2026 Calving Results: South Poll and Angus

August 13, 2026

My education continues! We used an Angus bull and a South Poll bull to breed our Red Angus heifers last year. Both bulls had actual birth weights reported in the 50s, so I was confident we wouldn’t have calving difficulties. South Poll doesn’t have EPDs, but the Black Angus had calving ease and birth weight EPDs in the top 1% of the breed, giving us even more confidence.

Since the Black Angus is homozygous black, I knew I would be able to tell parentage as the black calves would out of Blackie, the Black Angus, and the red calves would be out of Teddy, the South Poll. I planned to weigh all the calves at birth and keep records, figuring this would be a fun real world experiment.

I predicted each bull would sire roughly half the calves and the birth weights would range from 50 to 70 lbs for the Angus and 50 to 80 lbs for the South Poll. I optimistically predicted no calving difficulties. 19 out of 20 heifers calved in April and May.

The first surprise was the number of calves sired by each bull. The South Poll sired 18 out of the 19 calves. The one calf out of the Black Angus was a nice little heifer, 54 lbs, no surprise there. But the South Poll surprised us with larger than expected calves, especially the bull calves.

The top photo shows our first calf out of Teddy, an 80 lb bull calf, born April 7th. I let the heifer work for a while and she had it on her own, but it was a hard delivery. The calf’s face was slightly deformed from dystocia.

The next photo shows Isabel holding an 82 lb bull calf. Beautiful calf, but too big for my liking. And they just kept getting bigger as spring pasture improved. We had four hard pulls with two dead. The calves we pulled were 88 to 95 lbs. Nine bull calves averaged 88 lbs with a range of 80 to 95 lbs.

The last bull calf was born unassisted, but I didn’t get him caught to weigh. He’s in the bottom photo and probably weighed around 80 lbs.

The heifers out of Teddy weren’t too bad, averaging 69 lbs with a range of 62 to 76 lbs. We also had twins out of a heifer, the first time we can ever remember that happening for our farm, with the bull calf weighing 65 lbs and the heifer weighing 50 lbs. I didn’t include them in the averages.

I wrote an article for Stockman Grass Farmer about crossbreeding and potential calving wrecks, but it appears I had to learn the lesson for myself, a lesson I won’t soon forget. I shouldn’t blame crossbreeding, as animal scientists report only around a lb and a half increase in birth weight due to hybrid vigor. But I do think South Poll, being a composite breed, probably passes more variability to its offspring? Otherwise I’m not sure how to explain the large birth weight calves.

We almost never buy females, choosing instead to raise from within our herd, so I know the heritage of our heifers includes some large birth weight calves and trouble calving. But I was counting on some prepotency from Blackie and Teddy to give us small calves with no calving difficulty. I believe both bulls come from honest herds, so I’m not questioning their actual birth weights in the 50s. I’m just surprised I guess, but that’s farming and life. Keeps life interesting.


2026 Herd Bulls

July 2, 2026

We’ve been suffering through a hot and humid few days at the beginning of breeding season. Praying the bulls can handle the heat and still do their job. We’re only running four bulls this year. All of these bulls were developed slowly with little to no grain so I believe their ability to do their job is superior to bulls who were grown fast with a high grain ration.

Bobby, the bull in the top photo we raised from a calf, is out of our black, Red Angus cow. He’s three years old. He’s in an 80 cow herd with Teddy, our South Poll bull in the photo below. Teddy is two.

Look at how slick Teddy is. He carries the “slick” gene which helps him stay cooler. So far, I see Teddy being more active than Bobby. We may get a lot of calves out of Teddy next year.

Above is Blackie, our calving ease sire from Rocky Road Farm Angus with his twenty heifers. He’s two years old.

Below is another bull from Rocky Road Farm Angus, a yearling named Driftless, freshly delivered, waiting to be turned out with his twenty first-calf heifers.


