Researchers tested whether a natural substance called ferulic acid could help chickens grow faster and maintain healthier fat levels. They fed 640 young chickens different amounts of this plant-based compound for six weeks. The results showed that chickens receiving ferulic acid gained weight faster and had better cholesterol and fat levels in their bodies. The compound worked by turning on special proteins in the chickens’ livers that help control how their bodies process and store fat. This discovery could help farmers raise healthier chickens more naturally, without relying only on medications or special feed additives.

The Quick Take

  • What they studied: Whether adding a natural plant compound called ferulic acid to chicken feed would help them grow better and maintain healthier fat and cholesterol levels
  • Who participated: 640 male baby chickens (broilers) that were divided into five groups and fed different amounts of ferulic acid for 42 days
  • Key finding: Chickens that received ferulic acid grew faster and had significantly lower levels of harmful fats and cholesterol in their livers compared to chickens that didn’t receive it
  • What it means for you: If you raise chickens or eat chicken, this suggests that ferulic acid could be a natural way to produce healthier birds. However, this research was done on chickens, so results may not directly apply to humans, and more research is needed before widespread use

The Research Details

Scientists divided 640 young male chickens into five equal groups when they were just one day old. Each group received the same basic diet, but with different amounts of ferulic acid added—some got none (the control group), while others got 50, 100, 150, or 200 milligrams per kilogram of feed. All chickens ate their assigned diet for 42 days (about six weeks), which is the typical time it takes to raise chickens for meat. The researchers then measured how much weight the chickens gained, checked their liver health, and examined the bacteria living in their digestive systems.

Ferulic acid is a natural compound found in plants like rice bran, oats, and coffee. Scientists chose to study it because previous research suggested it might help control how bodies process and store fat. By testing five different amounts, the researchers could figure out which dose worked best without causing problems.

This type of study is called a controlled experiment because the researchers carefully controlled everything except the amount of ferulic acid, allowing them to see if the acid itself made the difference in the chickens’ health.

This research approach is important because it tests a natural alternative to chemical additives that farmers currently use. By using a large number of chickens (640) and carefully measuring multiple health markers, the researchers could see real effects that might work in actual farms. Understanding how ferulic acid affects the body’s fat-processing systems helps scientists develop better, more natural ways to keep farm animals healthy and reduce disease risk.

This study has several strengths: it used a large number of animals, tested multiple doses to find the best amount, and measured many different health markers rather than just one. The researchers also examined the bacteria in the chickens’ guts and used advanced testing to understand how the compound worked at a molecular level. However, because this is a chicken study, results may not directly apply to humans. The study was published in a peer-reviewed scientific journal, meaning other experts reviewed it before publication. The research was conducted recently (2026), so it reflects current scientific methods.

What the Results Show

Chickens that received ferulic acid grew noticeably faster than the control group, with the effect increasing as the dose increased. This means the more ferulic acid they received, the better they grew—up to a point.

When researchers examined the chickens’ livers at the end of the study, they found that ferulic acid significantly reduced three types of harmful fats: triglycerides (a common type of fat in the blood), total cholesterol, and LDL cholesterol (often called “bad” cholesterol). These improvements were dose-dependent, meaning higher amounts of ferulic acid produced greater improvements.

The researchers discovered that ferulic acid worked by activating special proteins in the liver called PPAR and AMPK. Think of these proteins like switches that control how the body breaks down and uses fat. When ferulic acid turned these switches on, the chickens’ bodies became better at managing fat, similar to how a more efficient engine uses fuel better.

Ferulic acid also increased bile acid levels in both the liver and bloodstream. Bile acids are important because they help the body digest fats and control cholesterol levels. Higher bile acid levels suggest the chickens’ bodies were processing fats more efficiently.

The study also examined the bacteria living in the chickens’ digestive systems. Ferulic acid changed the balance of these bacteria in beneficial ways—it increased helpful bacteria called Blautia and Eisenbergiella while decreasing potentially harmful bacteria like Enterococcus and Bacillus. A healthy gut bacteria balance is important for digestion and overall health. Advanced chemical analysis of the chickens’ digestive contents showed that ferulic acid affected pathways related to how the body processes fats and amino acids (building blocks of protein), suggesting the compound influences multiple systems in the body.

This research builds on earlier studies showing that ferulic acid has health benefits. Previous research in other animals and in laboratory studies suggested this compound could help control fat storage and improve metabolism. This chicken study is important because it tests these ideas in a living animal that’s actually raised for food, making the results more relevant to real farming. The findings align with what scientists expected based on how ferulic acid works at the molecular level, which strengthens confidence in the results.

This study was conducted only in chickens, so we cannot assume the same results would occur in humans or other animals without further research. The study measured short-term effects (42 days), so we don’t know if benefits would continue long-term or if the chickens’ bodies might adapt over time. The researchers didn’t test whether ferulic acid affects the taste or quality of the chicken meat itself. Additionally, while the study identified that ferulic acid activates certain proteins, it didn’t fully explain all the ways this compound works in the body. Finally, this research was funded and conducted by scientists with expertise in this area, but independent confirmation from other research groups would strengthen the findings.

The Bottom Line

Based on this research, ferulic acid at a dose of 100 milligrams per kilogram of feed appears to be the optimal amount for chickens, producing the best balance of growth improvement and health benefits. This recommendation has moderate confidence because it comes from a well-designed study with a large number of animals, but it’s specific to chickens and hasn’t been tested in humans. Farmers interested in using ferulic acid should consult with veterinarians and consider their specific situation before making changes.

Chicken farmers and poultry producers should pay attention to this research as a potential natural way to improve bird health and growth. People interested in more natural food production methods may find this relevant. However, consumers should not assume they need to take ferulic acid supplements based on this chicken research—human studies would be needed to determine if similar benefits apply to people. People with existing health conditions should consult doctors before making dietary changes based on animal research.

In chickens, the benefits appeared within the 42-day study period, with growth improvements visible throughout the six weeks. If similar compounds were tested in humans, benefits would likely take weeks to months to become noticeable, and long-term studies would be needed to confirm safety and effectiveness. Realistic expectations would be gradual improvements rather than immediate changes.

Want to Apply This Research?

  • If tracking dietary supplements or natural compounds, users could log ferulic acid intake (if they choose to use it) and monitor energy levels, digestion quality, and weight changes weekly. Track metrics like energy throughout the day (1-10 scale), digestive comfort, and any changes in cholesterol levels if they have recent blood work.
  • Users interested in supporting healthy fat metabolism could incorporate ferulic acid-rich foods into their diet, such as brown rice, oats, coffee, and whole grains. They could set a goal to eat one serving of these foods daily and track their consumption in the app while monitoring how they feel.
  • Establish a monthly check-in system to review energy levels, weight trends, and digestive health. If users are taking supplements, they should track consistency of use and any noticeable changes in how they feel. For those interested in cholesterol management, schedule regular blood work every 3-6 months and compare results over time to see if dietary changes correlate with improvements.

This research was conducted in chickens and does not directly prove that ferulic acid will have the same effects in humans.
