Correct Answers for Lecture 16
Ethical considerations include balancing animal welfare with the benefits for management, such as reducing injuries and aggression. Trade-offs depend on the procedure, its necessity, and availability of less painful alternatives.
Alternatives include environmental enrichment, lower stocking densities, and genetic selection for non-aggressive lines. Implementation challenges include cost and space requirements.
Indicators of pain include decreased suckling behavior, stiffness, and vocalizations. These behaviors show significant distress and support the need for analgesic use.

Analgesics can reduce acute pain but are sometimes cost-prohibitive. Barriers include availability, administration challenges, and varying regulations across regions.
