Abstract: Provided is a new method of measuring an amount of movement of an animal. A measurement value of an animal as a measuring target is sequentially measured with a scale (21), an amount of change in the measurement value obtained in chronological order is calculated, and from division of the amount of change in the measurement value by a weight of the animal, an amount of movement of the animal is measured. Accordingly, weight differences between individual living bodies and in the process of breeding are eliminated, and an amount of movement of an animal based on changes in the weight of the living body can be measured.
