The Effect Of A Condensed Tannin Containing Forage, Sericea Lespedeza On Existing And Challenge Infections Of Haemonchus Contortus In Sheep, Leigh Ann Chafton
The Effect Of A Condensed Tannin Containing Forage, Sericea Lespedeza On Existing And Challenge Infections Of Haemonchus Contortus In Sheep, Leigh Ann Chafton
LSU Master's Theses
Haemonchus contortus is one of the most threatening parasites to small ruminant production. Control has traditionally relied on the use of anthelmintics. Control has waned because the worm population has developed resistance to most of the currently available anthelmintics and alternative control measures are needed. Current consumer pressure is to reduce the use of chemicals in agricultural products, thus pushing control methods to more natural and acceptable approaches. One such approach is the feeding of condensed tannin containing forages either as fresh forage or dried products (hay, meal, pellets, etc). This study was conducted to determine the effect of a …
Effect Of Vaccination Of Goats With H-Gal-Gp And H11 Antigens From Intestinal Membrane Cells Of Haemonchus Contortus, Donya Dupree Olcott
Effect Of Vaccination Of Goats With H-Gal-Gp And H11 Antigens From Intestinal Membrane Cells Of Haemonchus Contortus, Donya Dupree Olcott
LSU Master's Theses
Extracts of adult Haemonchus contortus were purified and used as a vaccine against the blood feeding parasite in goats as previously studied in sheep. The proteins used were H11 and H-gal-GP, hidden gut antigens from the microvillar membrane of the gut of the worm and combined with Quil A as adjuvant, then administered to a group of goats kept on concrete then artificially infected with H. contortus. The control group received Quil A injections and also infected. This study was performed to analyze the effects of the H11/H-gal-GP vaccine when given to goats as compared to sheep. The trial showed …
