Background Gastrointestinal nematode (GIN) infections are common in domestic sheep and
impact directly and indirectly on the health of infected animals as well as on the associated …

Infections with gastrointestinal nematodes (GIN) remain a major threat for ruminant
production, health and welfare associated with outdoor breeding. The control of these …

Interactions between host nutrition and feeding behaviour are central to understanding the
pathophysiological consequences of infections of the digestive tract with parasitic …

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

Grazing systems have great potential to promote animal welfare by allowing animals to
express natural behaviours, but they also present risks to the animals. Diseases caused by …

Gastrointestinal nematodes (GIN) could have a negative impact on the nutritional efficiency
and productivity of sheep and goats. However, feeding of the hosts can also affect parasites …

Studies in genetics and breeding of sheep in Brazil have increased significantly in recent
years. These involve research in characterization, breeding and crossing sheep using new …

This study evaluated the economic impact of gastrointestinal nematode (GIN) infection in
Morada Nova lambs under different parasite chemical control conditions. For this, 246 …

Helminthiases are among the most important livestock diseases worldwide, in particular for
small ruminants, which are the focus of this review. Resource Allocation Theory implies that …

It is increasingly being recognized that non-chemical parasite control strategies may need to
be combined to control more effectively gastrointestinal parasitism, result in resilient …
