New research updates on rabbit nutrition New research updates on rabbit nutrition; it's okay to question your vet (and your doctor, for that matter). Most textbooks are between 5 and 15 years out of date, and some curriculum is over 30 years past. Often, you will get more updated information from farmers and breeders who are actively seeking the most cutting-edge care for their animals. The health of your animals (and yourself) should be a conversation, not a dictation. It is perfectly fine to do independent research.
