Analyzing Populationsheadline bar /ARSUserFiles/30123030/images/Holstein calves Penn State (Amy Duke) small.jpg/ARSUserFiles/30123030/images/dexter calf jamie ocallen x nora born10142014 jody jess 200.jpg/ARSUserFiles/30123030/images/baby pigs Purdue112007 200.jpg   The repository can be used to completely rebuild populations, perform corrective matings, or reintroduce lost bloodlines/broaden the genetic base. Holstein calves were generated in collaboration with Penn State, TransOva, and Select Sires to broaden the genetic base of the Holstein breed by reintroducing lost lineages
This Dexter calf is the offspring of Jamie O'Callen, a 1977 born bull provided by NAGP for udder improvement and maintenance of genetic diversity of the breed
The baby pigs are the progeny resulting from a complete line reintroduction by Purdue University as part of an effort to study a human disease
Native Shorthorns born in the 1950's were provided to a breeder to broaden their herd's genetic base; semen from sons was collected and donated to NAGP An important part of the NAGP mission is to increase genetic understanding of U.S. livestock: GIS: Navajo Churro (PDF) Pedigree & Cluster Analysis, Dairy Goats (PDF), Pigs (PDF) Expected Progeny Differences (EPD) Graphs Molecular Analysis: Sheep (PDF) Goats (PDF) Pigs: Meishan (PDF) Multi-breed Autosomal Analysis (PDF) Multi-breed Y Chromosome Analysis (PDF)
