My late spring calving season starts just before the beginning of pink eye season. In the past I've never had any pink eye problems and have given up on the vaccination 3 years ago because of the reaction you sometimes get at the vaccination site. Not long ago I bragged about not having pinkeye problems, but fate has taught me never to say never again, I've had more cases the last six weeks than I've had in the last six years together.
Over here the vaccination is an emulsion called Pilliguard Trivalent and according to the leaflet it should be given 3 - 6 weeks prior to the usuall start of pink eye season. This would be about 4 weeks before my calving season. Would this immunity be carried over to the newborn calf through the colostrum? If I were to vaccinate young calves would it have any effect or would the passive immunity from the colostrum prevent it form doing its job?
Also the instructions says to give it either subcutaneously or intra muscularly, in the past I gave it SQ and still has a few with knots in the neck from three years ago. This year I've given it IM, but the young calves walked very stiffly favouring the right front leg for about two days.(the shot was given IM in the right side of the neck as per instructions). That was two weeks ago and I haven't had any case yet and don't see any persistant reactions to the shot except for the stiffness in the calves.
Anyone with advice or experience of the same problem?
