“…The shear force values observed in this study are close to Schilling et al (2010) who reported shear force values of (15.1-16.3N), all shear force values in these studies were less than 30 N an indication of tender meat that would be exceedingly acceptable to consumers. In addition, the current study is in agreement with (Gunya et al 2019) whose findings reported that the inclusion of Eisenia foetida meal in broiler chickens positively influenced breast meat tenderness.…”

“…Of which, H. illucens and T. molitor contains 60% and 69% of crude protein (Barragan-Fonseca et al 2017;Veldkamp et al 2012) respectively. More so, our findings are comparable with Gunya et al (2019) who reported breast meat pH 6.2 of broilers fed Eisenia foetida. Interestingly, E. foetida contains 56% crude protein (Fadaee 2012) comparable with I. belina 53.7% (Lautenschl€ ager et al 2017).…”

The study aimed to evaluate the effect of dietary graded levels of Imbrasia belina at 0%, 4%, 8% and 12% of broiler diets on meat quality and sensory attributes. A total of 360 one-day-old broiler chicks, were fed graded I. belina diets and slaughtered on day 35. Body weight (BW), Average Daily Gain (ADG), Feed Intake (FI) and Feed Conversion Ratio (FCR) were recorded. Breast muscles were evaluated for ultimate pH, meat colour (L Ã (lightness), a Ã (redness), b Ã (yellowness), tenderness, cooking loss. Forty consumer panellists evaluated sensory attributes. On day 28, the ADG in birds fed IB4 (88.06 g) and control (80.09 g) were statistically similar. On day 28 and 35 FI of broiler chickens fed control (147.47 g; 178.45 g) was the highest. The highest values for L Ã were observed in IB1, but not significantly different (p > .05) from IB3 and IB4. For redness, a Ã values were highest in IB3 and lowest in IB1. Lightness, yellowness, pH24 and Hue showed a quadratic response to increasing levels of IB meal. The shear force values were highest in IB1 (11.27), but not significantly different (p > .05) from IB3 (9.97) and IB4 (9.85). However, the tenderness scores were observed to be highest from IB3 (7.00). The highest acceptability scores of the breast meat were from IB2 (7.65). In conclusion, adding graded levels of I. belina meal up to 12% into diets of broilers had a positive effect on growth performance, meat quality and sensory attributes. HIGHLIGHTS Dietary inclusion levels of I. belina meal increased body weight gains in dietary treatment groups. The shear force in all dietary treatment groups decreased compared to the control. The tenderness of breast meat was found to be significantly influenced by the dietary treatment ARTICLE HISTORY

“…Likewise, Bahadori et al (2017) found no statistical differences for carcass characteristics of broilers fed different levels of EW and VH in the diet. However, our results partially disagree with Gunya et al (2019) who provided up to 10% EW in the broiler diet and observed a decrease in wing yield with the use of 10% EW and an increase in the yield of drumsticks with the use of 3% EW. However, the use of 10% EW in the diet increased the relative weight of gizzard.…”

“…However, the use of 10% EW in the diet increased the relative weight of gizzard. Gunya et al (2019) speculated that the increase in the percentage of gizzard weight is due to hyperplasia of the gizzard as a result of increased mechanical activity dealing with the high dietary protein levels.…”

“…Bahadori et al (2017) observed a reduction in water retention in the thigh musculature, which was not seen in breast musculature and may be due to different characteristics of the musculature in the two sites. Gunya et al (2019) observed an increase in water loss from the breast in broilers receiving 10% EW in the diet, which may be a result of the muscle's ability to retain water (Abu et al 2015).…”

The objective of this study was to evaluate the use of earthworm meal (EW) and vermi-humus (VH) in broiler diets. A total of 225 day-old male broilers were divided into 5 treatment groups with 3 repetitions of 3 birds each. The treatment groups were: T1control (no EW or VH; T2 À 1.0% EW and 0% VH; T3 À 1.0% EW and 1.0% VH; T4 À 1.0% EW and 1.5% VH; and T5: 1.0% EW and 2.0% VH. The birds received (EW) and (VH) for 14 d, and after this period, they received the common diet. The birds were reared for 42 d and, at 42 d, one representative broiler chicken per pen, close to the average body weight, was selected for blood sampling using a sterile needle and heparinised vacuum tube. Performance data, blood results, immunity, ileum morphology and microbiota, the relative weight of carcass components and gastrointestinal organs, malondialdehyde (MDA) content, and breast and thigh meat quality were evaluated. EW and VH had a positive effect on the immune response of broilers, as well as producing a reduction in the aerobic bacteria in the birds' intestines. HIGHLIGHTSProtein is a limiting factor for broiler performance, carcass yield, and meat quality; Poultry industry is searching for new protein sources which can be used on broiler diets; Insects meal are good protein sources in broiler nutrition and can be used on diets without compromising its performance.
