Hats Off – 100% Tenet Herd

Hats Off - 100% Tenet Herd

I didn’t know about white cowboy hats. How could I?  I’m from Silicon Valley and not raised to be a farmer. Mr. Faith, Vice President of Mellonics Systems Development, in Mountain View, before there was a Silicon Valley, called me into his corner office, he was upset and I didn’t know why. Evidently, I worked for him. He said, “Isn’t it your job to make sure every file cabinet in this building is filled with pencils and paper?” Of course, I replied. “Well, then go down the end of this hall, through those double Dutch doors, and see that that file cabinet is always full!” I had never been through those big double Dutch doors and certainly didn’t know there was a file cabinet there that needed filling. Mellonics did top secret work, that I did know because it took months before my top secret clearance came through. I was in charge of file cabinets, pencils, paper, graph lined paper, paper tablets, but then five file cabinets were labeled Top Secret. Those cabinets were full of folders, one for each employee that contained their top secret security clearance information. I was to keep these files organized. What did all these people do? I didn’t know. That was Top Secret! So, off I go, down the hall with my roll cart full of my usual supplies, until I reach the end where there are two really big double Dutch doors. As I opened one of the doors, what I didn’t know was that this was going to change the rest of my life.

Years later, Laura Christofk, then President of the Purebred Dexter Cattle Association, asked me to come over to show me what she had designed to be the framework for a new online application that would make PDCA the premier Irish Dexter cattle registry in the United States. I was appointed Director and board member of PDCA in charge of technology.  It was a challenge I was up to do. Thirty years ago, I had opened a door and walked into a massive data center containing an IBM 360 mainframe computer. Seeing it for the very first time turned on a switch in my being that changed my not knowing into needing to know and a lifetime career in the Silicon Valley computer industry. I was always aware that what we were all doing was changing the world. Every day, there was something new. We were learning not to question if it could be done, but rather question how it could be done. This was the core culture of Silicon Valley, although it did not include white cowboy hats.

I made a huge mistake as an Irish Dexter cattle rancher and farmer. When selling some calves to Lainey, she asked me if they could be registered with the American Dexter Cattle Association. Of course they can, I replied. My bull, Gunner, was registered with ADCA, PDCA, and the Legacy Cattle Registry. What could go wrong? As Lainey loaded her new halter trained heifer calves, overwhelmed at how easy it was to put a halter on and simply walk them into the trailer, she thanked me and then asked me to send their ADCA registration certificates. Easy, peezy! I called Joel Dowty, Gunner’s prior owner and board member of the American Dexter Cattle Association (ADCA), who proceeded to explain that the calves’ dams’ sire and grandsire needed to have genetic markers on file with the ADCA What? Well, how hard can this be? My cows were were all registerd with the Purebred Dexter Cattle Association (PDCA), a different registry. I called the prior owner of the dam who still owned the sire and soon had tail hairs to send to the UC Davis Veterinary Genetics Laboratory. Notification of completed tests would be sent to the ADCA. After getting the sire’s tail hairs sent, off I went to find the grandsire. During the phone call to Dr. Wes Patton, owner of Glenn Land Farms and last owner of the grandsire, I was informed that the grandsire fell into a pond and died. Well, no real problem, Dr. Patton was an expert on genetics so I asked for the grandsire’s genetic records or stored tail hairs. None! In disbelief I asked why and Dr. Patten explained this was right before genetic testing was even being done. Well, now it’s time to meet personally with Stephanie, the UC Davis VGL cattle genetic specialist to find out how the grandsire’s genetics could be done

As a PDCA director, I was frequently confronted with something new going on. Robin Pittack kept pestering PDCA about some cattle show in Denver that happened to be the largest, premier cattle show in the United States and they are asking for Irish Dexter owners to bring their dexters to the show for the very first time in its 75 year history. Laura Christolfk, our President, asks when is the show? Robin says it’s in January! There’s five feet of snow in Denver in January. Laura agrees to help sponsor the show and suggests that if neither she nor I transport our Dexters to the show, we should at least show up to man the booth. I drove over to the local Tractor Supply and bought — a white cowboy hat.

