     Few published accounts exist describing the long-distance relocation of non-human primate social groups and the social and clinical consequences of such a move. Yerkes National Primate Research Center acquired nine intact social groups of rhesus macaques (n=97) from another primate facility during two separate time points in 2014. Groups were transferred from an indoor facility to outdoor sheltered housing at Yerkes Field Station. Group size ranged from 4-15 and individuals ranged in age from one month-17 years old at time of shipment. The first cohort of monkeys (n=40; 21 females), were relocated in the spring and experienced a quick transition to Yerkes standard diet whereas the second cohort (n=57; 27 females), relocated in fall and experienced a gradual diet transition. Body weights were collected prior to relocation and during five quarantine examinations, approximately 2-3 weeks apart. These data show significant weight loss across both cohorts of adult females between pre-shipment and 90 days post-shipment (mean difference = 0.87kg-1.25kg) (F=32.17; p<0.001). Additionally, the overall weight loss among female adults between the two cohorts was significant (% change: cohort 1= 12.92%; cohort 2= 15.16%) (F=3.15; p<0.017); however, multiple linear regression indicates starting pre-shipment weight was a higher predictor of weight loss (F=18.48; p<0.001). These data suggest that even with a gradual diet transition, significant weight loss in larger animals following relocation is likely to be unavoidable.
