Condition score 9: The cavity around the tail head is not visible and folded fatty tissue is clearly visible around the tail head area. It is difficult to feel the pelvic bone although possible with very firm pressure. The ends of the tranverse processes cannot be felt anymore. The cavity between the backbone and tranverse processes is filled up with fatty tissues and may even have a bulging appearance. In closing Body condition scoring can be used as a tool to evaluate the feeding programme on a dairy farm. It is generally accepted that the body condition of cows at calving affects the milk yield and reproductive performance of cows in the subsequent lactation period. Scoring cows should therefore be part of the feeding management of a dairy herd. It needs to be done regularly to correct the feeding programme of cows in the different stages of the lactation period. The body condition of cows is scored at the tail head and loin area separately after which it is combined in a final score. The tail head area is used as the reference score with the score in the loin area confirming or adapting the final tail head score. There are currently a number of different body condition scoring systems each with its own definitions indicating scores. It is therefore important when discussing condition scores with feed company representatives and the herd veterinarian that the same system is being used by different people. Some systems use half scores while others use full scores. A condition score of 3.0 to 3.5 is similar to a score of 5 to 6 on another scoring system. The accuracy of body condition scoring can be improved by using the camera technology at the same time as cows being weighed on a walk-over scale.
