Denkavit's research on long tails in piglets
Looking ahead to 2030, the European pig farming industry will undergo a significant transition: piglets with long tails will become the new standard. This change stems from stricter legislation aimed at improving animal welfare. The docking of piglets’ tails is under increasing pressure.
Tail docking is currently still advised by the international veterinary association to prevent tail biting, a behavioral problem that can lead to injuries and health issues. With the changing legislation, it is becoming increasingly important to find alternatives that ensure both animal welfare and the economic viability of the sector. Therefore, at Denkavit, we have initiated a research project on long tails.
Our Approach
At Denkavit, we aim not only to comply with future regulations but also to play an active role in developing solutions that contribute to animal welfare and the success of livestock farming. The goal of this research is to proactively support farmers in preparing for the ban on tail docking in 2030.
The project consists of several phases:
Current Status
So far, significant steps have been taken. The literature study provides insight into factors contributing to tail biting, such as genetics, barn climate, and housing. Additionally, small-scale trials with piglets with intact/long tails have started on the Pig Farm.

Future
The path to keeping piglets with long tails is challenging but not impossible. In the coming years, we will conduct further research, combining insights from literature, market information, and our own experience. Our goal is to develop effective, practical solutions that make it possible to keep piglets with long tails! We will continue to share regular updates on this topic.
