PARASITISM IN SOW REDUCES THE EFFICACY OF ALIMENTATION AND FAVORS PIGLETS CONTAMINATION

Internal and external parasitism of pigs has many consequences on anim al performances during all stages of production. Internal parasitism r educes alimentation profits (despoiling, wasting, anorexia) and so, in creases feed intake, decreases weight and number of piglets, and cause s bad immunisation after vaccination. External parasitism (scabies) in duces pruritus, highest energetic spendings and bad feed intake. Final ly, the sow is cause of piglets contamination. Use of anthelmintics be fore dropping allows better sows performances during pregnancy and lac tation and increases piglets ones because of their non-contamination.
