Protein profile in dairy cows with left displaced abomasum
The goal of this study was to compare and evaluate the protein profiles of healthy cows and cows diagnosed with left displaced abomasum (LDA) (at the first phase of lactation). Cows were admitted to the Clinic of Ruminants, University of Veterinary Medicine and Pharmacy in Košice, Slovakia (UVMP) between 2018 and 2020. Blood samples were collected from the jugular vein to an EDTA tube from 26 cows, 13 healthy ones and 13 diagnosed with LDA. Biochemical indices were determined in a UVMP laboratory and included total protein, albumin, creatinine, urea and total immunoglobulins. Statistical analysis was performed using GraphPad Prism 9.0.0 and two-tailed Student’s t-test. The mean value of total protein was 75.38 ± 14.93 g/l, and 77.84 ± 10.97 g/l for control group and for LDA affected cows, respectively. The mean albumin concentration for the control group was 37.27 ± 6.02 g/l, while for LDA group it was 32.84 ± 8.7 g/l. The mean creatinine and urea concentrations were 99.72 ± 66.88 µmol/l and 4.44 ± 4.47 mmol/l, respectively, in the control group, and 91.67 ± 25.44 µmol/l and 5.09 ± 2.65 mmol/l, respectively, in cows diagnosed with LDA. Total immunoglobulins were at the level of 37.13 ± 7.65 zinc sulphate turbidity test (ZST) in healthy cows whereas LDA group had 32.8 ± 5.2 ZST. Although the difference was not significant (P > 0.05), protein profiles varied between healthy cows and cows diagnosed with LDA. Further research is needed to determine the differences in protein profiles between groups of larger numbers of individuals.
