Fig. 1.

Cryptosporidium and Giardia infection patterns differentiated by halofuginone lactate (HL) treatments. Calves were assigned into groups retrospectively based on HL treatment regiments (separated by dashed lines on figure): ¹) not treated (n = 34), ²) treated incorrectly (treatment started > 48 h after birth, or lasted < 7 days) (n = 45), and ³) treated according to manufacturer's instructions (started < 48 h after birth, and lasted ≥ 7 days) (n = 65). (◆) Cryptosporidium positive; (○) Giardia positive; (·) Giardia and Cryptosporidium negative; (+) death (n = 17); horizontal lines represent HL treatment and the length represents the treatment in days. The y-axis represents the birth order of calves in different HL treatment groups, starting with the oldest and ending with the youngest; x-axis represent the age of the calf.
