After a long, cold and soggy winter, Kentucky cattle producers, and their spring calving cows and newborns, finally see relief.

But does the arrival of spring really put producers “over the hump?” Perhaps, but producers do have some pressing concerns, said Roy Burris, University of Kentucky College of Agriculture, Food and Environment beef specialist.

Most cows need to improve body condition, so they will be able to sustain a pregnancy, and producers want to get cows bred in the next few weeks. Since feed was in short supply, most producers likely turned their herds out to grass as soon as it appeared, but lush, watery grass will not sustain milk production and weight gain.

“Producers need to continue to provide energy supplementation a little longer,” Burris said. “The goal is to have cows at a condition score of near 5 (ribs covered) at the start of the breeding season. If cows are not pregnant before extreme heat sets in (late June or early July), pregnancy rates will likely be very low.”

Burris recommended that producers continue to feed a high magnesium supplement until the soil temperature warms up.

“Don’t skip magnesium supplementation – regardless of what you read,” he warned. “Research conducted at the UK Research and Education Center in Princeton showed that 1.5 ounces of magnesium (22 grams) would prevent grass tetany in high risk situations. When it was left out of the mineral mix, grass tetany would appear as predicted. A mineral supplement with about 14 percent magnesium should be adequate with normal consumption.”

Producers should look at reseeding pasture areas that were trampled to the point of killing the grass. Weeds like pigweed (spiny amaranth) will encroach on high traffic areas.

Burris said the short term is not the only thing to consider. “Was this last winter an aberration, or a harbinger of things to come? Since cows and calves represent a substantial financial outlay and for humane reasons, we need to re-evaluate some of our practices and consider some changes.”

Producers could shift their calving season to the fall, when weather isn’t a problem to calf survival. Pregnancy rates and calf survival are generally higher in fall than in the spring. Even though feed costs are traditionally higher in the fall, it’s still a viable option.

Producers who decide to stick with spring calving should make every effort to be successful, and that could mean it may be time to consider more shelter or protection for cows and calves.
