“…Furthermore, the hemato-biochemical values reported in this study fell within the normal ranges reported for quails [3,26,27]. In addition, several studies also revealed no significant dietary effects on blood parameters of broilers [21], laying hens [22], and Barbary partridges [28] when fed with a variety of insect meals.…”

A Nutritional Evaluation of Insect Meal as a Sustainable Protein Source for Jumbo Quails: Physiological and Meat Quality Responses

2019

The use of insect meals in place of soybean meal in diets is critical for sustainable intensification of poultry production, but the utility of this alternative dietary protein source is unknown for the Jumbo quail. Therefore, this study investigated the effect of partial substitution of soybean with black soldier fly larvae (BSFL) meal on feed intake, physiological, and meat quality parameters of Jumbo quails. Three hundred and fifteen mixed-gender quails (53.8 ± 5.19 g live-weight) were reared on five isonitrogenous and isoenergetic experimental diets formulated by replacing soybean products with BSFL meal at 0 (BSFL0), 25 (BSFL25), 50 (BSFL50), 75 (BSFL75), and 100 (BSFL100) g/kg. Feed intake, body weight gain, gain-to-feed ratio (G:F), blood parameters, and carcass and meat quality traits were determined. Quadratic trends were observed for overall feed intake (y = 605 (±17.56) + 2.1 (±0.82)x − 0.02 (±0.008)x2; R2 = 0.20; p = 0.023) and overall body weight gain (y = 155 (±4.70) + 0.57 (±0.22)x − 0.005 (±0.002)x2; R2 = 0.22; p = 0.026) in response to BSFL levels. However, there were neither linear nor quadratic trends for meat quality and blood parameters, except for albumin-to-globulin ratio. Only gizzard size linearly increased (y = 0.05 (±0.004)x + 2.3 (±0.09); R2 = 0.18; p = 0.04) with BSFL levels. We concluded that BSFL meal could replace soybean products in Jumbo quail diets at 54 g/kg without compromising weight gain and meat quality.

“…In laying hens, better feed conversion was seen in hens with insect meal in their diet; however, there was more variation in egg sizes (Marono ). Similar results of increased feed conversion and growth rates on insect meal diets compared to a standard soya bean control were seen with Barbary partridges (Loponte ).…”

Opportunities and hurdles of edible insects for food and feed

2017

Entomophagy, the consumption of insects, is promoted as an alternative sustainable source of protein for humans and animals. Seminal literature highlights predominantly the benefits, but with limited empirical support and evaluation. We highlight the historical significance of entomophagy by humans and key opportunities and hurdles identified by research to date, paying particular attention to research gaps. It is known that insects present a nutritional opportunity, being generally high in protein and key micronutrients, but it is unclear how their nutritional quality is influenced by what they are fed. Research indicates that, in ideal conditions, insects have a smaller environmental impact than more traditional Western forms of animal protein; less known is how to scale up insect production while maintaining these environmental benefits. Studies overall show that insects could make valuable economic and nutritional contributions to the food or feed systems, but there are no clear regulations in place to bring insects into such supply systems. Future research needs to examine how the nutritional value of insects can be managed systematically, establish clear processing and storage methodology, define rearing practices and implement regulations with regard to food and feed safety. Each of these aspects should be considered within the specifics of concrete supply and value chains, depending on whether insects are intended for food or for feed, to ensure insects are a sound economic, nutritional and sustainable protein alternative -not just a more expensive version of poultry for food, or soya for feed.

“…The RBC counts and Hb concentration in blood increased to a level of 37% and 35.3%, respectively, at a FM replacement level of 50% with BSFLM. These results are consistent with the reports by Marono et al (2017) and Loponte et al (2017), who reported that dietary BSFLM inclusion positively affected the blood profile of laying hens and Barbary partridges, in terms of higher globulin levels. Our results may be attributed to high digestibility of insect-based protein and high levels of minerals such as iron, which is required for the formation of haemoglobin in the pigs.…”
