Lameness has become an increasingly important problem in cattle over the last 20 years, due to many factors including increased intensity of management, diet changes, genetics, and the emergence of new diseases.
More intense management:
Range or pastured cattle tend to have fewer foot and leg problems. Life on "slurry" covered concrete, typical of many dairy cattle management systems, predisposes their feet to both infectious and non-infectious hoof disease.
The reasons for dairy cows leaving the herd
(being culled) are:
It can be argued that lameness has a tremendous impact on both low production and reproductive failure. Low production results because a lame cow will spend more of her time lying down at the expense of time spent eating. Reproduction may be affected because a lame cow will not readily exhibit signs of estrus or maintain the proper body condition to cycle and become pregnant.
Lameness in cattle is mostly in the foot -> 90% of all bovine lameness.
