Lameness in dairy cattle is a significant issue, impacting not only the health and welfare of cows but also carrying substantial economic consequences for the dairy industry.
The term ‘lameness’ broadly refers to any deviation from a cow’s normal gait and movement patterns. These deviations may be due to painful issues, such as a hoof lesion, or result from non-painful factors, like altered gait in cows with large udders. Environmental influences, such as navigating slippery surfaces, can also temporarily affect a cow’s gait.
However, the focus of ‘lameness’ is primarily on conditions that cause pain or discomfort, leading to restricted mobility in cows. Lameness can manifest in varying degrees, from a mild limp to severe impairment. In the dairy industry, several locomotion scoring systems have been developed and implemented, varying from simple binary classifications (lame vs. non-lame) to more nuanced multiple-point scales, with some systems employing up to a 9-point scale. These scoring systems are utilized both on farms, as part of regular assessments to monitor the overall health status of the herd and identify individual lame animals, and in research settings to study lameness more systematically.
How prevalent is lameness in dairy farming? A recent review study, which compiles data from various studies worldwide over the past three decades, indicates an average lameness prevalence of 23%. This means that, on average, one out of every four cows is lame. Such a significant percentage underscores the importance of our discussion and the urgent need to address this issue in the industry.
However, it’s notable that farmers often report a lower incidence, indicating that many cases go unnoticed. Survey studies suggest that farmers are aware of only about one third of the lameness cases in their herds, possibly due to challenges in detecting these conditions.
