When to Calve

To all there is an appointed time, even a time for every purpose under the heavens: a time to be born, and a time to die; a time to plant, and a time to pull up what is planted; a time to kill, and a time to heal; a time to tear down, and a time to build up; a time to weep, and a time to laugh; a time to mourn, and a time to dance; a time to throw away stones, and a time to gather stones; a time to embrace, and a time to refrain from embracing; a time to seek, and a time to let wander away; a time to keep, and a time to throw away; a time to tear, and a time to sew together; a time to keep silence, and a time to speak; a time to love, and a time to hate; a time of war, and a time of peace. Ecclesiastes 3:1-8 (Hebraic Roots Bible)

For the past several years, my cows have been bred to calve 15 April to 30 May. Though that is earlier than i prefer, it was a decision i made some 8 years ago because i was having up to 30% death loss in baby calves getting scours. Scours so bad that sometimes the calves would die before they even passed that first scouring poop! That was calving 15 May to 30 June. So after a great deal of research into the possibilities, i made the decision to push it back. And that made all the difference – not one single case of scours since that time.

Now, i did sell those cows which lost their calves, so that is likely a good part in the reason there are no longer any cases of scours, yet it’s not the full explanation. Corriente cows tend to have rich milk, which, combined with the heat caused by grazing toxic fescue and the outside air temperature may cause additional stress on baby calves.

However, today’s weather is a reminder of why April is too early in north central Missouri to start the calving. Although my calving season officially starts 15 April, there have already been 6 calves born – fortunately, the weather has been decent until today and it is pouring down cold rain, muddy conditions, temperature at 46F (wind chill 40F) and a stiff 14 mph NNW winter type wind. Very hard are on young and newborn calves.

So, yesterday, after hearing once again from Jaime Elizondo (others have advised as well and i know better), i plan to wait to turn in the bulls 23 July for 45 days. It is with trepidation that i make this change when, despite crappy April weather these past several years, i’ve not lost any baby calves.

Here is to change once again. On the other end of it, it’s always a problem to wean calves the first week of March when grass is yet so far away and there is bitter weather ahead of them. Calving later will allow me to wait another 2-3 weeks before weaning the following year and the cows will have better weather in which to regain good condition. However, leaving the bulls in a couple more weeks is the only way to avoid me being in ragweed season to remove them. (many of my decisions revolve around ragweed season due to me being incapacitated during that time)

So, what have i decided going forward? To completely avoid ragweed season, I plan to turn out the bulls about August 4 and pull them back out about 45 days later which is September 19. Hope it works!!!

Shabbat Shalom!

Calves born earlier – before the onset of toxic endophyte fescue – thrived! This Longhorn cow had a dandy heifer calf.
Never plan to have cows calving in the winter! This was a purchased cow which the seller assured me they were spring calvers – he lied.

Kick the Hay Habit – Jim Gerrish’s Tips for Getting Started

This week’s Classic by NatGLC is from Jim Gerrish. Jim will be speaking about Grazing Lands Economics at the National Grazing Lands Conference in Reno in December, so we thought you’d like to have an idea of what he might cover. Jim is one of over over 50 producers who will be part of the conference talking about innovative grazing management. We hope you’ll join us! Register before October 16 to get the reduced rate of $395, and bring a friend or spouse with you for just $175 more.

Hay feeding still ranks as one of the top costs of being in the cow-calf business in the U.S. The good news is we do see more and more livestock producers ‘Kicking the Hay Habit’ with each passing year. There is much more to kicking the habit than just deciding one day that you’re not going to feed any more hay. It usually takes several management changes to get there.

Here are what I am seeing as the top five moves for getting out of the hay feeding rut.

1. Have a plan for year-around grazing.

This doesn’t mean just hoping you have some grass left over in the fall to use during winter. It means making a critical evaluation of all of your forage resources and mapping out when they can be used most optimally. Develop a calendar of when your stock are going to have their highest and lowest demands. As an industry we have given a lot of lip service to matching forage and animal resources, but the majority of ranchers still do a pretty poor job of implementing a sound plan.

2. Change your calving season to a less demanding time of year.

It is much easier to graze a dry, pregnant cow through the winter than a lactating mama. For many of today’s moderate to high milk producing beef cows, daily forage demand at peak lactation is 50-80% higher than when she is at dry, pregnant maintenance. Late spring or early summer calving seasons work well in a lot of ranch country once you change your mind about a few things. I’ve met very few ranchers who switched to later calving who ever went back to winter calving.

