Where are we going with genomics and genetic improvement?

published: June 5th 2017 by: Matt Spangler/Alison Van Eenennaam source: BIF 2017

Where are we going with genomics and genetic improvement     Early DNA tests with one or two markers had little predictive ability. As tests improved, more markers were added. Eventually there was a switch to genomic predictions....

As DNA tests become more common, researchers rapidly add equipment to keep up

published: April 25th 2017 by: Kathleen Phillips source: Texas Agrilife Today

(Editors: April 25 is National DNA Day commemorating the day in 1953 when scientists published papers in the journal Nature on the structure of DNA. Now, 64 years later, the concept is much more familiar to the average person....

Can you compare EPDs across breeds?

published: February 3rd 2017 by: Matt Spangler/Larry Kuehn source: University of Nebraska Extension

Expected Progeny Differences published by one breed are inherently not comparable to those published by another breed. This is due to several factors including differences in arbitrary base adjustments used by each breed, the lack of data from comparisons among animals of different breeds, and differences in selection emphasis for a specific trait in one breed compared to another....

Hair shedding scores: A tool to select heat tolerant cattle

published: January 31st 2017 by: James E. Decker and Jane Parish source: University of Missouri and Mississippi State University

Hair shedding scores are an easy and effective way to measure cattle’s ability to cope with heat stress. In this fact sheet, learn the how, when, and why of hair shedding scores. Responsible beef breeding requires matching cattle genetics to production environment....

New cost - effective DNA test available to beef seedstock industry

published: October 17th 2016 source: Neogen GeneSeek

Description of a Simbrah

published: August 26th 2016 source: American Simmental Association

Simbrah is a composite breed. Animals containing 5/8 Simmental blood and 3/8 Brahman or Zebu blood are designated as purebred. A sixteenth of other breeds is allowed making it easy to incorporate traits, such as polled or other characteristics, for specific purposes into the purebred....

Gene editing research increases

published: June 20th 2016 source: Genus

British animal genetics firm Genus is diving deeper into the hot area of gene editing, in a move Chief Executive Karim Bitar says will bring long-term gains at the cost of a hefty hike in research spending....

Zoetis and Angus compete world’s largest genomic calibration for GE-EPDs

published: May 19th 2016 source: Zoetis

Zoetis and Angus Genetics Inc. (AGI) announced the completion of the world’s largest and most comprehensive genomic calibration for beef cattle and associated integration into genomic-enhanced expected progeny differences (GE-EPDs)....

Economically Relevant Traits and Selection Indices

published: May 16th 2016 by: By Matt Spangler, source: NE Extension Beef Genetics Specialist

Sire selection does not need to be overwhelming or complex. Centuries of work by geneticists and statisticians have allowed for the development of tools that help producers make decisions relative to the next bull you purchase; do not ignore them....

New GeneSTAR test from Zoetis identifies polled genotypes

published: March 9th 2016 source: Zoetis

Commercial beef producers have long-established breeding programs that propagate polled animals.  Now, by using a new genomic test called GeneSTAR Horn/Polled available from Zoetis, beef producers can identify homozygous and heterozygous polled for Brahman, Brangus, Limousin, and Simmental at an early age....

Across Breed EPD Adjustments

published: February 15th 2016 by: By Matt Spangler, NE Extension Beef Gene source: University of Nebraska Extension

  Expected Progeny Differences published by one breed are inherently not comparable to those published by another breed. This is due to several factors including differences in arbitrary base adjustments used by each breed and differences in selection intensity for a specific trait in one breed compared to another....

How To Valuabull

published: February 4th 2016 by: Aaron Berger source: University of Nebraska Extension

The spring bull sale season is underway. Catalogs are being studied, EPDs and individual animal performance numbers are being compared and choices are being made as to which bulls will be the next herd sires....

Visit Your Breed Association Website for Maternal Breed Indexes

published: January 15th 2016 by: Kris Ringwall source: North Dakota State University

Hidden treasures for beef producers are the various breed association websites, which are the doorway to better understanding the performance of the cattle available within each breed. One fairly new addition to sire summaries is a selection index, available from several breed associations....
