Mould-resisting automatic ingesting groove

Provided is a mould-resisting automatic ingesting groove. During pig feeding through a traditional pig feeding trough, a large pig can eat as much as possible, a small pig cannot be fed enough, and accordingly the difference of the body sizes of pigs in the same pigsty becomes larger and larger. In recent years, in pig raising production, producers pay more and more attention on prevention and control over mould, and mycotoxin in traditional fodder can severely damage the health of animals and threaten human food safety and health at the same time. The mould-resisting automatic ingesting groove comprises a fodder trough (1). A base (5) is arranged in the fodder trough (1). The base is connected with a mould-resisting layer (4) which penetrates through a hopper (3) and the base and is communicated with the fodder trough. The hopper is fixed through a support (2) which is connected with the fodder trough. A gap is formed between the base and the fodder trough. A gap is formed between the outer wall of the mould
