White-tailed deer researchers at the LSU AgCenter Bob R. Jones Idlewild Research Station in Clinton are using sperm from dead bucks to keep their favorable genes alive.
Dearl Sanders, LSU AgCenter professor and resident director, and Will Forbes, his research associate, are awaiting the arrival of fawns that were fathered by a trophy buck that was killed in Illinois last November.
“We bred 16 does with sperm from this buck, of which six got pregnant and should be delivering in the next two to three weeks,” Sanders said.
This is not the first time that sperm from fair chased (legally harvested) bucks has been used to produce offspring, but it is the first time an out of state buck has been involved.
The record buck was killed by Louisiana hunter Mike Toney at Jerry Stafford's Samson Whitetail Mountain ranch in Vienna, Illinois.
Once the buck was down, care had to be taken with its testicles to insure the sperm survived.
“The most important part of the process is cooling the testicles down slowly in order to insure survival of the sperm,” Forbes said.
Forbes said Toney did a good job of packing the testicles and making the drive back to Louisiana with enough viable sperm to potentially breed 200 does.
“Mike delivered the testicles to Jesse Saenzs in New Orleans, who extracted the sperm and brought it to GenX Cooperative, a beef and dairy semen supplier in Baton Rouge to have it processed into almost 200 straws or individual doses,” Forbes said.
“Many hunters are looking at this new technology only as a way to grow white-tails with bigger racks,” Sanders said. “But that is just part of the importance of this research.”
In addition to growing trophy-sized deer, this research also may be the beginning of a new disease-control measure as well as a way to keep some species from becoming extinct.