Decision Making

April 27, 2025

I don’t know that “hindsight is 20/20,” but I do think we work hard to understand our life.  The past is neat, because we’ve reduced it to a story.  What often isn’t talked about and largely forgotten after the fact, is the unsettled feeling we have when trying to make a decision in the present.

You look at anyone who’s been doing something for awhile and its easy to think that he or she has it all figured out, but if we’re being honest, I don’t think we ever have it all figured out.  Whatever we’re doing in life, there’s going to be some level of uncertainty.

I think the important thing is to continue to make decisions, implement, observe and evaluate results, then reconfigure and make more decisions.  Try not to beat yourself up about the decisions that didn’t work well.  Did you learn something?

I was faced with making bull buying decisions after we got rid of half our herd bulls last fall.  I knew I had time, we don’t turn our bulls out until the fourth of July, but I also knew I needed to work on this when I had more time during our slower winter season.

We had used four older bulls on our cows and two yearling bulls on our heifers.  After culling, we were left with one older bull and the two yearlings.  So I could add bulls to breed my cows or I could move my yearlings up to breed the cows as two year olds and buy younger bulls for my heifers.  I figured I only needed to purchase two.

I got a line on a couple coming two year old Black Angus bulls from a local breeder friend of mine.  They were priced right and big enough to use on cows.  I drove south of town and took a Ranger ride with Matt and checked them out.

They were good bulls and would make good calves for me.  I planned to use them as a terminal cross, selling all their offspring as feeders.  But I wasn’t 100% sure of their disposition.  

I asked Matt if I could show them to Isabel, that’s one of the benefits of buying bulls close to home, easier to observe, and we went back to the pasture they were in and looked at them again.  Without Matt and the Ranger, their disposition was a little worse, so we decided we would keep looking.  This was October, so we had time to be choosy.  If it had been June, we would have purchased them and probably been happy.

I visited a Red Angus herd in southern Iowa and determined most of his cattle were too related to my own.  I’m still glad I took the time to see his cattle as you always learn something when visiting with other farmers and ranchers.  His bulls were my last best shot for bigger bulls to breed my cows.

I shifted my focus to look for bull calves to breed to my heifers, planning to use last year’s yearling bulls to breed my cows.  I planned a trip to Missouri to visit a couple South Poll herds, but couldn’t make our schedule work.  I watched a couple of Pharo Cattle Company bull sales online.  I was interested in PCC’s Nebraska sale, but again couldn’t make our schedule work to visit the sale in person.  I really didn’t want to buy a bull sight unseen.

But then I got an email from Kit Pharo saying they were waiving the delivery fee for the Red Angus bulls.  I could buy a Red Angus bull online and have it delivered to Monticello Iowa, only an hour and a half from my farm.  This was too good of a deal to pass up.  I marked up my catalog and prepared to bid.  

The day of the sale came and I bid on 26 bulls, but stuck to my budget of $5000.  I guess I’m too cheap, as I didn’t get one.  I was disappointed, but I knew I still had time, so I wasn’t panicking yet.

I visited Matt’s herd again to look at his weaned calves.  Matt pointed out a bull calf whose birthweight was in the 50s and whose EPDs for calving ease and birthweight were in the top 1% of the Angus breed.  Furthermore, the calf and his dam both had a gentle disposition.  Disposition and Calving Ease are my top two traits, so I only needed a day to think about it and pulled the trigger and picked him up so I could grow him slowly.

Now I relaxed, as I had just enough bulls if I didn’t find another one, but I kept looking.  The Missouri South Poll Association had a sale.  I watched it online.  The best cattle in the sale in my opinion came from Sassafras Valley Ranch.  This was one of the farms I wanted to visit in Missouri.  

I contacted Bruce Shanks, the owner of Sassafras Valley Ranch in February and he told me he had a South Poll bull calf which fit my criteria.  I decided to take a flier on a South Poll bull, sight unseen, and met Bruce with my truck and trailer in Southern Iowa, saving me about six hours of driving.  I’m super happy with this bull’s disposition and look forward to witnessing his progeny’s calving ease next spring.

