Just curious, why would anyone use Lambivac in preference to Heptavac P Plus? They seem similar except that Heptavac covers more diseases.
Not trying to start a row here, genuinely curious.
Goats don't respond that well to these clostridial disease vaccines, so it is thought that if you vaccinate against fewer diseases that you get a better immune response to the ones that you have vaccinated for, and therefore better protection. As you rightly Lambivac is similar but Heptavac covers more diseases, so fine in sheep that we know do respond well to these vaccines but not so good in goats.
Also there is no point vaccinating for diseases that are unlikely to be a problem and for our goats the extra diseases that Heptavac has in it, are usually far less of a problem in goats than they are in sheep.
So it would seem that using Lambivac will give better protection against those diseases that matter most. I hope that helps answer your question Rosemary.
I suspect that the thinking on the best vaccine to use has changed over the years as more evidence becomes available.
