Assessment of vitamin E and Selenium administration on udder heath and milk yield in crossbred Karan Fries cows

Abstract

The present study was conducted on 14 crossbred cows in NDRI Karnal.These14 crossbred cows were divided randomly into two groups of 7 animals each; untreated control and vitamin E and Se treatment group (5 doses of vitamin E (550 IU) and Se (15mg) administered through subcutaneously on day -30, -15, on the day of calving (day 0), day 15 and 30 of caving. CMT and electrical conductivity of milk and milk yield was monitored during postpartum period in cows. Per day milk production was increased (P<0.05) in treated group than control group. Electrical conductivity was significantly (P<0.05) higher on day 7 and day 35 in cows of control group than cows of treatment group. CMT score was observed lower in treatment group. Altogether, present study highlights the beneficial effect of administration of vitamin E and Se during peripartum period on milk yield and udder health of cross bred cows.
