones. Some consolation when you are picking it up daily. I didn’t mind.

And here is what I didn’t know but wished I did. Every single cow owner will tell you to have a manure plan. Every single cattle owner starting out who doesn’t have a plan will be sorry if they don’t.

Every morning I would pick up the manure in the stables, put in a bucket, and then take it to a manure bin. Perfect plan right? At the time, it worked. It was a lot of work because every morning I felt as if the number of bucket loads were increasing exponentially. No worries because look at all the fertilizer I was going to have.

Fall and then winter. The cattle were eating, crapping, and seemed genuinely happy. I would not miss a day of petting each one and talking to them. Jubilee was growing by the day and every day I would take a guess as to when the baby was coming. Did the calf drop? Is she puffy on her backside? Have her pins dropped? With the way she is carrying it, it is going to be a heifer. Looking back on it, I had no idea as to what I was looking at but it was so fun to speculate.

A call from my fence guy. I hadn’t purchased a fence yet, but I had a guy. He will start building the fence to the pasture adjoining the horse turnout in the beginning of spring. I had plenty of hay and true to their breed the Dexters were not tearing up the turnout area.

My wife. “Does the hay ring look to be sitting up a lot higher?”

“Optical illusion. All hay. They will eat it.”

Of course it wasn’t. It was an issue that will be dealt with early spring once I move the cattle to the adjoining pasture. It will all work out. Once the fence is secure, I will move the cattle on the 3 acres and keep them there all summer. They will have plenty of grass.

Strike one.

A little bit about the author. I own and operate a small farm called “Our Yellowstone LLC” in Illinois. I couldn’t do it alone, but will keep my wife’s name out of it to protect her innocence.

Buyer Must Haves

So you’ve done your research on the Dexter breed and are ready to start looking for your own Dexter’s. Below is a list of paperwork you will want to make sure you get or ask for. I’ve also included some questions you would want to know. Find a mentor & a vet. Two of the first things I would recommend, if you don’t already have those.

  • Sales contract
  • A list of vaccines, wormers, or any treatment they may have had.
  • What do they feed? Grain, pellets, what type of hay.
  • A copy of the registration certificate.
  • If moving the animals across state lines you will want/need a health certificate from a vet and results of any testing required by that state.
  • Question: If buying a cow or heifer, has she been with a bull & if so when is her expected due date. If the heifer is young and has been in with a bull she could have gotten bred. A lutalyse shot can be given by a vet or obtained to give her to avoid a too early pregnancy, which could threaten the life of the calf and cow. Dexters can be fertile at a young age.
  • Will you or the seller transfer the ownership?
  • Ask for copies of their testing from UC Davis or TAMU or at the very least get their case numbers. You will need this info to test your future calves.
  • You will want to get established with a vet, if you have not already done so. You will need one eventually and if they are familiar with your herd, they will be more accessible in the future.

Why size maters. Dexters make sooo much sense! Article written by Todd Hightower

 

The Cow Size Lie Nobody Wants to Talk About

For years, the cattle industry pushed one idea:

Bigger cows. More frame. More pounds.

And on paper, it made sense.

But out in the real world—where feed costs, drought, reproduction, and margins determine whether you stay in business—a different reality has been showing up.

Bigger Cows Eat More. That’s Not an Opinion.

A cow will consume roughly 2–2.5% of her body weight every day.

A 1,200 lb cow will eat around 24–30 pounds per day.
A 1,600 lb cow will eat around 32–40 pounds per day.

That’s 8–10 additional pounds per day.

Over the course of a year, that’s roughly 3,000 pounds more feed per cow, depending on conditions.

Across 100 cows, that’s over 300,000 additional pounds of forage, hay, or purchased feed.

It doesn’t matter if it’s grass, hay, cubes, or silage.

Bigger cows cost more to maintain. Every single day.

What That Actually Costs

That extra 3,000 pounds of feed isn’t just a number.

At current prices, that’s roughly $180–$225 more per cow per year in a hay-based system—and significantly more if you’re feeding supplement.

Across 100 cows, that’s $18,000–$22,000+ in additional cost just to maintain larger cows.

Before you ever sell a single calf.

But Feed Isn’t the Real Problem

Reproduction is.

The most valuable cow in any system is the one that breeds back on time and raises a calf every year.

The 90-Day Breeding Window Tells the Truth

In real-world conditions—whether you are grazing pasture or feeding hay and supplement—cows that maintain body condition breed back more consistently.

Field data and university research show that under limited or variable nutrition:

Moderate-sized cows often achieve 80–95% conception rates within a 90-day breeding season,
while larger-framed cows under the same conditions often fall closer to 65–85%.

Within the first 45 days, it is common to see:

55–70% of moderate cows bred early,
compared to 40–60% in larger cows when body condition is harder to maintain.

That spread may not look big on paper.

