In Cuba, five of eight 2-month-old Holstein or Cebu calves were infected with 250 F. hepatica metacercariae. Epg was monitored from 2 weeks before to 40 days after infection and haematology from one week before until slaughter 8 months later. The prepatent period was from 45 to 67 days. Total leucocyte count began to increase 2 weeks after infection and peaked at about 55 days.
