Heterosis – Ignored or Forgotten?
published: August 20th 2010 by: Dave Daley, source: California State University-Chico
So why are we still talking about heterosis? I remember attending a cattlemen’s meeting in 1967, in Bangor California when I was 9-years-old. Our farm advisor gave this very clear, simplistic report on crossbreeding-and the data was irrefutable....
Understanding EPDs
published: August 20th 2010 by: Evan Whitley source: Noble Foundation
Expected progeny differences (EPDs) are one of the most useful tools cow-calf producers have at their disposal. Their usefulness is paramount due to the importance of selecting and purchasing the right bull for commercial (and purebred) operations....
Reusable Bio-Chips Supports Cattle Genotyping
published: July 9th 2010 source: Catle Business Weekly
Fluidigm Corporation has developed the world's first reusable bio-chip architecture for the commercial market. These reusable integrated fluidic circuits (IFCs) will dramatically lower SNP genotyping costs and are designed to support accelerated sample throughput, while maintaining data quality of 99....
Crossbreeding Revisited
published: May 3rd 2010 by: Jeff Jaderborg source: University of Minnesota
Many are just finishing their calving season and will soon be changing over to breeding season mode looking to answer that question of what sire to breed my cows to this year. Well, this year I ask you to consider what heterosis could do for your operation....
Calf Quality Boosts Marketing Effort
published: March 9th 2010 by: Audry Olmstead source: NMSU News Bureau
A group of New Mexico bull producers is optimistic a new marketing program will add more value to New Mexico calves as premiums paid for calves has become increasingly competitive in the market from ranch to the retailers....
Raise The Beef You Want By Buying The Genetics You Need
published: February 27th 2010 by: Kris Ringwall, beef specialist source: BeefTalk
Time does not allow us to absorb everything in one setting. For example, it often is best to read one chapter at a time in a book so one can absorb as much as possible. Bull buying is like reading a good book....
Don’t Take Your Ultrasound Technician Off Speed Dial
published: February 9th 2010 source: Cup Lab
DNA. DNA. DNA. Everywhere you turn these days talk in the beef industry is about DNA. The Beef Improvement Federation (BIF) centered its annual convention this past summer on the role of genomics in improving selection tools....
Milk EPD And Calf Performance In Beef Cattle
published: January 28th 2010 source: Oklahoma State University Extension
In a long-term study, Oklahoma State Univ. researchers bred crossbred cows to Angus or Hereford bulls that were either very high or very low for milk expected progeny differences (EPDs). The difference in High and Low Milk EPDs for Angus sires was 27....
Financial Advantage Of Using Sexed Semen
published: January 26th 2010 source: The Cattle Business Weekly
With the help of retired Texas A&M University Economist, Dr. Jim McGrann, Sexing Technologies (ST) is now offering an Economic Decision Aid for cattle producers interested in using sexed semen. This decision aid is the first of its kind in evaluating the expected return on investment that cattle producers could see when utilizing sexed semen in their AI programs....
Pfizer To Release Genomic Test For 50,000 Markers
published: December 17th 2009 by: John A. Lacko source: Kalamazoo Gazette
Pfizer Animal Genetics will launch in January a new genomic test that is expected to greatly expand the way cattle are evaluated — increasing the chances for ranchers and others to improve the quality and value of beef that is ultimately produced....
Ultrasound Still Important Tool

DNA. DNA. DNA. Everywhere you turn these days talk in the beef industry is about DNA. The Beef Improvement Federation (BIF) centered its annual convention this past summer on the role of genomics in improving selection tools....
Time For Industry To Capture Direct Maternal Heterosis
published: November 27th 2009 source: High Plains Journal
Longevity, rebreeding and calf survivability are gaining importance as the nation's cow herd becomes more straightbred. That likely is because commercial cow-calf producers have forgotten or ignored hybrid vigor (heterosis)....
Understanding Production Traits And DNA Information
published: November 20th 2009 source: beefcattlesite.com
US - Bull breeders have been anxious to use gene markers to spring their breeding programs forward at a faster pace since these tools were released a few years ago. But does the technology live up to the hype it’s received? This question and topics closely tied to SNP panels will be addressed at an upcoming Iowa Beef Center seedstock conference in Ames, Iowa, on 10 December....

Cattle producers looking to purchase elite Hereford genetics have a new option for sourcing genetics. The American Hereford Association (AHA) has launched a new online auction Web site — BuyHereford....
More Traits Soon To Be Available For Genomic Predictions
published: September 21st 2009 source: Pfizer
Cattle producers will soon have access to a powerful new suite of traits from Pfizer Animal Genetics that uses significantly more information to generate genomic predictions. The result, which will lead to a set of traits that exhibit the highest level of accuracy to date, will emerge with the launch of the company’s first commercial genomic predictions based directly on the high-density BovineSNP50 chip....
Understanding Genetic Defects
published: August 31st 2009 by: Marty Ropp source: American Simmental Association
Unless you have been hiding under a rock lately,you are well aware of the publicity surrounding “new” genetic defects that are significantly affecting both the commercial cattle business and the business of several breed organizations....
