Rumen Microbiome Markers for Heritable Trait Selection in Ruminants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex relationship between rumen microbiome components and host genetics and physiology in ruminating animals is poorly understood, limiting the ability to select animals with desirable traits for improved feed efficiency and milk production.
Innovation Solution
A method is developed to analyze the microbiome of ruminating animals for the presence of heritable microorganisms, such as bacteria from the phylum Bacteroidetes and Firmicutes, to select animals with desirable traits like milk protein, dry matter intake, and feed efficiency by breeding them based on the abundance of these microorganisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional breeding methods are used to select ruminating animals for desirable traits, then breeding process is simple and well-established, but selection precision and ability to identify heritable traits is limited due to poor understanding of host-genetics-microbiome interactions
Solution Approach 1:
The patent uses microbiome composition as an intermediary marker to indirectly assess heritable traits in ruminating animals. Instead of directly measuring complex genetic traits, the method analyzes microbial communities in the rumen, which serve as a measurable proxy for host genetics and physiology. This intermediary approach enables more precise selection while avoiding the need to directly complex genetic analysis.
Solution Approach 2:
The patent replaces traditional phenotypic observation and simple genetic testing with microbiome-based selection. By substituting direct genetic measurement with microbial community analysis, the method achieves higher selection precision through biological markers that reflect host genetics, effectively replacing mechanical breeding selection with biological marker-based selection.
2Productivity
If microbiome analysis is used to identify heritable traits, then selection precision and breeding effectiveness is improved, but understanding of host-genetics-microbiome relationship is still required which currently exists
Solution Approach 1:
The patent leverages the natural microbiome present in the animal's rumen as a self-contained information source. The microbial community itself provides the selection criteria, requiring no external knowledge or intervention beyond sampling and analysis. The microbiome serves its own function as a genetic marker system, enabling breeding decisions based on naturally occurring biological indicators.
Solution Approach 2:
The method establishes a feedback loop where microbiome composition informs breeding decisions, which in turn shapes the genetic makeup of future generations and their associated microbiomes. By measuring microbial communities and using that information to guide breeding, the system creates a continuous cycle of selection and improvement, allowing breeding efficiency to increase progressively as more data accumulates.
3Productivity
If focus is placed on improving feed efficiency and milk production through breeding, then economic value and agricultural output is increased, but complex relationship between rumen microbiome components and host physiology must be understood first
Solution Approach 1:
The patent extracts the microbiome component from the complex host-genetics-microbiome system and uses it as a standalone selection criterion. By separating microbial analysis from direct genetic analysis, the method simplifies the measurement process while maintaining the ability to predict feed efficiency and milk production traits. The microbiome serves as an extractable biological marker that can be analyzed independently to inform breeding decisions.
Data Source
AI summary
A method of selecting a ruminating animal having a desirable, hereditable trait is disclosed. The method comprises analyzing in the microbiome of the animal for an amount of a hereditable microorganism which is associated with the hereditable trait, wherein the amount of the hereditable microorganism is indicative as to whether the animal has a desirable hereditable trait.
