As genomic technology advances, the opportunities to address global food security and health increase. But these opportunities could be missed if steps are not taken to increase future research and extension efforts. Shrinking faculty numbers not only limit the amount of potential research, but also limit the capacity to train industry professionals about emerging genomic tools.
Concerns about a shortage of future animal geneticists were addressed during the 10th World Congress of Genetics Applied to Livestock Production by Dr. Ron Lewis during his presentation on Wednesday.
Details about proposed solutions to this shortage can be found in the related proceedings paper titled “Filling the Knowledge Gap: Integrating Quantitative Genetics and Genomics in Graduate Education and Outreach.”
As selective breeding makes cattle more productive, producers (especially dairy producers) experience a decrease in fertility. The interval between calving and first estrus is longer, conception rates from 1st insemination are lower, and the number of insemination attempts before cows are impregnated is greater. Generally, this decreased fertility is blamed on a negative energy balance, but geneticists say there may be more to the story.
During the 10th World Congress of Genetics Applied to Livestock Production, Dr. Michel Georges of University of Liege gave a presentation on Tuesday exploring an alternative/complementary hypothesis attributing the decrease in fertility to an increase in homozgosity for embryonic lethal alleles.

During the 10th World Congress of Genetics Applied to Livestock Production, Dr. Dorian Garrik of Iowa State University gave a presentation on Monday outlining a Bayesian approach combining multiple methods into a single step method.
The outlined method uses observations from both genotyped and non-genotyped animals. It does not require direct inversion of matrices and is well suited to parallel computing approaches.
More information related to this topic can be found in the proceeding titled “Bayesian Prediction Combining Genotyped and Non-Genotyped Individuals.”
