What are two management practices that can enhance product safety?

The selection of correct injection techniques and observance of withdrawal times is essential for enhancing product safety in swine management. Correct injection techniques ensure that vaccines and medications are delivered precisely and safely, minimizing the risk of injury or infection at the injection site. This ensures the health of the animal and the safety of the product that comes from it.

Observance of withdrawal times is equally critical because it ensures that any medications administered to the animals are completely out of their systems before they are processed for food. This practice prevents residues from entering the food supply, thereby protecting consumer health and maintaining product safety standards.

While the other options mention important management practices, they do not directly address the critical aspects of product safety in the same specific way as the chosen answer. For instance, regular feeding schedules can help ensure proper growth and health but do not inherently address product safety as clearly as managing injections and adhering to withdrawal times.
