Development and External Validation of a Predictive Model of Severe Neonatal Calf Diarrhea in Hanwoo Calves Using Animal, Environmental, and Management Risk Factors.

ABSTRACT:

Background

Neonatal calf diarrhea accounts for most pre-weaned calf losses in Hanwoo cattle. A novel predictive model of severe neonatal calf diarrhea will help veterinarians and farmers prevent disease in calves.

Hypothesis/objectives

Development and external validation of a simple predictive model for severe neonatal calf diarrhea in Hanwoo cattle.

Animals

Hanwoo calves were used to develop the model (n = 3179) and for its external validation (n = 1383).

Methods

Retrospective, observational study. The predictive model was developed using logistic regression analysis with data from Hanwoo calves from 2019 to 2022. The model was externally validated using data from Hanwoo calves in 2018 and 2023.

Results

After univariable and multivariable logistic analy
