Malondialdehyde (MDA) level and protein profile of serum after calving towards the provision of selenium-vitamin Etm on dairy cow frisian holstein (FH)

Abstract

This study aims to determine effectiveness of Selenium and vitamin Etm intramuscularly to the serum MDA level and protein profile after calving. Twenty pregnant FH cows were use in this experiment, divided into four groups. The control group (K0), Group 1 (K1) : 0.5 mg / ml Selenium + 50 mg vitamin Etm, Group 2 (K2) : 1.5 mg / ml Selenium + 50 mg vitamin Etm and Group 3 (K3) : 2 mg / ml Selenium + 100 mg vitamin Etm. Selenium-vitamin Etm given intramuscularly at the age of 7 and 8 months of pregnancy, two weeks before birth, 7 and 14 days after calving. Measurement of serum MDA levels and protein profile were carried out on 25 and 45 days after calving. Serum MDA levels on the 25 days after calving very varied results in each treatment group, while serum MDA levels decreased with increasing doses of Selenium and vitamin Etm on the 45 days after calving. There was no difference in serum protein profile in all of treatment groups. This study concludes that administration of selenium-vitamin Etm at a dose of 2 mg/ml Selenium + 100 mg/ml of vitamin Etm can reduce serum MDA levels.
