Efficacy Of Maine Lobster Shell As Treatment For Haemonchus Contortus Parasitism In Sheep, Morgan H. Gustin
Efficacy Of Maine Lobster Shell As Treatment For Haemonchus Contortus Parasitism In Sheep, Morgan H. Gustin
Honors College
Lobster shell, a chitin-based material, was applied to the ova, and to the L3 and L4 larval stages of the ruminant nematode Haemonchus contortus to assess its nematicidal effects on the parasite. Methods were developed to more accurately characterize and quantify larvae, including a formalin-kill technique to establish larval viability and a procedure for culturing L3 stage larvae into L4s in AF. Larval cultures containing 80g of fecal matter, 30g vermiculite and 100ml water were treated with various proportions of crushed lobster shell (medium or fine crush) to assess the affect of lobster shell on the maturation of H. contortus …

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