Total time spent in each behavior category were plotted to show strain difference. Note that WKY/NCrl rats spend significantly less time in direct contact with the littermates (when not fighting) than all other three strains including WKY/NHsd, although the two WKY substrains were highly similar in all four other measurements. SHR is similar to SD rats in non-fighting physical contact, rearing and inactivity levels. However, SHR spent more time in fighting and less time in self-grooming than SD. Significant post-hoc comparisons were denoted with "*".
