Avian genetic stock preservation: an industry perspective

Poultry Science
J E Fulton

Abstract

There are different types of poultry genetic resources including mutants, inbred lines, specialized/selected stocks, standard breeds, and elite commercial pure lines. These resources differ in their degree of value to the poultry industry. There is considerable concern within poultry breeding companies about the continuing losses of these genetic resources, particularly as this loss seems to have escalated over the past decade. Varied genetic stocks can provide fundamental information regarding gene function, genetic interactions, and genetic pathways. This information is important for efficient improvement of commercial poultry performance. Equally important is the role of these genetic resources in teaching and the education of students and future researchers. Currently, the only practical preservation method for birds in the poultry industry involves live bird conservation. Flocks of elite commercial stocks are maintained at multiple locations, providing insurance against disease outbreak and the possibility of quarantine restrictions. The current cryopreservation methods apply only to sperm. Thus, the W chromosome and the mitochondria, which are contributed by the female gamete, cannot be preserved. Cryopreserved semen show...Continue Reading
