The role of sustainable commercial pig and poultry breeding for food security.

摘要

This article discusses how food security amidst increasing global population can be improved by poultry and pig selective breeding, changing animal populations over time and developing breeds and crossbreeds to express genetic potential in commercial environments. Focus is given on breeding goals (meat and egg production), constraints (feed availability, environmental load and animal welfare) to food security objectives and restrictions (genotype by environment interaction, antagonism between traits and possible loss of genetic variation).
