Abstract
Bovine Respiratory Disease Complex (BRDC) is a major cause of morbidity and
economic loss in cattle worldwide, driven by a multifactorial etiology involving
viral and bacterial pathogens, environmental stress, and immunosuppression.
Traditional interventions, including antibiotics and vaccines, remain the
mainstay of control; however, their effectiveness is increasingly constrained by
antimicrobial resistance, incomplete or short-lived protection, high costs, and
management challenges. These gaps underscore the urgent need for alternative or
complementary strategies. Phytochemicals from medicinal plants such as garlic (Allium
sativum), turmeric (Curcuma longa), and neem (Azadirachta indica)
demonstrate antimicrobial, antioxidant, and immunomodulatory activities, while
essential oils from species like Eucalyptus spp. exhibit strong
antimicrobial and anti-inflammatory effects. In vivo and in vitro studies
suggest that such compounds can enhance respiratory health, reduce pathogen
load, and strengthen immune responses in cattle. Yet, limitations related to
standardization, bioavailability in ruminants, regulatory frameworks, and the
lack of large-scale validation hinder their integration into veterinary
practice. This review highlights these gaps in current BRDC management and
provides new insights into how plant-based therapeutics, when developed as feed
additives, preventive tools, or adjuncts to conventional therapies, could reduce
antibiotic reliance and improve disease resilience in livestock systems.
