Final answer:
A two-breed rotation with a terminal sire crossbreeding system, also known as a Rota terminal system, is a breeding system commonly used in livestock production. It involves rotating two different breeds of livestock in successive generations and crossbreeding them with a specific breed known as the terminal sire.
Step-by-step explanation:
A two-breed rotation with a terminal sire crossbreeding system, also known as a Rota terminal system, is a breeding system commonly used in livestock production. In this system, two different breeds of livestock are rotated in successive generations, with one breed used as the parent generation and the other as the sire. The offspring of each generation are then crossbred with a specific breed known as the terminal sire, which is chosen for its desirable traits such as high growth rate or meat quality. This system allows for the production of hybrid offspring with superior traits while maintaining genetic diversity.