But across a herd, it is the difference between:

Cows that calve early, stay on schedule, and remain productive…

And cows that fall behind, slip later every year, or come up open.

That matters more than most people realize.

Run the Numbers

Out of 100 cows:

If 90 breed back, you have 90 calves.
If 75 breed back, you have 75 calves.

That’s 15 open cows.

In today’s market, good 500–600 lb calves are often bringing roughly $2,300–$2,900,
and heavier 600–700 lb calves can push $3,100 or more depending on quality and market conditions.

That’s $34,500–$46,500 in lost revenue from calves that were never born.

But that’s only part of the story.

What an Open Cow Really Costs

An open cow doesn’t just cost you the calf you didn’t get.

She still eats. She still requires care. She still takes up resources all year long.

In a typical cow-calf operation:

Feed alone will often run $600–$900 per cow per year, depending on forage, hay, and supplementation.

Add mineral, health costs, labor, and overhead, and that number climbs to roughly $700–$1,100 per cow annually.

Now put it together:

You lost a calf worth $2,300–$3,100.
And you still spent $700–$1,100 to keep that cow.

That means one open cow is not just a missed opportunity.

It is realistically costing you:

$3,000–$4,200 per head.

And most operations don’t stop to calculate it that way.

Timing Is Everything

Cows that breed early in the cycle calve earlier.

Earlier calves are typically 30–50 pounds heavier at weaning, more uniform, and more marketable.

Late-bred cows fall behind quickly and are often the first ones culled.

What Happens After Calving

Larger cows have higher maintenance requirements.

When conditions are less than ideal, they:

Lose body condition faster
Take longer to resume cycling
Struggle more to breed back on time

Reproduction is the first system to shut down when nutrition is short.

Meanwhile, the Cow That Fits the System

The cow that matches her environment:

Holds her condition
Cycles sooner
Breeds back within the window
Raises a calf every year
Does it on fewer resources
Stays productive longer

This Isn’t About Grass-Fed vs Grain-Fed

A bigger cow can work—if you are willing to feed her enough.

But every extra pound she carries comes with a cost.

And if she doesn’t turn that into:

A live calf
A timely rebreeding
And pounds that pay

Then size is not an advantage.

It is an expense.

Efficiency Is What Pays

Profit is not just measured in pounds per cow.

It is measured in:

Pounds per acre
Pounds per dollar invested
And cows that stay bred year after year

The Truth Most Operations Learn the Hard Way

A larger cow has to wean significantly more pounds just to offset her higher maintenance cost.

Most do not when you factor in real-world conditions.

So Here’s the Real Question

Are you building a herd that looks impressive…

Or one that fits your resources, stays bred, and pays you back every year?

Because when you break it all the way down, one open cow is not just a problem in your herd.

It is a $3,000–$4,200 mistake.

And most people don’t realize how many of those cows they’re carrying until the numbers force them to.

If this made you think about your own herd, share it with someone else who needs to see it.
And follow along—because this is just one of the cow lies most people never question.

Dexter Milk records

Dexter Cattle Milk Yields Officially Recorded

May be an image of textMilk Yields Record taken from a Dexter Cattle Society Booklet

No date was given in this pamphlet but if we consider the Dexters that are pictured we can get a close idea of the date. The top Dexter is Atlantic Alision, she was born Jun 12, 1956. A very beautiful Dexter, but her milk yield was not recorded in the data. The second Dexter looks to be either Atlantic Sprat or his son Atlantic Alistair, I lean towards the latter due to the angle of the legs. You can see some pedigree information on Atlantic Alistair here Legacy | World Dexter Information and it will show you a picture that looks very similar. He was born Jun 9, 1957. The Atlantic Herd was owned by Mrs. W. R. N. Tanner of Hock End Checkendon. Spratt was first in his class and went on to win the Silver Challenge Sheild. Atlantic Alision likewise was a prize winner. Mrs. Tanner had many prize winning Dexters and had a memorable herd of Dexter cattle. Both examples are great pictures to represent Dexter cattle.

Butterfat Content in Dexter cattle

     It is interesting to note that many of these cows had higher butterfat contents. Much higher than a Holstien and some producing as much as some Jersey cattle. The Dexter milk separates cream out slower than a Jersey and some of the butterfat remains in the milk retaining richness to the milk even after skimming the thick cream off the top. These records are a testament to those high butterfat amounts. In order to have a proper milk tests all cows should stay in milk for the same duration of time and ideally be fed a very similar diet. It is very rare today that people will keep their cows in milk for ten months. I however can attest to milking Dexters for 10 months during many lactations and can say there are still Dexters today that will hold a lactation well.

