The percentage of internal steatosis in dairy cattle older than 1 year, submitted for pathology to GD, is still high and continues to increase. As of 2018, the pathologists have seen a considerable increase in internal steatosis in dairy cattle older than 1 year. This is an undesirable development, as internal steatosis impacts the health of cattle.

A pilot study conducted in 2019 showed internal steatosis to be associated with fatty liver and abnormal uteri, and it would seem to be more prevalent in cows during the first stage of gestation. This quarter, the development of internal steatosis has been broken down into age groups. The
increase is seen in all age groups, whereby it is striking that the prevalence of internal steatosis is also increasing in animals in the rearing period (aged 1-2 years). GD is therefore once again requesting attention for this signal and has made a proposal for further research in order to gain insight into the background behind the development of internal steatosis.
