Are you having a hard time choosing which insect feeder is best for gecko’s nourishment? Worry no more as we got you covered!

Commonly, reptiles feed on commercially available insect feeders in local pet stores. The problem however is the quality of nutrients it contains. Most insects bought in the market are insufficient when it comes to vitamins and minerals and are not sufficient to promote a healthy and balanced diet.

Gut loading is the way of ensuring that your reptiles are getting the right nutrients for their body. Through this process, the insect feeders or prey animals are fed highly nutritious food so that they can pass the same nutrients to the reptiles ones they are fed. In this way, insects such as crickets, mealworms, and dubia roaches are prepared to be the best food containing lots of nutritional value, suitable for your reptiles’ development.

Gut loading can be made by feeding your insect feeders or prey animals with vegetables, fruits, and other nutritious products designed for such purposes. You can also feed them with the right portion of protein, fats, carbohydrates, vitamins, and minerals. And the moment these insects are eaten by your pets, the nutrients absorbed by the insects will be transferred to your pet.

What Are The Benefits of Gut Loading?

According to research, most insects lack calcium and Vitamin A nutrients in their body. However, when a higher concentration of such vitamins and minerals is added to their diet, it also increases the levels of dietary elements. 

The process of gut loading will allow the optimal concentration of nutrients in the insect’s body. This is especially true when insect feeders are given nutrient-dense foods. Aside from these benefits, it will also prevent diseases resulting from nutrient and mineral deficiency such as Metabolic Bone Diseases or MBD and hypovitaminosis.

Gut loading helps in curing Metabolic Bone Disease or MBD. 

This is an issue for most reptiles which has an insufficient supply of calcium and vitamin D in their body. Common symptoms are swollen legs and arched spine and softening of jaws. This kind of disease can be improved by dietary supplementation.

To cure this disease, all you have to do is add calcium supplements to your gut-loaded insects. This will help strengthen their bones and keep them healthy and active.

Gut loading can also help cure Hypovitaminosis.

Hypovitaminosis will happen if the insects fed by your reptiles do not contain essential nutrients for their growth and development. It occurs when there is a deficiency in vitamins A, B, E, and other essential vitamins that the body needs. 

The common symptoms of hypovitaminosis are lethargy, decrease in appetite, weight loss and skin problems. Gut loading the insect with nutritious food will provide them with the vitamins needed therefore curing such deficiency.

On the other hand, reptiles in captivity depend on the insect feeders given for their daily consumption. They depend on such insects for nutrition, growth, and development. 

Insect feeders which are available on the market are lacking when it comes to nutritional value. Therefore, it must be gut-loaded with materials containing high-quality vitamins and minerals so that it will continue to provide your geckos the essential nurtient they need in order to grow healthy and happy.
