[QUOTE="whitecow, post: 571940, member: 8638"] What technology was used to clone the following animal if the patent of the Rosilin Institute was file in the mid to late 90s? "......As females, 8020s are very-balanced, structurally-sound replacement heifers and young cows with perfect, sound udders and milk. His daughters and granddaughters are great brood cows in many reputation herds. But it’s rare they come up for sale; the Oxley sale no longer offers them. One of the highest selling horned Hereford females in 2000 was an 8020 daughter, bringing $7,000 in Nebraska’s Messersmith sale. "The big thing about 8020 is he sires cows that are very feminine and very productive with good milk and good udders," Schafer says. "People just love the daughters in their cow herds." Of the many good females around the country, Schafer believes that one of the most notable is K-State’s direct 8020 daughter, Miss Mark K 111. "We feel that she’s quite possibly one of the best Hereford cows in the breed," Marple says. And that’s one of the main reasons K-State has gone back to 8020. "When I started doing some number crunching on different things, 8020 was one of the few bulls that sorted himself out on the maternal side," Marple explains. "Our goal and focus is to put 8020 daughters back into this cow herd." [b]111 is now 11 years old and is one of two cows—the other an Angus—that’s been cloned at K-State. She is the dam of KSU Miss Blaze 014 ET, Star Lake’s 2002 Denver Champion Horned Heifer[/b]........
