I am planning to initiate a single dose toxicity study in rats. And I have an option of using either the SD rats or Wistar Rats. Which strain should I choose? Do Wistar Rats have a preference over SD rats for toxicity studies?
These two strains of rats are different, but rats are often used in toxicological studies. You need to make your own choice based on previous work (some other researchers or your own). Personally I would choose Wistar.
