| Outline of Final Research Achievements |
In dairy cattle subclinical ketosis (SCK) is closely linked to milk productivity during early lactation period. We investigated about SCK prevalence in 2,593 dairy cattle fed in Hokkaido from April 2012 to March 2015.
The prevalence in early lactation was 17.4% overall and included regional difference. Half of all SCK was type II SCK that is known to have severe process (others: type I). It was shown that type II SCK already fell into negative energy balance including insulin resistance around 2 to 3 weeks before calving. Therefore, it is considered that adequate management for dairy cattle around one month before calving is essential to the SCK prevention.