The Dwarf Dexter in History

      The final consideration I must only discuss for those who may be new to Dexters, so this article does not confuse someone into thinking that Dexters must have a genetic problem that causes them to lose offspring. Some Dexter cattle carry a genetic trait that when two carriers are bred together can be lethal. At one time it was common to breed towards what was considered a Dwarf type. Dwarf being exactly as it sounds, having short and broad features. This trait was widely favored by Dexter breeders and at one time selected for, even eliminating Dexters that were not of the Dwarf type (Chondrodysplasia negative) or so called “long legged”. Of course, during this time there was no test for Chondrodysplasia, so not every Dexter that was selected for that had short legs was Chondrodysplasia positive, but many would have been. Very early on observant breeders recognized that there were sometimes bulldog calves that were being produced from the mating of one dwarf type to another dwarf type, while at times other short and broad looking Dexters when mated together were not producing bulldog calves. With “selective breeding” some people have sought to retain and select shorter and still broad looking Dexters without having bulldog calves. These mid-legged Dexters as some people called them were shorter than the long-legged Dexters but were Chondrodysplasia negative.  The long-legged type (Chondrodysplasia negative) some people called the Kerry type. The mid-legged Dexters though they were shorter and fit the breed standard better than the long-legged Dexters still look a little different than Chondrodysplasia positive Dexters. Chondrodysplasia positive Dexters have a look to them that is unique, and there are still people to this day that like them and choose to breed them to retain their unique traits. The two Dexters photographed in my opinion were most likely Chondrodysplasia positive but of course without testing we will never know as there are many short Dexters that have short and broad features that do not have Chondrodysplasia.

Breeding Chondrodysplasia positive Dexters is now simpler than ever because a genetic test was created that identified the gene and now breeders can test to know if their Dexter is Chondrodysplasia positive or negative. With this knowledge comes the ability to breed without the negative outcome of a risk of a bulldog calf. If you only breed a carrier to a non-carrier, you will never end up with a bulldog calf, but instead you have a chance of getting either a Chondrodysplasia positive or negative Dexter from the mating. So, breeders who still like the Chondrodysplasia type can have the chance of obtaining it through wise breeding choices with never having a risk of a bulldog.  For anyone who may be reading this who does not know the Chondrodysplasia status of their Dexters you can find the test here. Simple to test and fairly inexpensive but will save you a lot of loss because knowledge is power.  Bulldog Dwarfism (Chondrodysplasia) in Dexters | Veterinary Genetics Laboratory

The other benefit of testing is that if you do not want to breed Chondrodysplasia carriers, you can likewise use testing to select for Dexters that do not carry Chondrodysplasia while still maintaining the breed standard. Today with testing being so affordable it makes sense to test all Dexters to make informed breeding choices and help buyers evaluate the genetics of each Dexter a breeder has to offer. From great milk yields, butterfat content, excellent beef and the choice of breeding the dwarf type (chondro) or not, Dexter cattle have a variety of genetic traits that can please people with a various goal.

Chondrodysplasia

Article I

Fact or Fiction

This is the first of our articles on chondrodysplasia in Dexters. Also called chondro-carriers, shorties, or dwarfs. these terms refer to the same cattle, and will be interspersed throughout the article. Keep in mind, they all mean cattle who are carriers of the dwarf gene.

Per Miriam Webster chondro means cartilage & dysplasia is an abnormal growth or development.

It’s a personal decision to breed chondro carrier Dexters. Of course, it’s your decision what to breed on your farm. But, let’s sort out some of the facts on these endearing little cattle.

Some long time breeders have told me that they believe the dwarf Dexters played an instrumental part in the formation of the breed, as the non-chondro, longer legged Dexters got registered in with the Kerry cattle. They also believe that there are two body types in the dwarves. That will be discussed in a later article.

Just a few of the traits and statements that those who own and experience the pleasures of owning a dwarf believe.

  • “Chondros are the breed. If we lose them we lose the breed.”
  • “Maximum beef on minimum forage.”
  • Personalities are one of a kind
  • Great mothers
  • High milk production
  • Great for first time cattle owners
  • Of course, breed responsibly. Never breed two carriers together and you will never get a bulldog calf. (If you did, the chance is only 25%, but why risk it?)

Those that I see exaggerating & spreading the hate for chondro carriers are using human graphics from the internet and applying their own labels. I have found no professional veterinary opinion stating they should be eliminated. Of course, none of those who love them would want or allow them to suffer. Many Dexters I know of are living into their teens. How many commercial breeds do you see living that long?

Some dwarfs will get osteoarthritis later in life. So will some non-chondros. A lot depends on the bloodlines, the terrain they live on and the care they receive. This also applies to the longer legged non-chondros. Humans also tend to get osteoarthritis later in life. They also can get forms of dwarfism. We don’t eradicate them. It can be managed, IF it happens.

So, please…. educate yourself on this genetic mutation, before you make a judgement.

The photo with the article is a 9 year old chondro positive cow, with twins she just had.

The following is a scientific explanation from UC Davis. We choose the BD1 test, when we get any calves from our carriers. The BD2 test is for a specific line from a specific bull.
