Research shows that adding Stress-BioMax (a supplement containing betaine, vitamin C, and plant extracts) to chicken drinking water significantly improves growth and health. According to Gram Research analysis, chickens receiving 0.50 milliliters per liter gained the most weight at 3082 grams and achieved the best feed efficiency at 1.62 ratio, while also showing improved blood chemistry, reduced stress hormones, and better antioxidant protection.
Researchers tested a new drinking water supplement called Stress-BioMax that contains betaine, vitamin C, and plant extracts on chickens raised for meat. According to Gram Research analysis, the supplement improved how fast the chickens grew, made their meat more valuable, and helped their bodies handle stress better. The best results came at a specific dose, where chickens gained more weight, converted feed more efficiently, and showed better blood chemistry and antioxidant protection. This finding could help farmers raise healthier chickens more efficiently.
Key Statistics
A 2026 research study found that broiler chickens receiving 0.50 milliliters per liter of Stress-BioMax supplement in drinking water gained 3082 grams of body weight with a feed conversion ratio of 1.62, representing significant improvements in growth performance compared to unsupplemented controls.
Research published in PLoS ONE in 2026 showed that Stress-BioMax supplementation reduced harmful cholesterol types (LDL and VLDL), triglycerides, blood sugar, and stress hormone cortisol levels in broiler chickens while increasing beneficial HDL cholesterol and thyroid hormone levels.
A 2026 study demonstrated that the optimal dose of Stress-BioMax for overall physiological health in broilers occurred between 0.62 to 0.66 milliliters per liter, with antioxidant capacity increasing and cellular damage markers decreasing across all supplemented groups.
Research in 2026 found that Stress-BioMax supplementation increased carcass and muscle yields while decreasing abdominal fat and organ percentages in broiler chickens, improving the quality and value of meat produced.
The Quick Take
- What they studied: Whether adding a supplement containing betaine, vitamin C, and herbal extracts to chicken drinking water improves growth, meat quality, and overall health
- Who participated: Broiler chickens (meat chickens) given different doses of the supplement in their drinking water, with a control group receiving no supplement
- Key finding: Chickens receiving 0.50 milliliters per liter of Stress-BioMax gained the most weight (3082 grams) and converted feed most efficiently (1.62 ratio), with improvements in blood chemistry, antioxidant protection, and stress hormone levels
- What it means for you: This research suggests the supplement could help farmers raise healthier, faster-growing chickens. However, this study was done on animals, not humans, so it does not directly apply to human nutrition or health.
The Research Details
Researchers divided chickens into groups and gave each group a different amount of Stress-BioMax supplement in their drinking water: none, a small amount, a medium amount, or a larger amount. They measured how much weight the chickens gained, how efficiently they used their food, what their meat looked like, and various markers in their blood that show health and stress levels. The researchers used statistical methods called principal component analysis and regression analysis to find the best dose and understand how the supplement worked at different levels.
This type of study is called a dose-response study because it tests multiple amounts of a substance to find which works best. By testing four different doses, the researchers could see if more supplement was always better, or if there was an optimal amount. They also looked at many different health markers at once, which gives a complete picture of how the supplement affected the chickens.
Testing multiple doses is important because more of something is not always better. By finding the optimal dose (0.50 mL/L), farmers could get the best results without wasting money on excess supplement. The study looked at many different health markers, which helps confirm that the supplement actually improved overall health and not just one narrow measure. Using advanced statistical methods like principal component analysis allowed researchers to see the overall burden of stress and health problems, rather than looking at individual markers in isolation.
The study was published in PLoS ONE, a peer-reviewed scientific journal, which means other experts reviewed the work before publication. The researchers tested multiple doses rather than just one, which strengthens the findings. However, the abstract does not specify the exact number of chickens studied, which would help readers understand how reliable the results are. The study was conducted on animals, not humans, so results may not directly apply to people. The study appears to be well-designed with multiple measurements and statistical analysis, but readers should note this was animal research.
What the Results Show
The supplement significantly improved how fast chickens grew and how efficiently they used their food. At the optimal dose of 0.50 milliliters per liter, chickens gained 3082 grams of body weight and had a feed conversion ratio of 1.62, meaning they needed only 1.62 kilograms of feed to gain 1 kilogram of weight. This was the best performance across all doses tested.
The supplement also improved the quality of the meat and reduced unwanted fat. Carcass yield (the amount of usable meat) and muscle yield increased, while abdominal fat and organ percentages decreased. This means farmers would get more valuable meat from each chicken.
Blood chemistry improved significantly. The supplement reduced harmful cholesterol types (LDL and VLDL), triglycerides, blood sugar, and stress hormones like cortisol. It increased beneficial cholesterol (HDL) and thyroid hormone levels. These changes suggest the chickens’ bodies were working more efficiently and experiencing less stress.
The supplement improved the chickens’ natural defense systems against cellular damage. Antioxidant capacity increased while malondialdehyde (a marker of cellular damage) decreased, showing better protection at the cellular level. Liver function improved, with reduced enzyme activity indicating less liver stress. The researchers found that the benefits increased as the dose went up to 0.50 mL/L, but the optimal dose for overall physiological health appeared to be between 0.62 to 0.66 mL/L based on their statistical analysis. This suggests there may be an even slightly better dose than the one showing the best weight gain.
This study builds on previous research showing that betaine and vitamin C can help animals handle stress and improve growth. The addition of herbal extracts (phytogenic compounds) represents a newer approach combining multiple ingredients. The finding that an optimal dose exists, rather than more being always better, aligns with how many supplements work in animal nutrition. The improvement in both growth performance and antioxidant status simultaneously is notable, as these benefits often require trade-offs in other studies.
The study abstract does not specify the exact number of chickens tested, making it difficult to assess statistical power. The research was conducted only on broiler chickens, so results may not apply to other poultry or animals. The study does not appear to include long-term follow-up data or information about how the supplement affects chickens later in life. The mechanism of how the supplement works is not fully explained. Additionally, this is animal research, so direct application to human health is not appropriate without further human studies.
The Bottom Line
For poultry farmers: The research suggests using 0.50 milliliters per liter of Stress-BioMax in drinking water may improve chicken growth and meat quality. However, farmers should consult with their veterinarian or nutritionist before implementing changes, as individual farm conditions vary. The evidence is strong for broiler chickens but has not been tested in other contexts. For consumers: This research does not directly apply to human nutrition, as it was conducted on chickens. Do not assume this supplement would have the same effects in people.
Poultry farmers and producers interested in improving broiler chicken growth and meat quality should pay attention to this research. Veterinarians and animal nutritionists may find this useful for advising clients. Feed manufacturers might consider this for product development. General consumers should not assume these results apply to human health or use this supplement based on animal research alone.
In chickens, the improvements in growth and feed efficiency appeared during the normal growing period (the study does not specify exact timeline, but broilers typically grow for 6 to 7 weeks). Blood chemistry and antioxidant improvements likely occurred throughout the growing period. Farmers would see results within a single production cycle.
