Tail shortening of cattle
Policy type: Policy
Date ratified: 1 October 2011
The New Zealand Veterinary Association (NZVA) is opposed to the shortening of cattle tails except for veterinary medical reasons.
The Animal Welfare (Painful Husbandry Procedures) Code of Welfare 2005 limits tail shortening in cattle to the last two or three vertebrae of the tail. The NZVA policy on bovine tail shortening of cattle is in line with its policy (3b) that opposes physical alterations to the natural state of animals unless they are demonstrably necessary for the welfare of the animals concerned.
The practice of docking the tails of dairy cows was originally adopted to reduce contamination of both milking staff and cow udders. However, subsequent studies (Matthews et al 1995) found that leptospirosis and mastitis levels were no different in docked and undocked cows. The 2005 code has allowed switch removal “to improve comfort for milking personnel and enhance milking efficiency”, but recommends that alternative solutions are tried first. The NZVA is of the opinion that non-surgical alternatives are available in the form of regular cleaning and trimming of the hair in those few cows where this is a problem, especially now that automated tail trimmers are available.
