The Sprague Dawley is an outbred, multipurpose breed of albino rat used extensively in medical and nutritional research.[1][2][3][4] Its main advantage is its calmness and ease of handling.[5] This breed of rat was first produced by the Sprague Dawley farms (later to become the Sprague Dawley Animal Company) in Madison, Wisconsin, in 1925. The name was originally hyphenated, although the brand styling today (Sprague Dawley, the trademark used by Envigo) is not. The average litter size of the Sprague Dawley rat is 11.0.[6]
These rats typically have a longer tail in proportion to their body length than Wistars. They were involved in the Séralini affair, where the herbicide RoundUp was claimed to increase the occurrence of tumor in these rats. However, since these rats are known to grow tumors at a high (and very variable) rate, the study was considered flawed in design and its findings unsubstantiated.
