Parasites and Animal Care
Abstract
Parasitic infections present a major global challenge to animal health and agricultural sustainability, leading to substantial economic losses and zoonotic risks to human health. The economic burden is particularly severe in the livestock sector, with annual losses estimated in billions of US dollars due to reduced productivity from parasites, such as gastrointestinal nematodes and ticks. Parasites affecting livestock and companion animals are categorised as internal (endoparasites), such as helminths (e.g. Nematodes and Cestodes), protozoa (e.g. Giardia duodenalis and Toxoplasma gondii), and external (ectoparasites), dominated by arthropods, such as fleas, ticks, and mites. These infestations significantly impair animal welfare by causing distress and severe health issues; reducing growth rates through resource competition and physiological stress; and diminishing productivity by negatively affecting weight gain, milk production, and reproductive performance. The economic consequences are further compounded by increased veterinary costs, diminished market value, production losses, and development of drug-resistant parasite strains. To address these multifaceted issues, an Integrated Parasite Management (IPM) approach is essential. IPM involves a holistic combination of sustainable preventative measures (such as strategic grazing, breeding for resistance, and biosecurity), timely diagnostic techniques (such as Faecal Egg Counts and FAMACHA scoring), and targeted treatment options (such as smart drenching and exploring alternative therapies). Adopting a One Health approach, which integrates modern diagnostics, sustainable practices, and traditional knowledge, is crucial for mitigating the global impact of parasitic infections and ensuring long-term health, productivity, and environmental sustainability.
