Essential Oils: Helping Your Birds Live Their Best Lives

While there is still skepticism around the use of essential oils and more research to bespring chicken bantam hen conducted, some poultry farmers have integrated essential oils and other natural ingredients into their birds’ diets to promote flock health. Let’s look at these amazing natural compounds and how they can help your birds live their best lives.

What are essential oils?

Essential oils are plant products are distilled from leaves, flowers, stems, and roots and can be combined with a carrier oil or other liquid. They can also be used in dried form. In humans, essential oils are used as liniments (external) or infusions (internal/external).

Essential Oils and Chickens

Some backyard chicken owners regularly use herbs such as oregano, thyme, and rosemary because they believe they have antimicrobial, astringent, and antifungal properties, as well as the ability to repel insects. Essential oils from these plants are also making their way into chicken feeds.    

Essential oils are part of a class of plant extracts called phytogenics (FY-toh-JEN-ihks). Poultry farmers are starting to use phytogenics, including essential oils, in their feeds to prevent disease. They are also using phytogenics in feeds to support healthy growth. Proprietary research has shown that essential oils benefit the digestive, reproductive, and immune systems in laying hens. The following are a few examples of essential oils and their benefits. 

Oregano

oreganoStudies show that oregano oil extracted from two species, Origanum vulgare and Thymus capitatus, have antimicrobial and antiparasitic properties. However, these oregano species are not sold in traditional grocery stores, so finding a source of the right varieties is important. 

 

Rosemary

A member of the evergreen family, this common medicinal plant can protect poultry livers from toxic molds. Other benefits to chickens include high levels of vitamins A, C, and B, as well as magnesium, calcium, copper, iron, and manganese. Rosemary also contains carnosic acid, which protects the nervous system and promotes healing in the brain. It can be used to prevent (not cure) certain bacterial infections, such as Staphylococcus aureus, which causes bumblefoot.[1] Its strong smell also acts as an insect repellent.

Thyme

thymeThis member of the mint family is a medicinal herb in many cultures. In poultry it acts as an antioxidant that protects the intestine and boosts the immune system. As a hygienic environmental spray, it also has antibacterial properties, decreasing the number of Coliform bacteria. Other effects in poultry include improvement in growth and digestive and antioxidant enzymes.[2]   

Star Anise

Star anise is the seed pod of an evergreen shrub native to China and Vietnam. It is commonly used as a flavoring and a scent for products such as candles. Oils extracted from star anise were shown to improve laying as well as growth. The use of star anise oils in poultry also increases antioxidants in the liver and egg yolk and stimulates the immune system.[3] It also aids in production of digestive enzymes and increases liver function.
