Question 1

What are the main routes for administering compounds to rabbits in research?

Accepted Answer

Compounds can be administered to rabbits through oral, intranasal, or gavage routes depending on study objectives and desired pharmacokinetic profiles. Oral administration delivers compounds through food, drinking water, or syringe feeding. Intranasal administration targets the nasal mucosa, while oral gavage provides precise stomach delivery. Each route offers different advantages for systemic or localized delivery.

Question 2

How should you calculate and prepare compound dosages before administering them to rabbits?

Accepted Answer

Calculate the appropriate dose based on the rabbit's body weight to ensure accurate dosing. Prepare all materials using aseptic technique to minimize contamination and maintain sterility. Proper preparation prevents infection and ensures reliable experimental outcomes. Dosage accuracy is critical for obtaining valid research results and maintaining animal safety.

Question 3

What is oral gavage and when is it used for compound administration in rabbits?

Accepted Answer

Oral gavage delivers compounds directly into the stomach using a lubricated tube attached to a syringe. This method provides precise dosing when monitoring food or water intake is unreliable. Typical gavage volumes range from 5–20 mL/kg body weight. Administer the compound slowly to minimize reflux or aspiration risk and ensure safe delivery.

Question 4

What positioning and safety precautions are necessary for intranasal compound administration in rabbits?

Accepted Answer

Position the anesthetized rabbit in dorsal recumbency with the head elevated to facilitate absorption while maintaining airway safety. Administer the compound slowly as droplets into each nasal cavity through the respective naris. Typical volumes range from 0.1–0.25 mL per nostril. Divide larger volumes into multiple aliquots administered gradually to minimize aspiration risk.

Question 5

What adverse responses should you monitor for after administering compounds to rabbits?

Accepted Answer

Observe rabbits for regurgitation, aspiration, sneezing, nasal discharge, respiratory abnormalities, or signs of discomfort following administration. Monitor animal behavior, food and water intake, and overall condition to ensure successful compound delivery and animal welfare. Early detection of adverse responses allows for timely intervention and prevents complications.

Question 6

How can you ensure a rabbit consumes the intended dose when administering compounds orally through food or water?

Accepted Answer

Monitor intake carefully when incorporating compounds into food or drinking water to verify the rabbit consumes the full intended dose. This method works best when rabbits have consistent feeding patterns. If intake monitoring is unreliable, consider alternative methods like syringe feeding or oral gavage to guarantee accurate dosing and study validity.

Question 7

What ethical guidelines and principles must be followed when administering compounds to rabbits in research?

Accepted Answer

All animal procedures must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. Procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and be performed by trained personnel. These requirements ensure humane treatment, minimize animal use, and maintain research integrity and compliance.
