Vorkshop for photography wet for Feb. 7 By WAYNE COOK Battalion Reporter A procedure involving superovu lation and embryo transfer has re volutionized animal reproduction, and it is the basis for a growing indus try, a Texas A&M University animal researcher says. Dr. Duane C. Kraemer, a profes sor of veterinary physiology and animal science at Texas A&M, and colleagues performed the world’s first embryo transfers on baboons, dogs and cats. The technique begins by treating a donor female with hormones to cause expulsion from the ovary of numerous ova instead of the usual one ovum. The donor is then insemi nated, most often artificially, to fer tilize the eggs. And within a week, the resulting embryos are removed nonsurgically by flushing the uterus with a special fluid. The embryos are then transferred to the uterus of the host female the same way they were recovered. This technique is used primarily to increase the reproductive rate of valuable animals, Kraemer said. Genetic progress is slowed by the low reproductive rate of most animals. “I don’t know of any species in which embryo transfers have not worked if attempted with determina tion,” Kraemer said. Embryo transfer has been success ful in 15 or 16 different species of animals including baboons. The first embryo transfer occurred with rab bits 90 years ago in England. The success rate of the transfers varies from one species to another, Kraemer said. Embryo transfers are done most often with cattle, where 60 percent of the embryos implant ed result in calves. When hormones are given to the donor, three to four calves result per collection of the embryos. In North America alone, about 17,000 pregnancies were produced in cows by superovulation and em bryo transfer in 1979.

Transfer units currently charge approximately $2,000 for each calf produced. Some believe the offspring should be worth at least $4,000 to be profitable, Kraemer said. “The price makes it (embryo transfer) impractical for common an imals,” Kraemer said. ‘‘But that’s OK, we shouldn’t be. reproducing anything but the best. ” The technique of transferring em bryos may soon be applied to hu mans, Kraemer said. Although he is not involved with this area, he has discussed it with Chicago surgeon Dr. Randolph W. Seed, who plans to transfer the first human embryo by 1982. The results of embryo transferring may be great, including replenishing species that were once endangered and, eventually, a healthier animal population. Fund should stay same? > t l o United Press International AUSTIN — A Senate subcommit tee today approved Gov. Bill Cle ments’ appointment of three Texas A&M graduates to the Board of Re gents of their alma mater. The appointments now go the Senate for confirmation. The three prospective new re gents are businessman Harvey Roberts Bright of Dallas, attorney William A. McKenzie of Dallas, and oil and gas operator Joe C. Richard son Jr., of Amarillo. Sen. Chet Brooks, D-Pasadena, asked the three appointees how they feel about spreading the endowment of the Permanent University Fund among other institutions in the Texas A&M and University of Texas sys tems. “I favor spreading the PUF funds through the system requirements,” Bright said. McKenzie said he agreed with Bright and said that “PUF should be left for the purpose of excellence in education at the University of Texas and Texas A&M.” “How about excellence in educa tion at some 23 other other institu tions such as Stephen F. Austin and Sam Houston State College,” asked Sen. Roy Blake, D-Nacogdoches. “The Legislature should bring forth a plan to bring forth funds to make those institutions excellent,” McKenzie said. “I don’t think you should steal from one to give to the other. ” Richardson told the subcommit tee, “I don’t know all I need to know about that yet.” The subcommittee also approved the re-appointment of Alton Bowen as state commissioner of education. Bowen said the teaching of the fundamentals of education — read ing, writing and arithmatic — is the most important problem facing Texas schools. He also said he favors competency tests for teachers, be fore they begin their teacher educa tion and again before they are certi fied to teach. save energy a very bright idea : >» ;i s £ c J5 o c c - c: : <D .t CD I > C/ fe £ DON’T FORGET!!
