What is a mating system?

• A. A method to predict feed efficiency
• B. The genetic evaluation method
• C. The number of offspring per sire
• D. Deciding which animals are mated to each other

Answer: (D)

A mating system is the planned arrangement of pairings among animals to achieve breeding goals. It’s about deciding which individuals are matched with which partners to shape genetic gain, manage inbreeding, and preserve genetic diversity over generations. By choosing how to mate—whether to combine high-producing animals with complementary mates, use rotational or reciprocal crosses, or apply controlled inbreeding—the program influences how traits are passed on and how closely related the offspring will be. This is distinct from predicting feed efficiency, which is about evaluating performance or predictability rather than how matings are arranged. It’s also not a genetic evaluation method, which focuses on estimating an animal’s genetic merit. And while the number of offspring per sire can be affected by the mating plan, that outcome is a result of the system, not the definition of the system itself. So, the essence of a mating system is the deliberate decision of which animals are mated to each other to steer the genetic trajectory of the herd.
