Garlic, Turmeric & Curcumin: Natural Support in Poultry Health

There has been a great deal written over the years about the benefits of natural medicinal substances. Some people believe strongly in them. Others dismiss them entirely. The truth, as usual, is found in understanding how these substances work, where they may be useful, and where their limitations are.

Natural compounds have not always been embraced by modern medicine, especially in animal health. In many cases, they have been overlooked or dismissed as having little value in disease support. That is beginning to change. As researchers continue to study natural medicinal supplements, more information is becoming available about how these compounds may support poultry health.

One of the driving forces behind this research is the growing concern over antibiotic resistance. There is increasing interest in reducing unnecessary antibiotic use in both animals and humans. With that concern has come more research into natural compounds that may help support health, immune function, and disease resistance.

Garlic and Allicin

Most people are familiar with garlic, but fewer understand what makes garlic useful as a medicinal compound.

The active compound associated with garlic is called allicin. Interestingly, allicin is not actually present in whole garlic until the garlic is crushed or smashed. When garlic is crushed, it releases the enzyme alliinase. That enzyme combines with alliin and converts it into allicin.

Only after that reaction takes place does garlic develop many of the properties people associate with it, including antiviral, antibacterial, antifungal, and antiprotozoal activity.

Allicin is a powerful compound, but it is also highly unstable. Once produced, it does not last long in the environment. Because of that instability, garlic products intended for medicinal use must be prepared carefully.

Stabilized Allicin

The usefulness of allicin depends heavily on stabilization. Dr. Peter Josling introduced a patented water extraction process that stabilizes allicin and allows it to be used in powdered form for oral consumption and gel form for topical applications.

For poultry, a reasonable starting point for garlic powder in the diet is approximately one half percent of the total feed ration being offered.

Turmeric: An Ancient Medicinal Plant

Turmeric has been used for food, medicine, coloring, and other purposes for nearly four thousand years. It has long been used as a spice and as a dietary aid, especially in India and Southeast Asia.

Turmeric is best known as a deep yellow to yellow-orange powder. It comes from Curcuma longa, a member of the ginger family. Turmeric is a rhizome, meaning the plant’s stems grow underground.

India is one of the largest producers of turmeric and also consumes a large portion of what it produces.

Understanding Curcumin

To understand curcumin, we first have to understand turmeric.

Curcumin is the primary active compound found in turmeric. Turmeric typically contains about four percent curcumin, which means concentrated curcumin can be expensive to produce in quantities used for medicinal purposes.

Turmeric and curcumin have been studied extensively over the last several decades. Thousands of articles have been published on their potential benefits. Although turmeric has been used traditionally for thousands of years, many of the specific benefits of curcumin have only been studied more closely in modern research.

Curcumin’s Potential Benefits

Curcumin has a wide range of properties that may be beneficial, including:

• Antioxidant activity

• Anti-inflammatory activity

• Chemopreventive activity

• Chemotherapeutic activity

• Free radical scavenging properties

• Support for cellular signaling pathways

Curcumin has also been associated with apoptosis, or programmed cell death. One of the interesting areas of study is curcumin’s ability to affect abnormal cells differently than healthy cells. The exact mechanisms are still being researched, but this may be related to the multiple pathways curcumin uses inside the body’s cells.

Curcumin, Bioavailability & Black Pepper Extract

In its natural state, curcumin has poor bioavailability. Bioavailability refers to how much of a substance is absorbed into the bloodstream and becomes available for use in the body.

Substances given intravenously generally have very high bioavailability. Substances given orally often have much lower bioavailability because they must pass through the digestive system before absorption.

Understanding bioavailability is important when working with natural products. A product cannot be beneficial if the body cannot absorb enough of it.

Curcumin and turmeric work better when potentiated with BioPerine, a patented extract of black peppercorn. BioPerine may increase the bioavailability of curcumin significantly compared with a non-potentiated product. This improvement in absorption has helped increase curcumin’s overall usefulness.

Curcumin in Poultry Feed

Research using curcumin in growing chickens has shown tremendous potential for poultry health.

The addition of curcumin to the diet of growing birds has been associated with increased production of intestinal mucin. Mucin is a gel-like material that helps protect the epithelial surface of the intestinal tract. It is one of the bird’s first lines of intestinal defense against potential pathogens.

Greater mucin production may provide stronger intestinal protection. It may also help stimulate immune function by supporting the goblet cells responsible for producing mucin.

Further studies have shown that birds receiving curcumin in the diet may produce more immune cells than birds that do not receive curcumin.

Because curcumin may act as an intestinal stimulant, growing birds fed a diet containing curcumin may also show improved weight gain compared with birds that do not receive curcumin.

Clinical Observations with Curcumin

My personal experience with curcumin in the office has been positive in many cases.

These observations were not double-blind studies, so they should be understood as clinical experience rather than controlled research. However, based on cause and effect and the symptoms presented, curcumin appeared helpful in a number of cases.

Birds that presented with symptoms consistent with Marek’s disease, based on age and physical symptoms, were given curcumin daily. Positive results were observed in many cases. Approximately forty percent of the perceived Marek’s disease cases did not show a positive outcome.

In the birds that responded, the response was often fairly quick. Birds that did not respond generally did not respond at all. It is possible that longer-term administration may have provided better results in some non-responders, and there is literature suggesting that long-term use of curcumin may improve outcomes in certain cases.

Overall, my experience with this natural medicinal supplement has been quite positive, and I will continue to suggest its use in poultry for a variety of health problems where appropriate.

Final Thoughts

Whether garlic, turmeric, or curcumin become mainstream components of poultry rations will depend on availability, cost, and measurable results.

These natural compounds should not be viewed as magic cures. They are tools. Like any tool, they must be understood, used correctly, and matched to the situation.

For poultry keepers, the future of natural medicinal support is worth paying attention to, especially as the industry continues to look for ways to support bird health while reducing unnecessary antibiotic use.

Until next time, keep ’em healthy.
