Information About endocrine diagnostics

Hormones associated with reproduction and adrenal function are easily measured non-invasively in urine and faeces and we’ve established and endocrine laboratory with the capacity to measure these hormones.

What kind of diagnostic questions can you answer using reproductive hormone assessment?

  • Are my animals seasonal breeders?
  • Has my animal reached puberty?
  • Is my animal cycling on a regular basis or is she acyclic?
  • When will be the optimal time for introduction of the female to the male?
  • Is my animal pregnant?
  • When will my animal give birth?
  • Has the chosen method of contraception been effective?

For example, female black rhinos are very particular about when males can approach them for breeding; therefore, introductions between the male and female need to be perfectly timed to avoid aggression.

Take a look at our Endocrine Diagnostic Services leaflet for examples of our work.

What kind of diagnostic questions can you answer using adrenal hormone assessment?

Adrenal hormone (or ‘stress hormone’) analysis is commonly used in assessing animal welfare. The Reproduction & Welfare Research Unit offers assays to measure these hormones but usually only as part of a collaborative research project.

Our hormone assays can be used for a wide range of wildlife and domestic species.

Please contact us before sending any samples for analysis at endocrine@chesterzoo.org
