We have often pointed out on this blog that it would be advisable to collect and stick into genebanks the local varieties found in a particular locality, 1 especially the ones found only at that locality, before introducing new diversity, no matter how much “better” that new diversity might be considered to be just now. In fact, I kind of made that point just a couple of days ago for sweet potato. So it is gratifying to find an example of just that, and nevermind that it’s from the livestock world.
The story is from an article by Dr Harvey Blackburn in the July issue of Hoard’s Dairyman. It’s kind of difficult to access online, but Corey Geiger, Assistant Managing Editor at Hoard’s, kindly allowed us to publish some excerpts. Dr Blackburn is coordinator of the USDA’s National Animal Germplasm Program (NAGP), based at the National Center for Genetic Resources Preservation in Ft. Collins, Colorado. His article is entitled “Isolated Jersey genetics are a treasure trove” and tells the story of how the Royal Jersey Agriculture and Horticultural Society entered into a partnership with NAGP to safegueard the genetic integrity of the Jersey cattle breed.
Jersey dairy cattle are found in at least 82 countries where they have made substantial contributions to animal agriculture. The progenitors of these cattle can still be found on Jersey Island. For over 219 years these cattle have been kept in genetic isolation from non-Jersey Island cattle — but this situation changed in 2008. The Royal Jersey Agriculture and Horticultural Society (RJA&HS) promoted and after evaluation by the States of Jersey parliament concluded that Jersey genetics could be imported and used on island Jersey cattle, with a proviso that they have an enhanced pedigree status of seven generations of recorded ancestry and no known other breed in the pedigree.
But that wasn’t the only proviso.
An important consideration in allowing the importation of Jersey genetics was the need to have semen safely cryopreserved and stored in a secure facility. By having such a reserve the RJA&HS could reintroduce the pre-importation genetic composition of Jersey cattle, if so desired. The RJA&HS found a secure facility and willing partner with the National Animal Germplasm Program (NAGP) located at the National Center for Genetic Resources Preservation in Ft. Collins, Colorado and part of USDA’s Agricultural Research Service. The NAGP has been developing germplasm collections for all livestock species for over 10 years and has amassed over 700,000 samples from more than 17,000 animals representing approximately 130 livestock breeds and over 100 commercial and research lines. Currently the collection has over 600 bulls from U. S. and Canadian Jersey populations. The program has also been used by researchers and industry alike to characterize and reestablish animal populations.
Samples from 400 Jersey bulls were sent in January 2012.
The States of Jersey and RJA&HS decision to allow importation while ensuring pre-importation genetics was safely preserved provides a model for how genetic variability can be preserved while enabling the livestock sector to make necessary changes to meet existing and future production challenges. In addition it is an example of how countries can be mutually supportive in conserving animal genetic resources through gene banking.
Amen to that.
