PROBLEM TO BE SOLVED: To provide a pet food structurally designed to have a dental care function.SOLUTION: The pet food 10 having a prescribed length and is formed into a columnar or stick-like shape is formed as follows: a plurality of through holes 12 each composed of a string-like long hollow space continuously extending in a longitudinal direction are internally formed and the through holes 12 are open at both ends thereof respectively. An excellent toothbrushing effect is obtained when a pet chew the pet food (when the teeth of the pet get into the through holes 12, or the pet food 10 is broken, cut off or cut into strings owing to chewing) because the end parts, the cut-off ends, and/or broken pieces of the pet food 10 rub up the surfaces of the teeth of the pet, repeatedly hit the surfaces of the teeth of the pet every time when chewed, and get in and out of so-called periodontal pockets to have a higher possibility to clean (scrape out) food particles.COPYRIGHT: (C)2012,JPO&INPIT【課題】構造的な工夫を加えることによりデンタルケア機能を付与してなるペットフードを提供する。【解決手段】所定長さを有し、柱状あるいは棒状の形状をなすペットフード10であって、内部に、長手方向に連続的に延びる紐長い中空空間からなる貫通孔12の複数本が設けられ、該貫通孔12が両端において開口してなるペットフード10。【効果】ペットが噛んだ際(噛むことで貫通孔12に歯が入り込んだり、あるいはペットフード10が破断されたり、切断されたり、紐切れになった際)に、ペットフード10の端部や切れ端、破片がペットの歯の表面を擦り、噛むごとに繰り返し当たったり、いわゆる歯周ポケットに出入りして食べかすを掃除する(かき出す)可能性が高くなり、優れた歯みがき効果が得られる。【選択図】図1
