Quantitative Selection for Piglet Survival as A Safe Way to Reduce the Cost of Weaners
By Egbert Frank Knol - In this paper, first presented at the 2003 Banff Pork Seminar, trait piglet survival is explored using quantitative methods, searching for genetic variation (Knol, 2001) and for biological explanations for possible genetic differences...

Cost Effective Boar Usage
By Mark White, BVSc DPM MRCVS, England - Back in the 1980???s when artificial insemination usage was more the exception than the norm for mating sows, the major issues for boar usage were avoiding overuse and maintaining consistent usage with particular...
