A successful program for same- and cross-age pair-housing adult and subadult male Macaca fascicularis (2002)

Watson, L. M.

Abstract

Isosexual pairs of adult males, adult male/juvenile male and adult females were established and pair compatibility ascertained throughout follow-up periods of 1 month to 3 years. Partners were introduced after a carefully supervised noncontact familiarization period in a specific pair formation cage placed in a location other than the animals' homeroom. Of 31 adult male pairs tested, 29 [94%] were compatible; two pairs had to be separated because one animal in each pair sustained injuries during minor fighting.Article includes a photo clearly demonstrating the conspicuous light difference between upper- and lower-tier cages plus conventional perches that are installed at such low level that animals cannot make use of the space below of them.
