IANS – Extended Lactation in Cows

It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so. ~ Mark Twain

When George Gershwin composed the song It Ain’t Necessarily So, he was onto something. I’d love to have a nickel for everything I was taught or told or just accepted as fact in the course of my life. From food preservation to gardening to animal husbandry to medicine to finance, there have been a lot more ‘not-so’ things than ‘so’ things. A while back I did a post on not needing to waterbath jams and jellies; I got more than 100 comments corroborating my “not-so” position. At which point it occurred to me there are lots of other not-so things out there, and shazaam, I had an ongoing blog topic. Here’s the latest “it ain’t necessarily so” (IANS).

Cows can only be milked for about nine to 10 months on one lactation, then they must be dried up.
An extended lactation is possible for some cows. I milked almost two full years when Maybelle lost a calf and the breeding schedule wouldn’t work out. I feel strongly that I want my cows to produce calves in spring when there’s plenty of good green grass and the weather is warm. It’s also when the deer are dropping their fawns. Cougars are a problem around here, so I’d rather they hunt fawns than my calves. Rather than breed my milk cow and have a calf in the February, which is the norm for beef cows up here in far northern California, I decided I’d rather wait until I could get her back on her usual schedule. She did fine. By the end of the lactation she was only producing about a gallon a day. That was enough for me and no strain on her.

Now, there’s a caveat here. In the case of the milk cow – especially a pure-bred milk cow – they are much more fragile from a health standpoint because it isn’t natural for a cow to continue to produce high amounts of milk for 10 months of the year. Dairy cows are harder to manage than beef cows and an extended milking can be stressful for the cow. Breeding efforts for dairy cows have typically focused on production to the point that a milk cow requires much better nutrition and management than a beef cow to prevent serious health issues. In my case, I only had the one milk cow to manage, so I could keep a really close eye on her health and nutrition-wise. If she had shown any signs of health issues, I would have dried her up immediately.

There are some dairies that are interested only in the milk and have moral qualms about butchering excess calves for veal, so they have stretched the lactation period to as much as four years on a single freshening. They say their cows do just fine on this schedule, although occasionally a cow will have trouble breeding back after such a long lactation.
One disadvantage to this method is that you have to deal with milking a cow in heat every three weeks or so – it can be downright dangerous and at the least is a nuisance. I probably wouldn’t try this with a cow that goes completely nutso when she’s in heat, especially now that I don’t move as fast as I did 20 years ago. But cows are individual, just like people. Some are reasonably mellow even when they’re in heat.

Take a Missouri Approach
Missouri is the “show me” state. The mental attitude of “you’ll have to prove it to me” is a good one. Use your common sense. When your experience or that of people you trust is contrary to accepted scientific wisdom or expert recommendations, odds are very high the scientific wisdom and the experts are out to lunch. Ask the old homicide lawyer’s question, “Cui bono?” Loosely translated as “Who benefits?” what it actually means is “To whose profit?” When big bucks, company survival or professional reputations are on the line, ethics quite often take a back seat. Circus entrepreneur PT Barnum is credited as the person who coined the sucker-born-every-minute rule. In fact, there’s no evidence that he did say it; however, there is some evidence that it was said about Barnum’s tactics, by a banker named David Hannum. Don’t be a sucker and remember: it ain’t necessarily so.

Farmers and Education

It never ceases to amaze me that so many people have a vision of farmers and ranchers as hayseeds who have limited education and can just barely read. That prejudice often extends to all of those who dwell in more rural areas. It’s as though “formal” education and advanced degrees are the prerogative of those who “work clean.” One of the girls who graduated from high school with the eldest granddaughter talked about the
prejudice she ran into along those lines. In her valedictorian commencement speech, she said her advanced mathematics teacher asked why the student would need such knowledge if she was “just going to be a farmer.” Other counselors and teachers expressed surprise that she would have such high grades since she came from a farming background. These folks were not only displaying an unfortunately common prejudice about those involved in agricultural work, they were sadly misinformed. In reality, there are plenty of folks out there in the sticks who are highly educated.

Don’t let the google-eyes fool you; all these 4H kids either went on to college or are headed there.