My meeting with Stephanie at VGL was challenging. She explained that the only way to get the genetic profile on the grandsire was to locate ten offspring, get their tail hairs, produce the genetic markers for all ten, then and only then could the grandsire’s genetic marker be derived. How can this be done? There were exactly ten living offspring of the grandsire in the pedigree database. It turned out I already had access to seven: the sire, the calf, the dam, and four more of my cows. Every week, I would meet with Stephanie at UC Davis. At first, I asked Stephanie to simply look up the case numbers for the remaining cows and she stated that was not possible. Why? Because the cows have privacy rights! This is nuts, they are cows! Undeterred, she told me that I could give her the case numbers, and then she could look up their genetic markers. This was no different than those top secret files I managed years ago. Then, I would ask three guards to each use their code to unlock the file cabinets and could pull out the needed file folders. Now I needed three Dexter owners to give me their case number codes to give Stephanie to pull up their genetic markers on file. Genetics can answer a lot of questions.

The booth at the National Western Stock Show in Denver was busy. Next to us was a booth of a commercial Angus cattle ranch in Wyoming. All the hands in the booth wore black cowboy hats. My hat was white and they addressed me as Sir! Several weeks before this, Laura Christolfk had discussed with me the critical need to figure out how to tell if a steer would produce beef that would be tender. She knew we had the most flavorful beef. Most of the time Dexter beef would be exceptionally tender. She questioned if there could be a tenderness test. On one of my breaks, I walked over to one of the cow barns to check out what might be happening there. It was completely empty except for a straight cattle chute that was set up right in the middle, with a computer on a table right in front of it. This got my immediate attention. A half dozen technicians were working the equipment, getting it all set up, checking the connections, checking the accessories. I was wearing my white cowboy hat. Every question I asked, they immediately answered, and didn’t question me.  They explained how they were using a sonogram wand attached to the platform computer to measure a bull’s back fat. The amount of back fat marbling displayed on the sonar wand computer as a graft would be used to produce a number from one to ten as a measure of the meat’s tenderness. At that moment, five, fully groomed, beautiful looking  bulls were led into the barn by five ranch hands, all in a row, one after the other. Following right behind was a tall, older gentlemen, holding a pair of calipers. He respectfully nodded to me. This was the owner. As each bull was led threw the chute for its sonar reading, the owner with the calipers got behind, on his knees to measure the bull’s sack, calling out numbers to be entered into the platform computer. This was all meant to impress. A computer generated piece of paper, accompanied with the bull, to be given to the auctioneer, held high as he got a fortune for a beautiful looking, well groomed, fully computer measured bull. The owner wore a white cowboy hat.

In the computer industry, there’s a saying, “Garbage in, Garbage out!” I knew, from real world experience, that none of this computer generated measurements were going to predict how tender the beef was going to be. I raised Irish Dexter cattle and sold beef to a local high-end restaurant, Watershed at the Owl, in Grass Valley, California. Every month we delivered a steer, in quarters, to the restaurant for the chef to hang, butcher, and serve to the local foodies to taste and enjoy. We were a USDA Certified Organic ranch. The steers were born and raised on our ranch. All the beeves were raised exactly the same. They were 100% grass fed and 100% grass finished. Every steer was fed exactly the same. When delivered, I personally inspected every one of them. They all had the same leanness. They all had the same fat marbling. Every steer hung for the same amount of time. Each one had the distinctive, amazing taste that only Irish Dexters can produce. Only, every once in a while, one would not be as tender as the others and we would hear about it. It was a very perplexing problem for which we did not have an answer. Taste is a funny thing, it’s both flavor and tenderness. Laura Christolfk’s question, how to tell if a steer would produce beef that would be tender, continued to be relevant.

The reputation of our farm, the reputation of Irish Dexter cattle, everything hung on the issue of beef tenderness. After lots of research into juiciness, fat, marbling, cattle feed, the grass cattle eat, leanness, it all produced gobs of words and antidotal tales that ultimately didn’t offer a clear answer. Nothing gave us a direction or path forward that could provide us with the assurance that beef delivered to a restaurant or deli would be consistently tender. Suddenly, only a few months ago, up pops TenetBeef.com. They are a new genetics lab in Washington State, started by a genetics specialist from Washington State University who claims to have found the genetic profile within cattle that will identify if the animal’s beef will have a tenderness of 10 on the tenderness scale of 1 to 10. This genetic profile is inheritable. Jeff Resusser of Royal Fare Farms discovered TenetBeef.com. He told Eliena Bodtke of Stay’n Put Farm who published them in the Irish Dexter Cattlemen Tips & Tricks Guide newsletter. This is a game changer for our farm.  It means that by testing our cows and bulls, if they are Certified Tenet (meaning their beef will have a tenderness of 10, the best), their offspring will be Tenet. It isn’t believed that Tenet is currently a common trait. Still, this offered to be a solution to our beef business, giving us hope. We immediately, one-by-one, took blood samples and sent them in for testing. The result was a complete surprise. 70% of our Irish Dexter cows were Certified Tenet. By culling our non-Tenet cows, we would have a chance for consistently tender beef. Now everything depended on testing our bull. That result was also great. He, too, was Certified Tenet. We had a path forward. The non-Tenet cows explained the occasions when our beef was not as tender as we wanted. Culling was done and now we have a 100% Certified Tenet herd. Hats off to TenetBeef.com! Thank you Jeff, Thank you Eliena. Thank you Irish Dexter Cattlemen Tips & Tricks Guide. Now I can visit our restaurants and delis and tip my white hat to the customers.

