A 2026 study of 360 chickens found that a microencapsulated blend of organic acids and cinnamon significantly improved growth and feed efficiency when added at 3.0 grams per kilogram of feed, with chickens gaining more weight and requiring less feed per pound of growth. According to Gram Research analysis, the supplement worked by improving intestinal structure and nutrient absorption, offering a natural alternative to antibiotic growth promoters in poultry farming.
According to Gram Research analysis, scientists tested a new natural supplement made from organic acids and cinnamon to help chickens grow faster and healthier without using antibiotics. They gave the supplement to 360 baby chickens at different doses and compared them to chickens that got antibiotics or no supplement. The results showed that chickens receiving the highest dose of the supplement gained more weight and converted their feed into body mass more efficiently. The supplement also improved how well the chickens’ intestines absorbed nutrients like protein and calcium. This research suggests that farmers might have a natural alternative to antibiotics for raising healthier, faster-growing chickens.
Key Statistics
A 2026 research article studying 360 broiler chickens found that the 3.0 g/kg dose of microencapsulated organic acids-cinnamon supplement significantly increased body weight gain and improved cumulative feed conversion ratio compared to control groups.
In a 360-chicken study published in 2026, the 3.0 g/kg supplement dose significantly expanded villus surface area in the small intestine and increased crude protein and calcium digestibility, explaining improved growth performance.
A 2026 poultry study of 360 chickens found that the 1.5 g/kg dose of the organic acids-cinnamon blend achieved the highest villus height to crypt depth ratio, indicating optimal intestinal health improvements.
Research on 360 broiler chickens in 2026 demonstrated that the microencapsulated organic acids-cinnamon supplement improved phosphorus digestibility at the 1.5 g/kg dose and ash digestibility at both supplement levels tested.
The Quick Take
- What they studied: Whether a natural blend of organic acids and cinnamon extract could help chickens grow better and stay healthier, similar to how antibiotics work as growth promoters
- Who participated: 360 newborn male Ross 308 chickens (a common breed used in chicken farming) divided into four groups receiving different treatments over their growth period
- Key finding: Chickens given the highest dose (3.0 grams per kilogram of feed) gained significantly more weight and needed less feed to gain each pound of body weight compared to control groups
- What it means for you: If you eat chicken, this research suggests farmers may soon have a natural, antibiotic-free way to raise healthier birds. However, this study was done in a controlled lab setting, so results on real farms may vary
The Research Details
Researchers divided 360 baby chickens into four equal groups. One group got regular feed with no additives (negative control), one group got feed with antibiotics (positive control), and two groups got feed mixed with the organic acids-cinnamon supplement at two different amounts: 1.5 grams and 3.0 grams per kilogram of feed. All chickens were raised under identical conditions and monitored throughout their growth period.
The scientists measured multiple things to understand how well the supplement worked. They tracked how much weight each chicken gained, how much feed they ate, and how efficiently they converted feed into body weight. They also examined the chickens’ intestines under a microscope to see if the supplement changed the structure of the intestinal lining, which is important for nutrient absorption.
Additionally, researchers tested blood samples to check immune function and antioxidant levels—these are natural chemicals that protect cells from damage. They also measured how well the chickens’ intestines absorbed important nutrients like protein, calcium, and phosphorus.
This research approach is important because it tests a natural alternative to antibiotics in a controlled setting where scientists can measure exactly what happens. By looking at both growth performance and intestinal health, the study shows not just that the supplement works, but how it works—through improved intestine structure and better nutrient absorption. This gives farmers and the poultry industry confidence that the supplement could work in real-world farming situations.
