Haemonchus contortus (Barber's pole worm or “BPW”) is the nematode “nemesis” of small
ruminant production systems in tropical and subtropical regions of the world. Its reputation …

Gastrointestinal nematode infection represents a major threat to the health, welfare and
productivity of sheep populations worldwide. Infected lambs have a reduced ability to absorb …

Sheep are capable of developing protective immunity to Haemonchus contortus through
repeated exposure to this parasite, although this immune protection is the result of a …

The control of gastrointestinal nematodes (GIN) is mainly based on the use of drugs, grazing
management, use of copper oxide wire particles and bioactive forages. Resistance to …

This paper examines the known immunological and genetic factors associated with sheep
resistance to infection by Haemonchus contortus. Such resistance is an inheritable genetic …

Genomic structural variation is an important and abundant source of genetic and phenotypic
variation. We previously reported an initial analysis of copy number variations (CNVs) in …

Gastrointestinal nematodes (GINs) can be a major constraint and global challenge to the
sheep industry. These nematodes infect the small intestine and abomasum of grazing …

Selection of genetically resistant animals is one alternative to reduce the negative impact of
gastrointestinal nematodes (GIN) on sheep production. The aim of this study was to identify …

Genetic markers for sheep resistance to gastrointestinal parasites have long been sought by
the livestock industry as a way to select more resistant individuals and to help farmers …

The gastrointestinal tract (GIT) has multiple functions including digestion, nutrient
absorption, secretion of hormones and excretion of wastes. In the ruminant animal …