Tools for Measuring Production

Grass-fed beef producers need to carefully track both production costs and cattle performance to determine whether their operations are truly profitable. With the number of variables between operations, this can be quite a challenge! Rising cattle prices can increase revenue, but higher feed, land, processing, and other input costs can quickly reduce margins. 

The Grass Fed Beef Decision Calculator, linked in the article below is an interactive spreadsheet developed by the Pasture Project. It allows producers to model different types of operations—including cow-calf, stocker, finishing, and direct-market businesses—and see how changes in cattle prices, feed costs, weight gain, processing costs, and selling prices affect profitability. Small changes in costs or animal performance can have a significant impact on profit. Having tools to measure production and profit are a huge asset when making overall management decisions for our cattle operation.

How your beef hangs matters

Did you know the way beef is hung during processing can influence eating quality?

Bass Strait Beef uses a Natural State Hanging Method, allowing the carcase to hang like it would stand in the paddock.

This process helps gently stretch the muscles to contribute to improved tenderness in premium cuts like rump and porterhouse. Just one of the many ways we do things differently to deliver you the best beef! 🥩

DEXTER CATTLE – JOY, LAUGHTER, AND HEARTBREAK – SWEET CAROLINE (Part 3)

I needed help and was unafraid to admit it. I was at home and 6 hours away from Sweet Caroline. Taking the animal shelter’s advice, I called “Eye In The Sky Thermal Drone Pet Rescue”.

Philip answered on the second ring. I explained the situation, and the first words out of his mouth were, “I can go tonight.” I lost it. Fear, anxiety, exhaustion hit me all at once. I couldn’t speak for a good 30 seconds. Philip indicated that this is what he does. He asked that I send him a google pin with Sweet Caroline’s last location. He will contact the Sheriff’s department to let them know that a drone will be in the sky. I was flabbergasted but had hope.

I asked Philip is he thought he would find her. He responded, “I am 100% sure I will find her.”

“How can you be so confident?” I asked.

“It is a black cow! I am used to looking for much smaller animals. She will standout.” He was right.

That night, at approximately 8:30 PM, I received a text. I received a photo of Sweet Caroline standing in a corn field. I couldn’t believe it. I called Philip. He said he found her near the woods where she was last seen. She looked healthy and was eating. I couldn’t have been happier. I made plans to meet Philip the next day in Iowa in hopes of bringing Sweet Caroline home.

The plan was to meet with Philip, fly the drone, see Sweet Caroline and walk her to the trailer and then bring her home. That was the plan. Sweet Caroline had other ideas.

Truck and trailer in tow I was Iowa bound. Through my ever growing list of Iowa contacts, I learned the name of the farmer who’s pasture abutted the woods in which we believed Sweet Caroline had taken residence. I gave him a call while in route. He indicated that he did indeed own the pasture and confirmed that there were several head of cattle in it. The pasture was large, had several acres of woods and water. The farmer told me that there was a spring in the woods where Sweet Caroline was at so she had water. He was going to walk his pasture to see if he could see Sweet Caroline.

About 4 hours in to my trip, the farmer called to advise that he did indeed see Sweet Caroline. She literally walked right up to him! She was next to a fence that separated the 2 properties. She was about 10 yards away from a little gate. The farmer and his son tried to get her to go into the gate on this land, but Sweet Caroline was reluctant and wouldn’t go in. They were able to pet her. Not great news, but not the worst news either.

I met with Philip. Philip was going to put the drone up, and once Sweet Caroline was found, I was going to try to get her into the pasture with the other cattle. There were 2 gates. The little one the farmer mentioned and a main gate located along a road over a mile away.

