The microbiome significantly impacts animal traits. Including the host and its microbiome (holobiont) in genetic models can speed up improvements in farmed animals by considering host genome effects on microbiome-linked traits.
Area of Science:
- Animal genetics and microbiology
- Host-microbiome interactions
- Genomic prediction modeling
Background:
- The microbiome plays a crucial role in host phenotypic variation.
- Genomic prediction models are vital for genetic improvements in livestock.
- Understanding the holobiont is key to unlocking full genetic potential.
Purpose of the Study:
- To explore the integration of microbiome data into genomic prediction models for farmed animals.
- To investigate how host genome influences microbiome-mediated phenotypes.
- To enhance genetic gain by accounting for host-microbiome interactions.
Main Methods:
- Developing genomic prediction models that incorporate microbiome information.
- Analyzing the indirect genetic effects of the host on microbiome composition and function.
- Evaluating the impact of holobiont-informed models on predicting animal performance.
Main Results:
- Genomic models incorporating holobiont data show potential for accelerated genetic gains.
- Host genetics significantly influence microbiome-associated traits.
- Accounting for indirect genetic effects is crucial for accurate prediction.
Conclusions:
- Integrating microbiome data into genomic prediction models offers a promising avenue for livestock breeding.
- Holobiont genomics can lead to more effective genetic selection strategies.
- Future research should focus on refining models to capture complex host-microbiome interactions.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
