Can Ducks Eat Avocados? Why is it so toxic?

We have already made it pretty clear in the intro that you can not feed avocado to ducks, be it backyard ducks or wild ducks. It won’t be occasional treats for ducks. Consider it as it is prohibited food for ducks, just like a citrus fruit. It won’t enrich your ducks’ balanced diet. Therefore, you can’t feed your ducks avocado.
However, a fruit so popular among humans demands some detail about why it is so toxic to most animals.
Avocado plants accumulate a fungicide called persin in their body, branches, leaves, skin, and seed. And this accumulation leaches into the flesh of the fruit as well. This persin is toxic to your duck.
So, what is persin?
Persin is a fatty acid derivative. These derivatives reside in the idioblast oil cells in avocado skin and leaves. Toxic persin is also an acetogenin which means that it has shown capabilities to kill cancer tumor cells.

But this same antimycotic compound is toxic for monogastric animals such as birds, reptiles, and even mammals like dogs and cats. And your duck also falls in this category. However, there is still a demand for more research on this topic.
Why persin is so toxic for ducks?

There is actually no research to answer that at a molecular level. However, there is research that uses persin to kill cancer cells from breast cancer patients in vitro. Persin increases the cytotoxic effect. This basically means it increases the cell-killing capabilities of immune cells and tamoxifen.
I hypothesize that persin activates some kind of immune response that destroys cells in certain parts of the body. That is why we are unable to see any kind of symptoms after ingestion of persin. Because native cells cause the problem in the bodies of ducks.
Can Baby Ducks Eat Avocado?
No, ducklings can’t eat avocados. There is no reason to think that ducklings would be any better than adult ducks at handling toxins. They are more susceptible to persin. And giving them the fruit will certainly cause death.

Can Avocados Kill Ducks?

Yes, avocado consumption can kill your feathered friends. Adult ducks might be able to survive but baby ducks don’t have a good chance.
Adult ducks might have 12 to 24 hours after avocado consumption. The death can also be sudden or as long as 48 hours.
Ducks Treatment of Toxicity from Avocado Consumption
There is no first aid here. The only thing you can do is run to the nearest veterinarian (pet doctor).
The veterinarians will start with a complete crop lavage or crop wash. This will empty the crop of any avocado sediments. After that, activated charcoal will be used to bind the toxins with it.
This will prevent the toxin from entering the cardiovascular system. In this process, your duck may be sedated, and a gavage tube might be used to get the coal in the right place as fast as possible.
This coal dosage will be given to them every 6 to 8 hours until the duck shows signs of recovery. In the meantime, the duck’s cardiovascular system, blood chemistry profile, and electrolyte levels should be monitored.

Avocado Substitutes

Avocados are high in fatty acids. All kinds of nuts can fill in for that, such as
- Walnuts
- Almonds etc.
And it’s not like you have to feed avocados to your pet duck. It is a snack, anyway, more like an occasional treat. You can offer them a variety of food such as fruits, veggies, and leafy greens. There are a variety of fruits that are packed with a wide variety of nutrients and can also fill in the nutrient demand of ducks while being a good snack as well. These are-
- Banana
- Kiwi
You can also give them vegetables to make up for the minerals that avocados contain-

- Kale
- Pea
- Collards
- Ripe tomatoes
- Cabbage, etc.
However, do not forget to provide fresh water for them. If they don’t consume enough water, different health issues, such as dehydration, might arise.
