Abstract:
Provided is a technology that allows easy evaluation of a degree of growth of pigs raised in a group instead of guiding the pigs one by one to a cage. A growth evaluation device includes an extraction unit that extracts, from an image captured by a camera disposed to face a pen in which the plurality of pigs are raised in the group, a buttock image having buttocks of one of the pigs facing forward, an arithmetic unit that arithmetically determines a buttock width from the buttock image, and an evaluation unit that evaluates the degree of growth of all the plurality of pigs on the basis of a prescribed number or more of the buttock widths arithmetically determined by the arithmetic unit.
