Risk factors associated with tail damage in New Zealand dairy cattle

Area of Science:

• Veterinary Science
• Animal Welfare
• Dairy Farming Practices

Background:

• Tail damage in dairy cattle is a growing welfare issue.
• Limited research exists on the risk factors contributing to tail damage prevalence.
• Understanding these factors is crucial for improving dairy cow welfare.

Purpose of the Study:

• To identify risk factors associated with tail damage in New Zealand dairy cattle.
• To analyze the relationship between farm management practices and tail damage.
• To provide evidence-based recommendations for reducing tail injuries.

Main Methods:

• A study involving 200 New Zealand dairy farms.
• Prevalence assessment of tail damage (deviated or injured tails).
• Survey of farm management and handling practices, with statistical analysis of 42 variables.

Main Results:

• Median herd-level tail damage prevalence was 11.5%.
• Increased tail damage odds were associated with higher milking frequency (always twice daily).
• Reduced tail damage odds were linked to the use of coaxing (gentle persuasion) for moving cows.

Conclusions:

• Poor handling and infrastructure interaction are likely causes of tail damage.
• Milking frequency and handling methods are significant modifiable risk factors.
• Further international research and standardized tail scoring are needed.