And now we are nearly three weeks into our calving season.  The yearling bulls I used last year did an excellent job breeding the heifers.  Fifteen out of 23 heifers have calved, with four of them looking close.  It looks like four heifers didn’t breed, as I experimented with a shorter 45 day breeding season.  This is perfect for my grass-fed beef needs, so I’m super happy with that decision.

And I’m happy we are moving these bulls to breed cows this year, as their calves have been too large for my liking to breed again to heifers.  I guess I would still call them calving ease though, as we haven’t had to pull any calves.

So we’re all squared away for this coming breeding season and excited to see the results in a year or so, but if you had told me a year ago that I would be breeding my heifers to a Black Angus and a South Poll I would have been surprised.  Farming, just like life, is a journey.

2025’s heifers and calves are pictured in these two photos.


Crossbreeding with 2 New Bulls

February 27, 2025

For the past 25 years we have been using Red Angus bulls exclusively. This year we still have 3 Red Angus bulls for our cows, but will be crossbreeding our heifers with two new bulls. The red bull with two white tags is a South Poll from Sassafras Valley Ranch in Missouri. The Black Angus behind him is from Rocky Road Farms Angus, right here in Darlington.

I’ve never been opposed to crossbreeding, but I needed to find the right bulls. These bulls are excellent for our top two traits, disposition and calving ease. I’m excited to get some hybrid vigor back into our cattle.

I plan to use them together to breed about 30 of our Red Angus heifers. I’ll have to wait until April of 2026 to get calves on the ground, but I plan to get birthweights on all the calves to compare South Poll to Black Angus. It won’t be scientifically significant, but it will be anecdotally interesting. It will be easy to determine parentage as black is a dominant color in cattle and since the Black Angus bull is homozygous black, any black calves will be sired by him. All the red calves will be sired by the South Poll bull.

Check back for results of this experiment in June or July, 2026.


New Herdsire

September 18, 2024

This is the boar I raised and plan to breed to the Landrace sired gilts from the previous post.

I love his dark color, he’s almost black, even though he’s mostly Duroc.


Landrace Swine

July 29, 2024

I’m officially going on record and saying Landrace are more intelligent than the other breeds I’ve worked with. I’ve long suspected it, but this latest group of half Landrace hogs confirms my suspicions.

First example is the way they deal with electric fence. Most hogs, once trained to electric fence, respect it like you respect a beloved mentor. But these trained Landrace hogs respect electric fence like you respect a younger sibling. Definitely some testing of limits and boundary pushing!

Second example is when I moved them to a new pasture. After only a day of exploring, I fed them grain in their new pasture and some of them were stuck in their old pasture. They had to move away from me and go around a corner in order to get to their new pasture. This would’ve been impossible for most of my hogs to figure out, but it took these guys about five seconds to figure it out.

I’m really impressed with this group of half Landrace hogs produced by artificial insemination and plan to keep two or three gilts out of the group. I was so happy to find another Boar stud, North Iowa Boar Stud. I used Swine Genetics International for nearly thirty years, but the last time I called I was informed they had sold all their maternal boars and only had showpig sires.

I was in shock. It’s like hearing Hershey no longer makes chocolate bars. But times change. I guess they no longer have the demand. Thankfully, North, Iowa Boar Stud has a lot of maternal and meat quality boars for me to choose from. I hope they stay in business for a long time.


Swine Genetics: Reminisce

January 26, 2022

UPDATE: Taking orders for delivery every other Saturday to Madison. Next date: March 5th.  Email Matthew with order and/or questions: oakgrovelane@yahoo.com. Thank you!

Blue, red, white, pink.  1st through 4th ribbons at the Lafayette County Fair.   We didn’t have participation ribbons.  Whatever you were showing, the judge told you where you stood.

We showed everything from cattle to crops, but my favorite to show was hogs.  Other than some success in showmanship, that’s where you’re being evaluated rather than the hog, I was stuck getting white and red ribbons with my hogs.

