The Rural Voice, 1990-09, Page 34THE BEEF INDUSTRY: Charting a Successful Course Lloyd Mitchell is convinced that crossbred cattle are the breed of the future. And he has developed a breed- ing strategy to improve his cow/calf herd and create ideal performance - tested crossbred cattle on his Annan - area farm, near Owen Sound. Using cross -breeding to get hybrid vigor, Mitchell is breeding cattle that will use home-grown roughages to produce an A 1 carcass of 700 pounds at 12 to 15 months of age. Developing an ideal cross is a slow process, usually of trial and er- ror, but Mitchell is pleased with the results from his Shorthorn/Salers cross. While nearly all breeds are represented in his 95 -cow herd, the 45 purebred Shorthorns have a majority. Several factors drew him to the Short- horns, including their good milking ability, fast growth, easy calving, and consistent calf size. But choosing the Salers was quite accidental: Mitchell knew very little about the breed until he purchased Shorthorn cows which were bred Salers. When Mitchell builds his herd up to 120 cows, he hopes to develop an F1 heifer market, similar to the hog industry, from his Shorthorn/Salcrs cross, based on performance and repu- tation. Now he keeps the best of the heifer offspring from the FI cross and breeds them to Charolais bulls because he likes the Charolais rate of gain. The results speak for themselves. The herd's average weaning weight has increased by nearly 100 pounds in 4 years, while the average yearling weight has increased by 150 pounds. In one example, a Shorthorn heifer born in 1984, with a weaning weight of 490 and yearling weight of 760, was bred to a Salers bull and produced a heifer that weighed 640 pounds when weaned and 840 pounds as a yearling. This heifer then had a calf with a weaning weight of 676 pounds and yearling weight of 1,112 when bred to a Charolais bull. Mitchell used Charolais cows in his initial breeding program but found they lacked fertility, had calving dif- ficulty, and weren't good mothers. Fertility and calving ease are impor- tant factors in Mitchell's breeding program. His cows are checked for pregnancy in the fall and culled if still open after the 60 -day breeding season. He also takes the pelvic measurements of potential breeding Lloyd Mitchell's success in the beef industry is founded on a sound breeding strategy and a feeding program featuring home-grown roughages. His results speak for themselves. story and photos by Mary Lou Weiser -Hamilton heifers each spring to help determine their calving ease. When Dr. Alex Strong (Wingham) measured pelvises in 1989, Mitchell had him test a Charolais for compar- ison with the Salcrs heifers. After examining the results, Mitchell felt he was making the right breed choices. A 635 -pound Shorthorn/Salers heifer had a 189 cm2 pelvis while a 1,075 - pound Charolais had a 182 cm2 pelvis, despite the fact that she was 45 days older and 440 pounds heavier. Both were on the same feeding program. In 1989, Mitchell kept 11 Short- horn/Salers heifers and two Hereford/ Salers heifers which he bred Charo- lais, and three Shorthorns which he bred Salers. With the exception of three "easy pulls," none of which re- quired a calf puller, the hcifers calved by themselves with birth weights ranging from 62 to 103 pounds. "The Salers seem to have the pelvic opening to handle big calves," he says. All heifers are kept from the time they are weaned in late fall until spring. Replacements are then selected to go to pasture and stay with the bull from May 1 to June 30. The remainder are either sold or finished. 30 THE RURAL VOICE
