Production, physiological (HRV) and behavioral data (locomotion scores) of dairy cows

The attached Excel datasheet contains a comprehensive database with 4,467 measurement records representing physiological and production data collected from dairy cattle at 25 different time points between March and May 2024. During data collection, detailed heart rate variability (HRV) parameters were measured under different activity levels and behavioral states.

The database contains 32 different parameters, including basic animal identification data (ear tag number, lactation number), production indicators (milk yield: mean 36.6 kg, range 8.6-57.2 kg), health indicators (lameness scoring on 1-4 scale, body condition score mean 3.0), and detailed physiological measurements. Heart rate parameters include basic pulse rate (mean 78.4 beats/min, range 53-117), mean and standard deviation of RR intervals (776 ms), and specialized HRV indicators: RMSSD (mean 12.7 ms), pNN50, frequency-domain parameters (VLF, LF, HF spectral components), and non-linear indices (SD1, SD2, LF/HF ratio mean 9.0).

A unique characteristic of the data collection is the detailed documentation of behavioral context in 77 different event categories, including feeding phases (Feeding 1-5), standing and lying positions, ruminating activity, and other behavioral states. This enables analysis of HRV parameters according to specific activity levels and behavioral patterns. The milking system type (6 different codes) was also recorded, which is particularly valuable for examining technological effects on heart rate variability.

The project and data collection were implemented within the framework of the consortium application numbered GINOP_PLUSZ-2.1.1-21-2022-00164, entitled "Climate change-integrated, data-driven cattle diagnostic decision support system," with the collaboration of Béke Agrár Ltd. and the Hungarian University of Agriculture and Life Sciences. The project implementation start date: April 1, 2022. The planned physical completion date of the project: March 23, 2025.
