Abstract: Disclosed is apparatus and a method for detecting udder disease in dairy animals. An accelerometer is attached to each of a plurality of dairy animals. A processor determines a measure of the activity of the dairy animals to which the accelerometers are attached. Data is recorded by and automatically transmitted from a sensor unit secured to an animal, without the requirement for costly and time consuming chemical analysis of milk, or of visual or veterinary inspection of individual animals in a herd. The development of an udder disease in a dairy animal, such as mastitis, may be identified from a decrease in the monitored measure of activity of a dairy animal. A separate baseline measure of activity may be determined for each dairy animal and the ac tivity of a plurality of dairy animals in one or more herds may be taken into account, in order to reduce false positives due to external effects which are not specific to a single dairy animal.

Abstract: A method of and apparatus for grading a characteristic of an animal is described. The animal is guided to a detection area whereupon an image of the back of the animal is captured. Analysis of the image identifies anatomical points and determines angles at these points. The angles are then used to calculate a grading for a characteristic of the animal. An embodiment is presented for automating the determination of body score condition in dairy cows using seven angles determined at three anatomical points from an image over the back of the cow.