I always had an interest in livestock genetics and subscribed to the breed journals which I read cover to cover every month.  My favorite was “The Hampshire Herdsman” which covered my favorite breed, Hampshire.

Most of the journal consisted of breeder advertisements.  Even at a young age, I understood that much of a breeder’s success was based on perception.

It was interesting to see the different types within a breed and how type changed over time.  I understood that some change was based on the hopes of improvement of the breed.  And I cynically understood some change was based on the need for leaders to change type to stimulate demand for their stock.

One breeder who never wavered in the type of Hampshire he was striving for was C. Elliot Driscoll, of Waldridge Farms.  

I noticed his two page ad in every July issue, (the biggest and best, herdsire issue), of The Hampshire Herdsman.  He always had something to say and didn’t care about offending other breeders.

While it did seem he had a chip on his shoulder, Mr. Driscoll also displayed a sense of humor in his advertisements.  He listed his children and their various occupations, with the boys starting out as “sanitation engineers” and gradually moving up through the ranks to “apprentice breeders”.

I showed Waldridge Farms ad to Dad and asked if we could buy a boar from them in the hopes of improving our hogs.  Dad said sure.

Dad made the 3 hour drive in our Ford ton truck with the stock rack on the back.  Must have been a school day as I didn’t go with on this first trip.  I’m guessing it was around 1985 or 1986.

Dad brought home two boars.  I named them “Wolfman” and “Spock”.  Wolfman was a big, wide-belted boar.  Spock was an off-belt, almost black.  

We had a good base of maternal gilts sired by some good Yorkshire boars we purchased from local Yorkshire breeder, Larry Teasdale.  Wolfman and Spock went to work breeding those gilts.

We saw improvement in our hogs right away.  We went from white and red ribbons to blue, at the county fair.  But the biggest benefit to our farm was economically.  

Perhaps in response to the detrimental effects of the stress gene, I’m not sure, I was too young to know exactly why, breeders selected away from the lean and narrow hogs of the 1970s, and towards short, wide, and ultimately fat hogs in the 1980s.

I remember one Lafayette County Fair carcass show in which the judge kind of chewed out the hog producers as there were hardly any good carcasses and the worst carcass had about two inches of backfat and the loin, (pork chop) was smaller than the largest lamb chop.

Consumers were avoiding fat and starting to demand lean meat.  It was clear that type needed to change once again.

In an effort to promote and pay for lean muscle, pork processors started measuring individual hog carcasses for fat and muscle and paying the producer accordingly.

We were paid a premium for our Waldridge sired hogs.  And, in an effort to help other producers in the area, buying station managers started to promote our hogs to other producers.

Producers started to ask to purchase our Hamp-York gilts for replacement females.  So we obliged, charging $50 over market price.  Demand was good, and this became a nice sideline business.

We alternated Teasdale Yorkshire boars one year, and Waldridge Hampshire boars the next, into the early 1990s.    By this time, breeders had responded to the call for lean hogs and as usual, were taking it too far.

Waldridge hogs were no longer the leanest, meatiest boars available.  I remember discussing this with Mr. Driscoll.  He wasn’t worried, as he knew the type of hog he wanted to raise and wasn’t influenced by prevailing winds of change.

He said something to the effect that a hog with .8 inch backfat and a 6.5 square inch loin was always going to be a good hog.  That really stuck in my mind.  Whenever I’ve been confused about the direction of my hogs, I remind myself of that truth.

By 1994 when I came home from college, it was clear the swine industry was continuing to change.  Teasdale Yorkshires sold out before the market collapsed that year.  Many producers exited the business.  1998 and 1999 were two more brutal market years for the swine industry and many more exited after that.

In college I saw the benefits of artificial insemination and decided to close our herd to new stock, only bringing in new genetics via AI.  August of 1994 was the last time we brought new animals onto the farm.

While many producers had exited the swine industry, there were still enough producers left who needed boars that I started and developed my own business selling boars.  This was a good business for me from 1995 to around 2010.

By then, so many producers had left the industry, I could see the writing on the wall.  I only sell boars to two producers now.

