Compound administration is often an integral component of an animal study. Many factors need to be evaluated to ensure that the compound is delivered correctly. The route of administration affects the mechanisms of absorption. The characteristics of the substance to be introduced (the pH, viscosity, and concentration) may dictate which route of administration is selected.1,2,3
1. Topical application
The safest and most humane method of compound administration is through oral dosing if it is possible to incorporate it into the feed or water. Oral gavage is a precise dosing method but is also very stressful to the animal, and it requires technical proficiency. Topical administration is usually accomplished with little or no restraint of the animal, once the area is properly prepared. Careful consideration of the route of administration should factor in the potential stress to the animals.