3. Make sure your cattle match your environment and climatic conditions.

You really want your cattle to survive and thrive on the native resources of your ranch. The more petroleum and iron you put between the sun’s solar energy and your cow’s belly, the less profitable you are likely to be. Cattle should be able to earn their own living. You shouldn’t have to earn it for them. Consider every head of cattle on your place to be a ranch employee. Your primary job as manager is to create a working environment for your employees to do their job.

4. Manage all of your pasture and rangeland more intensively.

CP snow grazing Oct 26This does not mean graze it more intensively, this means manage it more intensively. If you do, you will get more forage production and greater carrying capacity from your land. Simply rationing out what you are already growing is one of the easiest places to pick up more grazing days from every acre. One of the strongest arguments I can make for Management-intensive Grazing (MiG) in the summertime is to create more winter pasture opportunities.

5. Change range use from summer grazing to winter grazing.

In most environments with degraded rangeland, switching to predominantly winter use is a great strategy for improving range condition. Many public lands offices are very willing to work with ranchers on this kind of positive change. We do see some agency offices and employees who drag their feet on making any kind of change, but most are willing to work with you if you have a grazing plan that will help them meet their conservation goals.

IMG_9954You may not need to make all these changes in your operation. It depends on where you are right now and where you want to end up being. While some operations go cold turkey and try to make the entire shift in a single year, it may be easier to make the transition over 3 or 4 years. You will take some learning and adjustments to get comfortable with the new approach. Your livestock will also need to adapt to the new management regime.

Most beef herds in the US and Canada are made up of cows that are too big and have too much milking ability to live within the resource capability of the land base. Winter grazing is a lot easier with the proper type of cow on your place. Making the switch in calving season might be as easy as just holding the bulls out for a couple extra months. Changing cow type to a more moderate framed and lower milk producing animal will take quite a bit longer.

The key point is to have a plan for making the transition with a clear target of where you want to go.

Calving, Lambing, Kidding

Many proclaimed experts, farmers, and ranchers alike are confused about what season it is.  ‘Spring’ calving to many means January, February, and a bit into March.  NEWS FLASH! – that is NOT spring – that is winter calving in no uncertain terms and terribly hard on livestock and people (in the northern hemisphere) caring for them.  Outdoor winter calving, lambing, kidding has been described by bold people as animal abuse!

Now before you think me a ‘Bertha-better-than-you,’ please know that we used to do this very thing!  It is the status quo in ranching circles.  We’ve been calving in sync with nature now for nearly 20 years and life is much better and profitable for all.

Nitpick your own operation and life – identify elephants in the room – stop digging a hole and solve the problem with simple solutions.  The key word here is SIMPLE!

Re-warming methods for cold-stressed calves

Newborn calves that have been exposed to exceedingly cold temperatures may become hypothermic or at least extremely stressed. What’s the quickest method to re-warm them?

Mar 29, 2018

By Donald Stotts

It’s been a winter that no matter where you are, you’d probably like to forget. Some parts of the country are warm and very, very dry. Good for calving, but not a promising start for spring and summer grazing.

Other parts of the country have been cold and wet. And with calving season underway for many, it’s worth reviewing re-warming methods for cold-stress calves, says Glenn Selk, Oklahoma State University Cooperative Extension emeritus animal scientist.

Selk warns that newborn calves that are not found for several hours after birth and have been exposed to exceedingly cold temperatures may become hypothermic or at least extremely stressed. “A review of the scientific data on using a warm water bath to revive cold-stressed newborn calves bears repeating,” he said.

In a Canadian study, animal scientists compared methods of reviving hypothermic or cold-stressed baby calves. Heat production and rectal temperature were measured in 19 newborn calves during hypothermia and recovery when four different means of assistance were provided.

Hypothermia of 86 degrees F rectal temperature was induced by immersion in cold water. Calves were re-warmed in an air environment of 68 degrees to 77 degrees where thermal assistance was provided by added thermal insulation or by supplemental heat from infrared lamps. Other calves were re-warmed by immersion in 100-degree warm water. The normal rectal temperatures before the induction of cold stress were 103 degrees.

During recovery, the baby calves re-warmed with the added insulation and heat lamps had to use up more body heat metabolically than the calves re-warmed in warm water. Total heat production during recovery was nearly twice as great for the calves with added insulation and exposed to the heat lamps than for the calves placed in warm water.

“This type of body heat production leaves calves with less energy to maintain body temperature when returned to a cold environment,” Selk says.

By immersion of hypothermic calves in warm water, the study indicated that normal body temperature was regained most rapidly and with minimal metabolic effort.

“When immersing cold-stressed baby calves, do not forget to support the head above the water to avoid drowning the calf that you are trying to save,” Selk says. “Also make certain that they have been thoroughly dried before being returned to the cold weather and their mothers.”
