Abstract:

This study aimed at evaluating the relationships between postpartum VKS and colostral IgG, lipid metabolism, liver functions and oxidative stress parameters in dairy cows with body conditioning scores (VKS) ≤3.5 and >3.5. The study included 60 milk cows of the same race, who had two or more births in a milk farming, aged 3-5 years. The VKS changes of cows were observed to be <0.5 from the dry period to the frozen period. In the 24 hours after birth, the average VKS level for 30 inches was 3.24±0.24 and the average serum β-hydroxibothyric acid (BHBA level was 0.36±0.07). In the 24 hours after birth, the average VKS level for 30 wheels with VKS >3.5 was 3.96±0.14 and the average serum BHBA level was 0.38±0.07. The VKS is 3. Compared to the indicated values in cows with 5; in cows with VKS ≤3.5, the levels of serum non-ester fatty acid (NEFA), high-intensity lipoprotein (HDL), paraoxanase-1 (PON-1) and malondaldehyde (MDA) were significantly lower, and the levels of triglyceride, albumin, SOD and colostral IgG were significantly higher. As a result, to ensure better lipid metabolism and oxidative stress management and higher colostral IgG levels in dairy cows, it was proven that VKS changes in cows were beneficial for the period from dry period to birth <0.5 and postpartum VKS ≤3.5.
