Application of Selection Concepts for Genetic Improvement
Publish Date: June 3, 2006
Correct use of selection concepts is essential if genetic improvement is to proceed at a rapid rate. Therefore, seedstock breeders and commercial pork producers need to fully understand the principles of selection which directly influence the amount of genetic improvement made per year. This fact sheet explains the primary concepts necessary to gain an understanding of genetic improvement. Then it discusses the effect of applying selection concepts on genetic improvement.

Across-Herd Genetic Evaluation of Swine
Publish Date: June 3, 2006
One way to improve performance in a herd is through selection of genetically superior animals, with the selection based on an estimate of the genetic merit of the animals. How well this genetic merit is estimated (accuracy) is important, because accuracy predicts the potential rate of genetic progress. The higher the accuracy, the more genetic progress is possible, assuming that the genetically superior animals have been selected.
