RESUMEN

Targhee and Targhee-Barbados Black-Belly cross lambs that were raised helminth-free were experimentally infected with 10,000 or 25,000 infective larvae of Haemonchus contortus. There were no significant (P = less than 0.05) differences in results of weight gain, packed cell volumes, numbers of eggs per gram of feces, or numbers of helminths between the 2 groups of lambs.
