ANIMAL MANAGEMENT
Pre-lamb vaccinating your ewes Lambs are born with very few antibodies and rely on the ewe’s colostrum for protection against clostridial diseases including pulpy kidney and tetanus. Clostridial vaccination of the ewe just prior to lambing is utilised on most New Zealand farms to boost the level of antibodies lambs receive in colostrum. The more antibodies they receive, the higher their chances of survival if they face disease challenge. It is therefore vital to get pre-lamb vaccination right – both with the timing and the level of antibodies produced. For timing it’s about stimulating the ewe at the right time, so her antibody levels peak when forming her colostrum. Ideally this is about 2 weeks ahead of lambing, but different farms have different management systems and lambing spread varies so the flexibility to vaccinate earlier can be important. For antibody levels, it’s about ensuring sufficient antibodies are available for transfer into the lamb. How much is sufficient can vary, depending on whether a ewe has one, two or three lambs suckling and how much disease-challenge a lamb may face. The gut of the newborn lamb is best at absorbing these antibodies within the first 12 hours of life, so it’s crucial this

However, if your flock has a higher number of multiple bearing ewes or you vaccinate earlier (for example, to reduce the likelihood of sleepy sickness), or you want longer protection of lambs to reduce losses through until weaning, then NILVAX® would be a much better choice for your farm. NILVAX is the specialist prelamb vaccine, formulated with a powerful 5 in 1 plus an
Whether NILVAX or MULTINE is the right choice for your farm is up to you. Both are developed and manufactured in New Zealand to the highest standard, for New Zealand farming challenges. They both have excellent local field data, showing that NILVAX produces the highest antibody levels in ewes at pre-lamb, and MULTINE also produces high antibody levels2.
