Haemonchus contortus is a highly pathogenic, blood-feeding nematode of small ruminants,
and a significant cause of mortalities worldwide. Haemonchosis is a particularly significant …

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 …

Haemonchus contortus appears to be the most economically important helminth parasite for
small ruminant production in many regions of the world. The two sheep breeds native to the …

Individuals vary broadly in their response to vaccination and subsequent challenge
infection, with poor vaccine responders causing persistence of both infection and …

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 …

Resistance to gastrointestinal nematodes has previously been shown to be a moderately
heritable trait in some breeds of sheep, but the mechanisms of resistance are not well …

Genome-wide association studies (GWAS) have been used as an effective tool to
understand the genetics of complex traits such as gastrointestinal parasite (GIP) resistance …

Gastrointestinal nematodes are a major threat to small ruminant rearing in the Sahel area,
where farmers traditionally use bioactive plants to control these worms, including Acacia …

Litter size, which is a complex economic trait in sheep, is affected by polygenes. Hu sheep
are a prolific native breed in China and also an ideal resource for studying the genetic …

Gastrointestinal nematode (GIN) infection of ruminants represents a major health and
