ZyFend A Poultry Digestive Supplement
Backyard Chicken® ZyFend® A poultry digestive supplement is an all-natural water additive formulated to help maintain normal digestion and digestive health in poultry and waterfowl. It is intended for use during feed changes, stressful times, environmental changes, and other events that may challenge a flock’s normal routine.
The concentrated liquid is easy to add to fresh drinking water. Each 30 mL bottle supplies enough product for approximately 90 gallons when mixed at the labeled rate of six drops per gallon. The manufacturer states that no egg discard is required when ZyFend A is used as directed.
When to Use ZyFend A
ZyFend A can be incorporated into a flock-care routine during feed transitions, environmental changes, periods of stress, or other times when digestive support may be useful. The manufacturer also describes ongoing scheduled use throughout the year.
This supplement supports normal digestive function; it does not diagnose the reason for diarrhea, appetite changes, weight loss, poor condition, or abnormal droppings. Those signs can have many causes, including nutrition, environmental stress, infection, parasites, toxins, or other illness. Evaluate persistent or significant changes rather than assuming they are routine digestive upset. Our chicken poop guide explains normal and abnormal droppings and what changes may warrant attention.
Ingredients and Digestive-Support Formula
The current manufacturer ingredient list includes:
- Liquid yucca schidigera extract
- Dried Aspergillus oryzae fermentation extract
- Dried Aspergillus niger fermentation extract
- Essential oil of lemon
- Essential oil of grapefruit
- Essential oil of sweet fennel
- Essential oil of anise
The manufacturer describes the enzymes, essential oils, and yucca schidigera as supporting normal digestion and digestive health. Essential oils and yucca are listed for flavoring. Product formulas and labels can change, so review the ingredient statement on the bottle before use, especially if a veterinarian has advised avoiding a specific ingredient.
How to Mix and Give ZyFend A
- Shake the bottle well before each use.
- Beginning at three weeks of age, add six drops to every gallon of fresh drinking water.
- Provide the mixed water for seven consecutive days.
- Repeat the seven-day dosing schedule according to the current bottle directions. The manufacturer currently describes repeating it every three weeks or using it as otherwise directed.
- Clean poultry waterers regularly and prepare fresh water as needed.
Measure the water volume before adding the supplement so the concentration remains consistent. Do not assume that a stronger mixture will provide a better result. If the bottle you receive differs from online directions, follow the current package label or contact the manufacturer.
How Long Does a 30 mL Bottle Last?
At six drops per gallon, one 30 mL bottle treats approximately 90 gallons of drinking water. Actual calendar duration depends on flock size, weather, water consumption, spillage, and how often the supplement is used.
Prepare only the amount your birds can use appropriately, keep drinking equipment clean, and make sure birds have reliable access to water. ZyFend A is a supplement added to drinking water; it does not replace a nutritionally complete, age-appropriate poultry feed or routine access to clean water.
Is ZyFend A a Chicken Dewormer?
No. ZyFend A should be described as a poultry digestive supplement, not as an approved deworming drug, parasite treatment, or worm preventative. Some retailers and searchers use dewormer terminology, but the current manufacturer page positions the product as support for normal digestion and digestive health.
If you suspect intestinal worms, seek an accurate diagnosis. A veterinarian can recommend fecal testing and an appropriate treatment based on the parasite, bird, flock, and applicable egg or meat withdrawal guidance. Do not delay needed diagnosis or medication by relying on a digestive supplement to treat an infestation. Review our guide to chicken intestinal worms for signs, diagnostic guidance, treatment context, and prevention.
