Dr. Keit Bediri from Via Pax, the whole concept has not been pushed far enough. Over 140 members of the Huron County Holstein club listened to Dr. Bediri tell of, the advancements in the field of non surgical embryo tran- sfers, at their annual meeting in Belgrave, Friday. ThiS method of breeding is not a riew concept. The first `embryonic transfers were 490*, in Cambridge, England it 90 with rabbits to deter- mine if recipient mothers could genetically effeci embryos. In the 1930's lab animals were raised by this method, and in 1951 the first calf was born in an experimental dairy herd. It was not until 1969-70 that more reports concerning embryo trans- plants were received. "At present doctors are finding a 90% success rate for surgical embryo trans- plants." Dr. Bediri said. Dr. Bediri pointed out that with the introduction of exotic cattle in Canada re- search has advanced con- siderably. "These breeds (exotic) de- manded high prices. "said Dr Bediri "They had ,to be brought into Canada and the second generation could then be exported to the States which did not allow for importation of cattle from `other countries." Too Long "The long quarentine made it too long to wait for Correspondent Mrs. Joe Walker 357-3558 Celebrating an early Christmas on Sunday at the home of, Mr. and Mrs. Alex MacTavish were Mr. and Mrs. John K.

So cattle were super ovulated and the eggs were flushed out and placed in recipient cows already in the country." Dr. Bediri said. The situation was ideal for experimentation for those who were willing to take the risk, said Dr. Bediri. "What would have taken years was done in a much shorter time -period." For established breeds in Canada this method of developing herds would lead to better stock and for larger berth to be sold abroad. He said. It was discovered that surgery was hard on dairy cattle due to their build and the amount of stress they can stand. Therefore the method of surgically implanting the emb , vos was changed to a lower lank k\ ith local an- esthesia from the earlier method of general anesthesia and the cow turned on her back. • Non Surgical "Now almost all com- mercial companies are em- ploying non-surgical methods of embryo trans- planting." said Dr. Bediri. The process is extremely simple. '1 he chosen cow is programmed by the intro- duction of hormones to cause the ovaries to super ovulate. "The ovaries swell and must now not be confused with cysts" Dr. Bediri said. Dr. Bediri favoured hormones taken from the pituitary gland of pigs as oppdsed to cows which is low Grant, Mr. and Mrs. Don Dossnan, Kevin and Sherri, of St. Clements, Mr. and Mrs. Jack Willitts & Ray of Wroxeter, Miss Norma Willitts of.

The food and drug depart- ment requires milk to be withheld whenPMS (pregnant mares) is used. If the FSH (pituitary gland homone) is used there is no witholding. Both the biological mother and the recipient mothers must be induced into heat at the same time. "The embryos may be kept alive for one day, or they can be frozen." said Dr. Bediri. "We have a 65 per cent conception rate and if freezing occurs the rate drops to 40 to 50 percent." There are some draw backs. Dr. Bediri pointed 25% of the embryos are lost because of their fragile nature. "It is also expensive and there are not that many highly skilled people available to do the job." said Dr. Bediri. "Embryos can only be frozen on the seventh day." "Some farmers could .pro- fit from this procedure but it is still an expensive pro- position." Said Dr. Bediri. Dr. Bediri suggested that in the future there will be small mobile units travelling to the farms making Embryo transplant accessible to the average farmer. There were questions raised about the sexing of the embryos before being im- planted so that farmers would not be wasting their time with bulls when heifers were the order of the day.. "Embryos can be sexed at 16 days by looking a sliver, of tissue under the micro- scope." Dr. Bediri salt' "But that is too late for implanting the embryo." Sexing semen is a harder problem. PH levels have been checked. Electric fields and gravity pulls among other methods have been used but there is still nothing conclusive." said Dr. Bediri. Bluevale It forces the manure from the barn, through an underground pipe to the storage area. As the manure enters storage area from below, the outside surface forms a crust, which retains the important nitrogen and potassium inside the pile and also reduces the odor and fly problems. And manure is ready for spreading, when you want it, For details call Keith Siemon Plumbing — Farm Equipment RR.4, Walton, Ontario Phone 3454734
