Mealworms and black soldier fly (BSF) larvae are two of the most reared insects at an industrial scale. Both may feed on by-products from agricultural food industries. Feed efficiency is one important aspects such processes varies between species substrates depends metabolic performance larvae. Compared to each other, both hold advantageous capabilities affecting their efficiency, likely depending substrate. We mealworms BSF a diverse selection industries, quantified major rates across life spans, compared performances. The type had stronger effects growth than Generally, were in terms highest maximal specific rate (0.50–0.77 day−1) assimilation (0.81–1.16 shortest development period (23–25 days) but disadvantageous maintenance cost (0.07–0.21 day−1). In mealworms, 0.02–0.11 day−1, 0.16–0.37 was least 65–93 days, while only 0.02–0.05 day−1. contrast larvae, weight dependent lowest largest individuals. combined outcome these resulted average carbon net NGE*avg 0.16–0.40 0.33–0.56 span. It thus seems that more versatile somewhat efficient converting into mealworms. Differences affected substrate conversion efficiencies (i.e., ratio gain reduced substrates) impact overall insect farming.

Feeding low crude protein (LCP) diets supplemented with crystalline amino acids improves environmental and welfare parameters of broilers. However, increased body fat contents in broilers fed LCP have become a concern. Black soldier fly larvae oil (BSFLO), rich lauric acid, has been reported to inhibit lipogenesis reduce fat. A 3 × 2 factorial experiment was conducted evaluate the effect BSFLO on performance, blood biochemistry, carcass quality, metabolism gene expression, litter quality protein-reduced diets. total 288 were divided into 6 treatments: three CP levels (200, 185, or 170 g/kg; high [HCP], medium [MCP], [LCP]) two sources (BSFLO Crude Palm Oil [CPO]), replicate pens 8 birds each.

The growing global demand for food, particularly animal protein, is intensifying challenges related to food security and environmental sustainability. increase in organic waste generation, coupled with inefficient management, further deteriorating living conditions by negatively impacting the environment public health, especially developing nations. This study investigated potential of black soldier fly larvae (BSFL) recycle major daily fractions Nepal. BSFL were exposed seven different biowaste-based substrates locally sourced from fruit vegetable markets, farms, industries. Additionally, evaluated rapeseed cake as a supplement enhance growth nutritional content. survival rates exceeded 80 % on industry but dropped 63 high-moisture like waste. Mixed (14.7 mg/day) bakery (11.5 supported higher average weight gain, likely due their better nutrient values (soluble carbohydrates proteins). Although alone hindered larval growth, its supplementation biowastes improved survival, bioconversion rates, increased protein content up 32 %, reduced fat 36 %. These findings indicate can effectively diverse, available wastes countries Nepal, providing sustainable source domestic contributing feed security.
