“…The colour of the breast muscle samples was measured at 24 h p.m. using a chromameter (Minolta CR 200, Ahrensburg, Germany) with triplicate measurements from a freshly cut surface using the parameters L* (brightness), a* (red-green) and b* (yellow-blue). Chroma ((a *2 +b *2 ) 1/2 ) and hue (arctan (b * /a * )) indexes were calculated (Kongsup et al, 2022). Water holding capacity was measured following descriptions of Grosse et al (1975).…”

A feeding experiment was conducted to investigate the impact of feeding defrosted whole black soldier fly larvae (BSFL) to broilers in increasing levels in the ration on blood metabolites, carcass characteristics (CC) and on changes in fatty acid (FA) composition in plasma, muscle and abdominal fat. Day-old chicks (Ross-308; n=252) were assigned to one of four groups each with 6 replicate pens (10-11 birds/pen). The birds were fed either a demand-oriented age-specific control (CON) diet and had no access to BSFL, or fed CON plus BSFL at 10% (L10), 20% (L20) or 30% (L30) of CON feed intake. At weeks (wk) 4 and 6, birds (2 per pen) were slaughtered to collect blood, breast muscle, and abdominal fat samples and to determine CC. Plasma triglyceride concentrations increased in a dose dependent manner with increasing levels of whole BSFL compared with CON (P<0.05). The L30 and L20 had higher plasma non-esterified FA concentrations than CON (P<0.05). There were no differences in slaughter weight and CC between groups (P>0.05). Broilers fed 30% BSFL had the highest saturated FA proportion in plasma, muscle and abdominal fat and the lowest monounsaturated FA proportion in abdominal fat tissue (P<0.05). The levels of total polyunsaturated FA in plasma and abdominal fat were lower in L30 than in CON (P<0.05). In plasma, muscle and abdominal fat, the proportion of conjugated linoleic acid (isomer C18:2cis-9, trans-11) was highest in L30 followed by L20 and L10 compared with CON (P<0.05). Overall, whole BSFL could be included in broiler diets up to 20% to promote sustainability in broiler farming without adverse effects on slaughter weight, meat quality and FA compositions, whereas, the highest inclusion level (i.e. 30%) of whole BSFL in the daily ration was associated with altered FA composition in plasma, fat and meat.

“…The effect of silkworm meal on the productive performance of poultry was assessed in different studies [14,17,29,30]. However, findings are somewhat contrasting and this is attributable to the fact that silkworm species (Bombyx mori vs. Samia ricini), inclusion level and product type (i.e., full-fat, defatted), poultry species, and productive type (broiler chicken, broiler quail, layer chicken, etc.)…”

The present study was conducted to assess the effects of a 4% defatted silkworm (SWM-DEF) meal dietary incorporation into chickens’ diet at different growth stages on growth performances, carcass, and meat quality traits. A total of 90 Ross 308 one-day-old male broiler chickens were randomly allocated into 3 dietary groups of 5 replicated pens/diet (6 chickens/pen). One group was fed a standard soybean-based diet (C); group SWM1 consumed a starter diet (1–10 days of age) including 4% SWM-DEF and then the C diet up to slaughter (11–42 days of age); group SWM2 was fed with the C diet in the starter phase and the 4% SWM-DEF diet up to slaughter. Individual live weight and pen feed intake were determined at the end of each feeding phase: starter, grower, and finisher. Weight gain and FCR were then calculated. At 42 days of age, chickens were slaughtered and carcass traits determined. Leg and breast physico-chemical meat quality was also evaluated. Results confirmed that SWM-DEF could be a possible alternative feed source for chickens since growth performance, carcass, and meat physical traits were overall comparable in the three treatment groups. The feeding stage seemed to play a relevant impact on the sole meat protein content (SWM1 < SMW2 and C; p < 0.001). Concluding, the results available to date indicate that 4% SWM-DEF can be provided to chickens in different growth phases, and the choice of the inclusion period is more an industrial cost-benefit evaluation. From the scientific point of view, however, an administration in the grower-finisher phase rather than in the starter one provided the best meat nutritional quality. Further investigations should focus on the impact on meat fatty acids profile and sensory traits, which are of utmost importance for consumers.

“…It was suggested by Kongsup et al (2022) that addition of eri silkworm (S. ricini) pupae at 10% in the diet formulation of broilers gave a higher cold carcass weight and skin yellowness and this formulation did not cause any harmful consequences on growth performance, health status and meat quality and can be used as alternative protein sources for broilers, however, on the other hand, addition of eri silkworm pupae at 15% led to poor outcomes and hence not recommended.…”

The animal requires certain essential nutrients in their diet in order to achieve the desired growth and development which leads to income generation. The dietary feed which are available in the market for fishes and monogastric animals such as poultry, pig etc. are quite expensive and are not easily available. Silkworm pupae meal, which is a waste of the sericultural industry, is a highly nutritious and cost-effective product that can fulfil the dietary requirement and successfully utilized as a feed for these organisms. The present review displays the utilization of silkworm (both mulberry as well as non-mulberry) pupae as an alternate source of protein in fish, poultry, and pig feeding.
