%T Gestion du Parasitisme des petits ruminants en Agriculture Biologique
%X The general objective of the project was to evaluate alternative methods of control of nematode parasitism in small ruminants.  

More specifically, the project aimed at 

1 developing novel methods of diagnosis in order to use more efficiently the available chemical anthelmintics. Novel methods have been developed  
either on animals or through  analysis of the pasture grazing system 
 
2 assessing the interest in organic farming of mixed grazing between cattle and 
sheep for the control of  helminth  parasitism of the gastrointestinal tract.

The materials and methods used are:

- In vivo parasitological and pathophysiological measurements on two flocks: one of cattle plus sheep in mixed grazing conditions and one of sheep alone.

- Improvement of diagnosis on animals : development of methods of measurement of antibodies against nematode and Oestrus ovis in milk. Comparisons with  similar parameters  measured on blood.

- Risk  analysis of pasture system  to approach the level and dynamics of   parasite infections and predict when to use efficiently chemical drugs.  

*A guide  on  ?Better use of pasture in goat production ? is currently being developed  for  goat farmers which include our main results on risk analysis through examination of pasture systems
