Abstract

The aims of this study were to determine the nutritional status of Holstein cows by ultrasound measurement as well as the average depth of subcutaneous fat corresponding with BCS evaluation. A total of 981 ultrasound measurements and visual body condition scores were used. BCS assessment was performed on a 5 point scale with 0.25 point increments. Subcutaneous fat was measured in the pelvic area dorsally of the hip joint using the apparatus SonoVet 2000, linear probe (L2-5/170CD) with the frequency of 5.5 MHz.
