“…Contact with females involves sociosexual stimuli, which result in an increase in luteinizing hormone and testosterone production in domestic and wild ruminant males (cattle: Katongole et al 1971;buffalo: Malfatti et al 2006;ovine: Gonzalez et al 1988aovine: Gonzalez et al , b, 1991Pelletier et al 2003;goat: Walkden-Brown et al 1994;Giriboni et al 2017;Longpre et al 2016;deer: Villagrán and Ungerfeld 2013). This stimulus was also associated with a higher frequency of aggressive and courting behaviors (Illius et al 1976), and higher reproductive success (Carrillo et al 2011) in males in contact with females than in those isolated from them.…”

The addax antelope (Addax nasomaculatus) is a species under serious threat of extinction, as it is more abundant in captivity than in the wild. However, little is known about its basic biology. The aims of this study were to determine how locomotor, feeding, aggressive, marking, and sexual behavior of male addax allocated in all-male groups vary with season and with female contact (i.e., biostimulation). The study was conducted in captive conditions, in two groups of adult males: one with no-physical contact with females, aside from visual and olfactory interactions (CF group, n = 4), and another group completely isolated from females (IF group, n = 4). The frequency of behaviors was recorded during the daytime, 4 days per season (total time of observation = 256 h). Lying, standing, walking, aggressive, marking, grazing, and ruminating behaviors as well as water and supplement consumptions varied with season (all p < 0.05). The lying, walking, marking, grazing, and ruminating behaviors were more frequently observed for CF than IF males (all p < 0.05). Also, all behaviors, except for marking, varied with the interaction between the group and seasons (all p < 0.05). Sexual behavior was extremely scarce, so it was not possible to analyze how it varied with seasons and the group. The present study suggests that management program and housing conditions, especially in ex situ breeding plans, should consider the influence of the season and the sociosexual context on the behavior of addax males.
