Gryllus testaceus walker (crickets) farming management, chemical composition, nutritive profile, and their effect on animal digestibility

Abstract

Commonly, the life span of the cricket is very short, reaching from 60 to 70 days and the average egg production lies within the range of 200-1,500 eggs/female. The female can mate with many males and can produce more fertile eggs. The body composition of an adult cricket on analysis showed that it contains dry matter 33.30%, crude protein 63.30%, crude fat 5.20%, ash 5.60%, calcium 10.10%, phosphorous 7.90%, zinc 215.0 mg/kg, and copper 15.00 mg/kg on dry matter basis, respectively. The dry matter digestibility diet was highest for whole cricket (WC, with legs) and the digestibility of ash, crude fiber, and crude fat was higher than form body cricket (BC, removal of legs). The WC and BC diets had lower feed conversion rates than control diets, and higher nitrogen retention (digestion). It was concluded that crickets are potential feed ingredients for ruminants and non-ruminants, especially as protein supplements methane emissions are low in vitro and high ash digestibility indicates the ability to reduce mineral deficiencies.

WITHDRAWN: Potential use of insect bioactive compounds in animal rations

“…The insect's diets bene t in animal feeds, the inclusion of insects in the animal diet that not will only develop the circulation of the agricultural food sector, but also balance diet for farmed animals and will also foodstuffs that meet their dietary requirements. Insects species are mostly used in animal diets containing 55% and 76% of crude protein and nutritional value of amino acids (AA) 90,91 . The high amount protein in edible insect powder and those enhancing the protein quality in animal feeds.…”

Nutritional and Functional Properties of Defatted Flour, Protein Concentrates, and Isolates of Brachytrupes membranaceus (Orthoptera: Gryllidae) (Drury: 1773) and Macrotermes subhyalinus (Isoptera: Blattodea) (Rambur: 1842) from Burkina Faso

“…The protein and fat contents of Brachytrupes membranaceus were lower than those previously reported by Agbidye et al [33]. The ash, protein, and lipid contents of Macrotermes subhyalinus were higher and lower than those reported for Macrotermes nigeriensis [34] and cricket [35], respectively.…”

“…The zinc and calcium contents of Brachytrupes membranaceus were higher than those of Brachytrupes orientalis, while the iron, magnesium, potassium, and sodium contents were lower than those of the same species [36]. Shah and Wanapat [35] reported high levels of iron and zinc in crickets (11.6 and 21.5 mg/100 g, respectively). Akullo et al [37] reported higher iron, potassium, sodium, and zinc levels in Macrotermes bellicosus.…”

Comparative Effect of Cricket Protein Powder and Soy Protein Isolate on Gel Properties of Indian Mackerel Surimi

“…In addition, CP has been the source of nutritional values that contain not only high amounts of protein but also minerals and bioactive compounds that may have the capacity to enhance the gel properties. Kosečková et al [ 60 ] reported that CP ( A. domesticus ) contained several minerals, among which calcium was the dominant, estimated at 176–256 mg/100 g dry weight, and chitin and chitosan were also found in CP [ 61 ]. Calcium and chitosan may participate in the gel formation due to activation of the transglutaminase (TGase) enzyme.…”
