According to the FDA, which of the following is a minor species?

• A. Turkey
• B. Sheep
• C. Pig
• D. Goat

Answer: (B)

In FDA regulatory practice, animals are grouped as major or minor species for veterinary product oversight. Major species are the ones produced in the largest numbers and with the most established regulatory pathways—commonly cattle, swine, chickens, and turkeys. A minor species refers to any other animal outside that big four. Sheep fits this category, since it isn’t one of the major four. This classification matters because minor species often involve different regulatory considerations and may be eligible for incentives under programs designed to encourage product development for less common species. The other animals listed are typically associated with the major category (turkey and pig), while goat is also generally considered minor in many FDA contexts; the key takeaway is that sheep is categorized as a minor species.
