The Effect Of Management Strategies On Haemonchus Contortus Infections Of Sheep And Goats On Intensively Grazed Pasture, Catherine Werker Pouliot

The purpose of this study was to determine how the management strategies used by producers on sheep and goat farms in Maine, New Hampshire, and Vermont could affect the fecal egg counts of the parasite called Haemonchus contortus in their animals. Surveys about management practices and fecal samples from the juvenile and adult populations were collected during the months of June, July, and August in the summer of 2015. Next, the samples were analyzed and fecal egg counts were determined using the McMaster method and a fluorescence-based H. contortus speciation technique. The fecal egg counts and survey answers were compiled …

Abomasal worms are a major cause of small ruminant disease. Differentiation of the most pathogenic nematode, H. contortus, from the other common species can be difficult using standard diagnostic fecal floatation techniques because the ova are similar in size and morphology. Known pure culture H. contortus fecal samples from West Virginia University were used to develop morphologic assays using FITC-labeled lectin agglutination and immunocytochemistry to identify species of abomasal worms. These assays were applied to assess disease due to abomasal worms on selected small ruminant farms in Maine. The diagnostic tests were used to test the hypothesis that H. contortus …
