Table 2.
Nematode egg per gram counts (EPG, arithmetic mean, range) and reduction percentages of faecal egg counts (FECR) (undifferentiated) with its 95% lower and upper confidence intervals, after the oral administration of monepantel (MNP, 2.5 mg/kg), and the subcutaneous administration of ivermectin (IVM, 0.2 mg/kg) and ricobendazole (RBZ, 3.75 mg/kg) to naturally parasitized calves.

EPG counts on each column with different superscript letters are statistically different (P < 0.05).

FECR estimated according to McKenna (1990). CI: lower and upper confidence intervals.
