Fermented coffee cherry pulp shows promise in Thai native chickens

Fermented coffee cherry pulp is drawing fresh attention as a poultry feed ingredient after a new study in Animals reported gains in growth performance, meat quality, and cecal microbiota in Thai native chickens. In the 12-week trial, researchers tested three inclusion levels against both a basal diet control and an antibiotic growth promoter comparator, finding that 1.0 g/kg appeared to offer the best balance of benefits. The work points to a familiar industry goal: finding feed additives that support performance and gut health while reducing reliance on conventional antibiotic growth promoters. (mdpi.com)

The background is important here. Coffee cherry pulp is a major by-product of coffee processing and is often treated as waste, even though it contains carbohydrates, fiber, caffeine, and phenolic compounds, including chlorogenic acid. Chiang Mai University-linked researchers have been building a body of work around this ingredient, including a 2025 Animals paper showing coffee cherry pulp extract improved broiler growth, intestinal morphology, cecal bacterial profiles, and some serum and carcass measures, with the authors explicitly positioning it as a possible antibiotic alternative. Related work published in 2025 also showed fermentation can improve the digestibility and antioxidant capacity of coffee cherry pulp, supporting its use as a value-added poultry feed ingredient rather than a disposal problem.

That broader context helps explain why the Thai native chicken study matters. Fermentation is being used not just to preserve the ingredient, but to make it more biologically useful by improving nutrient availability and antioxidant potential. In a 2025 Animals paper on fermented coffee cherry pulp bioconversion, researchers reported higher peptide release and stronger antioxidant activity after fermentation, with the authors framing the process as a way to enhance bioaccessibility and support sustainable feed applications. In other words, the new chicken study is part of a larger effort to turn a regionally abundant coffee by-product into a more standardized functional ingredient. (mdpi.com)

Mechanistically, chlorogenic acid is one of the key compounds drawing attention. A 2026 review in Veterinary Sciences said chlorogenic acid is increasingly studied in chickens for its role in regulating oxidative stress, lipid metabolism, inflammatory signaling, intestinal barrier integrity, and the gut–liver axis. The review points to pathways involving AMPK, Nrf2, and NF-κB, and suggests chlorogenic acid may help maintain chicken health by modulating gut microbial composition and short-chain fatty acid production. That doesn’t prove causation in the Thai native chicken paper, but it gives a plausible biological rationale for why fermented coffee cherry pulp could influence both feed efficiency and cecal microbiota.

Industry reaction wasn’t readily available in the form of outside quotes tied specifically to this new paper, but the research direction lines up with a wider push toward upcycled feed ingredients and antibiotic-sparing production tools. The broiler study from the same research group found coffee cherry pulp extract improved final weight, average daily gain, feed conversion, intestinal villus structure, and Lactobacillus counts, while reducing pathogenic bacteria and lowering some liver enzyme and triglyceride measures. Taken together, those findings suggest the authors are moving from proof-of-concept around coffee by-products toward a more practical feed-additive case. That’s still early-stage evidence, but it’s more credible than a single isolated result. (mdpi.com)

Why it matters: For veterinarians and technical teams in poultry production, the immediate relevance is less about coffee specifically and more about the type of intervention. Feed additives that can improve gut health, carcass outcomes, and feed conversion without leaning on antibiotic growth promoters remain a priority, especially where antimicrobial stewardship, export expectations, or consumer pressure are shaping production decisions. This study also matters because it focuses on Thai native chickens rather than only fast-growing commercial broilers, which may make the findings more useful in regional and alternative production systems. Still, veterinary professionals will want more than encouraging performance data. They’ll need clarity on dose consistency, effects on flock health under commercial stressors, residue and safety considerations, batch-to-batch variation in by-product inputs, and whether fermentation reliably reduces any anti-nutritional concerns associated with coffee pulp.

What to watch: Expect the next phase of work to focus on repeatability in larger commercial settings, standardization of fermentation methods, economics, and comparisons with other phytogenic or post-antibiotic feed strategies. If the data continue to hold up, fermented coffee cherry pulp could become one more example of a circular agriculture ingredient that appeals both to nutrition programs and to sustainability-minded supply chains.
