We are using LimFlex to manage our herd size

Our first LimFlex-sired bull calf arrived last week. It represents the beginning of another herd size management strategy we’re slowly adopting.

“Can we keep it?”

Ironically, that was the first comment our kids said when they saw the fuzzy, black calf.

They don’t understand the dynamics of maintaining herd size yet, but my husband and I do. And we’ve finally accepted that we’re raising too many replacement heifers. Too many heifers leads to having too many cows.

I remember when we first mentioned the problem of having extra cows to our team of advisers. The unanimous response was, “That’s a good problem to have.”

But it’s still a problem.

Especially now that the market for springing heifers and young dairy cows is nearly nonexistent in our area. It doesn’t make sense to continue producing something for which there is no market.

So, part of our solution to this problem is to start making more bull calves (and, thus, fewer heifer calves) through the use of sex-sorted semen from LimFlex sires.

Interestingly, the first cows we mated to LimFlex didn’t settle to the beef-hybrid semen, even though enhanced fertility is supposed to be one of the product’s benefits.

But now that we finally have a calf, our confidence in the product has improved, and we’re creating a plan to use LimFlex more consistently.

Are you using beef-hybrid semen on your dairy farm?

How do you decide when to use it and on which cows?

What other strategies do you use on your farm to keep your herd right-sized?
