INVESTIGATION OF THE PREVALENCE OF KETOSIS IN COWS IN ARDAHAN REGION IN TURKEY

Abstract

In the postpartum period, the energy requirement increases in high yielding dairy cows. According to the negative energy balance (NED) degree, clinical or subclinical ketosis may occur during this period. In this study; The aim was to investigate the prevalence of ketosis in dairy cows in Ardahan Region. The animal material to be used in the study was determined as 200 as a result of statistical analyzes of TUIK data. Animal material was selected from Ardahan city center, Göle, Çıldır, Hanak and Damal districts. The enterprises where, study is carried out are similar in terms of milk yield, management, maintenance and nutrition factors. Blood samples were collected on days 7 and 14 postpartum to determine the prevalence of ketosis. Beta hydroxybutyrate (BHB), non-esterified fatty acid (NEFA) and glucose levels were determined from the obtained samples. Patients with BHB concentration with 1.0<1.4 mmol / L were considered to have subclinical ketosis. Patients with BHB concentration with ≥1.4 mmol / L were considered to have clinical ketosis. The prevalence of clinical ketosis in the postpartum period in Ardahan was 1% (2/200) and the prevalence of subclinical ketosis in Ardahan was 10% (20/200). Blood glucose levels of animals with ketosis were significantly lower than the healthy animals.
