Table 1.

Hatching rates of eggs in water (control) or after MβCD treatment (2.25 mM). The MβCD treatment had no toxic effect. Percent hatching rates (means of three egg hatch assays) of treated eggs weighted according to the percent hatching rate in control samples.

	HcS-WB	HcS-Ca	HcR-WR	HcR-G
Untreated eggs	100	100	100	100
MβCD (2.25 mM)	106.5	98.7	105.3	110.5

HcS-WB: Haemonchus contortus susceptible Weybridge, HcS-Ca: Haemonchus contortus susceptible Canada, HcR-WR: Haemonchus contortus resistant White River, and HcR-G: Haemonchus contortus resistant Guadeloupe.
