Abstract ▼ AI-Helper

This study was conducted to demonstrate the prevalence of subclinical ketosis in dairy cattle based on days in milk and herd level. Four to five blood samples were collected in five different lactation periods and analyzed for ${\beta}$-hydroxybutyrate using a Portable Ketone Test Kit. Subclinical ketosis was observed in 12 herds at prevalence of 6.3~57.1% depending on herd level, with four herds showing more than 40% subclinical ketosis prevalence. The distribution of subclinical ketosis in the early lactation period, high yield lactation period, mid lactation period, late lactation period and dry period was 9.5%, 27.5%, 36.8%, 27.9% and 12.5%, respectively. Clinical ketosis was only observed during early lactation (9.5%) and mid lactation (2%) period.

문제 정의

This is the first population-based study of the prevalence of SCK in this region. The goal of this study was to investigate the prevalence of SCK in dairy cattle based on days in milk (DIM) and herd level at Chungnam province.

성능/효과

The results indicated that Herd-level prevalence of SCK ranged from 0 to 57.1%. Additionally, 0 to 60% SCK prevalence was observed at the herd level at 7∼12 days after calving, while 0 to 24.
In conclusion, this is a population-based report of the prevalence of SCK in Chungnam dairy herds. The results of this study inform dairy herd owners and their advisors that SCK is more prevalent in most of the herd and its frequency is vary from one herd to another herd. This might be presuming due to the differences in feed management on each farm and breeding for high milk production.

후속연구

This might be presuming due to the differences in feed management on each farm and breeding for high milk production. The results of this study were based on a cross sectional study; therefore, further studies will be needed to determine the longitudinal changes of BHBA and cow herd level feeding management.
