Show-Me-Select Board Approves Genomic Testing Requirement for Natural Service Sires

Image
All bulls purchased after February 1st, 2019 for use as natural service sires in the Show-Me-Select Replacement Heifer Program™ must be DNA tested to have genomic-enhanced EPDs. All bulls used as natural service sires after February 1st, 2020 must have genomic-enhanced EPDs, regardless of when they were purchased. Seedstock producers classifying bulls as Show-Me-Select qualified in sale books must have genomic-enhanced EPDs on those lots.
Bulls purchased prior to February 1st, 2019 will be grandfathered into the program, as is the common practice with all natural service sires. However, this grandfather grace period will end February 1st, 2020. At that time for a bull to qualify for use in the program, it must have genomic-enhanced EPDs.

Why the change? The Show-Me-Select Replacement Heifer Program has the goal of producing premium heifers that perform predictably as 2 year olds. The program has a history of requiring Show-Me-Select producers to go beyond typical cattle production pr…

NCBA Cattlemen's Webinar: Winter Supplementation for Your Herd

Image
November 21, 2019 @ 7:00 p.m. CST
During winter, many cattlemen and women utilize harvested forages and even crop residues to serve as the primary diet for their cattle when most grazing forages go dormant. However, many of these feedstuffs may not meet the dietary requirements of the animal. Join Dr. Tryon Wickersham, Texas A&M; Dr. Eric Bailey, University of Missouri; and Dr. Mary Drewnoski, University of Nebraska as they cover the importance of supplementing your herd when generally lower quality feedstuffs make up a majority of the animals diet specific to regions across the U.S.

Selection for Improved Carcass in Red Angus

Image
by Ryan Boldt, Director of Breed Improvement, RAAA

Selection for carcass trait performance is important to keep in mind when making bull-purchasing decisions. Most carcass traits are moderately heritable in nature. In seedstock animals, the best method to collect information about carcass-trait performance is through the use of ultrasound imagining.

Generally, ultrasound information is collected on seedstock animals at a year of age. When an ultrasound is collected, up to four measurements are taken. The most common measurements recorded include intramuscular fat, backfat, and rib eye area which serves as the best indicators for carcass marbling score, carcass back fat and carcass ribeye area.

The ultrasound information is collected via a probe that emits high-frequency sound waves. The probe is placed on the animals back and an image is created that shows the difference between different tissues under the animal’s hide. These images are captured by a certified ultrasound technician a…

Neogen partners with IGS to enhance Igenity® Beef Profile

Neogen Corporation announced September 19th, 2019 that it has entered into a collaboration with International Genetic Solutions (IGS). The effort is focused on heightening genomic impact in the IGS platform, the only major multibreed beef genetic evaluation available, and at the same time greatly enhancing the research and development necessary to continue to improve Neogen’s Igenity® Beef Profile.

The Igenity Beef Profile is a leading global genetic testing product that helps producers of both straightbred and crossbred beef commercial cattle select their best animals for breeding programs. IGS delivers the most credible, objectively described, user-friendly and science-based genetic predictions to enhance the profitability of beef cattle producers who look to leverage the full power of expected progeny differences (EPDs).
“As part of this partnership, Neogen will benefit from access to information that will improve the Igenity Beef Profile, and IGS will endorse and promote the use of…

Great short video on the use of EPDs, including the importance of the definition of EPD.


Big shout out to Jordan Thomas for making these great videos. This one features my graduate student, Troy Rowan. Also, if you aren't following MizzouRepro on social media, you should start!

BIF 2019: Bovine Respiratory Disease (BRD) Research at US-MARC

Larry Kuehn and Tara McDaneld
U.S. Meat Animal Research Center

Bovine Respiratory Disease may be hard to diagnosis. Have to keep in mind that prey animals, like ruminants, have evolved to hide being sick.

What are the BRDC pathogens?
Bacteria

Mannheimia HaemolyticaPasteurella multocidaMycoplasma bovisOthers
Virus

Parainfluencza-3Infectious Bovine RhinotracheitisBovine Viral DiarrheaBovine Respiratory Syncytial VirusBovine Coronnavirus (implications relatively recent)

Viruses typically aren't severe on their own, but they are often the gateway for bacteria infections to start.

Difficulty of BRDC treatment records as phenotypes
Disease incidence measured as 0 or 1
Subclinicals/shedders analyzed as healthy

How do we overcome these difficulties?
Large sample sizes are needed. USDA MARC is not using a subset of USMARC Germplasm Evaluation Program. MARC is also working to improve the quality of diagnoses/necropsy. They are also looking for indicator traits. They are collecting nasal samples …