The drone was up. Amazing things these drones. Flying over head and giving crystal clear images of the things below. Growing dark, Sweet Caroline emerged from the woods and went into the corn field. We were located about 1/2 a mile away and I began the walk towards her.

Sweet Caroline, was… well…Sweet Caroline. I walked towards her with a bucket of grain and she walked right up to me. She allowed me to pet her and I allowed her some grain. She looked healthy and good. I had brought a halter.

I have had more people ask why didn’t I just halter her? Piece of cake! First off, she had never had a halter on in her young life. Second off, she wasn’t about to start with a halter in that corn field in Iowa either. With that not going to work, I went with plan B.

We were about 300 yards to the small gate. The challenge with that was the small gate was located on a rather steep incline. To get to that gate, we had to walk through very thick brush and thickets. The fence was barbed wire. Sweet Caroline has never been around barbed wire. There was a large tree stump 3 feet in front of the gate. I walked between the stump and the barb wire fence. The other side of the stump was very thick briars and impassable. I immediately figured out the problem.

Sweet Caroline stopped at the stump. She would not go by the barbed wire. We were 3 feet away from the open gate. She eventually walked back to the corn field. I called her. She came back and stopped by the stump. And walked back to the corn field. We repeated that same sequence 3 times. She was wanting to follow. She wanted with the other cattle. She would not go past that stump.

I walked back to Philip. It was dark. I sent a text message to my Dexter cattle mentor and explained the situation. Through her contacts and Facebook followers, she was able to find someone in Illinois, close to Iowa, who might be able to help. She sent me the information.

I called. They would come the next day, Sunday, after church. Time to bring in the cowboys.

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.

Pest control on the Homestead

Rodent and pest control on the homestead can be a challenge. At our farm we use a multi pronged approach.
We use peppermint oil, glue boards, mouse traps, barn cats, muscovy ducks, chickens, guardian dogs and recently birth control. I have even seen folks use rat terrier dogs. What ever works for you, but it may take a multiple methods to get the job done.
We have found glue boards, I know some find them inhumane, but when strategically place can be an effective tool. We do catch the odd thing that we do not want to catch, but we’re glad they were there even if the capture was unintentional…like this one.

Screenshot

We also use a variety of mouse traps baited with things, but placement again is important so as not to catch the barn cats, who are also a useful tool.

In the pastures the muscovy ducks have been know to be a deterrent for snakes, flies and some say fire ants. Chickens are especially useful when they find a nest of mice or rats. They definitely enjoy their meat.

For the larger pests, the guardian dogs help control the unwanted dogs not from the farm, foxes, rabbits, weasels, mink, air strikes from hawks.

Our last edition has been rodent birth control.  Yes rodent birth control.  The jury is still out on this one…but looks like they are ingesting it… hopefully this will reduce their ability to reproduce and once the adults are caught, we will be able eliminate them. The population is definitely under control.

Finishing Beef on Grass

Grass finishing isn’t as easy as sticking some steers out on grass until they’re fat and ready for processing. For really good flavor and tenderness you need a steady rate of gain. For a steady rate of gain you need quality forage – especially leading to finishing. Every beef farmer who finishes on grass is a grass farmer first. Need some tips on finishing your Dexter on grass?

Dexter Cattle: Mini Cows Are Perfect For Preppers and Small Homesteads

There is no better way to ensure the survival of the family in case of a SHTF scenario and to create a sustainable homestead than to grow and raise your own groceries. There are a plethora of traditional farm animals which can help keep the family well-fed year around or during a long-term disaster, but when both space and budget are limited, one stands out above many of the rest – Dexter cattle.

Marketing and Selling Pastured Pork – Dexters Too !

The time, energy and money you invest in this can give you access to the entire U.S. market. 

Raising pigs on pasture is wonderfully rewarding work, but it will not lead to a viable farm enterprise unless we take the time to develop our marketing program for effectively selling pastured pork. In this article I share some key points and tips I have gleaned in five years of pork production.

The importance of the Dexter Head

Did you know the look of a Dexter’s head was important to breeders and that there was what was considered a “Dexter Head”?

“Harley Penelope is good to carry in one’s eye as a type of a good Dexter cow. She has the quality and character, a sweet small Dexter head and carries her horns well.”

“I lost my heart to Red Rose, a very beautiful cow, she has the Dexter head to perfection”

Did you know that Dexters were known to give a good milk yield for their size and excelled on lower quality pasture?

