| 1 | Nutritional effects of the dietary inclusion of partially defatted Hermetia illucens larva meal in Muscovy duck显示文摘Background: The present work is aimed at evaluating the effect of different inclusion levels of a partially defatted black soldier fly(Hermetia illucens,L.;HI) larva meal for ducks.A total of 192 female 3-day-old Muscovy ducklings(Cairina moschata domestica,Canedins R71 L White,Grimaud Freres Selection,France) were divided into 4 groups,assigned 4 different dietary treatments(6 replicates/treatment and 8 birds/replicate) and reared from 3 to 50 days of age.HI larva meal was included at increasing levels(0,3%,6% and 9%,HI0,HI3,HI6 and HI9,respectively) in isonitrogenous and isoenergetic diets formulated for 3 feeding phases: starter(3–17 days of age),grower(18–38 days of age) and finisher(39–50 days of age).The growth performance and apparent total tract digestibility were evaluated during the trial using titanium dioxide as an inert marker(0.3% of inclusion).At 51 days of age,two birds per pen were slaughtered and histomorphological investigations were performed.Results: The live weight and average daily gain showed a quadratic response to increasing HI meal in the grower period(minimum corresponding to the HI6 group).No effects of dietary inclusion levels were observed for the daily feed intake or feed conversion ratio.The apparent dry matter and organic matter digestibility were not affected by the dietary treatment.A linear decrease was observed for the crude protein apparent digestibility in the starter period(minimum for the HI9 groups).The ether extract apparent digestibility increased linearly during the grower and finisher periods(minimum for the HI0 group).The morphometric indices were not influenced by the dietary treatments.Conclusions: The inclusion of up to 9% of HI partially defatted larva meal in the diet of ducks did not cause any effect on growth performance,as well as the apparent digestibility.Moreover,dietary HI inclusion preserved the physiological intestinal development. | Marta Gariglio Sihem Dabbou Ilaria Biasato Maria Teresa Capucchio Elena Colombino Fuensanta Hernandez Josefa Madrid Silvia Martinez Francesco Gai Christian Caimi Sara Bellezza Oddon Marco Meneguz Angela Trocino Riccardo Vincenzi Laura Gasco Achille Schiavone | 2019 | Journal of Animal Science and Biotechnology2019，10，3： | 12 |
| 2 | Dietary inclusion of a partially defatted black soldier fly(Hermetia illucens)larva meal in low fishmeal-based diets for rainbow trout(Oncorhynchus mykiss)显示文摘Background:Recent investigations highlighted that Hermetia illucens(BSF)larva meal can be a valuable alternative protein source for aquafeed production.In this study,in substitution of fishmeal,we used increasing inclusion levels of a partially defatted BSF larva meal in low fishmeal-based diets for rainbow trout(Oncorhynchus mykiss Walbaum)and we evaluated the related implications in terms of growth performance,physical characteristics,proximate and fatty acid(FA)compositions of the fillets,gut and liver histology,and diet digestibility.In a 131-day trial,576 fish(100.1±9.29 g)were randomly allotted to 24 tanks(24 fish/tank,4 replicates/treatment).Six experimental diets were produced to have partial replacement of fishmeal(0,10%,20%,30%,40%and 50%)by increasing levels of BSF meal(0%[BSF0],3%[BSF3],6%[BSF6],9%[BSF9],12%[BSF12]and 15%[BSF15]on as fed basis,respectively).Results:No differences were observed among the treatments for all the considered growth performance parameters.The viscero and hepato-somatic indexes showed significant differences among the treatments,with the highest values observed in the BSF15 group.No differences were recorded in terms of fillet’s physical characteristics,dry matter(DM),crude protein(CP)and ether extract(EE)contents.Total saturated and monounsaturated FA increased,while polyunsaturated FA(particularly n-3 FA)decreased while increasing the HI meal inclusion in the diet.Histopathology of liver and gut was not affected,whereas,in posterior gut,villi were higher in BSF6 and BSF9 compared to BSF3 fish.The apparent digestibility of DM,CP,EE and gross energy did not vary among the treatments.Conclusions:These