The spread of weeds into sensitive areas by seeds in horse faeces.

The research investigates how horse faeces can potentially spread invasive plant seeds in sensitive areas. The study discovered that seeds eaten by horses can stay in their digestive system for 24-48 hours before being excreted and the cycle of ingestion and excretion doesn’t impact the seeds’ ability to sprout.

Objective of the Research

• The central aim of this research is to investigate the potential role of horse faeces in the spreading of plants which might turn into invasive species in sensitive areas.

Methods Used in the Research

• Seeds were fed to horses and then, the timing of excretion was monitored to determine the retention time of these plant particles within the equine digestive system. This forms the basic premise of the research methodology.
• The study also examined whether exposure to digestive fluids or seawater affects the viability of the seeds and their ability to germinate.

Findings of the Research

• The research found that the digestion process in horses typically retains seeds for a period of 24-48 hours before they’re excreted.
• Despite being subjected to digestive fluids and conditions within the horse’s body, the seeds retain their capacity to germinate.
• The impact of seawater on the germination ability of these seeds was also studied and it was found that even exposure to seawater didn’t affect the seeds’ viability. This suggests that horse faeces can potentially transport seeds over large distances, especially in coastal areas.

Suggested Solution

• To counteract the spread of potentially invasive species through horse faeces, the researchers suggest implementing a feed regime that comprises compound feeds. This could potentially reduce the prevalence of harmful seeds in the horse’s diet and, consequently, their spreading capacity.
