Regenerative Agriculture Project

The Challenge

Livestock are associated with a wide variety of pathogens, many of which are zoonotic as well as anti-microbial resistant bacteria, which are consequential to human and animal health. Grazing cattle are generally managed in one of two ways: rotational or conventional. Rotational grazing involves frequent structured movement of cattle through a series of small paddocks whereas conventional systems allow cattle to freely graze the same area of land for the duration of the season. The purpose of this study is to investigate the potential of rotational grazing to limit pathogen presence and persistence in agricultural environments.

Project Overview

Our study involved the collection of soil, fecal, surface water, and groundwater samples from nine beef cattle farms located in Southern Ontario from 2022 – 2024. Samples were analyzed for zoonotic pathogens including E. coli, Campylobacter, Cryptosporidium, and Giardia. While this project focuses on the effect of grazing type on pathogen presence, we also collected information on other farm practices and qualities that may impact animal and environmental health outcomes (eg. cattle type, age, feed type, number of animals present). This study provides an important opportunity to increase understanding of grazing management as a strategy to reduce pathogen presence on farms, thereby improving animal health, reducing human health risk, and consequently limiting the need of pharmaceutical interventions on farms.
