| BOVIGEN, LLC Replaces IMMGEN Bovigen, LLC has been chosen by the APA Board to replace Immgen as the APA source for DNA testing. This decision was made because Immgen ceased operation. Bovigen, based in Harahan, LA is a genomics company that has developed a number of DNA products, aside from parentage testing. Because of their other products, they are offering APA members a package deal if Quality Grade and Tenderness DNA, and GeneSTAR diagnostic tests, are requested at the same time parentage is ordered. These results will then be sent to the requestor and the APA .
The cost of the program is a follows: According to APA rules, all bulls that have been collected for semen sales must have a DNA or bloodtype on file with the APA. ALl embryo calves must be DNA typed back to their donor parents before they can be registered with the APA |

DNA UPDATE BY PAUL SWISHER
As of Oct 06 there
have been a total 79 Pinzgauer cattle tested for GeneSTAR tenderness
markers. 67 animals tested GeneSTAR 2 Stars or better(84.8%) This is
better than Angus and Angus-X. Only 1 tested GeneSTAR 0(1.26%)
compared to 17% for Hereford
Tenderness is heritable, therefore TENDER SIRES HAVE TENDER CALVES. No single trait should be used to select sires but when you consider the docility of Pinzgauers, the mother ability, the early maturity, the climate adaptability and ease of maintenance, Tenderness should be the final straw for selecting PINZGAUERS. |
Pinzgauer T-Bone, GeneSTAR 2 Star tested daddy, and all the silverwear you need: two forks and a butter knife. Can't get any better than that |

No More "Tough" Steaks - Thanks to DNA "Tenderness" Testing Everyone is familiar with the advances made in DNA testing for humans but this technology is now being utilized for animals as well. At the Sunbelt Agricultural Exposition October 19-21, 2004, in Moultrie, GA, the Southern Pinzgauer Group will be conducting a seminar on the “DNA Tenderness Test” for beef cattle. Paul Swisher, Tenderness Coordinator for the American Pinzgauer Association, will give a “hands-on” demonstration of the proper way to collect the samples needed to DNA test a bull for tenderness. He will also cover the methods used to test female cattle and calves. “Think of the ways you could promote the calves your bull produced if you knew how tender the meat of his calves would be,” Swisher said. “And, the DNA test is a simple task which can be done during normal inoculations.” Swisher said the high-tech DNA testing starts with a low-tech sample--15 to 20 tail hairs (with the hair follicles attached) from the middle of the switch (the fat part of the tail hair). This hair sample is then placed in a test envelope and sent to a laboratory for a DNA mapping of tenderness. “We will have a good supply of the laboratory’s sample kits at the Sunbelt Expo,” he said. The laboratory process is identical to that used in human DNA testing, Swisher explained. In beef cattle, the DNA test can identify a cow’s parents. There is also a genetic marker for potential tenderness, which is an inherited trait. Two enzymes play a part, one inhibiting and one encouraging cell breakdown. There are markers for other traits--such as the color black, which is important in certain breeds, and the amount of marbling expected from the meat for USDA grading. According to Phil Peoples, also of the Southern Pinzgauer Group, a Carcass Tenderness report by the Meat Animal Research Center in Nebraska indicated four beef breeds-- Pinzgauer, Red Poll, South Devon, and Piedmontese—rated outstanding in the area of transmitting tenderness to the beef carcass, with the Pinzgauer coming in as “most tender.” A marketing study at Kansas State University revealed that consumers will pay $2.67 more per pound for guaranteed tender meat. A ranch in West Texas is already conducting tenderness tests, with the cows rated high in tenderness prepared as steak cuts while those that do not pass the test are ground into hamburger meat. “This ranch—by guaranteeing the meat’s tenderness--is getting $49.95 for two 8-ounce tenderloins and they can’t keep them in stock,” Swisher said. Two-thirds of all Americans have had an unsatisfactory experience at a restaurant serving “tough” meat, he added. “This is not meat that tasted bad. It is a direct reference to the quality of tenderness,” said Swisher. “This has created a trend toward private label or branded beef as opposed to mass production.” Tue, Aug 31, 2004 |
Beef
Characteristics (From Everhope Pinzgauers)
The Pinzgauer breed has been included in studies performed at the
USDA Meat
Animal Research Centerfor many years . These studies have shown that
Pinzgauers produce meat that is among the most tender of any beef breed and
that routinely exceeds other breeds in juiciness and flavour. Because of the
enzyme makeup of these animals, (calpains and calpastatin), the meat retains
its tenderness without the use of artificial chemical processes. The inbred
docility of the Pinzgauer also decreases the likelihood that carcasses will be
dark cutters.
As reported in the Journal of Animal Science in 1994, research showed that Pinzgauers had the highest score (5.16) for marbling among the European Continental breeds. This same report showed that although Pinzgauer had a mean marbling score similar to that of Hereford, they had 9.27% less rib fat and 7.3mm less 12th rib adjusted fat thickness. The mean shear force, as measured with the Warner-Bratzler Shear Force test, showed that Pinzgauer beef was the most tender at 4.47kg of eight other breeds tested including Angus, Hereford, Limousin and Charolais. On sensory panel scores, Pinzgauer scored highest in flavour of all breeds tested and among the highest in juiciness.
