Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

Year: 2026

Type: article

Abstract: ABSTRACT Grazing ruminants have long faced threats from gastrointestinal nematodes (GINs), which affect their well‐being, health, and agricultural productivity worldwide. Researchers and farmers are collaborating to explore non‐chemical methods for controlling these parasites, driven by increasing drug resistance and concerns about chemical residues from consumers and the environment. Since organic and sustainable farming systems restrict the use of antiparasitic medications, there is an especially pressing need for non‐chemical methods. This review evaluates the potential of dietary treatments, including protein and energy supplements, to boost host resistance and resilience by examining the links between gastrointestinal nematode infections, animal nutrition, metabolism, and immunology. In addition to nutrition‐based approaches, we also examine other management strategies, such as the use of plant‐derived bioactive compounds, breeding for parasite‐tolerant strains, vaccines, nematode‐predatory fungi, and smart grazing practices that disrupt parasite life cycles. No single method can fully eliminate parasitic infections. A sustainable solution involves adopting a One Health approach that integrates animal health, human health, and environmental sustainability. By combining multiple strategies, we can reduce dependence on synthetic anthelmintics, improve ruminant production efficiency, and safeguard ecosystems.
