Abstract
A total of 22 subclinical ketotic and 18 healthy cows were studied to evaluate changes in various metabolic parameters. Blood samples were collected thrice from each cow. In comparison to control cows a significant decrease was seen in haemoglobin, packed cell volume, total erythrocyte count and glucose, (lower than the normal range), and significant increase in beta hydroxyl butyric acid BHBA (>1.2 mmol/l) and non esterefied fatty acid NEFA (>0.4 mmol/l) indicating subclinical ketosis, where as non significant difference was recorded in all other parameters in sub clinical ketotic cows. Oxidative stress parameters evaluation revealed a significant increase in LPO levels, while a significant decrease was recorded in SOD and GSH levels in subclinical ketotic cows in comparison to the control cows. A significant decrease in body condition score and in milk yield was recorded in SCK cows in comparison to control cows.

Key words: Body condition scoring;BHBA;Hematolobiochemical;Minerals;NEFA;Oxidative stress