I pivoted once again into selling meat direct to consumers in Madison.  This has been really enjoyable.  As a farmer, we know we are producing food, but I’m one of the lucky ones who actually get to know the consumers enjoying our food.

I guess I’ll end by thanking Waldridge Hampshires, Teasdale Yorkshires, and Swine Genetics International for providing the good swine genetics that help us produce good pork.  Thank you!


2020 Herd Boar: End Zone

January 29, 2020

IMG_0024

Last year’s post, “2019 Herd Boars”, talked about two of my all-time favorite herd boars, Zone and End Zone.  Father and Son, sadly, I decided to sell the Father as he got very big, over 800 lbs, and his son, End Zone, was breeding well.

And then, wouldn’t you know it, when I was down to one boar, End Zone got hurt.  I think he hurt himself in his mud wallow, as the mud had gotten very sticky.  This isn’t a problem confinement pork producers worry about.

I wasn’t sure if he would get better, but I separated him so he could rest and thankfully he did and is back better than ever.  I was able to use artificial insemination to breed one group of sows who will farrow in March.

I kept a white son of Zone and we will see how he develops.  I really like the confirmation of End Zone.  He has a lot of length and is close to perfect on his feet.  He is also easier to work with than his Father.  So I’m hoping I can keep him from getting too big too soon.

2019 Herd Boars

February 12, 2019

DSCF3326

 

The best two herd boars I think I’ve ever had are Father and Son.  Zone, pictured above is out of an AI mating, Waldo Duroc, Red Zone.  I had been having trouble with my boars not having much mating desire, but Zone is excellent.  The only problem is he is also people aggressive, but I think I can continue to work with him if I’m careful.

He is being mated to Chester White sows out of an AI mating, Longevity.  They will farrow this spring and I’ll evaluate them again.  The Chester White gilts definitely had less piglets born and saved than my Landrace gilts in the past.

DSCF3310

End Zone is pictured above.  He is a son of Zone.  He is being mated to Rising Sun Duroc gilts for early summer litters.  The Rising Sun gilts have very friendly personalities, but we’ll see how they do as mothers.

Another photo of Zone.  He has a lot of length.  He is also getting tall as you can see he has to duck to get out of his shelter, pictured below.

Chester White Litter 2.0

November 8, 2018

DSCF3178

November, the last litter of 2018.  Cold as heck outside.  Warmer next to your momma.

This gilt was featured in one of my farm videos last year.  She is one of the piglets in the video.  I made the video because I was excited for new genetics.  This gilt and her siblings, were sired by Chester White semen I purchased from a boar stud in Iowa.

I wanted to try the Chester White breed because it is know for mothering ability and meat quality, two of the traits most important in my swine herd.  Also, Chester White is an American Heritage breed.

I love eating “General Tso’s Chicken” at the Chinese restaurant in town.  And I’m sure “General Tso’s Chicken” is heritage food to someone, but its not my heritage.  Farmers, let’s make our own heritage!

Back to this Chester White experiment.  I kept all five of the gilts from that litter and bred them to my Duroc boar.  They have done well, good mothers.  Interestingly, they don’t have as many piglets born as my Landrace genetics.  They seem to be very similar to my Duroc genetics, as I always select for mothering ability and meat quality when I purchase Duroc semen as well.

What’s nice is that I was able to conduct this experiment in a relatively short amount of time as the generation interval in swine is about a year.  The generation interval is the amount of time it takes for any species to reproduce itself.  In cattle its about two years.

The generation interval is important to geneticists and animal breeders because it adds a time element to any “progress” that can be made in a species.  I put “progress” in quotes because geneticists and animal breeders are people like you and me.  And like you and me, its way easier to make change for change’s sake, than to stop and figure out where exactly you want to go and why, and if its going to be a good when you get there.

Okay, if you’ve made it this far, comment and let me know what you think about “heritage” and “progress”.  And check out my youtube channel if you want to see more of our farm.  Thanks!
