What would an individual rabbit be termed if it primarily produces offspring?

The term used to describe an individual rabbit that primarily produces offspring is "breeder." A breeder is specifically recognized for their role in the reproduction of rabbits, focusing on genetic traits, lineage, and the quality of the offspring. This term indicates that the rabbit is part of a program or has a purpose associated with producing young rabbits, whether for specific qualities, show purposes, or other breeding goals.

In contrast, "producer" could refer to a broader concept that may include multiple species in an agricultural context and is not specific to breeding rabbits. "Show rabbit" suggests a rabbit that is primarily raised and trained for competition based on appearance and defined breed standards, while "pet rabbit" refers to rabbits kept primarily for companionship rather than for breeding purposes. Therefore, "breeder" distinctly identifies the focus on offspring production, making it the correct choice in this context.
