Area of Science:

  • Animal Science
  • Agricultural Economics
  • Veterinary Medicine

Background:

  • The longevity of sows and boars significantly impacts herd productivity and economic viability.
  • Effective herd management requires strategic culling programs to maintain optimal breeding populations.

Purpose of the Study:

  • To outline the importance of tailored culling programs for swine herds.
  • To provide a framework for evaluating and improving breeding animal longevity.

Main Methods:

  • Regularly evaluate existing removal policies.
  • Estimate the longevity of breeding animals (sows and boars).
  • Calculate nonproductive sow days associated with culling.
  • Determine primary causes of culling and death within the herd.

Main Results:

  • Identifying longevity problems and their extent is the first step toward correction.
  • Understanding underlying issues and predisposing factors facilitates targeted interventions.

Conclusions:

  • Customized culling programs are essential for maximizing sow and boar longevity.
  • Systematic evaluation of removal policies and mortality causes enables producers to address longevity challenges effectively.
