Ratology

History & Background

The Sprague Dawley, derived from the Winster rat, is the most widely used outbred albino in animal research and is characterized by it good temperament, sociability, calm demeanor, and ease of handling. This laboratory rat, first breed by Sprague Dawley in Madison, Wisconsin, is used most frequently in medical research and has aided to increased knowledge in fields such as genetics, learning, pharmacology, toxicology, oncology, and nutrition.

 

General Information

            Sprague Dawley’s, like most rats, are highly social and enjoy the company of others. Without proper attention and socialization, they can become depressed, develop neurological problems, or aggressive. Rats are intelligent creatures that can be easily trained to do various tasks such as coming when called and even to use a litter pan. Like most animals, rats are prone to health problems including respiratory infections, mites, abscesses and tumors. Therefore it is important to monitor for symptoms related to these health issues such as sneezing or wheezing, scabbing, and abnormal growths.
