Benefits of feeding earthworms to Bearded dragons
Protein is very important to the health of young bearded dragons. You see, both baby and juvenile bearded dragons need a lot of protein in their diet to aid in growth and development.
That one of the reasons their main diet is made of insects and the other diet is made of veggies and fruits and nectaries.
Earthworms have a protein content of about 60-70%. This makes earthworms a good source of protein for your bearded dragon especially young dragons.
Even better is the fact that you can gut load your earthworms if you decide to rear them yourself and improve their nutritional load further.
You know that keeping your bearded dragon hydrated is very important right? in fact, we wrote a very detailed article on how to make sure your bearded dragon is hydrated. You can check it right here.
Unfortunately, some bearded dragons may be adamant to drink from the bowl. That means the best way to keep them hydrated is through spritzing or by feeding them food with high water content.
Earthworm has a very high water content making them a good choice to keep your bearded dragon fed and hydrated.
However, you should only offer earthworms as a treat and not as a staple food. Feeding earthworms daily can easily lead to diarrhea due to the high water content given that you dragon is also eating other foods.
As a rule of thumb, your bearded dragon should only drink about 10ml of water per 300g of weight.
The 10ml capacity includes water from foods and one that they drink directly.
Other benefits that your bearded dragon gets from eating earthworms is minerals such as selenium and vitamins.
By gut loading your earthworms, your can help increase the level of vitamins and minerals in the earthworms and transfer the same to your pet.
Risks of feeding Earthworms to Bearded Dragons
Calcium phosphorus ratio
Calcium is very important mineral towards the health development of bearded dragon bones.
Low calcium levels can easily lead to a very dangerous disease known as metabolic bone disease.
To make sure your young bearded dragons develop properly especially for breeders, you should make sure your dragons are getting enough calcium supplements.
In as much as you are feeding your bearded dragon calcium supplements, you need to be wary of two other minerals namely oxalates and phosphorus.
Feeding your bearded dragon feeds high in oxalates such as avocado and spinach prevents calcium from being absorbed into the body, as calcium reacts with oxalates to form calcium oxalates.
Therefore always keep off or reduce the amount of food that contains oxalates in the diet of your bearded dragon.
As mentioned earlier phosphorus is the next culprit, it will react with calcium to form calcium phosphates that prevent calcium from absorbed in the body of your pet.
Fortunately, since most of the foods that most lizards consume including bearded dragons have some phosphorus in them, there is a recommended ratio of calcium to phosphorus that is either 1:1 or 2:1.
The ratio of calcium to phosphorus is a bit awful. The table below shows the calculation of the Ca:P ratio.
As you can see the ratio is way above the recommended value, as a result, it is advisable to not feed earthworms on daily basis but only as a treat like once a week.
Earthworms are also loaded with fat. Feeding your bearded dragon too much fat can be dangerous to its health and development.
You see, compared to their wild relatives’ domesticated dragons do not exercise as much as they should.
Meaning when you overfeed them fat, they will not be able to burn it down like they woud in the wild.
That why it is very important for you to make sure you exercise your bearded dragon now and then, swimming can be a great way to keep your pet exercised.
Feeding earthworms on daily basis will make your bearded dragon obese, therefore while young bearded dragon can afford to eat earthworms twice a week.
Adult, bearded dragon should be fed earthworms about once or twice a month.
