PROBLEM TO BE SOLVED: To provide an estrus notification system capable of notifying a user of estrus of a cow to be detected distinctively from disease based on a vagina temperature of the cow.SOLUTION: An estrus notification system includes: a normal temperature confirmation means (S2) for confirming a temperature of a vagina A of a cow to be a normal temperature which is 37.0°C<A<39.5°C; a moving average means (S4, B) for calculating the moving average of a vagina temperature of each cow for four hours which is confirmed the normal temperature by the normal temperature confirmation means based on the ID; a memory means for storing the moving average B calculated by the moving average means and reading the data after 24 h (S5, C) and reading the data after 48 h (S6, D); an estrus detection means (S7) for detecting the cow which is in an estrus condition when the formula satisfies the relation: B≥C+0.4°C and B≥D+0.4°C; and a transmission module for transmitting the ID and the occurrence of the cow in the estrus condition detected by the estrus detection means. |
