Abstract
Fecal samples were examined between 17 September and 1 November 1993 from 1765 cattle (one bull, 533 cows, 474 heifers, 22 steers, and 735 calves) on pasture on 15 farms in 11 countries in Kentucky for eggs or larvae of internal parasites. All of the cattle were beef-type except for 22 which were dairy-type. In fecal samples from the bull, cows, heifers, steers, and calves, the types of helminth eggs present were trichostrongyles (excluding Nematodirus) in 0%, 25%, 31%, 86%, and 93%, Nematodirus in 0%, 0%, <1%, 0% and 34%, Strongyloides in 0%, 0%, <1%, and 7%, Trichuris in 0%, 0%, 0%, 0%, and 2%, Capillaria in 0%, 0%, 0%, 0%, and <1%, and Moniezia in 0%, 1%, 8%, 5%, and 21%, respectively. Dictyocaulus viviparus larvae were present in feces of calves (7%) on one farm and heifers (<1%) on another farm.
