Bovine Respiratory Disease Risk Assessment for Dairy Calves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bovine respiratory disease (BRD) in pre-weaned dairy calves remains a significant economic concern despite the availability of vaccines and antimicrobial drugs, with morbidity and mortality rates remaining static over the years, and current management practices often rely heavily on antimicrobials without considering the actual risk of disease development.
Innovation Solution
A method for determining the risk of BRD by extracting and analyzing dairy farm management practice information across categories such as basic herd risk profile, maternity pen management, colostrum management, milk feeding, vaccinations, and calf housing, assigning weighted risk scores, and calculating total risk scores to identify effective management practices that mitigate BRD risk, thereby reducing the use of antimicrobials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antimicrobial drugs are used heavily to prevent and treat BRD, then morbidity and mortality rates are reduced, but antimicrobial resistance increases and economic losses continue due to static morbidity and mortality rates over the years
Solution Approach 1:
The patent changes the parameter from blanket antimicrobial administration to risk-based targeted administration. By calculating BRD risk scores based on multiple management practice categories (herd risk profile, maternity pen management, colostrum management, milk feeding, vaccinations, calf housing), the system transforms the approach from high-dose universal prevention to precise, individualized intervention only when risk thresholds are exceeded, thereby reducing overall antimicrobial usage and resistance pressure while maintaining prevention effectiveness
Solution Approach 2:
The system enables farms to self-assess their BRD risk by extracting and analyzing their own management practice information. The risk calculation tool allows farms to independently identify areas needing improvement and make data-driven decisions about antimicrobial usage, reducing reliance on empirical broad-spectrum treatment protocols
2Ease of operation
If current management practices rely heavily on antimicrobials, then BRD symptoms are treated, but the actual risk of disease development is not considered and economic losses persist
Solution Approach 1:
The patent implements a feedback mechanism where management practice information is continuously extracted, analyzed, and converted into actionable risk scores. The system provides feedback to farmers about their specific risk levels in different categories (herd profile, maternity pen, colostrum, milk feeding, vaccinations, housing), enabling them to adjust practices proactively rather than reactively treating symptoms with antimicrobials
Solution Approach 2:
The system performs preliminary risk assessment before BRD develops by analyzing management practices that precede disease onset. By evaluating factors like colostrum quality, housing conditions, and vaccination status beforehand, the system enables preventive actions to be taken before disease occurs, rather than waiting for symptoms to appear
3Quantity of substance
If vaccines and antimicrobial drugs are made available, then prevention and treatment options exist, but morbidity and mortality rates have remained static over the years
Solution Approach 1:
The patent applies local quality by tailoring prevention strategies to each farm's specific risk profile rather than using uniform approaches. The system identifies which specific management categories (e.g., colostrum management, housing, vaccinations) pose the greatest risk to each farm and recommends targeted improvements in those specific areas, maximizing the effectiveness of available preventive measures for each local context

AI summary
Provided are methods of determining the risk of bovine respiratory disease (BRD) in pre-weaned dairy calves on a dairy farm. In certain aspects, the methods include extracting dairy farm management practice information from a dairy farm, wherein the dairy farm management practice information comprises one or more items of information for two or more dairy farm management practice categories selected from the group consisting of: basic herd risk profile, maternity pen management, colostrum management, milk feeding, vaccinations, and calf housing. In certain aspects, the methods further include assigning weighted risk scores to the items of dairy farm management practice information extracted, and determining a total risk score for each of the two or more dairy farm management practice categories based on the assigned weighted risk scores. Also provided are non-transitory computer-readable media and computer devices that find use, e.g., in practicing the methods of the present disclosure.
