The importance of fibre in the digestive process cannot be overemphasized.

Leeks have been found to contain a high fiber content that is both soluble and insoluble.

Soluble fiber helps promote healthy digestion and prevents constipation in your pets. 

Insoluble fiber on the other hand remains in the digestive system, aiding in the cleaning of the digestive tract and promoting bowel movements.

  1. Calcium 

Calcium is the primary mineral for bone, teeth and egg improvement. The bone density of ducks is increased due to the high level of Calcium present in leeks. 

This will aid in the prevention of fractures and distortions of the bones. Calcium also aids quality egg development and formation in the female ducks. 

Calcium deficiencies can lead to rickets and osteoporosis in your ducks, however feeding them leeks can easily fix this

  1. Antioxidants

Leeks are a rich source of antioxidants such as polyphenols.

Antioxidants are agents that reduce and eliminate oxidants in the body systems of your ducks.

They generally work to help the ducks fight illness and reduce stress. If your ducks are stressed, it would reduce their welfare and production capacities. 

Feeding your ducks leeks would help keep them safe from sickness.

How Often Should I Feed Them Leeks?

Leeks like every other vegetable should only be fed to ducks in moderation.

Some duck owners make the mistake of replacing their ducks diets with leeks or vegetables just because their ducks happen to like them.

This is wrong however as leeks do not contain all the nutrients your ducks require to grow and mature.

The main diet of your ducks should always remain poultry commercial feed which provides them with the necessary nutrients they need to grow.

Leeks should naturally serve as supplements and as such should only make up 10% of their total diet.

You can feed them leeks at the most two times a week to avoid the ducks getting overdependent on leeks.

Also, mix it with other vegetables from time to time to give them a different taste.

Here is a comprehensive list of everything ducks can eat
