AbstractBehavioral observations on a large group of free-ranging rhesus monkeys (Macaca mulatta) were carried out on Cayo Santiago from January I968 through December I969 and from October through December I970. Records of mating activity (single mounts, mount series, copulations) indicated that genealogical mating activity on Cayo Santiago had the following characteristics : (I) 5.4% of all recorded mount series and copulations involved mother-son pairs; (2) mating was observed in 3I% of 26 individual pairs of mothers and sons; (3) mating was seen in I2% of 42 individual pairs of brothers and sisters; (4) of I0 instances of mother-son mating, seven involved pairs in which the mother was dominant to the son; (5) mating in mother-son and brother-sister pairs occurred in high and low ranking genealogies within the group; (6) with two exceptions, all three to five-year old males who did engage in sexual activity with their mothers did not mate with non-related females during that breeding season; and (7) with one exception, all instances of mother-son and brother-sister mating involved males from three to five years of age. These findings are in sharp contrast to observations made on a smaller group on Cayo Santiago. Possible causes for this difference between social groups of different size are discussed.

Routine Handling

Bodyweight is an important health and welfare indicator for captive non-human primates (NHPs). Bodyweight can be measured during routine handling procedures, which cause stress. Alternatively, animals can be trained to step onto a scale, but training success varies greatly between individuals. Being able to weigh animals regularly without having to handle or train them is thus desirable for monitoring animal health and welfare. This study investigates the utility, ie the participation, reliability and time investment, of voluntary weighing in captive NHPs living in large social groups. Subjects of the study were 92 rhesus macaques (Macaca mulatta) housed in four social groups at the Biomedical Primate Research Centre in Rijswijk, The Netherlands. A scale was placed in their home enclosure during several sessions. Individuals were unwilling to step onto an unbaited scale. When likeable food items were used to attract individuals to the scale, 68% of them stepped onto the scale. Age and dominance rank did not affect stepping onto the scale, whereas exploratory tendency and social group did. The level of agreement between bodyweight by voluntary weighing and bodyweight measured during sedation was very high. These results show that the majority of rhesus macaques in social groups can be weighed voluntarily and that voluntary weighing is reliable. When optimising and further developing the method, voluntary weighing can form a valuable tool in the captive management of NHPs.
