Early calves are worth more: Synchronization can move cows up in the breeding season

On some ranches the bulls are already out, at least with the heifers. For most of the rest breeding season is just around the corner. At a UNL Department of Animal Science – Nebraska Extension Beef Group meeting last week. We got into an interesting discussion calf age after one of the graduate student’s presentations. It doesn’t matter when you calve, calves born in the first 30 days of your calving season are worth more. They are bigger when you sell them. The heifers are more likely to breed early in their first breeding season. Which means they will calve early in the season, which sets them up for a lifetime productivity advantage over their later born herd mates.

The discussion we got into was about synchronization and how even if you just use bulls and don’t AI, you can get cows bred early. If all of your cows are cycling you can just run all the cows through the chute and give them a shot of prostaglandin 5 days after you turn the bulls out. If you’ve got some later calving cows that may not have yet returned to estrus, you can use a CIDR to jump-start their cycle. As long as its been more than 20 days since they calved you can use a 7 day CIDR synchronization protocol and either AI them or turn out the bulls.

Dr. Funston had a project where they estimate they moved late calving cows up in the calving season by 30 days. You do the math for yourself and your ranch, but if this year’s calving season was more spread out than you would like, then synchronization is a tool you might want to consider.

As always, you can call the extension office at 402-376-1850 for more information.
