At the Charles River Laboratories facility in Nevada, positive Human Interaction (HI) occurs at least two times per week. Technicians are required to offer the animals a food treat from their hand. If the animal takes the treat, then it is offered another one as a reward. If the treat is not taken, then it is placed in the feed box. It has been suggested that offering the animals HI establishes trust between the staff and animals, creates a positive relationship, and helps to reduce stress. For this study, subjects were chosen from two separate shipments (Group 1 and Group 2) and each group consisted of 17 males and 17 females. Animals came from breeding facilities in China and were in a Center for Disease Control-required imported quarantine period for approximately 4 weeks and housed individually. During the quarantine period, Group 1 was desensitized to certain study stimuli 3 times a week. The animals received HI on the days when they were not being desensitized. During week one, 6% of Group 1 animals accepted HI, versus 3% of Group 2 animals. By week four, 21% of Group 1 animals accepted HI compared with 3% of Group 2 [Mann-Whitney U Test: P<0.005]. These data show that training has a large impact on the treat acceptance rate between the two groups.
