Broken Tail 


Broken tails can result from improper handling. Breaks often are present near the base of the tail due to extreme force when applying a tail twist or jack for restraint. They can also appear mid-length or at the tip of the tail due to bending the tail over other structures in an attempt to restrain the cow.

​This instructional video by the University of Saskatchewan demonstrates the proper way to apply a tail twist.

​Which cows to assess:

  • Lactating cows
  • Heifers
  • Hospital cows

If this is a follow-up evaluation and broken tails were previously found, look for evidence of new or recently broken tails in the first lactation heifer pen.
​
​The number to assess in each group is determined by the sample size calculator.

How to assess:

  • Count and record the % of animals with broken tails as evidenced by:
    • Tail appears abnormally shaped or asymmetrical
    • Vertebrae may be misaligned
    • Swelling, abrasions, crusted blood around the broken vertebrae, or a necrosed tail tip (in recently broken tails)
