INMD- Nematodes in the digestive system

 

Nematode infections are present on a world scale and cause major pathological problems in ruminants having an impact on health and well being in production animals and therefore effecting farm economics.

Synthetic anthelmintics have long since been the preferred method of control of nematodes. This has encouraged development of resistance to treatment options, which has lead to the need to find alternative solutions to chemical treatments in addition to demands from society to decrease chemical use in food production. This requires a better understanding of the host pathogen interactions. The latest concept is to explore the use of foods having positive health benefits. To explore this concept, the group studying dairy producing goats and sheep, fed with foraged vegetables that are high in tannins and polyphenols, which are believed to have an effect in nematodal infections.
