Cinnamon as a Natural Feed Additive: A Promising Alternative for Poultry Health and Performance
The poultry industry has entered a transformative era, where the emphasis on antibiotic-free production, food safety, and sustainable growth is more prominent than ever. In this context, phytogenic feed additives (PFAs) have garnered significant attention as natural and effective alternatives to antibiotic growth promoters (AGPs). Among these, cinnamon (Cinnamomum spp.) has emerged as a particularly promising candidate due to its well-documented bioactive properties.
The Need for Alternatives to AGPs
With the increasing global concerns regarding antimicrobial resistance and the presence of antibiotic residues in animal-derived products, many countries have restricted or banned the use of AGPs in poultry production. This paradigm shift has driven extensive research into plant-based compounds that can support poultry health and productivity without compromising food safety. To understand the history behind this shift, read our blog on Antibiotic Resistance in the Poultry Industry: History & Background.
Phytochemistry and Functional Properties of Cinnamon
Cinnamon contains a rich array of bioactive compounds, including:
- Cinnamaldehyde
- Eugenol
- Polyphenols (e.g., proanthocyanidins and flavonoids)
- Terpenoids and tannins
These compounds exhibit antioxidant, antimicrobial, anti-inflammatory, and digestive stimulant properties. The essential oils derived from cinnamon bark and leaves are particularly potent in modulating gut health and overall physiological functions in poultry.

Comparison: Ceylon Cinnamon vs. Cassia Cinnamon for Poultry Feed Additive Use
| Feature | Ceylon Cinnamon (C. verum) | Cassia Cinnamon (C. cassia, C. burmanni, etc.) |
| Common Name | True Cinnamon, Sri Lankan Cinnamon | Chinese, Indonesian, or Saigon Cinnamon |
| Coumarin Content | Very low (<0.004%) — safer for long-term use | High (up to 5%) — hepatotoxic at high doses |
| Cinnamaldehyde Content | Moderate (~50–65%) — balanced antimicrobial profile | Higher (~70–80%) — more aggressive but can irritate tissues |
| Eugenol Content | Higher — contributes to anti-inflammatory & antioxidant effects | Lower |
| Taste & Aroma (Indicator of Purity) | Mild, sweet, refined — indicates low toxin load | Strong, pungent, bitter |
| Safety Profile | Ideal for continuous feeding — low toxicity risk | Requires caution — high coumarin limits prolonged use |
| Polyphenol Diversity | Broader spectrum — includes more tannins, flavonoids | Narrower polyphenol profile |
| Scientific Preference | Preferred in research for long-term health modulation | Used more in bulk due to cost |
| Cost | Higher — due to manual harvesting and purity | Lower — mass-produced |
| Regulatory & Consumer Acceptance | High — safe, premium quality, no residue concerns | Lower — risk of consumer pushback due to coumarin toxicity |
Why Ceylon Cinnamon Is Better for Poultry Feed Applications
- Safer for prolonged inclusion in diets due to minimal coumarin
- Rich in antioxidants and immune-boosting compounds (eugenol, proanthocyanidins)
- Gentler on the gut — suitable for chicks, layers, and broilers
- Delivers consistent results in microbiota modulation and stress resistance
- Aligns with premium antibiotic-free and residue-free poultry programs
Documented Benefits in Poultry Production
Numerous peer-reviewed studies have highlighted the multifaceted benefits of dietary cinnamon supplementation in poultry:
- Improved Gut Health
Cinnamon promotes a favorable gut microbiota by enhancing the population of beneficial bacteria (Lactobacillus spp., Bifidobacterium spp.) and suppressing pathogenic species such as E. coli, Clostridium spp., and Salmonella spp. Learn how enzymes can further enhance gut health and feed efficiency in our blog on Enzymes in Poultry Nutrition: Enhancing Efficiency and Sustainability. - Enhanced Nutrient Digestibility
Cinnamon essential oils stimulate the secretion of digestive enzymes and protect intestinal villi from oxidative stress, thereby improving nutrient absorption and feed conversion ratio (FCR). - Immunomodulatory Effects
Cinnamon influences cytokine expression and reduces oxidative biomarkers, thereby enhancing the birds’ immune responses and resilience to stressors, including heat stress and pathogen exposure. - Favorable Blood Biochemistry
Studies have shown reduced serum cholesterol, LDL, and triglyceride levels in cinnamon-fed birds, along with increased antioxidant enzyme activity and immunoglobulin levels. - Gene Expression and Inflammatory Modulation
Cinnamon bioactives downregulate pro-inflammatory pathways (e.g., NF-κβ) and upregulate protective genes, contributing to reduced intestinal inflammation and better health outcomes.
Applications and Dosage
Cinnamon can be administered in various forms—powder, essential oil, or in combination with other phytogenic substances. Typical inclusion rates in broiler diets range between 100 mg/kg to 500 mg/kg, depending on the formulation and production goals.
Conclusion
Cinnamon represents a scientifically supported, natural solution to many of the challenges currently faced in poultry production. Its integration as a feed additive aligns with the industry’s goals of reducing antibiotic dependency, improving animal welfare, and producing safe, high-quality poultry products. Continued research and development into standardized cinnamon-based formulations may further enhance its efficacy and adoption across global markets.