As of 2017, 69 percent of farmers under 35 years old had college degrees, according to the US Bureau of Labor Statistics. That’s considerably higher than the general population. About one-quarter of all farmers have college degrees – and not necessarily in agriculture. Writer and farmer Wendell Berry holds an MA in English from the University of Kentucky and was a Guggenheim Fellow. The late Contrary Farmer Gene Logsdon completed the work for a PhD, although he never actually got his doctorate. I’m willing to bet, knowing Gene, that he got ticked off at jumping through the required hoops and told the dissertation committee to go take a hike. Elizabeth and Paul Kaiser, of Singing Frogs Farm in Sebastapol, have multiple degrees. The Kaisers’ degrees are in international relations, natural resources management and sustainable development (Paul), and public health and nursing (Elizabeth). John Jeavons (Ecology Action/Biointensive Gardening) has a bachelor’s degree in political science from Yale. Mel Bartholomew (Square Foot Gardening) was trained as an engineer. Elliott Coleman (Four Seasons Farm) has a master’s degree in Spanish literature.
I have a couple of friends in a very small community up the road about 40 miles who have lived in the woods since the 1980s or earlier. They use a Pelton wheel to generate their electricity and implemented a number of other forward-thinking improvements on their homestead well before such things became fashionable. One is an electronics and computer wizard; not sure what his actual degree is but I suspect it’s a master’s or PhD. The other was a nuclear physicist in a former life. However, I know him from his multi-year tenure as the executive director of a small community health center well out in the boonies. He LOVES data-driven decisions and is fond of saying that very few things in this world are rocket science. His favorite tee shirt is one a group of friends got him to celebrate a major birthday milestone. The logo on the front of the shirt says, “It’s not rocket science.” The logo on the back reads: “But I AM a rocket scientist!”
In my own little town – about 400 souls when everybody’s home at night – we have three veterinarians, a dentist, a Doctor of Divinity, several registered nurses, at least six teachers, a physician and a lawyer. My late father was a vascular surgeon and a rancher. I can think of at least 10 local people off the top of my head who hold either bachelor’s or master’s degrees. Some, like the Kaisers, hold more than one advanced degree. You’ll find them building fence, bucking hay, wrangling cows, raising their own food and cutting wood. Apparently they don’t buy into the notion that higher education has no place in the farming world.

Your Brain on GPS

Isn’t GPS wonderful? In the long run, the answer is probably no.
Using GPS regularly makes parts of your brain atrophy.
Not all that long ago I was waxing eloquent (or frothing at the mouth – take your pick) about how technology affects your ability to perform certain tasks. Well, it seems there are some other folks out there who have similar concerns. The hippocampus is a part of the brain that regulates emotions. It is associated with memory (especially long-term memory) and is important for spatial navigation – your ability to move around in your environment.
Neuroscientists have found that using GPS can cause atrophy in the hippocampus. Apparently that’s because you have no need to create and remember your own routes. You have no need to make decisions. You don’t have to pay attention to your surroundings. It’s like the difference between being the driver or the passenger in a vehicle. Ever been some place unfamiliar? Could you find your way back? Odds are, your chances are better if you were the driver.

Driving the four-wheeler is a rite of passage for a ranch kid (the big one has now graduated to the backhoe).

The hippocampus needs experience to function properly. Taxi drivers in London had more volume in that part of the brain because they had memorized the streets and landmarks while driving over them day after day. Other research shows that no matter how old you are, if you use the hippocampus for navigation on a regular basis, you’ll have more volume in that area. Atrophy in that area of the brain, however, has been linked to Alzheimer’s disease and post-traumatic stress disorder (PTSD).
I’m willing to bet that it’s not just GPS. Using any kind of technology on a regular basis is probably affecting our brains in a lot of negative ways. And in kids, whose brains are still developing, those effects are likely to have serious consequences for all of us. Heavy social media use, for example, has been linked to a more than tripled increase in teenage depression. And make no mistake, technology is actually rewiring our kids’ brains as well as our own.

Hands-on with the old stallion; brain, body and emotions engaged.

So what does this have to do with ranching or farming? Practicing navigation – even if it’s just going from the house to the north forty – makes you engage with and become attuned to the natural world. If you are engaged with nature, you notice things like fewer birds and amphibians in your world. You become more sensitive to small changes in the way plants grow. You can glance at a cow and see that it doesn’t feel well. It’s the complete opposite of the way too many people these days spend their time fixated on a tiny screen. When you are not engaged with nature, you don’t even notice how the world is changing.
