Learn how to locomotion score dairy cows for lameness. You can locomotion score using a 3, 4, or 5 category scale.
All three systems provide pictures, video and verbal descriptions of each category. A numerical and graphic summary of cows scored is provided.
This summary may be emailed via pdf.

  • Score by pen or herd
  • Select categories to score – 3, 4, or 5
  • Pictures and videos of example cows
  • Bar chart analysis



To begin scoring animals, you must enter the number of animals contained within the pen. It may be helpful to identify the pen if you plan to do more than one.

The picture examples along the right hand side of the screen may be switched between Standing and Walking by touching the Switch Pictures button at the top of the screen. For training purposes these pictures may be replaced with videos by touching the Training Videos button near the bottom of the screen.

As you score lame animals the count and percentage will be indicated in the text boxes below the scoring buttons. Normal cows are not scored. If an animal is scored in the wrong category, touch the switch at the bottom to OFF and touch the same score button to subtract. Touch the switch at the bottom of the screen to ON and resume scoring.

Summary information is presented when the Summary button is touched. This information can be emailed by pressing the Email icon in the upper right hand corner of the Summary screen. Press Done to return. To clear the scored results, press the Clear Scores button. All scores will be deleted and the app will be ready to start again.

To change scoring systems touch the Score System button.

Walks without obvious gait asymmetry or weight transfer between limbs and cannot discern which leg is lame after a few strides. Steps may be slightly uneven and may have a flat or subtle arch to the back.

1 Walks with even weight bearing and rhythm on all four feet, with a flat back.
Long fluid strides possible.
1 Stands and walks normally with a level back. Makes long confident strides.
2 Steps uneven or strides shortened, but affected limb or limbs not immediately identifiable. 2 Stands with flat back, but arches when walk. Gait is slightly abnormal.
2 Asymmetric gait with obvious weight transfer and shortening of the stride of the affected limb altering cadence of movement. May also show a head bob, back arch and joint stiffness leading to abduction of the limb. 3 Uneven weight bearing on a limb is immediately identifiable and/or obviously shortened strides (usually with an arch to the center of the back). 3 Stands and walks with an arched back and short strides with one or more legs. Slight sinking of the dew-claws in limb opposite to the affected limb may be evident.
3 Able to walk only with difficulty, almost unable to bear weight on the affected limb. Pronounced back arch with rear limb lameness. These animals are frequently in poor body condition and in obvious pain. 4 Unable to walk as fast as a brisk human pace coupled with uneven weight bearing and shortened stride, with a back arch. 4 Arched back standing and walking. Favoring one or more limbs but can still bear some weight on them. Sinking of the dew-claws is evident in the limb opposite to the affected limb.
5 Pronounced arching of the back. Reluctance to move, with almost complete weight transfer off the affected limb.