results suggest that a partially defatted BSF meal could be included up to 15%in low fishmeal-based diets for rainbow trout with no adverse effects on growth performance,fillet’s physical characteristics,gut and liver health,and diet digestibility.On the contrary,the fillet FA composition worsened while increasing the level of BSF meal in the diet. | Christian Caimi Ilaria Biasato Giulia Chemello Sara Bellezza Oddon Carola Lussiana Vanda Maria Malfatto Maria Teresa Capucchio Elena Colombino Achille Schiavone Francesco Gai Angela Trocino Alberto Brugiapaglia Manuela Renna Laura Gasco | 2021 | Journal of Animal Science and Biotechnology2021，12，4： | 3 |

| 10 | Effects of dietary Hermetia illucens meal inclusion on cecal microbiota and small intestinal mucin dynamics and infiltration with immune cells of weaned piglets显示文摘Background: The constant interaction between diet and intestinal barrier has a crucial role in determining gut health in pigs. Hermetia illucens(HI) meal(that represents a promising, alternative feed ingredient for production animals) has recently been demonstrated to influence colonic microbiota, bacterial metabolite profile and mucosal immune status of pigs, but no data about modulation of gut mucin dynamics are currently available. The present study evaluated the effects of dietary HI meal inclusion on the small intestinal mucin composition of piglets, as well as providing insights into the cecal microbiota and the mucosal infiltration with immune cells.Results: A total of 48 weaned piglets were randomly allotted to 3 dietary treatments(control diet [C] and 5% or10% HI meal inclusion [HI5 and HI10], with 4 replicate boxes/treatment and 4 animals/box) and slaughtered after61 days of trial(3 animals/box, 12 piglets/diet). The cecal microbiota assessment by 16 S r RNA amplicon based sequencing showed higher beta diversity in the piglets fed the HI-based diets than the C(P < 0.001). Furthermore,the HI-fed animals showed increased abundance of Blautia, Chlamydia, Coprococcus, Eubacterium, Prevotella,Roseburia, unclassified members of Ruminococcaceae, Ruminococcus and Staphylococcus when compared to the C group(FDR < 0.05). The gut of the piglets fed the HI-based diets showed greater neutral mucin percentage than the C(P < 0.05), with the intestinal neutral mucins of the HI-fed animals being also higher than the sialomucins and the sulfomucins found in the gut of the C group(P < 0.05). Furthermore, the piglets fed the HI-based diets displayed lower histological scores in the jejunum than the other gut segments(ileum [HI5] or ileum and duodenum [HI10], P < 0.05).Conclusions: Dietary HI meal utilization positively influenced the cecal microbiota and the small intestinal mucin dynamics of the piglets in terms of selection of potentially beneficial bacteria and preservation of mature mucin secretory architecture, without determining the development of gut inflammation. These findings further confirm the suitability of including insect meal in swine diets. | Ilaria Biasato Ilario Ferrocino Elena Colombino Francesco Gai Achille Schiavone Luca Cocolin Valeria Vincenti Maria Teresa Capucchio Laura Gasco | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 1 |
| 11 | Dried fruit pomace inclusion in poultry diet:growth performance, intestinal morphology and physiology显示文摘Background: Fruit pomaces are by-products rich in polyphenol compounds and dietary fiber. They seem to play an important role in regulating the gut microbiota, morphology and physiology. The aim of this study was to assess whether apple(A), blackurrant(B) or strawberry(S) pomaces could be suitable ingredients in broiler diets and their effect on gut health. A total of 480 male broilers were randomly allotted to 8 dietary treatments with lower(3%-L) or higher(6%-H) dietary fiber content: two control groups(CL/CH), two A diets(AL/AH), two B diets(BL/BH), two S diets(SL/SH). Diet and fruit pomaces were chemically analyzed to assess polyphenol concentration and fibre fraction content. After the evaluation of growth performance, 6 birds/group were slaughtered at 35 days of age. Morphometric and histopathological investigations were performed on