A bioeconomic simulation model for a hierarchical swine breeding structure
Article Abstract:
A computer simulation model composed of nucleus, multiplier, and commercial tiers for the production of market hogs in a three-breed, static breeding scheme was developed. Genetic, heterotic, environmental, and economic parameters were considered to facilitate selection, culling, and management decisions. This model may be applied in a national herd, a regional collection of moderately sized herds, or the herd production capabilities of a single corporation.

Genetic and economic analyses of female replacement rates in the dam-daughter pathway of a hierarchical swine breeding structure
Article Abstract:
The effect of culling sows at various parities in a tiered breeding structure on genetic change and returns was studied by means of a stochastic life-cycle swine production model. Alternative combinations of sow culling were evaluated by analyzing selection responses and returns per gilt to the breeder. The economic implications of the results of various selection and culling decisions are discussed.