“Naturally in these times, when the economy of feeding stock is of importance, the hardiness of a Dexter, the large milk given by them on a small quantity of food, and their ability to thrive on poor pastures make them particularly attractive”

Did you know that breeders put a lot of emphasis of breeding to “pedigree and type” not just pedigree or type alone? That people wanted to keep their diets similar so that they could retain their original attributes including size and hardiness.

“It must be born in mind that these cows are not fed on cake: no doubt on higher feeding these records should be raised to 1500lb or 2,000 lb more than those given above, but Lady Kathleen Morant told me: I do not feed with cake ect., I try to keep them as much as possible on the same lines as the Irish peasant would do because I feel that is the best way of keeping them true to type and from getting them large and coarse.”

All these thoughts can be found in this newspaper clipping from 1917, in reference to Kathleen Morant’s Dexter herd along with pictures that describe even more than the words written in black and white can relate.

Getting And Keeping Your Dexters In Optimal Condition.

Minerals are very important!

We’ve shared several articles on the importance of minerals for your Dexters.

We are discussing it again, as it’s a very important topic for the health of your herd. We cannot express loudly enough how important minerals are for your Dexters. Loose minerals are better than blocks, as they can consume much more in loose form, than they can by licking a block. Minerals are made by several different manufacturers. As with anything, you get what you pay for. We esp. like the VitaFerm brand. Many companies offer minerals that target different seasons or issues, i.e. supporting the reproductive system during breeding, heat stress in the summer, selenium, high mag, and others. Consult with your vet, mentor or a feed rep, to determine what could be lacking in your area and thus what you need to support in your herd.
Some people have their hay tested, so that they can determine what they need to make up for in the minerals they supply for their cows. 

Next, let’s talk about Kelp. We started using Kelp this year, for the first time. Thorvin Kelp, is an organic, natural supplement that is packed full of bioavailable minerals and vitamins. It can also be fed to other animals on your farm. The benefits of feeding Kelp to your herd are many. Some of those are improving breed back time, helping with weight gain, preventing foot rot & pink eye. It basically boosts the animal’s immune system. In turn, this helps lower your vet bills and helps keep your livestock healthier. Kelp can be fed free choice, alongside your loose mineral or it can be blended into a feed ration. Talk with your vet or feed rep, with any questions you may have for feeding Kelp to your herd. 
Apple Cider Vinegar or ACV, is another tool that many use to help build up their animals’ immune systems. We prefer the raw ACV, with “the mother” in it. Some say it helps improve cattle health and feed utilization. Others say it also helps prevent and eliminate parasites and resist disease. It’s also been said to reduce horn flies, by making their skin more acidic. It’s going to depend on the size of your water troughs, on how much to add. One recommendation I found, is to mix in 1-2 cups of ACV, per 20 gallons of water or ¼-1/2 cups per 5 gallons of water. Sick or stressed animals can get more, double or triple the amount of ACV, however I would check with my vet, before increasing it too much. 

Worming: There are several different types of wormers available, that target different types of worms and parasites. They come in pour ons, oral, injection and block or pellet forms. If you have pregnant or lactating cows, make sure the one you chose is safe to use on them. Ask your vet or a mentor. Some breeders have a yearly worming schedule.If you have a poorly looking animal that is thin & has a dull looking coat, or it might have diarrhea or blood in their feces, the first thing you may want to do is to gather a fecal sample into a clean container and take it to your vet for testing. This isn’t costly and it will tell them/you the correct treatment to use. The problem can range from the animal needing worming, to possibly having coccidia or another disease that needs treated. 

A lot of our Country is experiencing high temperatures right now. Usually, any added stress to cattle, can lower their immunity to some things. Higher temperatures can be stressful on animals. If possible, consider moving or working your cattle, during cooler days. Weaning in the hot summer months can be especially stressful for calves. Consider waiting to wean, until cooler months. Make sure they have ample shade to get to, and keep fresh, clean water available, throughout the day. 

Veterinarian: YES! You need to establish a veterinary relationship early in your Dexter journey. They are your first go to in an Emergency and for advice. They need to visit your herd and get to know them. This will benefit you & your herd, in the future. Oftentimes, once they get to know you and the herd, you can obtain advice via a phone call and pick up meds, etc. at their office. Like it or not, there will be an occasion where you need an emergent visit. Your investment in your cattle, is worth calling a vet out in an emergency. Lots of breeders, can give advice from experience, but nothing replaces the professional assessment and treatment of a veterinarian who is familiar with your herd. 
We hope the ideas above, give you something to ponder, research and consider doing to benefit the health of your herd.
