In this overview, the results of studies in France were given on the genetic variability in resistance to helminth parasites in Romonov and Merino d'Arles sheep and Saanen and Alpine goats. The paper focusses on diversity of helminth parasites, innate vs acquired resistance, criteria for genetic ...
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...
The paper focusses on the genetic control of immunoresponsiveness in Trichostrongylus selection lines. It discusses results from other selection programmes in which some characterisation of the immune - response system has been undertaken. It is Reported that some aspects of this work may not hav...
