Il momento giusto per la lotta alla fasciolosi epatica dei bovini

Studies on 2 farms in Como province, Italy, that moved their herds to mountain pastures for the summer showed that a mean infestation of 30-50 liver flukes resulted in a 10% loss in milk production, a prolongation of the parturition to conception interval of about 13 days, and an increase of 0.75 services per conception. Animals at risk should be monitored by ELISA tests on milk and faecal examination; treatment is with a fasciolicide (albendazole).
