  • Producers share their experiences with cloningCassidy Woolsey for Progressive Cattleman

    If you could keep an exact copy of your most valuable bull or elite cow, would you? Lets say your top-producing animal died tomorrow: Would you shed a few tears and conjure up a few cuss words, or would you simply redeem the animals cell line and produce another?

    Whatever your choice, somatic cell nuclear transfer, otherwise known as cloning technology can provide

    a way for a genetic legacy to live on. And that is exactly what some beef producers across the country are doing.

    Recapturing the prizeMark Mueller, owner of Diamond

    M Cattle Company in Hiawatha, Kansas, says his decision to clone his renowned cow, Blaze II 5T, was an easy one. After seven years of

    winning multiple livestock shows and accumulating close to $750,000 in embryo and live-calf sales, Mueller fi gured cloning could be a good investment.

    Th is particular cow has made us more money than any other cow on our operation, Mueller says. So preserving her genetics seemed like a good decision to me. Th is way, we can still have those genetics that took many years to build long after Blaze is gone.

    For nearly four decades, the Diamond M Cattle Company has run an intensive embryo program and has provided breeding stock to producers across the country. In recent years, the Mueller family decided to incorporate a show calf segment to diversify their business. Because of the nature of their business, exceptional genetics is vital to their success.

    So in the fall of 2012, Muellers fi rst and only clone was born charcoal black with a white-snipped face, unmistakably identical to the original.

    Since then, the clone has been bred and is scheduled to calve this spring. Mueller says afterward he plans to fl ush her and embryo transfer her, just like he has done with the

    original cow. He is optimistic that her off spring will be just as good or better than the original.

    It is all about bettering our genetics, Mueller says. To go out and buy another female like the original cow is usually going to cost you as much or more than what the clone will. So why not be able to get the same genetics you know work and clone the one you have?

    Although Mueller is pleased with the results of his clone, he points out that cloning doesnt come without risk. He says he started this cloning project with an industry partner to produce two clones; in the end Muellers clone was the only one that was born.

    You can get a lot of money wrapped up into cloning. Th e only reason I felt that it was feasible for my operation is because of the money Blaze had made over the years. I felt that I could invest some money into furthering our genetics, he says.

  • owner of SEK Genetics. Coover says outside of his semen distribution company, cloning technology has given him access to exceptional genetics he otherwise wouldnt have been able to introduce into his own cattle operation.

    Th ese cows that I cloned were high-profi le cows that had a really good production history behind them, Coover says. I contacted the owners and asked them if they would let me clone their cows at no charge to them. But in return they would get half of the genetic interest in them. So in other words, I would make the clone, make the embryos, sell the embryos and split the profi t with the owner, but I get to keep the cow.

    In accordance with his plan, Coover was able to add 10 clones to his cattle operation over the course of 15 years. He felt these particular cows justifi ed the expense of cloning because they had already proven their worth and provided valuable genetics to the industry, he says. Th is plan essentially provided Coover an opportunity to gain access to specifi c animals he otherwise wouldnt have been able to aff ord if it wasnt for his shared genetic ownership.

    I have always been interested in

    trying new technologies, so this plan was a good fi t for me, he says.

    Coover strongly believes one day producers will use cloning just like any other technology. He says there is no reason to be afraid of cloning it is an advanced reproductive technology

    similar to A.I., in vitro fertilization and embryo transfer. Right now, it is just dramatically inhibited because of the patent on the technology, he says.

    If the technology becomes more effi cient, and hopefully much cheaper, it will become more useful to the

    The two most critical times of the year for proper trace mineral and vitamin supplementation in your cow herd are prior to calving and prior to breeding. With many forages, protein supplementation will also be needed at this time. CRYSTALYX Breed-Up products differ from the more standard CRYSTALYX supplements in three ways; higher levels of vitamins, more concentrated levels of trace minerals and all CRYSTALYX Breed-Up supplements contain organic forms of trace minerals. Your future looks bright with CRYSTALYX.

  • J.R. Simplot Company has been taking promising technologies and implementing them into their varied programs. In fact, innovation is a large contributor to their renowned success, says Brady Hicks, a cattle research manager for Simplot.

    With close to 30,000 head of cattle divided on 14 diff erent ranches across the U.S., Simplot is known as one of the largest beef producers in the U.S. Among the many diversifi ed segments of Simplot is a custom-feeding operation, heifer replacement program and two major feedlots which can hold a one-time capacity of 150,000 calves.

    When Mr. Simplot started this company, he was always trying something new, and that is what got us to this point, Hicks says. Cloning was later one of those things we decided to try, and it was an eff ective tool for many years.

    Hicks says for a few years they cloned cows both on the ranch and in the feedlots. Th ey would look for certain characteristics in cattle that had just come off the desert range, such as longevity and good calf production. Th e cows that lasted longer than the average life expectancy and were still producing quality cattle were good candidates for cloning, he says. Th ey also used the same standards in their feedlots but looked for traits such as prime, yield grade 1.

    Th e technology in itself doesnt produce the best animal; you have to fi nd that animal, an animal that has all of the pieces in the right package, Hicks says. And then cloning technology just replicates it; it makes an identical twin separated in time.

    For Simplot, it was a matter of keeping the animals that had an economic value to them rather than replacing the old with a new line of heifers. Th e set of characteristics they are looking for is rare, and there is something about that animal that has been selected by its environment to withstand the frailties of old age, he says.

    Simplot is currently still utilizing the clones and their genetics, but they are no longer actively cloning, Hicks says. Because of the current cattle prices, cloning is not economically feasible for their company unless it is an extreme animal that is right for production. However, when cattle prices drop, Hicks says they will probably start using cloning technology again.

    In their opinionSmall scale or large scale,

    these three cattlemen believe this advanced reproductive technology can be a good investment if the animal is worth the expense. It also provides a way for producers to secure a cell line of an animal that is valuable but hasnt quite proven its worth to the point of cloning. Th is way, if something were to happen to the animal later on, it can still be cloned.

    Th is technology holds great promise to the future of the industry, Coover says. It is nothing to be afraid of. Youre producing a copy of something that was naturally produced; it is not too far from natural-occurring clones which we call identical twins.

    Like any technology it has some risk, but according to these three cattlemen, it has been well worth the gamble.
