In light of the rising popularity of probiotics and to prevent bogus products being marketed as beneficial, the EU has introduced a complicated system regarding probiotics. The end result is that a probiotic must be tested and have demonstrated safety and efficacy (ie that it works) in the group in which it is being used.
Our original AVIPRO PLUS was developed and worked across the species range, but no single organism is licensed for this purpose any longer. So AVIPRO PLUS will be changing into a prebiotic based blend of electrolytes, glucose and vitamins and will retain its cross-species use.
For the bird owner we have developed AVIPRO AVIAN which is based on the old AVIPRO PLUS but now contains an organism licensed in birds so it can be used for everything from canaries and macaws to ducks and chickens.
For the rabbit owner, there is a choice of two products containing rabbit licensed organisms. We have ProC the high vitamin C, green chlorophyll containing probiotic for routine use in small furries. Early in 2013 we also introduced a product we had been working on for about 2 years previously, ProC Professional, a vet only (and the Vetark website).
IS USING THE 'WRONG' PROBIOTIC DANGEROUS?
Absolutely NOT, the organisms are all safe and in many cases efficacious across the species barriers. The licensing choices are commercial decisions about which agricultural market to go for, not a scientific choice of which group it will work best in.
For many years ProC was used in rabbits and birds. We cannot make any claims about ProC in birds, it does not have a license for use in birds and we would always recommend (because the EU licensing process says that we must!) that owners use the product licensed and demonstrated in the animal.
There are special issues regarding dogs. One company has patented the inclusion of probiotics in dog food, because of this other companies are avoiding licensing their organisms for dogs since the patent blocks this route to market. Hence prebiotics such as AVIPRO PLUS are widely used, we know that rabbit products are also commonly used but can't encourage this.
