Hi Guys,
Thought I would add my two cents worth here. Like so many things, yogurt can be given in small amounts. Not the best of ideas and we don't offer it to anyof our buns due to the lactose concern...but a small amount should not hurt. The idea behind yogurt had always been to "add" bacteria back into the gut. Problem is...the bacteria in yogurt is not the same strain as found in a rabbit's gut. It has aways been assumed that lactobacillus acidophilus has been the right replacement. It's not...but it does work by acidifying the gut and making a more favorable environment for beneficial bacteria to grow. There are much better ways to do this. Critical Care has it....and you can buy a non-dairy powder from heath food stores. The really good bacteria that is needed is lactobacillus casei. I do use some of the supplements to control the pH conversion process in weaning cottontails....basically I control the acidic conversion.
Many, including vets, offer advice like yogurt and Karo syrup (yikes!!) because it is still in many of the manuals they use that are so woefully out of date. Sorta like some of "grandma's" home remedies....usually ineffective so the best you could hope for is that is would cause no harm. Yogurt is not something wewould use here.
