It seems we often like to reinvent the wheel. Altering things is not always the best option, especially when Mother Nature is involved. If most cattlemen will look out their window and watch their cows graze, I would venture to say they are viewing a wheel that has been reinvented. This alteration is probably not in the best interests of their pocket book or common sense.
Consider something with me for a moment. Suppose a friend has decided to raise the fruit sevlac. That sounds acceptable. Sevlac is a very marketable product. In the event you are not familiar with sevalc, it is a vine that produces fruit once a year, either in the spring or winter. Of course winter-bearing sevlac needs a bit of pampering to get through the weather. The vines need a bit more fertilizer when asked to produce during the fall and winter. When the fruit is on the vine during the winter, they also require more labor. Once in a while they must be covered to protect the tenderness of the fruit during cold spells. When the sevlac plant is laden with fruit, it requires quite a few nutrients that are not readily available in the fall and winter. In contrast, sevlac produced in the spring requires less water, no fertilizer and virtually no labor is involved in production.
Due to these obvious facts, you assume your businessman friend will raise his sevlac in the spring and summer when his labor and direct costs are remarkably less. You are surprised to learn the opposite. Not only is your friend going to raise sevlac in the chilly months, he is going to build a greenhouse. When you try to reason with him, he only insists that the extra monies he makes from his fall grown selvac will more than offset the costs involved, the greenhouse, the labor and the time away from his family.
Aha! Go and look out your windows again. Unfortunately, most of you are the friend I am speaking about above. I dare to point fingers only because I have raised selvac in the past. Notice that sevlac is the inverted spelling of the word calves.
As with the sevlac vine, the cow's nutritional requirements are much higher 45 days before calving and during lactation. When calving in the late winter months, they require additional feed. Like the selvac vine, when calves are raised in the winter, they require much more pampering. Many times baby calves need to be protected from the weather either by bringing them in to warm up at birth or by having barns.
Like the friend, you and I have been tempted to beat Mother Nature. We have asked our cows to give birth in the middle of a blizzard, and raise a hardy calf. We have expected our bank account to muster excessive, unnecessary hay costs, the cost of barns, and expensive pickups capable of hauling tons of hay in one clean sweep.
At Moore Ranch we have become more amazed each year. We have changed our calving date to late spring, calving in April and May. At first it was hard to look across the fence at our neighbor's cattle and see their much larger calves compared to ours in June. We closed our eyes and trudged on.
The bottom line has been the total economics involved. We have cut our winter hay bill to virtually nothing. Last winter was tough. A neighbor who calves in January and February began feeding his cows in November. His cows were beginning to be heavy with calf in November increasing their demand for nutrients along with the stress the cold weather had on them. Most of our neighbors fed their cows nearly two tons of hay last winter. Our grass was in the same condition, however our cow's nutritional demands were dramatically less. We fed our cows less than 2 square bales of hay per head the entire year.
When we compared the economics of late calving and early calving, observed the condition of our cowherd and the calf crop raised out of each, the decision was simple. We won't be raising any sevlac anymore.
