BHB Evaluation for Subclinical Ketosis Prediction
The first objective of this study was to investigate the relationship between concentrations of beta-hydroxybutyrate (BHBA) in milk and blood to assess the reliability of the BHBA concentrations in milk measured by a semi quantitative keto-test paper to detect subclinical ketosis (SCK) in 50 fresh high-producing Iranian Holstein cows in Golestan Province, Iran. The second objective was the effects of SCK on milk yield and components.

Ketosis Prevalence and Correlation in Iran
Ketosis is a metabolic disorder which usually occurs in cows during1 early lactation in both, industrialized and developing countries. There are no data available about the prevalence of ketosis in major dairy producing provinces in Iran. This study investigated the prevalence of ketosis among 1,002 Iranian Holstein cows from days 5 to 50 post calving in various parity and lactation stages in 13 regions of Iran.
Incidence of Subclinical Ketosis in Dairy Cows with Factors
Subclinical ketosis is one of the most prevalent metabolic disorders that usually occurs in cows during the first weeks of lactation. This study investigated the relationship between energy level, body condition score and silage butyric acid with incidence of subclinical ketosis (SCK) in dairy cows during the first month of postpartum. Fifty healthy pregnant Holstein cows from 10 commercial dairy farms were studied.