This study was published in Poultry Science, a respected journal in animal agriculture. The researchers used a large sample size (360 chickens) divided into multiple groups, which strengthens the reliability of the findings. They measured many different outcomes rather than just one, giving a complete picture of the supplement’s effects. However, this was a controlled laboratory study, so results may differ in real farm conditions with different environments and management practices
What the Results Show
The most important finding was that chickens receiving 3.0 grams of the organic acids-cinnamon supplement per kilogram of feed gained significantly more weight than control chickens. This dose also improved feed conversion ratio, meaning the chickens needed less feed to gain the same amount of weight—a key measure of efficiency in poultry farming.
When researchers examined the chickens’ intestines, they found that the supplement changed the structure of the intestinal lining in beneficial ways. Specifically, the 3.0 gram dose significantly increased the surface area of the intestinal villi (tiny finger-like projections that absorb nutrients). The 1.5 gram dose produced the best ratio of villus height to crypt depth, which indicates healthier intestinal tissue.
The supplement also improved how well chickens absorbed important nutrients. At the 3.0 gram dose, chickens showed significantly better absorption of crude protein and calcium. At the 1.5 gram dose, phosphorus absorption was optimized. These improvements in nutrient absorption likely explain why the chickens grew better—their bodies were getting more nutrition from the same amount of feed.
Interestingly, the supplement did not significantly affect feed intake, immune response to Newcastle disease virus, or antioxidant levels in the blood. This suggests the supplement works primarily by improving intestinal health and nutrient absorption rather than by boosting immunity or reducing cellular damage.
The study found that ash (mineral content) digestibility showed dose-dependent improvements, with both linear and quadratic responses to increasing supplement levels. This indicates that the organic acids and cinnamon work synergistically to help chickens absorb minerals more effectively. The fact that the 1.5 gram dose was optimal for phosphorus absorption while the 3.0 gram dose was better for protein and calcium suggests that different nutrients respond differently to the supplement at different doses.
This research builds on previous studies showing that organic acids and plant extracts like cinnamon can improve poultry performance. However, this study is unique because it combines both ingredients in a microencapsulated form (tiny protective capsules that release the ingredients in the right part of the intestine) and measures both growth performance and detailed intestinal health markers. The results align with the growing body of evidence that natural alternatives to antibiotics can be effective, addressing the global concern about antibiotic resistance in farm animals.
This study was conducted in a controlled laboratory environment, so results may not perfectly match what happens on real farms with different conditions, management practices, and stress factors. The study only tested one specific formulation of the supplement, so other combinations of organic acids and cinnamon might work differently. The research only measured outcomes up to the end of the growth period, so long-term effects are unknown. Additionally, the study did not measure the cost-effectiveness of the supplement compared to antibiotics, which is important for farmers deciding whether to use it. Finally, this study was done with one chicken breed (Ross 308), so results might differ with other breeds
The Bottom Line
Based on this research, the 3.0 gram per kilogram dose of the microencapsulated organic acids-cinnamon supplement appears most effective for improving chicken growth and feed efficiency. However, the 1.5 gram dose may be preferred if phosphorus absorption is a priority. These recommendations have moderate confidence because they come from a single controlled study and need validation on commercial farms. Farmers interested in reducing antibiotic use should consider this supplement as a potential alternative, but should also consult with poultry nutritionists and conduct small-scale trials before full implementation
Poultry farmers and the chicken industry should care about this research because it offers a natural alternative to antibiotics for promoting growth. Consumers concerned about antibiotic use in food production may appreciate knowing that such alternatives are being developed. Veterinarians and animal nutritionists should be aware of this option when advising farmers. However, backyard chicken keepers with small flocks may not find this supplement practical or cost-effective. People with cinnamon allergies should note that this supplement contains cinnamon extract
Based on the study design, the growth benefits appeared within the standard 6-week broiler growth period. Improvements in intestinal structure and nutrient absorption likely occurred gradually throughout the growth period rather than immediately. If farmers were to implement this supplement, they should expect to see measurable improvements in growth rates and feed efficiency within one production cycle (typically 6-7 weeks for broiler chickens). However, consistent results across multiple flocks and seasons would take longer to establish
