What to Feed Crickets

Feeding crickets the right diet is crucial for their growth, reproduction, and overall health. Various studies have explored different feed types and their impacts on cricket performance, providing valuable insights for cricket breeders and researchers. This article reviews the findings from several research papers on the optimal diets for crickets, focusing on protein levels, agricultural by-products, and specific plant-based feeds.

Protein Levels in Cricket Diets

Protein is a vital component of cricket diets, significantly influencing their growth and feed efficiency. A study on the two-spotted cricket (Gryllus bimaculatus) found that a diet containing 22% crude protein (CP) resulted in greater body weight and the lowest feed conversion ratio (FCR) compared to diets with lower protein levels. Additionally, a two-phase feeding strategy, starting with 22% CP and transitioning to 20% CP, was identified as a cost-effective approach for sustainable cricket production1.

Agricultural and Food Industry By-Products

Using agricultural and food industry by-products as cricket feed can be both economical and sustainable. Research on Cambodian field crickets (Teleogryllus testaceus) demonstrated that crickets fed cassava plant tops and Cleome rutidosperma had similar growth and survival rates to those fed commercial chicken feed. Other by-products like rice bran, spent grain, and residue from mungbean sprout production also showed potential, although some weeds like Alternanthera sessilis and Amaranthus spinosus were less effective2.

Specific Plant-Based Feeds

Different plant-based feeds can impact cricket reproduction and growth. A study on Gryllus miratus indicated that chicory leaves were the most effective feed for maximizing the number and weight of eggs produced by crickets. Other leafy greens like kale, green cabbage, and spinach also supported egg production but to a lesser extent3.

Agro-Byproducts for Growth Performance

The growth performance of common house crickets (Acheta domesticus) and field crickets (Gryllus bimaculatus) was evaluated using various agro-byproducts. The study found that rice bran combined with blood meal, spent grain, or spent yeast could support cricket growth, with grower’s mash serving as a control. The results indicated that both species and the type of feed significantly affected the crickets’ growth rates4.

Cricket Meal as a Protein Supplement

Cricket meal, derived from Gryllus bimaculatus, has been investigated as a protein supplement in various animal diets. It contains high levels of crude protein and essential amino acids, making it a promising alternative to traditional protein sources like soybean meal. Studies have shown that cricket meal can improve feed efficiency, ruminal fermentation, and microbial protein synthesis in livestock, while also reducing methane production5 9.

Conclusion

The optimal diet for crickets depends on the specific goals of the breeder, whether it is maximizing growth, reproduction, or sustainability. High-protein diets, particularly those containing around 22% crude protein, are beneficial for growth and feed efficiency. Agricultural by-products and specific plant-based feeds can also be effective, offering cost-effective and sustainable alternatives. Further research and practical trials will continue to refine these feeding strategies, contributing to more efficient and sustainable cricket farming practices.
