NB – Old Thread – please excuse me resurrecting an old thread. 
I have just started making kefir and wondered if it would be good for my rabbit.
I found the following info:
“I have had great luck recently feeding a capful of goat kefir to a sick animal. It seemed to really give a big boost to his immune system. It contains lots of bacteria which is good for the digestive system. Goat kefir is easier to digest then cow kefir. Have some yourself while you are at it…it’s good for critters….
Bunnies on antibiotics also need to have live yogurt or acidofolus or probiotics or kefir. My vet says the bunnies like yogurt but I have never had one who would eat it voluntarily. Soak a bit of granola in it and let it dry or wipe some on their paw. Once I mixed it with the pellets slurry and forcefed it. I have had good luck with goat kefir.“

But I alo read: “Yogurt or dairy products should never be fed to rabbits, for the following reasons:
Lactobacillus/Acidobacillus are not a natural host of the adult rabbit intestinal and, if surviving the passage through the acid stomach, it will not survive the anaerobic conditions of the cecum.
The lack of adhesive capability may further prevent Lactobacilli from colonizing in the intestinal tract.
Adult rabbits naturally do not have the right bacteria to digest milk derivates in the cecum and intestine.
In the absence of those Lactobacteria, milk derivates accelerate the onset of stasis in adult rabbits.“

Then confuses me by then going on to say:
“Yogurt diluted in water can nevertheless help rabbit suffering from intestinal bacterial disturbances et diarrhea, by protecting the endemic bacterial flora and allowing it to grow.”
Also: “Yogurt or acidophilus are strongly recommended when your rabbit is receiving any type of antibiotic to keep normal gut flora.”

I will look into this again – no rush.
We do use Protexin Fibreplex for Rabbits (she loves it so I pretend it’s a reward/treat) and Protexin Pro-Fibre for rabbits: “contains high levels of insoluble and soluble fibre, probiotics to help re-populate the gut with beneficial microorganisms and Preplex – a prebiotic to stimulate the growth of the good bacteria.” http://www.animeddirect.co.uk/small-animals/digestion
This is a great website and forum, but I am such a slow and clumsy poster.
