Physiological and behavioural sensor-captured data from cow under subacute ruminal acidosis compared to cows under control conditions

This dataset contains 8 files containing all data from an in vivo experiment on dairy Cows conducted in March to May 2015 in an INRAE experimental facility named Herbipôle. The objective of the study was to determine whether early sensor-captured modifications in dairy cow behaviour can indicate risk for SARA (Sub-Acute Rumen Acidosis), independently of the diet. We analyzed modifications in ruminal pH, rumen concentrations of fatty acids, milk production and milk fat-to-protein ratio to identify SARA status, and modifications in cow activity captured by a real-time locating system to identify changes in behaviour related to SARA in cows fed a moderately high-energy (31.5% starch) or a low-energy diet (10.5% starch). Control cows (n=14) received the low-starch diet for 60 days. Challenge cows (n=14) received the same low-starch diet except for 10 days when they were gradually switched from the low- to the high-starch diet and the next 14 days when they were fed the high-starch diet only. Dataset1 presents individual rumen fermentative parameters Dataset2 presents individual milk yield and milk quality parameters Dataset3 presents individual cow rumen pH daily indicators obtained through a ruminal bolus. Dataset4 presents individual cow activities inferred from the realtime localisation system. Dataset5 presents individual cow ingestion data Dataset6 presents daily individual cow risk to develop SARA Dataset7 presents raw rumen pH data for challenge cows Dataset8 presents raw rumen pH data for control cows
