Final answer:
When choosing to add or subtract animals from your background production system, it is important to consider functionality and productivity rather than just appearance. Good strategies include weeding out poor breeds, selecting animals that will be ready at the same time, and choosing from a uniform herd with animals having similar traits.
Step-by-step explanation:
When choosing to add or subtract animals from your background production system, picking animals with narrow frames for appearance's sake is NOT a good strategy. It is important to consider the functionality and productivity of animals rather than just their appearance. Narrow frames may not necessarily indicate good health or efficiency in production.
On the other hand, it is a good strategy to:
- Weed out the poor breeds: Eliminating breeds that do not perform well or meet the desired production standards helps maintain a high-quality herd.
- Select animals that will be ready at the same time: This ensures efficient management practices, such as synchronization of breeding and feeding programs.
- Choose from a uniform herd with animals having similar traits: A uniform herd allows for consistency in production and management practices.
