The Rural Voice, 1992-06, Page 27evaluations ever undertaken. Weaner pigs from each source were raised under similar conditions at the university. They were put under intense scrutiny with some of the best equipment money could buy. Feed conversion was monitored. Equipment for Eve animal measurement was used. More than 300 measures were made on each animal. The animals were slaughtered at various weights, 55 lb., 100 Ib., three groupings in the 100-200 range, several more groups in the 200-300 range and a group at 330 lb. Carcasses were measured carefully, testing both the quality of the animal and the accuracy of the measuring equipment used on the live animals. Even the blood from each animal was weighed and analyzed to see if there were characteristics that set off the best animals from the ordinary. The Canadian animals, Warren Stein says with just a hint of pride, were superior on lean percentage and lean gain to the American hogs. Colour photos on a display in the Thames Bend board -room show a cut from a Stein pig in the study with a thin layer of fat over a large muscle, compared to a huge slice of fat on an American counterpart. Canadian pigs, Stein points out, generally go to market at about 220 pounds compared to 280 for their American counterparts, but the 220 pound Canadian carcasses still had as many pounds of lean meat as the 280 pound U.S. animals. What's more, Stein says, "Our pigs can be taken to 270-280 pounds and still be lean." Warren Stein says he and Richard and the 16 employees at Thames Bend can take credit for diligence in applying the information available from the Canadian record of performance testing system, but all Canadians can take pride in having those programs in place to allow for the advances in genetics. The difference between American and Canadian pork production can be traced back to our history, he says. Canada was in the two World Wars before the Americans. With Britain at war in 1914, the Canadian government, packers and farmers got together to decide how to meet the challenge of feeding both Britain and Bend Purdue Unv noes CARCASS AND WE ANIMAL EVALUATION Ailey ?( dor WIMP MLA the millions of troops. The British knew what they expected a pig to be and the Canadian industry teamed up to meet those needs. "It gave us a legacy of working together and programs that allowed us to manipulate production," Stein says. In World War II the same teamwork was in evidence as four out of five pigs produced in Canada were exported (with the side effect that after both wars Canadian pork producers suffered through too much production capacity for the reduced markets). Marlow Gingerich, a young Centralia College grad from Zurich, shows the latest weapons Thames Bend puts to work in the name of genetic improvement. A cart contains a television monitor and a strange, curved wand. It's an ultra sound machine, identical to the kind used in hospitals to study unborn children in their mother's womb. Here though, the machine is used to look through Iwo Warren Stein shows photos from the Purdue University study. are recorded on a video tape. The tapes arc taken into the office where they're played back through a tape -player into a computer. The images are stopped at the standard measuring points and the computer measures the back -fat thickness and, in some cases, the muscle mass. Later that information is key -boarded into a Lotus 1-2-3 program of record keeping. Again, the records of about 25 pigs can be entered in an hour. The information allows Thames Bcnd to get information that in the past wouldn't have been available until an animal had been slaughtered. *** Warren Stein feels a sense of excitement about his business, even after 25 years of building it to thc way it is today. "Nobody else is doing what we're doing today." The new technology available to breeders like Thames Bend today is one of the greatest tools in improving breeding programs. "You do something for 25 years and make progress and all of a sudden it's like falling into Alice's Wonderland," Stein says of thc high-tech world now available. He knows something about changing technology and its effect on genetics. Genetic selection took a great leap forward in thc 1980s when Two industry a legacy of co-ooperation World Wars gave the Canadian pork the skin of pigs and see just how much lean meat and fat there is.
