چکیده
Calf diseases remain a challenge for dairy producers from both an economic and welfare perspective. Genetically selecting disease resistance in calves is promising approach that could contribute to sustainable farming. Genetic evaluations, however, require well-defined consistently recorded phenotypes be successful. Therefore, this study aimed understand the current state of calf recording on Ontario farms. records respiratory illness diarrhea were available national milk organization (Lactanet Canada, Guelph, Ontario, Canada) 2009 2020. A case was conducted describe diagnoses practices by surveying subset 13 producers. The percentage farms increased 2.6% 11.1% Potential sources data loss identified along information chain farm genetic evaluation database. Clear definitions thresholds diagnose disease, standard operating procedures recording, as well transfer pipeline, which includes exchange formats, are needed facilitate inclusion health traits evaluations.
