“…However, BW values in other groups treated with methionine are slightly greater (>2,500 g) ( 52 ). Mutisya et al reported a mean BW among all groups from 1,990.0 g to 2,033.9 g, which corresponds to our data ( 53 ). Also, Shawle et al showed BW values of Cobb500 broilers on the 42nd day of the experiment that are less than our data (1,551–1,658 g) ( 54 ).…”

Probiotics are known for their beneficial effects on poultry health and wellbeing. One promising strategy for discovering Bacillus probiotics is selecting strains from the microbiota of healthy chickens and subsequent screening for potential biological activity. In this study, we focused on three probiotic strains isolated from the gastrointestinal tract of chickens bred in different housing types. In addition to the previously reported poultry probiotic Bacillus subtilis KATMIRA1933, three strains with antimutagenic and antioxidant properties Bacillus subtilis KB16, Bacillus subtilis KB41, and Bacillus amyloliquefaciens KB54, were investigated. Their potential effects on broiler health, growth performance, and the immune system were evaluated in vivo. Two hundred newly hatched Cobb500 broiler chickens were randomly divided into five groups (n = 40). Four groups received a standard diet supplemented with the studied bacilli for 42 days, and one group with no supplements was used as a control. Our data showed that all probiotics except Bacillus subtilis KATMIRA1933 colonized the intestines. Treatment with Bacillus subtilis KB54 showed a significant improvement in growth performance compared to other treated groups. When Bacillus subtilis KB41 and Bacillus amyloliquefaciens KB54 were applied, the most significant immune modulation was noticed through the promotion of IL-6 and IL-10. We concluded that Bacillus subtilis KB54 supplementation had the largest positive impact on broilers' health and growth performance.

“…Other studies on broilers, [9] there was no effect of BSF meal inclusion on carcass weight or carcass percentage in broiler chickens given BSF larvae meal during the growth and finishing stages. [4] for all treatments, the inclusion of BSF meals in the broiler diet had no significant influence on the dressed weight of carcasses (as well as the relative weight of internal organs (liver, heart, spleen, gizzard, and intestines).. In agreement with their result, the present study reported that broiler chicken in the BSF meal group did not affect the carcass cut yield and carcass percentage [3] .…”

Effect of dietary inclusion of black soldier fly larvae (Hermetia illucens) on broiler performance: A meta-analysis

et al. 2022

Black Soldier Fly (BSF, Hermetia illucens) is an insect species that potentially can be used as a protein source for broiler nutrition. This study aimed to evaluate different inclusion level of BSF on broiler performance and blood metabolites by integrating various data from related studies using meta-analysis. Total of 12 studies that comprised of 31 data points were integrated in the database. Parameters observed included Live Weight (LW), Average Daily Gain (ADG), Daily Feed Intake (DFI), Feed Conversion Ratio (FCR), blood metabolites, and carcass proportion. The database was statistically analyzed by using mixed model method. Different studies were considered as random effects, and the level of BSF was treated as fixed effects. The model statistics used were the p-values and the Akaike information criterion. The significance of an effect was stated when its p-value was < 0.05. The results revealed that BSF feeding had significant linearly reduction effect on LW, ADG, and FCR of broiler (P < 0.05) and significant linearly increase effect on DFI and carcass proportion. However, BSF did not significantly affect on blood metabolites of broilers. It can be concluded that BSF negatively affect the performance of broiler.

“…D. intortum has an acceptable protein content, which can be as high as 24% (Heinritz et al, 2012), and contains an appropriate content of Methionine-Lysine and Threonine, which are the most limiting amino acids in broiler chicken feed. D. intortum has been proven to positively impact egg quality, specifically improved yolk colour and chicken performance (Mutisya et al, 2021;Teguia and Beynen, 2005). Studies on the inclusion of legumes and forages in broiler bird diets have also been shown to reduce cholesterol concentration in the animals' blood and meat, as well as improve feed conversion efficiency through improved digestion and metabolism (Jiang et al, 2012;Krauze and Grela, 2010;Ponte et al, 2005;Purwin et al, 2014).…”

“…As a legume, D. intortum improves soil quality through nitrogen fixation, retain moisture and provides excellent fodder for livestock. We recently reported in previous studies that the combination of D. intortum and BSFL as feed ingredients in poultry diets improves animal performance and provide high returns to producers (Mutisya et al, 2021). The threelevel inclusion of D. intortum and BSFL consisted of a gradient of concentration of the two protein sources to evaluate their effect on sensory attributes and meat quality characteristics as these are critical drivers of consumer acceptance.…”

We evaluated the effect of dietary inclusion of different ratios of Desmodium intortum (DI) and black soldier fly larvae meal (BSFLM) on sensory traits and physicochemical qualities of broiler chicks meat. Three formulations: T1:75%BSFL:25%DI; T2:50%BSFL:50DI, and T3:25BSFL:75% DI as a protein source were tested. A conventional feed was used as the control diet. On day 42, the chickens were slaughtered, and thigh muscles were used for sensory and physicochemical evaluations. T1 was preferred for its flavour and tenderness, T2 for its juiciness and T3 for its colour, flavour, taste and overall acceptability scores. In terms of physical properties, all three types of meat had significantly lower moisture content and a higher water holding capacity than the control. T3 had the lowest moisture content, cooking loss and pH, whereas the meat from control diet had the highest cooking loss and pH. No significant differences were found in terms of meat lightness; however, meat from control diet showed the highest redness value, and T3 had the highest yellowness value. Dietary inclusion of DI-BSFL affected the fatty acid and cholesterol profiles of the meats. A holistic Principal Component Analysis indicated that the tested meats were distinct in their sensory and physicochemical properties. These variations in physicochemical properties may account for the difference in organoleptic perception, especially for T3. Further research should focus on feed modulation in relation to consumers’ preference and potential health benefits.
