Hereford and Red Angus Heifers Recruited for Genomics Research

The University of Missouri is recruiting 2,500 Hereford heifers and 2,500 Red Angus heifers to participate in a heifer puberty and fertility genomic research project. Heifers should be registered Hereford, registered Red Angus, or commercial Hereford or Red Angus. Hereford x Red Angus crossbred heifers targeted for the Premium Red Baldy Program would also be a good fit for the research project. Producers must be willing to work with a trained veterinarian to collect the following data: ReproductiveTract Scores collected at a pre-breeding exam 30 to 45 days prior to the start of the breeding season. PelvicMeasurements (height and width) collected at the same pre-breeding exam 30 to 45 days prior to the start of the breeding season. Pregnancy Determination Using Ultrasound reporting fetal age in days. Ultrasound will need to occur no later than 90 days after the start of the breeding season. In addition, heifers must have known birth dates and have weights recorded eithe

Sustainability: What is it and why does it matter?

Dr. Sara Place
Oklahoma State University

Took human civilization from 10,000 BC to 1804 AD to reach a billion people. We are now projected to reach 9 billion people by 2045. Human population growth is exponential.

Sustainability is a "wicked" problem. Such a problem has the essential characteristics that it is not solvable, thus it can only be managed. There is no clear definition of the problem, different stakeholders have different definitions, and the beef production system is very complex.

Place's working definition entails economic, environmental, and social solutions to create to sustainability.
Most of the pressure has come from environmental groups. The biggest concern is global warming. Climate has fluctuated over time. The problem is that carbon dioxide levels are increasing more rapidly than before. Previous high was 300 parts per million, but we are now over 400 parts per million.

Why are animal rights and environmental groups focusing on beef production? Movies like Cowspiracy get their statistics from the UN's Livestock's Long Shadow report. The land use change used in the life cycle analysis refers to desertification and deforestation linked to cattle production. These land use changes are happening in developing world, like South America and southeast Asia. Thus, a third of the report does not apply to U.S. beef production. To address these points, a report titled "Clearing the Air: Livestock’s Contribution to Climate Change" addressed these concerns. Livestock's Long Shadow is a global assessment and should not be applied regionally. In the U.S. 3.65 of greenhouse gas emissions come from livestock. Most importantly, transportation industry was not evaluated using a life cycle analysis. The new UN FAO report shows that cattle production using modern practices has a smaller environmental footprint.

Less than 1% of solar energy is used by photosynthesis. Cellulose is the most abundant organic compound on the planets. Cattle are basically bioreactors that allow humans to utilize cellulose. Without cattle, this would not currently be possible. Today we produce the same amount of beef with 30% fewer animals. The beef industry is using 33% less land.

Food insecurity was the spark of the Arab Spring. Food insecurity in the U.S. is defined as not knowing from where your next meal will come.

Public perception of intensive systems is not positive. But, the public is favorable of pastoral cow-calf production. This is more than just an "educate the public" issue. There are differences in values and trust. We need to close the communication gap between public, research, and food industry.
