Each month, cow-calf producers are faced with management tasks related to seasonal and production goals. Jason Warner, Kansas State University Extension cow-calf specialist, summarizes the top 10 management practices producers should check off their to-do lists in October.

1. The time is here to wean spring-born calves. Are you ready?

  • If you’re going to retain them, know your cost of gain versus the value of gain.
  • Prepare pens, check waterers and have your health protocols in place.

2. Don’t misread your cows. Evaluate body condition scores (BCS) closely at weaning.

  • Make a record of BCS at weaning.
  • Use BCS to be strategic with your feed dollars this fall.

3. Take time to schedule pregnancy checks on cows and heifers.

  • This allows for other herd health problems to be identified.
  • Track conception rates yearly to gauge herd performance.

4. Work through your cull pen.

5. Remember the fall calvers.

  • Review your calving health protocols as needed.
  • Locate and clean your calving equipment.

6. Plan your mineral needs for fall and winter.

  • Record the date and the amount offered, then calculate herd consumption.
  • If consumption is two to three times the target, then your cost is too.

7. Keep an eye on your herd bulls.

  • Conduct a breeding soundness exam (BSE) on bulls to be used for upcoming fall service.
  • Supplement thin bulls coming out of cows to regain condition.

8. Heifers are worth a lot, so let’s manage them as such.

  • Know your target weight at breeding and grow them appropriately.
  • Target 2-year-old heifers to be at a minimum BCS of 6 at calving.

9. Take inventory of and begin sampling harvested forages.

  • Test for nitrates and prussic acid when appropriate.
  • Be aware of the possible presence of molds and other anti-nutritional compounds in hay that has been harvested at higher-than-typical moisture levels.

10. If grazing crop residues following harvest, keep the following in mind:

  • Nitrates accumulate in the bottom one-third of the stalk.
  • High amounts of down grain (≥ 20 bu./acre) will require a change in management.
