The demand for sustainable and ethically farmed animal products is on the rise as consumers become more environmentally welfare conscious. need to diminish consumption of soybean meal urgent, companies are looking ways respond this necessity by alternatives meal. This study assessed impact introducing whole dehydrated live black soldier fly larvae (BSFL) into diet an indigenous chicken breed environmental enrichment. A total 144 39-day-old male Bianca di Saluzzo chickens were distributed among 18 pens assigned three different experimental groups. control group received a where was entirely replaced alternative ingredients. two groups given same supplemented with 5% expected daily feed intake BSFL or BSFL. Throughout trial period (from bird age 39–174 days age), weight recorded every 21 days, average gain, intake, conversion ratio calculated. time required birds consume times week.

A wide range of insects are being considered as potential candidate sources dietary protein; however, it was only recently that the European Union, with Regulation (EU) 2017/893 May 24, first allowed use black soldier fly (Hermetia illucens), common housefly (Musca domestica), yellow mealworm (Tenebrio molitor), lesser (Alphitobius diaperinus), house cricket (Acheta domesticus), banded (Gryllodes sigillatus) and field (Gryllus assimilis) feed in aquaculture. With 2021/1372 August 17, their extended to poultry pig feed. Most studies on feeding have focused benefits insect meals. However, live part natural diet poultry, so more effort should be directed at evaluating further, not relation effect performance product quality, but also from perspective bird welfare. No adverse effects been observed inclusion larvae up 10% daily intake. further research is needed establish levels most advantageous for bird's health, economically sustainable breeder without unnecessary waste resources. Live provide fresh, unaltered nutrients they stimulate birds express innate behaviours which may improve birds' The production distribution laborious expensive, especially large-scale systems. Dehydrated easier handle, no complex protocols need implemented prior offering bird. By contrast, dehydrated potentially less attractive birds.

The literature on poultry welfare and behavior reports numerous promising effects derived from the administration of live or dehydrated black soldier fly larvae (BSFL) as environmental enrichment; however, their use in slow-growing male chickens has never been evaluated. To fill this gap, we divided a total 144 Bianca di Saluzzo chicks aged 39 days old into three experimental groups (six replicates, eight birds/replicate): control (C, no enrichment provided), (DL, 4.12% fed), (LL, 15.38% reared until 147 age. Explorative aggressive patterns were analyzed, concomitance with tonic immobility test avoidance distance test, heterophile to lymphocyte -H/L- ratio), excreta corticosterone metabolites (ECM) matrices. Overall, LL DL supplementation both effective at mitigating interactions among (P < 0.05), while frequency indoor explorative was lower group compared C 0.01). By contrast, found differences fear reduction during 0.05). We trend for H/L ratio be LL<DL = 0.051), ECM concentrations significantly 0.001). In conclusion, have potential produce beneficial outcomes chickens.

The aim of the present study was to assess effects dietary supplementation with live black soldier fly (BSF) and yellow mealworm (YMW) larvae on Muscovy duck slaughter performance, meat quality (pH, color, water holding capacity, shear force), proximate composition, fatty acid profile. A total 126 female ducks were split into three groups: control (commercial feed only), BSF + larvae), YMW larvae). At 55 days age, weight assessed. results showed absence any differences in performance or traits between groups exception thigh composition. Indeed, moisture content lower two insect-fed compared group, while crude protein higher than birds (P < 0.05). We also observed a proportion C12:0 from birds, C14:0 C16:1 n7 group This confirms that providing insect does not compromise overall these birds.

Abstract The overall beneficial effect of live black soldier fly larvae (BSFL) on the welfare broiler chickens, turkeys, and laying hens has already been discussed in literature. However, scant information is available regarding benefits feeding BSFL to medium‐growing chicken hybrids reared under organic/free‐range conditions, whose frequently cited as being inadequate. aim this research was advance our knowledge topic. To end, 240 label naked neck birds (Hubbard JA57 hybrid) were assigned, at 21 days age, four experimental groups (6 replicates/treatment, 10 chickens/replicate), created according sex (M/F) provision a 10% dietary supplementation (control males, control females, females), raised until 82 age. We performed behavioural observations, tonic immobility test, an avoidance distance (AD) test. assessed feather damage cleanliness, hock burn, footpad dermatitis, skin lesion scores, determined concentration excreta corticosterone metabolites (ECM) heterophile lymphocyte heterophile/lymphocyte (H/L) ratio. observations demonstrated increased physical foraging activity ( p < 0.05) administered compared with C ones, providing valuable data explorative recreational behaviour genotype. results also evidenced usefulness fear reducer those receiving supplement moved closer operator during AD test 0.01). No injuries or observed birds, regardless whether they received not. ECM unaffected by supplementation, while H/L ratio higher than ones = 0.050). In conclusion, could constitute powerful tool for improving life quality chickens. Further required clarify stress modulation role poultry production.

Abstract Background This study aimed to evaluate the effects of Hermetia illucens (Black soldier fly-BSF) and Tenebrio molitor (Yellow mealworm-YMW) live larvae as a new nutritional model on duck’s gut health, considering histomorphometry, mucin composition, cytokines transcription levels, microbiota. A total 126, 3-days-old, females Muscovy ducks were randomly allotted three dietary treatments (6 replicates/treatment, 7 birds/pen): (i) C: basal diet; (ii) BSF: C + BSF larvae; (iii) YMW: YMW larvae. administered top diet, based 5% expected daily feed intake. The weight, average gain, intake conversion ratio evaluated for whole experimental period. On day 52, 12 ducks/treatment (2 birds/replicate) slaughtered samples duodenum, jejunum, ileum, spleen, liver, thymus bursa Fabricius collected histomorphometry. Mucin composition was in small intestine through histochemical staining while jejunal MUC-2 levels by rt-qPCR. Cecal microbiota also analyzed means 16 S rRNA gene sequencing. Results Birds’ growth performance histomorphometry not influenced with proximo-distal decreasing gradient from duodenum ileum ( p < 0.001), respecting physiological development. intensity expression did vary among treatments, even though increased according normal mucus physiology 0.001). Regarding local immune response, IL-6 higher group when compared other groups = 0.009).

Conclusions use impair development ducks, slightly improved intestinal status enhancing regulatory cytokine increasing minor Operational Taxonomic Units (OTUs) involved short-chain fatty acids production.
