Our thinking needs to move to the bulls in the herd because it is the time to start worrying. A bull that is not reproductively sound today more than likely will not be settling cows in June.
The reproductive process in a bull is not something that can be turned on and off. In reality, a bull’s reproductive process never should turn off. If it does, to get it to turn on again is a major, time-consuming process. One could liken the problem to an engine that has the wrong fuel in it during the dead of winter and is stalled on a frozen highway 300 miles from the nearest service station.
As an optimist, one would think that one will get the engine going again, even if it takes until the spring thaw. Any immediacy in getting the engine started probably will cost a lot of money and still take time, so don’t use the wrong fuel and save yourself a lot of stress and work.
Likewise, now is the time to check the bulls to avoid any crises management issues before the weather is nice and the bulls are loaded on the trailer to service a friendly pasture of cows. The cows often are the focus of attention because they have those nice-looking calves walking alongside and are the primary feeding group.
Only after all the cows and calves are fed do we wonder if the bulls have been fed. When one looks at how much bulls cost these days, they should get the same treatment as cows. How often does one drive by a producer’s lot to look at the cows only to notice that the bulls are eating on an old bale of hay in the bull pen? There aren’t that many bulls, so they end up nibbling on the outside of the bale, which eventually turns old.
This is not a good plan; it may lead to procrastination and missing an opportunity for the early diagnosis of a problem. Why early diagnosis? A bull has a very complex process called spermatogenesis. This process occurs in the testis and starts when a cell decides to become a sperm cell. From the onset, the bull requires at least 54 days to produce a viable sperm cell and another seven to 10 days for the sperm cell to arrive at the launch pad. That’s more than two months that is needed for a bull to initiate the ability to settle a cow.
To further complicate matters, we know one sperm cell is not nearly enough. In reality, the bull needs to produce billions of sperm cells in preparation for a day’s breeding. Obviously, awareness and expectation of bull fertility needs to be placed at the top of the managerial list today.
