The cell donor for Dello's Double is Dello *Ennobled* who had an impressive record including two national titles. She was the 1999 ABGA National Reserve Grand Champion Boer Doe and the 2000 ABGA National Grand Champion Boer Doe. Downen Livestock purchased Dello *Ennobled* at the Ward dispersal sale with the intentions of cloning her in the future. Dello *Ennobled* was subsequently flushed to Pipeline *Ennobled* in the fall of 2001. She produced 39 grade one embryos with 28 flush offspring kidding out. She was bred back to Pipeline for natural progeny and she kidded with triplets in April of 2002.
Dello *Ennobled* died three days later from pregnancy disease. Fortunately tissue from her had been banked soon after she arrived at the Downen farm. As the kids grew and developed their quality made it obvious to the Downens that a cloning program should be undertaken.
The Downens are becoming old hands at this cloning thing...
"In the fall of 2000 we worked on the first clone project producing our clone from TX63 684 who was named TX63 684 Second Edition ("Megan") who was born in March 2001. Dr. Mark Westhusin, Dr Chuck Long, and Dr Lin Lu performed the nuclear transfers at Texas A&M. The embryos were transported to our farm in Early where they were implanted into our recipient does."
That first successful cloning procedure had required 300 embryos to produce "Megan". Dello's Double is the product of only 70 embryos. Obviously the process is becoming more precise and productive.
Clones are genetically the same as their cell donor but are really new animals - the donor and clone are essentially identical twins. Clones are registered as unique individuals and their registration certificates designate them as clones. Cloning is a tool we can use to retrieve genetics from the past if done properly. "It is best to bank tissue on animals before they die and have it cultured and stored properly. Then at a time when we want, we can enter into a cloning project with the intention of producing animals that will benefit our breeding program".
