Immunocontraception and increased longevity in equids
Abstract 10.1002/zoo.20109.abs Intensive population management by means of fertility control has been shown to change the age profile of a wild horse herd. The primary change has been an increase in the number and percent of older animals, as expected, but also the appearance of new and older age classes. An examination of direct effects […]
Water consumption and watering behavior of Przewalski horses (Equus ferus przewalskii) in a semireserve
Abstract 10.1002/(SICI)1098-2361(1998)17:33.3.CO;2-M Water consumption by 12 female Przewalski horses was automatically measured in a semireserve for 17 months. Average daily consumption on a yearly basis was between 2.4 and 8.3 liters, but significant individual variation in water consumption and drinking frequency was recorded throughout the observation period. Individual differences were more clearly detectable during periods […]
Behavioral patterns and communication in feral asses (Equus africanus)
The behavior of feral populations of the African wild ass (Equus africanus) were studied in the Northern Panamint Range of Death Valley National Monument for 20 months from 1970 to 1973 [Moehlman, P.D., 1974. Behavior and ecology of feral asses (Equus asinus). PhD dissertation, University of Wisconsin, Madison, 251 pp.; Moehlman, P.D., 1979. Behavior and […]
Feral asses of volcano alcedo galapagos: behavioral ecology, spatial disribution and ocial organization
Feral asses were studied on Volcano Alcédo, Galapagos Islands, Ecuador, during the wet season of 1980. On the volcano rim during March/April, two stable groups were observed to have a `female (harem) defense’ polygynous mating system [Emlen, S.T., Oring, S.W., 1977. Ecology, sexual selection, and the evolution of mating systems. Science 197 (4300), pp. 215–223] […]
Affiliative and aggressive behavior in a group of female somali wild ass (Equus africanus somalicus)
We observed a group of three young female Somali wild asses to develop an ethogram of social behavior in the first phase of a longer term study of social, sexual, and maternal/infant behavior. The most unexpected finding was the frequency and extent of aggressive interactions, which included Charge, Drive, Neck Wrestle, Head Butt, and Body […]
How to keep your horse safe? An epidemiological study about management practices
As animal welfare has become a major societal concern since the last decades, identifying the factors affecting it, is of first importance. Many studies have been conducted, mostly centred on one particular environmental factor. However, animal welfare is multifactorial, and evaluating the management as a whole seems more appropriate. In this particular study, we aimed […]
