Abstract: Efficient estrus identification is an important way to improve the fertility of heifers and enhance the economic efficiency of cattle farms. With the increasing scale of dairy farming, the traditional manual observation of estrus identification method has been difficult to adapt to the needs of estrus identification of dairy cows in large-scale farms. Pedometer estrus identification is difficult to detect quiet estrus and does not improve estrus detection rates. Although the body temperature parameters of estrus identification potential, but the cow body hair, body surface temperature measurement is not ideal, and contact temperature measurement collection site is limited, wearable equipment research and development difficulties, different parts of the collection of cattle body temperature data vary greatly. For this reason, this paper summarizes the results of the previous use of different parts of the cow′s body temperature data estrus identification, comparative analysis of the relationship between the pattern of change of the body temperature of each part of the cow in estrus and estrus, for the research and development of efficient cow estrus identification technology to provide scientific reference.

Key words: cows, body temperature in different parts, estrus
