Rosemary (Rosmarinus officinalis) is a proven feed additive packed with natural compounds like carnosic acid and rosmarinic acid. Rosemary has been shown in peer-reviewed research to support better egg quality, immune strength, and digestive function in laying hens.
Increase egg production and improve egg quality including shell thickness, yolk weight, albumen height, and Haugh unit (a key measure of egg freshness).
Boost immune response by enhancing antibody levels (IgA, IgM) and increasing disease resistance, shown to rival antibiotic performance in some studies.
Improve antioxidant status by raising natural defense enzymes like SOD (superoxide dismutase) and catalase, reducing oxidative stress in hens.
Enhance gut health and digestion, improving nutrient absorption and reducing gut inflammation for more efficient feed conversion.
Protect against harmful bacteria like E. coli and Salmonella, while lowering inflammation markers like IL-6 in older or stressed hens.
Support respiratory and metabolic health, helping birds cope with environmental stress and maintain better oxygenation and circulation.
At Buff Clucks, we don’t add ingredients just because they sound good...we add them because they work.
That’s why rosemary earned its place in every bag of Buff Clucks Herb Supplement. Studies show that rosemary helps hens lay stronger eggs, fight off illness, and digest their food more efficiently. It’s packed with powerful natural compounds that strengthen immunity, reduce stress, and even protect against bacteria like E. coli and Salmonella.
In simple terms, rosemary keeps your flock healthier, happier, and more productive. All from a natural herb backed by science. That’s the Buff Clucks Herb Supplement difference: smarter, nature-powered nutrition your chickens can truly thrive on.

In a 2023 peer-reviewed study conducted in Ethiopia and the UK, researchers evaluated the impact of supplementing laying hens’ diets with 5.2% dried rosemary leaf meal. The findings were significant showing measurable improvements in egg production, feed efficiency, and overall laying performance.
Hen-day egg production rose to 79% in hens fed 5.2% rosemary leaf meal, a significant increase over the control group. More hens laid eggs consistently, showing rosemary’s impact on laying performance.
Feed conversion ratio (FCR) improved, meaning hens used less feed to produce more eggs. Rosemary helped optimize nutrient absorption, improving efficiency for both backyard and commercial flocks.
Hens receiving rosemary produced a greater total egg mass and laid more eggs overall during the trial. This demonstrates not just more frequent laying, but improved overall productivity per bird.
We’ve all wondered what makes some hens lay better than others. For us, the answer came straight from nature and research.
When we discovered that rosemary could help hens lay up to 79% more eggs, we knew it belonged in Buff Clucks Herb Supplement. Science shows that even a small dose helps chickens use feed more efficiently, turning nutrients into stronger, more consistent eggs. We’ve seen it firsthand, flocks that once slowed down are now thriving.
The reason why we made rosemary a core ingredient in Buff Clucks Herb Supplement. It’s our way of helping every flock owner see what happens when real science meets real results.

Multiple studies show rosemary can do more than flavor feed. It helps chickens stay healthier by boosting natural immunity. It increases key antibodies, calms inflammation, and supports the gut’s protective barrier. Even better, rosemary’s immune effects have rivaled antibiotics in trials. It's safe, natural, and science-backed.
Rosemary increases immunoglobulins like IgA and IgM, which strengthen mucosal and systemic defenses, vital for preventing infections in the gut and respiratory tract.
It enhances the activity of superoxide dismutase (SOD), a key antioxidant that protects cells from free radical damage and oxidative stress.
Rosemary-fed birds showed significantly lower levels of interleukin-6 (IL-6), a major pro-inflammatory cytokine. Lower inflammation = healthier, calmer birds.
Rosemary improves the expression of gut barrier proteins and immune-related genes, helping birds better absorb nutrients and defend against pathogens.
At Buff Clucks we believe healthy flocks don’t just happen by luck, they happen with the right support. That’s why rosemary earned its place in every bag of Buff Clucks Herb Supplement.
Studies show it strengthens a chicken’s natural defenses from the inside out, boosting antibodies, calming inflammation, and protecting against stress.
We like to think of rosemary as your hens’ built-in wellness booster, helping them live stronger, longer, and naturally better.

Rosemary reduces spoilage, enhances taste, and improves shelf life. It also improves the quality, safety, and shelf life of poultry meat after processing. Thanks to its potent antioxidant and antimicrobial compounds, rosemary acts as a natural preservative, protecting meat from oxidation and bacterial growth.
After seeing what rosemary can do, it’s easy to understand why farmers have trusted it for centuries and why science now backs it up. Rosemary naturally protects meat from spoilage, improves flavor, and keeps bacteria like E. coli and Salmonella in check.

Rosemary-fed birds had significantly lower malondialdehyde (MDA) concentrations in their meat. MDA is a marker of spoilage and rancidity meaning rosemary helps keep meat fresher and more stable for longer.
Rosemary’s antimicrobial properties helped lower bacterial contamination, making meat safer for consumption without artificial preservatives.
By preserving meat quality naturally, rosemary offers a clean-label alternative to synthetic preservatives, ideal for those raising poultry for personal use or local markets.
