Heifer Breed-back Improves Sharply With SweetPro Tubs
June 2000 In
1997, commercial cowman, Dennis Mayer of Gackle, ND, was wrestling with
a common problem - getting first calf heifers to re-breed for their
second calf. As he selected for more milk and maternal traits in his
Simmental based-Gelbvieh-cross herd, the number of open first calf heifers
had climbed to between 20% and 25%.
Nearby SweetPro dealer, Duane
Nester of Streeter, ND, recommended extended use of
SweetPro 16-24.
Results were dramatic. The first year Mayer had only 8% opens out of
180 cows in the entire herd and 2% opens the following year. "It's the
only thing we've done different," Mayer noted. "It really made a difference."
Heifers are put on the SweetPro
tubs one month before breeding and they stay on the tubs until Fall.
"They'll typically eat a pound to a pound and a quarter a day, per head,"
said Mayer. He added that it solves a nutrient problem. "These young
cows are having a hard time raising a calf and growing and changing
teeth and still getting enough nutrients strictly from grass. This (SweetPro)
helps - it helps a lot! The cow that milks a lot will raise you a bigger
calf so you have to provide the nutrients for her so she can re-breed."
Mayer also said that the
breed-back improvements have also helped in his overall herd management,
changing culling decisions in an operation where all heifers are home
raised. "We don't buy any, so we've got two years invested in that cow.
They're the future of your herd, so if you start throwing them away
as opens, it's not very good economics and it doesn't improve your herd."
Mayer also added a pragmatic
note about culling when all your cows come in bred, "Now you can pick
out the one that's got the bad feet or the one that chased you over
the fence right after she calved - all those things we as cattle producers
tolerate in the interest in having the numbers around to fill our pastures."
On mature cows, Mayer is
also using SweetPro for improved breeding. As with the heifers, tubs
are put out a month before the bulls go in, but rather than keep tubs
out until Fall, as he does with the heifers, cows are only on the tubs
two months.
