March is tough on cows; be prepared

Here are some tips to reduce cattle deaths and promote wellness.

March could be the hardest month of the year on beef cattle, said Eldon Cole, field specialist in livestock with University of Missouri Extension.

Why would March be worse than the other 11 months? Cole says there are several reasons for the difference.

  1. Calving time. March is likely the month with the highest number of cows calving in it. "With calving, we have difficult deliveries and mortalities of both the cows and calves," Cole says.
  2. Hay problems. Another reason is it is the end of the winter, and the feed supply leading up to it is not the best in quantity and quality. "This winter, most cattle producers monitored their hay supply very closely and testing has revealed nutrient values to be somewhat lower this year since all kinds of unusual hay was put up, almost in desperation in 2018," Cole says. The low-quality hay or other stored forage results in cows losing body condition.
  3. Deteriorating body condition. A body condition score amounts to about 80 pounds of actual weight on a cow. A mature cow with a BCS of 5 in November and December could easily lose 80 pounds by March. Thin cows at 4 and lower BCS will have lower-quality colostrum for the nursing calf. "The thin, poor condition cows suffer more from the damp, chilly, muddy weather often seen in March,” Cole says. β€œIt can result in deaths of cows with the sole comment about why they died being that she just looked like she ran out of gas.”

Take precautions

This year, more than normal, Cole says to plan to supplement hay with a high-energy supplement, either corn, corn gluten feed or dried distillers grain. The amount fed may range from five to eight per cow, per day.

Cole says there are other tips that can help keep beef herd mortalities low, including:

  • Feed some alfalfa hay.
  • Provide a creep area for calves to escape into to get out of the mud.
  • Move bale rings regularly for sanitation purposes.
  • Group newborns and their mothers apart from older calves.
  • If you have a scours outbreak in a pasture, do the feeding and other chores in that pasture last.
  • Be sure to thoroughly wash and sanitize your boots and clothing before going to a "clean" pasture.
  • Treat sick animals immediately after finding them.
