Proving Hypotheses, Bovine Version

Hypothesis: Photo quality goes down when responsibilities go up.

After examining my photos from a recent visit from our veterinarian, Dr. Bruce Figger, my hypothesis appears to be proven.

Bruce was there to work a small group of calves and preg-check 25 heifers. (I should probably call him Dr. Bruce or Dr. Figger, but he was in 4-H with my kids. He's been Bruce to me for a long time.)

But I digress. Anyway, since we haven't had a full-time hired man since the end of June, my list of responsibilities during said appointment expanded.
Most of my photos were from the rather unglamorous end of the cow (but not as unglamorous as Bruce's position, I must admit). After I helped Randy get four or five heifers from the pen into the lane toward the working chute, I inserted an awkward 20-pound steel pipe behind them to keep them in position.
Then, after each "young lady" finished her turn at her ob/gyn appointment, I would "urge" the next one in line to take her place. And after they were through the chute, we did it all again with the next group. (It was the country version of weight training to lift that heavy pipe multiple times.)
I think Bruce's other "assistant" would have had a better angle for photos. But Tess lacks opposable thumbs, so that option was out, too. (Even Tess refused to look me in the eye for a photo op. It was not a good photo day.)

I've been called into duty a lot this summer and fall for cattle chores. But after a cursory look through several files, I realized I don't have much photographic evidence to prove it.
It's a little hard to use my right hand for running the throttle on the 4-wheeler and my camera shutter at the same time.
 
And, without an extra person, I didn't figure taking a "time out" for a quick photo op would go over too well.
So most of my photos were taken before or after the actual work.
After we rounded up this group of mamas and babies from Peace Creek and I got them turned south, the camera went back into my pocket so I could "keep the dogies" moving, as they say in cowboy speak. (Not that I'm a cowboy either.)
I've had plenty of morning and evening excursions to the Ninnescah Pasture to help shepherd five pair of perennially escaped cattle back into the confines of the fence. And I've seen some new country as we've chased said cattle out of shelterbelts, through hay fields and back to their summer home. But, again, I've refrained from pulling the camera out during these already-frustrating round-ups. Hard to believe, I know.

I guess you'll just have to take my word for it this time.
Even though the photo quality isn't good, these two photos have to rank among my favorites of the summer/fall.
Many, many thanks to our neighbors, Keith and Hendrik, who penned our five pair of escapees and hauled them to our farmstead corrals while we were in Wichita with our granddaughters. Randy took the renegade cattle to the sale barn at Pratt this week. I had lost count of the number of times we put them back in and fixed fence this summer/fall.
 
I don't believe I've ever been so happy to watch a trailer leave. There's a photo worth framing - no matter the photo quality!

The Birds and the Bees (and Other Sticky Topics)

Randy has a secret to wedded bliss: Instead of expecting me to remember numbers while sorting cows and calves, he prepares a "cheat sheet."

I am notoriously bad at numbers. Give me words any day.
My eyesight is also not the best, even with my ever-present glasses.

But if I have something in black and white that I can hold in my hand, things will go much more smoothly ... for everyone involved. (For the uninitiated, BWF means black white face.)
In a pinch, my hand works, too. (I didn't take the photo of my hand with manure on it. You're welcome.)

But at least my hand wasn't where Randy's was during this particular cattle-working adventure. We needed the list of numbers so that we could sort out four cows that hadn't yet calved and one mama whose baby had died.

Most of our mama cows have already had their calves. So Randy wanted to see if the stragglers were pregnant. After hauling them to the working chute, Randy gloved up with a plastic sleeve and did the exam.
I had to hold the end gate up on the working chute so it didn't inadvertently come down and hit Randy in the head.
All four ended up being pregnant.

We sent them into another pen to await the arrival of their calves. And, in fact, two of them had their calves a couple of days later. The cow whose calf had died was taken to the Pratt sale barn.

For a cow-calf operation, pregnancy is the goal. So the bulls also had a doctor's appointment. This time, Dr. Bruce Figger came to conduct what's euphemistically called a "bull soundness exam (BSE)." In other words, is the bull up for the job that is to come this spring and summer?
 
 "You're going to do what kind of test?" Mr. Bull appeared to be asking.

A BSE has three components:
  • Scrotal circumference is highly correlated with semen output and serving capacity. 
  • A physical exam is performed to simply ensure that a bull is physically up to the challenge of the breeding season. Are his feet and legs structurally correct? Is he free from injury and/or infection?
  • The veterinarian then examines the bull's semen to determine if the sperm cells are normal. After getting a sample, Dr. Figger smeared a sample on a slide and looked through the microscope.
With the first look, he was testing the semen for motility, its "swimming" ability to travel to the cow's egg.
Then he smeared the slide with a dye, which killed the sperm. He could then look at morphology, the shape of the sperm. He was looking for abnormalities in the shape, which could indicate a problem with the ability to breed.

The sperm in the upper left is healthy and correct. The sperm nearer to the light is not healthy. The bulls he tested were all fertile.

After the fertility tests, the bulls were each given vaccinations to keep them healthy during their summer in the pasture. It's similar to giving our children vaccinations for their optimal health. Their vaccinations prevent blackleg and BVD, a respiratory disease in cattle.
He also applied a pour-on de-licer.
The bulls are deemed ready for the job, but it will still be a couple of weeks of  "vacation." Then we'll put them to work for their part in creating the Class of 2020.
I agree with most of the bullet points, though at the County Line, we do "fire" bulls for being obnoxious and destructive - especially if that "insubordination" is directed toward humans.