duodenum, jejunum and ileum.Excreta were collected to perform microbiota evaluation by 16 S DNA sequencing. Weight, viscosity, enzymatic activity, short chain fatty acid(SCFAs) and ammonia concentration were determined in ileum and/or ceca content.Results: A pomace and A diets showed the lowest polyphenol content and the highest content of soluble fibre fraction. No significant differences were observed for growth performance, gut morphometry and histopathology(P > 0.05). Dietary fruit pomace inclusion increased the weight of ileum and ceca and the ileum digesta viscosity(P < 0.05). In the ileum, A and S groups showed lower bacterial α-glucosidase activity than C groups. Moreover,small intestine SCFAs concentration was higher in fruit pomaces diets(P < 0.05). In ceca, B and S groups showed lower ammonia concentration and higher SCFAs than C. Dietary treatments also influenced the activity of α-glucosidase, α-galactosidase, β-galactosidase β-glucuronidase and xylase. Regarding microbiota, at phylum level,Firmicutes were differentially abundant across treatment(maximum for C and minimum in S, FDR > 0.05). At genus level, an increase of Weissella in AH and Erwinia in S/B diets, as well as a decrease of Lactobacillus in all fruit pomace groups were recorded(P < 0.05).Conclusions: Fruit pomaces could be suitable ingredients in poultry nutrition even if further studies are needed to better understand which doses is more recommended to avoid negative effects on gut microbiota. | Elena Colombino Ilario Ferrocino Ilaria Biasato Luca Simone Cocolin Daniel Prieto-Botella Zenon Zduńczyk Jan Jankowski Joanna Milala Monika Kosmala Bartosz Fotschki Maria Teresa Capucchio Jerzy Juśkiewicz | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 1 |

| 15 | Does the provision of live black soldier fly and yellow mealworm larvae improve Muscovy duck welfare?显示文摘Background The provision of environmental enrichments to Muscovy ducks could reduce the expression of the aggressive behaviors.The aim of the present study was to evaluate the effects of black soldier fly(BSF)and yellow mealworm(YM)live larva provision on Muscovy duck performance,excreta corticosterone metabolites(ECM),behavior,and blood parameters.Methods A total of 1263-day-old female Muscovy ducklings were allotted to 18 pens(6 replicates/treatment,7 birds/pen)and assigned to 3 experimental treatments:a control group fed commercial feed,and two experimental treatments fed commercial feed plus the 5%(based on the expected daily feed intake,as fed basis)of BSF and YM live larvae(BSF and YM groups,respectively).A two-phase feeding program was applied:starter(from 3 to 31 days of age)and grower-finisher(from 32 to 55 days of age).The live weight,average daily gain,average daily feed intake,and feed conversion ratio were calculated.Larva consumption times were collected,and video recordings were performed during 3 periods(P)each day:the hour before(P1),during(P2),and after(P3)the larva administration.ECM were evaluated at 3,31,and 55-day-old.Finally,the total red and white blood cell counts,serum proteins,lipids,and liver and renal function serum enzymes were evaluated on 12 birds/treatment.Results The experimental treatment did not affect the growth performance of the birds(P>0.05).Larva consumption times were always similar between the two insect species,except at 14–18 days of age,were BSF larvae were consumed faster than YM larvae(P<0.001).The birds showed less walking activity during P2,and preening behavior increased in YM birds during P3.The C birds increased the attack behavior over the weeks(P<0.05).During weeks 1–3 the YM group reduced the attack frequency(P1>P3;P<0.05).Finally,the provision of live BSF and YM larvae significantly reduced the ECM at 55 days of age and the heterophil to lymphocyte ratio(P<0.05).Conclusions Live BSF and YM larva supplementation in Muscovy duck improves duck welfare,without impairing birds'growth performance. | Marta Gariglio Sihem Dabbou Manuela Renna Ilaria Biasato Sara Bellezza Oddon Marco Meneguz Raul Daniel Miazzo Stefania Bergagna Elena Colombino Elisabetta Macchi Achille Schiavone | 2024 | Journal of Animal Science and Biotechnology2024，15，1： | 0 |
