How do you see the future of newer technologies such as cloning, gene mapping, sexed semen, in vitro fertilization, etc?
The operative word is “new.” At one time AI and ET were considered “new” technologies. All of these technologies have a future. It appears that these applications are appropriate for a narrower group of genetic donors. AI is appropriate for a large number of cattle. ET is appropriate for no more than 10% of the AI group, etc. IVF and Cloning promise less expensive production of embryos, but pregnancy rates and calving problems presently make them costlier on a per heifer calf basis. Not if, but WHEN those problems are addressed, then IVF and cloning will likely increase. I’m reluctant to embrace the value proposition in the narrowing genetic pool cloning will offer…but that’s just me. Gene mapping offers a great tool to associate desirable traits with specific genes. That holds true as long as we’re sure about what traits are desirable. Remember the early 90’s? “Who needs fat? All we want is protein.” That worked really well didn’t it? I’ve saved sexed semen for last. This holds a lot
