The colony history began with a colony of rats established by Robert
Dawley around 1925. SD rats are often referred to as "Spargue-Dawley®"
Mr. Dawley used both his name and the maiden name, "Sprague", of his wife
to create the name of the stock. The colony then went to Sprague Dawley,
Inc. in 1945. NIH began a closed colony with animals obtained from
Sprague Dawley, Inc. Hilltop Lab Animals, Inc. received animals from NIH in 1984. Through cesarean rederivation, the animals were |
fostered onto gnotobiotic rats in isloation. Descendents of these animals
then became the colonies currently available. All colony histories contain some possiblity of inaccuracy. This information is being provided to the best of Hilltop's knowledge. The coat color of the rat is albino. The rat is propagated using an outbred breeding system. The colonies, located at Hilltop Lab Animals, Inc., are closed colonies and have been so since 1985. Closed colonies do develop qualities causing the rats to be uniquely suited to certain types of research. |
