Grape pomace as systemic antibiotic alternative reveals agro-industrial waste-to-resource gaps and monoculture dependency in poultry systems

Scientific studies confirm that grape pomace contains polyphenols and tannins with antimicrobial properties, which can inhibit pathogenic bacteria in poultry gut microbiomes. However, the efficacy varies by grape variety, processing method, and poultry breed, and long-term impacts on bird health and meat quality remain understudied. The research also often overlooks the ecological trade-offs of scaling up pomace collection, such as increased fuel use for transport or competition with other uses like composting or biofuel production.
The narrative of grape pomace as a 'solution' to antibiotic overuse in poultry farming exemplifies how industrial agriculture externalizes costs—both environmental and social—while framing innovation as a technical fix rather than a systemic overhaul.
Historically, the separation of winemaking and poultry farming into siloed, monocultural systems created the very problems this 'solution' aims to address, revealing a paradox where waste is both a symptom and a band-aid. Indigenous traditions, which have long practiced circular agriculture, offer a blueprint for reintegrating these systems, but their knowledge is sidelined in favor of Western scientific paradigms that prioritize scalability over sustainability. The trickster’s lens exposes the absurdity of celebrating a single byproduct as innovation while ignoring the structural violence of industrial food systems, where corporate consolidation and regulatory capture shape what counts as a 'problem' and what passes as a 'solution.' True transformation requires not just repurposing waste but reimagining the relationships between land, labor, and life—where grape pomace is one thread in a tapestry of agroecological resilience, not a standalone fix.
