|Virtual Tour - NAGP
Samples are collected from animals from all over the U.S.
|Shorthorn cows in Nebraska.|| |
| || Navajo Churro sheep in Arizona.|
|Upon arrival, sample viability is evaluated using computer assisted sperm analysis (CASA). || |
Semen samples are cooled to 5?C and cryoprotectants are added. Samples are then packaged with an automated straw filler and labeler.
| ||Example of filled, sealed and labeled straws ready to be cryopreserved.|
< Straws are cooled to -140?C using a programmed cooling apparatus, and then they are plunged into LN2.
Once samples have received proper cooling treatments, they are placed in cryovats for long term storage. >
| ||Information about sample provenance and semen storage location is entered into the Animal-GRIN database.|
