Resistance to nematode parasites can be improved by selection, but efforts to include appropriate traits in commercial livestock breeding programs are only a recent development. Procedures for including resistance in breeding programs are similar to those involving other traits. The steps are des...


Woolaston, R.R.Baker, R.L.[Prospects of breeding small ruminants for resistance to internal parasites]Prospects of breeding small ruminants for resistance to internal parasites

This paper focusses on within-breed genetic variation in resistance to endoparasites in the Australian Merino. It stresses possible differences in the Merino resistance, simply because of different history of management. The Australian Merino was introduced into Australia 200 years ago. It has al...
