Genomics Update – The Background of Information Release

Thursday, November 6th, 2008

Update from The Centennial Celebration of the Animal Improvement Programs Laboratory (AIPL) – Oct. 28, 2008 – Baltimore, MD
By David Selner

The Animal Improvement Program Laboratory (AIPL) recently celebrated their 100th anniversary of helping United States dairy producers. At the general session of this event, scientists presented the research data that describes how genomic information can be utilized to increase the accuracy and the reliability of current genetic evaluations. Genomic research by the USDA laboratory has been ongoing for many years, but was only made possible by the cooperation of the major National Association of Animal Breeders members and Semex, who are Cooperative Dairy DNA Repository (CDDR) Contributors.

Questions have been raised as to who has access to this research data and over what time period. At this meeting, USDA scientists explained the specifics behind this research project. In the early 1980s breeding companies were approached to provide straws of semen from popular sires and all young sire progeny test sires. All of the major companies did provide this DNA material to create the DNA library at no cost to USDA. Genomic research continued through the 1980s and 1990s but no substantial marketable products were developed during this time frame. In the last few years the development of more sophisticated equipment and techniques to examine DNA in greater detail has allowed more progress. Suddenly the research became more focused on increasing genetic merit predictions with gene level data.

To avoid getting risky experimental data out in the public domain, and yet to help determine if this experimental data was truly useful a limited amount of information was shared with industry experts from the original CDDR collaborators. To formalize this process, an agreement was developed to further fund more research at USDA by the original collaborators. More DNA material and funding was provided by CDDR members and USDA granted exclusive access (one of USDA’s technology transfer mechanisms) to receive male genetic predictions during a five-year research period. USDA scientists justified this action by explaining all of the time, money and DNA material that had been provided over the last 20 years with no expectations from the original collaborators. In addition this research is still ongoing and will take several more years to complete. Even today with the January public release of genomic enhanced genetic evaluations, more research is being done to refine techniques and provide greater accuracy and reliability.

Segments of the industry, not CDDR contributors, have asked for clarification on this agreement. USDA’s simple answer was to cover the initial investment of the cooperators, to allow further investigation without misleading the whole breeding industry and to allow a reasonable transition phase into a different method of evaluating dairy genetics. No intent to slight certain segments of the industry or put them at a disadvantage was ever implied.

All genomic data completed in this first phase of research on currently marketable sires will be provided to the public in January 2009. Additional research is ongoing and will take time. The final timeline is to release all of the research genomic data on all sires in the DNA library in the spring of 2014. The genomic evaluations on females tested in approved laboratories and submitted to USDA will be made public in January 2009 by the respective breed associations as part of their normal products and services.

The concerns of some people about secrecy and exclusivity appear to be overly sensitive to their real importance. It appears to be a function of timing of the experimental data, its limited release to gain invaluable data to confirm research results and the fact that the research is still ongoing. No intent was made to keep people uninformed. Rest assured that by 2014, everyone will have access to hopefully the most accurate system of genetic evaluation in the world.

Good people = good reproduction

Thursday, February 7th, 2008

Dr. Ray Nebel has been visiting with DairyLine Radio over the past few weeks about things that can derail a herd`s reproductive success. To recap, the things he has touched on so far are:
-Transition
-Nutrition
-Disease
-Lack of systems

But the constant behind all of these things is people! Working with good people translates into a good team that will work hard to make things better. They are the ones working with the transition cows, mixing the ration, treating sick cows, etc. There must be strong compliance to set protocals and communicaton within the team. Schedule monthly team meetings as a time to have question & answer for everyone on the team.

Diseases effecting reproduction

Friday, January 25th, 2008

In DairyLine`s continuing segment on what will derail reproduction in a herd, Dr. Ray Nebel of Select Sires cites disease as the third most important. Proper transition cow management and nutrition were the first two areas producers should be concerned with.

In regards to disease, the big three that you should screen for are BVD, Neospora & Leptospirosis. BVD is a disease that can mutate easily so you need to be vigilant in your testing, which can be done with a milk sample. Neospora can result in abortion in the second trimester and testing should be performed on the aborted fetus to see if that was the cause. Lepto results in lower conception rates and can be screened for with a urine sample. Work closely with your vet to stay on top of prevention of these 3 diseases that can cause problems with your herd`s reproductive health.

Nutrition and reproductive health

Thursday, January 17th, 2008

Dr. Ray Nebel of Select Sires shares important nutrition elements all producers should be aware of and continue to monitor in order to ensure a reproductively healthy herd.

1. Dry Matter Intake
2. Bunk Management
3. Energy Density
4. Protein Type & Level
5. Minerals
6. Toxins

Utilize the expertise and experience of your nutritionist. Make sure to make daily “walk throughs” a part of your routine – too much or too little feed, clean water, comfort of cows. Also, monitor the Milk Urea Nitrogren (MUN) of the herd as it is an indicator of nitrogen not utlized by the cow.

Proper care for transition cows

Friday, January 11th, 2008

Knowing and being able to recognize the warning signs that might derail reproduction is very important. In the weeks ahead DairyLine Radio and Dr. Ray Nebel of Select Sires will be visiting about this topic. To start this series, Thursday`s Reproductive Moment focused on proper care of transition cows.

The transition period is the most important time in a cow`s reproductive cycle. Proper care during this time is the key to getting off to a good start as the cow enters the milking herd. The primary concerns are problems calving, metritis, metabolic disorders and excessive weight loss. Close monitoring of close-up cows (2-3 weeks prior to calving) is important. Of special concern is overcrowding.

Reproductive Moment…the problem cows

Friday, January 4th, 2008

Dr. Ray Nebel shares information in Thursdays Reproductive Moment regarding identifying your herds early problem cows. The entire DairyLine Radio segment can be heard by clicking the play button below. Here are a few of his key points.

It used to be that in order to identify problem cows in the herd, the only tool dairy producers needed was “cow sense.” This ability to recognize and understand when cows are uncomfortable or just arent doing their best, is becoming more and more of a lost art. Instead, dairies have come to rely on tools such as internal body temperature monitors and locomotion scoring. By identifying the problem cows early on, producers will avoid investing the time, money and labor to get her pregnant.

Breeding Strategies

Thursday, December 20th, 2007

Our Thursday Reproductive Moment on DairyLine Radio features a conversation with Dr. Ray Nebel of Select Sires. The topic today focuses on the next step after an early pregnancy test.

Current statistics tell us that approximately 60-65% of the cows bred on first service will remain open. To increase the chances of settling on the second service, a couple of different strategies are recommended:
1. Give GnRH one week before the early pregnancy exam. Upon being found open at the exam, prostaglandin is then administered followed by the final GnRH injection 2 days later. Breeding is recommended 16 hours later, in other words, 3 days after they were found open on exam.
2. If declared open on the early pregnancy exam date, begin the Ovsynch program. GnRH injection followed by prostaglandin 7 days later, GnRH 2 days later and then breed 16 hours later. This results in breeding 10 days after they were found open on exam.
