Why is lameness a critical factor in dairy cattle evaluation?

Lameness is a critical factor in dairy cattle evaluation because it can significantly impact the animal's mobility and feeding ability. Cows that are affected by lameness typically experience pain, which can lead to decreased mobility. This reduced mobility affects their ability to access feed and water effectively, leading to lower feed intake. When a cow cannot move comfortably, it may avoid standing or walking to the feeding area, which can further compromise its nutrition and overall health.

Moreover, lameness can indirectly influence various areas such as milk production, reproductive performance, and overall herd welfare. Healthy, mobile cows can graze better and utilize feed more efficiently, resulting in better milk output. Evaluating lameness, therefore, is essential for assessing the overall productivity and well-being of dairy cattle, making it a key component in dairy cattle evaluations.
