Researchers tested whether catechu powder, a natural plant extract, could help protect chicken intestines from harmful bacterial toxins. They fed some chickens regular food and others food mixed with catechu powder, then exposed both groups to a substance that causes gut inflammation. Chickens eating the catechu powder had less inflammation, less cellular damage from harmful molecules, and healthier intestinal linings. This suggests catechu powder could be a natural alternative to antibiotics in chicken farming, helping keep birds healthy while reducing antibiotic use.

The Quick Take

  • What they studied: Whether adding catechu powder (a natural plant extract) to chicken feed could protect their intestines from damage caused by bacterial toxins.
  • Who participated: 100 one-day-old broiler chickens divided into two groups: one eating regular feed and one eating feed with catechu powder added. The chickens were split into smaller groups to test different conditions.
  • Key finding: Chickens that ate catechu powder had significantly less intestinal inflammation (up to 78% reduction in harmful inflammatory signals), less cellular damage (up to 54% reduction), and healthier gut linings when exposed to bacterial toxins compared to chickens without the supplement.
  • What it means for you: This research suggests catechu powder could help reduce the need for antibiotics in chicken farming. While this study was done in chickens, it points to a natural way to keep poultry healthy. However, more research is needed before this could be used in human food or supplements.

The Research Details

Scientists divided 100 young broiler chickens into two main groups: one fed normal chicken feed and one fed chicken feed mixed with catechu powder (a plant extract). Within each group, they further divided the chickens so that some received an injection of lipopolysaccharide (a substance from bacteria that causes gut inflammation) and others received a harmless salt solution as a control. This created four different test conditions to see how catechu powder affected the chickens’ response to the bacterial toxin.

After 27 days of feeding, the researchers measured how well the chickens grew. Then on day 29, they gave the injections and collected samples from the chickens’ blood and intestines three hours later. They measured levels of inflammatory chemicals, harmful molecules that damage cells, and looked at the structure of the intestinal tissue under a microscope.

The researchers used statistical tests to determine whether the differences they found were real and not just due to chance. They specifically looked for interactions between the catechu powder and the bacterial toxin challenge to see if the supplement helped protect against the toxin’s harmful effects.

This research design is important because it tests catechu powder under stress conditions (bacterial toxin exposure) rather than just in normal, healthy chickens. This mimics what happens in real farming situations where chickens might be exposed to harmful bacteria. By comparing treated and untreated chickens side-by-side under the same conditions, the researchers could clearly see whether catechu powder actually provided protection.

The study used a controlled experimental design with multiple replicates (repeated groups), which strengthens the reliability of the results. The researchers measured multiple different outcomes (inflammation markers, oxidative stress, intestinal structure, and barrier function genes), which provides a more complete picture. However, this study was conducted only in chickens, so results may not directly apply to other animals or humans. The study was published in a peer-reviewed journal, meaning other scientists reviewed it before publication. The sample size of 100 chickens is reasonable for this type of animal research.

What the Results Show

When chickens were exposed to the bacterial toxin, those eating catechu powder showed dramatically lower levels of inflammatory chemicals. Specifically, they had 37% less of a chemical called interferon-gamma in their upper intestines, 31% less of a chemical called tumor necrosis factor-alpha in the same area, and 24% less interferon-gamma in their middle intestines. In the blood, the reductions were even more dramatic: 70% less interleukin-8 and 78% less tumor necrosis factor-alpha.

The catechu powder also protected against cellular damage caused by harmful molecules called free radicals. In the blood, chickens eating catechu powder had 53% less hydrogen peroxide and 30% less malondialdehyde (a marker of cellular damage). In their intestines, the reductions were 54% for hydrogen peroxide in the upper intestines and 39% for malondialdehyde in the middle intestines.

Perhaps most importantly, catechu powder helped maintain the physical structure and function of the intestinal barrier. The finger-like projections in the intestines (called villi) that absorb nutrients were 24% taller in chickens eating catechu powder. The chickens also had 52% higher levels of a protein called Claudin1 and 123% higher levels of a protein called Mucin2, both of which are essential for maintaining a healthy intestinal barrier that prevents harmful substances from entering the bloodstream.

The study also measured general growth performance in the chickens, though specific growth data wasn’t highlighted in the abstract. The fact that multiple different protective mechanisms were activated (reduced inflammation, reduced oxidative stress, and improved barrier structure) suggests that catechu powder works through several different pathways rather than just one. This multi-targeted approach may make it more effective than single-action treatments.

This research builds on previous knowledge that plant-based polyphenols (natural compounds found in plants) have anti-inflammatory and antioxidant properties. The novelty here is demonstrating that catechu powder specifically can protect poultry intestines during a bacterial challenge. As antibiotic resistance becomes a growing concern in farming, finding natural alternatives has become increasingly important. This study provides evidence that catechu powder could be one such alternative, though more research comparing it directly to other natural additives would be helpful.

This study was conducted only in chickens, so the results may not apply to other animals or humans. The researchers only tested one dose of catechu powder (1,000 mg per kilogram of feed), so it’s unclear whether higher or lower doses might be more or less effective. The study measured effects only 3 hours after the bacterial toxin injection, so longer-term effects are unknown. The study didn’t compare catechu powder to antibiotics directly, so we can’t say whether it works as well as or better than current antibiotic treatments. Finally, this was a controlled laboratory study, so results in real farming conditions with multiple stressors might be different.

The Bottom Line

Based on this research, catechu powder appears promising as a natural feed additive for poultry to support intestinal health during bacterial challenges. However, this is early-stage research in animals, and more studies are needed before it could be recommended for human use or before it could replace antibiotics in farming. If you’re involved in poultry farming, discussing catechu powder with a veterinarian would be appropriate, though it’s not yet an established standard practice.

Poultry farmers and the agricultural industry should pay attention to this research as they seek alternatives to antibiotics. Consumers concerned about antibiotic use in food production may find this encouraging. Researchers studying natural alternatives to antibiotics should note these findings. However, this research does not yet apply to human health or nutrition, so general consumers shouldn’t expect to use catechu powder as a health supplement based on this study alone.

In this study, protective effects were observed within 3 hours of bacterial exposure in chickens already eating catechu powder for 27-29 days. This suggests that the supplement needs to be given before exposure to be effective. In a real farming scenario, benefits might take weeks to become apparent in terms of overall bird health and growth. Long-term effects beyond 3 hours are unknown from this study.

Want to Apply This Research?

  • For poultry farmers using this research: Track daily feed consumption (grams per bird), weekly weight gain, and any signs of intestinal distress (diarrhea, reduced appetite) to monitor whether catechu powder supplementation improves overall flock health compared to baseline.
  • If implementing catechu powder supplementation: Start by mixing the powder into feed at the recommended dose (1,000 mg/kg), maintain consistent feeding schedules, and monitor bird behavior and health indicators daily. Document any changes in feed efficiency or health outcomes.
  • Establish a baseline of flock health metrics (weight gain, feed conversion, disease incidence) for 2-4 weeks before adding catechu powder, then continue tracking the same metrics for 8-12 weeks after supplementation begins. Compare results to identify any improvements in intestinal health indicators and overall productivity.

This research was conducted in chickens and does not directly apply to human health or nutrition. Catechu powder is not currently approved as a human dietary supplement or medicine. Anyone considering catechu powder for any purpose should consult with a healthcare provider or veterinarian. This study is early-stage research and should not be used as the sole basis for making farming or health decisions. Always follow local regulations regarding feed additives and consult with agricultural extension services or veterinarians before implementing new feeding practices.
