“…(2015) who observed that 30% inclusion of TM meal in the diet of Shaver brown broilers decreased albumin‐to‐globulin ratio than in the SBM group (0.30 vs. 0.44). The authors attributed these results to the presence of chitin in the insect meal, which can act as a prebiotic and boost immune response (Selaledi et al., 2019). Additionally, van Huis (2013) reported a reduction in antibiotic usage in response to the application of insects in broiler's diet and this is so valuable because of the negative impact of antibiotics on human health (drug‐resistant bacteria strains).…”

“…The popularity of chicken meat is usually attributed to unparalleled nutritional value and its affordable pricing. Raising the price of grains due to the shortage of the ingredients in the future is one of the reasons for the rising cost of production that limit chicken meat consumption (Selaledi, Mbajiorgu, & Mabelebele, 2019). So, it is necessary to find sustainable feed ingredients to replace plant‐oriented feedstuffs, especially fish meal and soybean meal (Alston, Beddow, & Pardey, 2009; Dobermann, Swift, & Field, 2017; FAO, 2006).…”

“…Mealworms Tenebrio molitor L. (Coleoptera: Tenebrionidae) are the brown worm‐like larvae of darkling beetles. They include all the essential amino acids and are rich in protein, fat, fibre, potassium and phosphorus (Finke, 2015; Selaledi et al., 2019). Mealworms can convert vegetable waste with low quality into qualified protein, fat and energy in a short period (Makkar et al., 2014).…”

This study was conducted to evaluate the effects of dietary Tenebrio molitor larvae meal (TM meal) inclusion on the performance, carcass traits, caecum microbiota and blood parameters of broiler chickens. A total of 180‐day‐old chickens were allocated to three dietary groups with five replicate pens (12 birds/pen). Experimental diets were included a corn‐soybean basal diet, and two diets with 2.5% and 5% TM. TM‐included diets have been administered for periods of starter (1–10 days) and grower (11–25 days). A regular finisher diet was given to all groups during the 26–42 days of age. Diets containing TM meal did not influence feed intake and mortality percentage. Feed conversion ratio was lower with the 2.5% TM meal diet compared with the control group at starter period (p < .05). Besides, broiler chickens fed TM meal included diet had a higher body weight gain than the control group during 1–10 days of age (p < .05). The carcass characteristics and length and weight of different parts of small and large intestines were not influenced by diets. TM meal inclusion decreased the albumin‐to‐globulin ratio compared with the control group (p < .05). Additionally, lower total count of aerobic and Escherichia coli bacteria was observed in response to diet inclusion of 5% TM meal. Overall, the inclusion of TM meal in broilers' diet improved body weight gain and feed conversion ratio in the starting period, decreased albumin‐to‐globulin ratio and E. coli bacteria content.

“…It has been reported that yellow mealworms contain a high level of mono and polyunsaturated fatty acids as well as lipids and protein [ 20 , 21 , 22 ]. Apart from nutritional benefits, they also produce lower emission of greenhouse gases and ammonia as compared with traditional livestock [ 23 ].…”

To preserve the quality of the yellow mealworm, different drying methods are being explored by farmers and processors. However, the energy costs associated with these methods are usually high for smallholder insect-rearing farmers. Thus, the core aim of this study was to investigate different drying procedures and their impact on the chemical composition of yellow mealworm larvae. Yellow mealworms (exposed to sun, oven and freeze drying) were later analyzed for their chemical composition and body color. Crude protein (CP) content of freeze and oven-dried mealworms were similar (p > 0.05), but higher (p < 0.05) than those of the sun-dried samples. The b (yellowness) color of the sun-dried samples scored the lowest value (p < 0.05) in comparison with both oven and freeze-dried samples. The majority of the essential amino acids were higher (p < 0.05) in the sun-dried mealworms than both oven and freeze-dried samples. Similarly, the fat content of sun-dried mealworms was higher (p < 0.05) than if they had been oven or freeze dried. However, SFA (saturated fatty acids), PUFA (polyunsaturated fatty acids) and n-6 fatty acids were similar (p > 0.05) for all drying methods. We, therefore, conclude that sun drying resulted in the same nutritional composition as freeze and oven drying despite the noted color changes. Freeze and oven-drying strategies can be used to formulate mealworm-based feed and food products without noticeable nutritional changes. For the benefit of small-scale insect-rearing farmers, an appropriate drying technology that is affordable and easy to use should be developed considering the needs and experiences of these farmers.

“…But the deterioration of fisheries has reduced the availability of FM and increased its price (Sanchez-Muros et al, 2014). The inclusion of SBM and FM in broiler diets has become dependent on imports to an ever-greater degree, resulting in even higher costs and less profitable broiler production (Selaledi et al, 2019). Therefore, many researchers investigated alternative cheaper new protein source feedstuffs for SBM and FM that do not have adverse effects on broiler performance (Onsongo et al, 2018;Zadeh et al, 2019).…”

The effects of replacing fish meal (FM) in the diet with defatted mealworm larvae meal (DMLM) on growth, carcass, and biochemical constituents of serum of Japanese quail chicks were investigated. A total of 600 unsexed one-day-old chicks were allotted to five dietary treatments with six replicates of 20 chicks each. The diets were formulated by replacing FM with DMLM at the levels of 25% (D25), 50% (D50), 75% (D75), and 100% (D100). The FM, D25 and D50 diets resulted in greater final bodyweight, higher bodyweight gain, and improved feed conversion ratio compared with the other diets. Diets that contained DMLM decreased the feed intake compared with the FM diet. The FM and D25 diets increased the hot and cold carcass yields compared with the other diets, whereas the D75 and D100 diets significantly enhanced the relative weight of the small intestine and abdominal fat compared with FM, D25, and D50. The replacement of FM with DMLM reduced the serum globulin, total cholesterol and triglyceride levels, and the albumin to globulin ratio significantly. The best protein and energy efficiency ratios and European efficiency factor were obtained with the D25 and D50 diets. In conclusion, the replacement of FM with DMLM at the levels of 25% and 50% produced positive results in growth performance, in serum albumin to globulin ratio, and in nutrient use efficiency in quail.Keywords: performance, serum biochemistry, slaughtering
