Abstract

Vaccination is one of the major stress factors that affects the semen productivity of the breeding bulls who showed consistent higher body temperature for several days. Therefore, a study was planned to assess the ameliorative strategy of vaccination stress by Vitamin E supplementation on twelve Holstein-Friesian crossbred bulls (432 ejaculates) maintained at Artificial Breeding Research Centre, ICAR-National Dairy Research Institute, Karnal. The bulls were vaccinated for FMD @ 3 ml by SC injections. In treatment group (6 bulls), Vitamin E was supplemented @ 4000 I.U./bull/day, ten weeks before and nine weeks after vaccination and another group without Vitamin E supplementation served as control. Vitamin E supplementation resulted in significantly reduced sperm abnormalities and improved sperm concentration, total motile spermatozoa (106), total live spermatozoa per ml (106), total sperm (106), live sperm/ml and total dose harvested in treated group as compared to control. Individual motility (%), mass motility, NEC (%), HOST (%) and IA (%) were higher in the treatment group, but it was not significant. Better blood biochemical profile of bull was evident in Vitamin E supplemented group though it was not significant statistically. It can be concluded that Vitamin E supplementation in vaccinated bulls was effective in ameliorating vaccination stress to some extent.
