Evaluation of risk factors of omphalitis in newborn beef calves with indoor housing
Background
Omphalitis is the third most common cause for diseases and infections in newborn calves. Its risk factors are well described in dairy production, but data in beef production is limited.
Objective
To identify and quantify the risk factors of omphalitis in cow-calf operations with seasonal indoor calving period.
Animals
Nine hundred sixty-four calves included from 22 cow–calf operations in central France were included.
Methods
A prospective cohort study involved data collection during two visits for each calf. Simple and multivariable logistic regression analyses evaluated the association between omphalitis and the variables.
Results
Among 964 included calves, 311 (32.3%) calves had an omphalitis. Accounting for farms’ random effect, risk factors for omphalitis highlighted by the univariable analysis were: absence of navel disinfection (odds ratio (OR) = 2.3, [1.45–3.04]), wetness of bedding calving area (OR = 1.8–2.1, [0.78–2.83]-[0.63–3.57]), cleanliness of calves’ pen (OR =1.6–2.8, [1.22–2.27]-[2.02–3.84]), wetness of calves’ pen bedding (OR = 1.7–3.2, [1.12–2.06]-[3.08–3.84]), calf weight at birth >50 kg (OR = 2.0–5.0, [1.02–2.38]-[1.51–11.1]), umbilical cord length <3 cm (OR = 2.2–2.3, [1.53–3.11]-[1.24–4.38]), and sex (male vs female) (OR = 2.6, [2.08–3.69]). The multivariable analysis, accounting for farms’ random effect, showed that the absence of navel disinfection (OR= 2.2, [1.44–3.09]), wetness of bedding calving area (OR = 1.9–2.4, [0.55–2.83]-[0.59–3.28]), calf weight at birth >50 kg (OR = 1.9–2.6, [1.03–2.56]-[1.43–12.5]) and sex (male vs female) (OR =2.4, [2.09–3.49]) were risk factors for omphalitis.
Conclusions and clinical importance
These observations may help identify animals at early risk (>50 kg, male, short umbilical cord) and pay particular attention to the wetness of bedding and cleanliness of housing. This study highlights the importance of calving-pen bedding, calf characteristics and navel disinfection.

Preventive Veterinary Medicine is one of the leading international resources for scientific reports on animal health programs and preventive veterinary medicine. The journal follows the guidelines for standardizing and strengthening the reporting of biomedical research which are available from the CONSORT, MOOSE, PRISMA, REFLECT, STARD, and STROBE statements. The journal focuses on:
Epidemiology of health events relevant to domestic and wild animals;
Economic impacts of epidemic and endemic animal and zoonotic diseases;
Latest methods and approaches in veterinary epidemiology;
Disease and infection control or eradication measures;
The "One Health" concept and the relationships between veterinary medicine, human health, animal-production systems, and the environment;
Development of new techniques in surveillance systems and diagnosis;
Evaluation and control of diseases in animal populations.
