| Popis: | The aim of the study was to analyse the relationship between the body condition and the results of metabolic profile tests done in the milk (DIM) of dairy cows in different days. Moreover, critical points in the early pre- and postpartum period were also analysed. In the experiment, blood and urine samples were taken from 1984 clinically healthy cows (from 49 large scale dairy farms in Hungary), selected randomly from various groups of cows with different physiological stage of lactation and gestation, 3-5 hours after the morning feeding. During the experiment body condition scoring (BCS) was measured on 1-5 scale, as well. It was concluded, that the BCS (body condition score) decreased from the 1st day of lactation (3.48) onwards till the 44th day (2.65) and slightly increased till the day 218 (2.89). The haemoglobin value and the glucose concentration in blood samples were ranging within the physiological range and followed the tendency of BCS and the relationship between them and DIM was (P |
