Trichostrongylidae

The relationship between these parasites and agriculture lies in the transmission pathway. Eggs are shed via the feces of infected animals onto pastures, where they hatch into larvae. These larvae then migrate onto blades of grass, making the pasture environment a key transmission site for livestock.

The biology of Trichostrongylidae relies heavily on environmental conditions. Larvae are sensitive to desiccation but can survive for several months in damp, cool environments, particularly within the protective microclimate of dense swards on agricultural pastures.

The damage caused by these parasites includes significant weight loss, anemia, diarrhea, and reduced milk production in livestock. If left untreated, severe infestations can lead to high morbidity and mortality, severely impacting the efficiency of animal husbandry operations.

Management and control strategies include:

• Implementation of targeted anthelmintic treatment programs for livestock.
• Rotational grazing systems to minimize ingestion of infective larvae from pasture grass.
• Monitoring of pasture quality and stocking density to reduce the risk of environmental contamination.
• Use of dry, raised feeding areas to prevent direct contact with contaminated soil or vegetation.
