The study aimed to investigate whether the rumen wall thickness (RWT) follows with the data from the collar sensor system and how deeply it depends on feeding management used in the high-yielding dairy cow farm, as well as what benefit it could bring to diagnose subacute rumen acidosis (SARA) in cows. The data obtained from the collar sensors about chewing activity were analysed in relation to milk recording results, the rumen wall thickness (RWT) and the context of the composition of feed easily digestible carbohydrate changes during the intensive lactation phase. The dynamic of RWT was evaluated concerning milk amount and quality, its relation to fertility, and the size of the cows, which were taken into account. The results showed that the sensor system provides information about cow behaviour but does not provide direct information about the SARA problem in the herd. The RWT was related to the changes in feed easily digestible carbohydrate content and chewing activity. In conclusion, the sensor system allows monitoring of feed ingestion, but overall data about productivity and milk composition are necessary to make conclusions and induce ideas about corrections. Additional RWT measures are necessary to monitor rumen health and SARA presence timely, so monitoring the RWT may lead to a longer productive life for the cow.
