PROBLEM TO BE SOLVED: To provide a conveyance belt for a rat-proof poultry house, which can effectively prevent damage of gnawing by a rat.SOLUTION: A whole surface of a base belt 7 is coated with a synthetic resin composition 8 in which rat repellent is mixed. Density of the rat repellent in both side parts 9, 9 of the base belt 7 is set to be higher than density of the rat repellent in an intermediate part 10 of the base belt 7. The base belt 7 is made of a band-like knitted cloth made by Russell-knitting synthetic fibers, and looks like a net having square meshes. Warp yarns 12 in both side parts 9, 9 are arranged to be closer than that of the intermediate part 10. As the rat repellent, natural capsaicin or synthetic capsaicin are suitably used. A mixed amount of the capsaicin to the synthetic resin composition is set to be 1-10 mass%. |
