Equidae: Definition and Much More from Answers.com (2221 words) |
 | The potential for polygyny among equids is further enhanced because females are able to provide nutritional care for their young, and females do not come into estrus synchronously, which enables a male to mate with several females. |
| Equids are primarily grazers and have dental adaptations for feeding on grasses. |
| Wild equids in their native habitats are threatened by hunting for food and medicine, competition with livestock and people for access to water and forage, fragmentation and reduction of habitat, small population size, and inter-breeding with domestic horses and donkeys. |
| Viral Encephalitis Backgrounder (2860 words) |
| Equids with circulating VEE virus particles are capable of amplifying the virus and infecting others via insect vectors. |
| Humans and equids are considered dead-end hosts for WNV due to the low concentration of circulating virus particles associated with infection, and are not likely to serve as sources of disease transmission to other susceptible hosts. |
| JEV infection in equids is associated with a 0 to 10% case fatality rate in endemic areas, but outbreaks have resulted in case fatality rates as high as 40%. |
