Observations on the maternal behaviour of free-ranging domestic pigs

Video recordings made inside wolf dens chronicle two episodes of infanticide by different α females within a captive pack of timber wolves (Canis lupus). In one instance, infanticidal behaviour was interspersed with maternal behaviour. These cases are discussed in terms of the proximate causes of infanticide. It is also suggested that the killing of pups born to subordinate females by α females may be a common occurrence in both captive and free-ranging wolf packs.

Enzootic Area

SUMMARYA serological survey of free-ranging domestic pigs in the Central and Southern Regions of Malawi, together with laboratory data on confirmed cases of African swine fever (ASF) and data from interviews with pig owners, undertaken over a four-year period from 1981–4, has enabled the ASF enzootic area of Malawi to be identified. The area covers much of the western part of the Central Region and includes Mchinji district and parts of Kasungu, Ntchisi, Dowa and Lilongwe districts. Mortality is substantially less than 100% in outbreaks within the enzootic area but approaches 100% in outbreaks outside this area, as shown by both the serological investigation and the interview data.
