Objective of this study was to determine the prevalence of some metabolic disturbances including negative energy balance (NEB), subacute ruminal acidosis (SARA), low serum urea nitrogen (SUN) and high SUN, and to investigate the risk factor involving with these metabolic disturbances. The study was conducted with cross-sectional study in early lactation cows during 3-5 weeks post calving in 35 farms (320 cows). The prevalence of NEB, SARA, low SUN and high SUN were 15.9 percent, 22.3 percent, 36.9 percent and 14.0 percent respectively. The linear association between serum beta-hydroxybutyrate (SBHB) and ruminal pH was found significantly (p LT 0.05). The main risk factors of SARA include younger cow, low SBHB cow, cow fed with corn tip and corn husk. The risk for NEB are high ruminal pH cow, high body condition score (BCS) cow before calving, low BCS cow at sampling time, cow fed by low concentrate amount per time and the preventive factors for NEB are cow fed by more times of concentrate and cow fed with roughage chopping. Adding extra protein source can reduce low SUN while feeding cow by lower percentage of protein in concentrate can reduce the high SUN. Feeding cow by commercial concentrate is the high risk for high SUN. The suitable management should be advised the farmer to improve dairy cow health in small dairy holder farm.
