Description

technical field [0001] The invention belongs to the technical field of dairy cow production, and relates to a dairy cow self-adaptive multifunctional bust measurement device and a system thereof. Background technique [0002] During the growth process of dairy cows, behaviors such as feeding, drinking, rumination, excretion, exploration, and stress run through the entire process, and can reflect different stages and different physiological states in the growth and development process. These behaviors, in turn, can appear as normal behavior or abnormal behavior. Among them, normal behavior is the reflection of heredity, instinct and acquired environment adaptation, and it is the performance of dairy cows' self-maintenance and healthy growth; while abnormal behavior is usually contrary to its performance when receiving bad stimuli or living in harsh conditions. Biologically learned behaviors and events, such as morbid behavior and stress behavior, are an important manifestati...

Problems solved by technology

However, at present, a soft tape is generally used for measurement. Because the cow’s bust is large, it needs the assistance of others to measure. One person will bypass the soft tape around the cow’s bust and grasp the two ends of the soft tape. One person cannot complete it independently.

In addition, a large number of existing dairy farms generally wear studs on the ears of each cow and wear a cow number plate with a unique identification to distinguish the cows. The cow number plate has a single function and has certain defects such as irreversible trauma to the cow’s ears.
