New tools equal new opportunities for the swine industry

New genomic tools, including a draft sequence of the pig genome and high density SNP chips, allow swine researchers opportunities to better understand the biology of the pig and limiting production traits.

Dr. Max Rothschild of Iowa State University explored applications of SNP technologies during a presentation at the 10th World Congress of Genetics Applied to Livestock Production.

Potential applications of the new technology include: Read more

On the road to recovery

The decrease in dairy cow fertility which began in the 1980s now appears to be on the mend.

In a presentation given during the 10th World Congress of Genetics Applied to Livestock Production, Dr. Jennie Pryce of La Trobe University spoke about the latest phenotypic and genetic trends related to female fertility in international Holstein populations. 

The improvements are slight, with some fertility characteristics (such as calving interval) merely plateauing instead of improving. Read about the latest fertility trends in the proceedings paper titled “World Trends in Dairy Cow Fertility.”

Genomics gets fishy

Breakthroughs in the Atlantic salmon genome project, initiated in 2010, now allows Atlantic salmon researchers access to technology comparable to the technological advancements of the major livestock species.

During the 10th World Congress of Genetics Applied to Livestock Production, Dr. Thomas Moen of AquaGen gave a presentation on Tuesday describing the new technologies available, including:

  • a high-quality genome reference
  • a SNP-chip containing more than 657k polymorphic SNPs
  • A SNP-chip containing 132k polymorphic SNP and a linkage map

Details about the new genomic technology emerging from the Atlantic salmon genome project and related studies can be found in the proceeding paper titled “Genomics in Selective Breeding of Atlantic Salmon.”

The big questions: Possible limitations of genomic information

During the 10th World Congress of Genetics Applied to Livestock Production, Dr. Brian Kinghorn of  the University of New England gave a presentation on Monday about the potential impact genomic information could have on genetic change.

The presentation addressed 4 major questions about what genomic information can reveal. Read more

Public comments to FAA needed to maintain research with drones

By Deb Hamernik and Penny Riggs, ASAS Public Policy Committee

DroneUnmanned aerial systems (UAS), also known as drones or “unmanned aerial vehicles” (UAV) have received much publicity in recent years and have even been called by some as “the next big thing for agriculture.” Advocates suggest that as farms get larger in size and have fewer employees, UAS may be useful to scan large pastures for sick or injured cattle, or survey fields for plant health or soil and water conditions. UAS may also be used to ward off birds from crops, pollinate trees, monitor the snow pack, or forecast water supplies. More and better information may allow farmers and ranchers to make better management decisions and enhance the efficiency of food production. In practice, UAS have not yet been proven as cost effective alternatives to existing agricultural practices, but interest in testing the potential application of UAS on the farm remains high across the country.

ASAS looking for 2015 Science Policy Interns

Now that the Fall semester is underway on most college campuses, it is time for undergraduate and graduate students to start planning for Summer 2015.

ASAS is pleased to announce that applications are due October 27, 2014 for the 2015 ASAS Science Policy Summer Internship program.

The program is made possible thanks to the generous support of the ASAS Foundation through the Appreciation Clubs for Bob Zimbelman, Harold Hafs, Jack Britt, Barb Glenn, and Louis Boyd.

Each intern will receive a total of $3,500 for the 60-90 day internship during the academic summer session in 2015. Read more »

Senate releases draft of America COMPETES Reauthorization Act

by Penny Riggs / ASAS Public Policy Committee

CapitolThe Senate version of the America COMPETES Reauthorization Act of 2014 (S2757) was introduced on July 31. The bill would increase budgets for the National Science Foundation and the National Institute of Standards and Technology over the next five years. The bill also promotes participation in STEM fields, as well as research efforts at agencies including NASA and NOAA.

On July 22 the House passed portions of the hotly debated Frontiers in Innovation, Research, Science and Technology (FIRST) Act (HR 4186; previously described in Taking Stock), and the America COMPETES Reauthorization Act of 2014 (HR 4159). Read more »
