Project description:Despite the existence of a number of studies investigating the effect of insect meal on the growth performance of broilers, knowledge about the metabolic effects of insect meal in broilers is still scarce. Thus, the present study investigated the effect of partial replacement of soybean meal with Hermetia illucens (HI) larvae meal on the liver transcriptome, the plasma metabolome and the cecal microbiome in broilers. For the study, 72 male one-day-old Cobb 500 broilers were divided into three groups (n = 12) and fed three different diets with either 0% (HI0), 7.5% (HI7.5) or 15% (HI15) defatted HI meal for 35 d. While body weight (BW) gain, feed intake, and feed:gain ratio did not differ between groups, breast muscle weight, carcass yield and apparent ileal digestibility (AID) of 12 amino acids were higher in group HI15 than in group HI0 (P > 0.05). Indicators of α-diversity (Chao1 and Observed) in the cecal digesta were higher in groups HI15 and HI7.5 than in group HI0 (P < 0.05). The abundance of 5 families and 18 genera, all of which belonged to the Firmicutes phylum, in the cecal digesta differed among groups (P < 0.05). Concentrations of butyric acid, valeric acid and isobutyric acid in the cecal digesta were lower in group HI15 than in the other two groups (P > 0.05), whereas those of total and other short-chain fatty acids were not different between groups. Liver transcriptomics revealed a total of 70 and 61 differentially expressed transcripts between groups HI15 vs. HI0 and between groups HI7.5 vs HI0, respectively, (P > 0.05). Targeted metabolomics identified 138 metabolites, most of which were triglyceride species, being different between the three groups (FDR < 0.05). According to this study, dietary inclusion of HI larvae meal has no detrimental impact but increases breast muscle weight and carcass weight in broilers suggesting that HI larvae meal can be recommended as a sustainable alternative protein source for broilers.

Project description:An experiment was conducted to investigate the effects of dietary inclusion of rye, a model ingredient to increase gut viscosity, between 14 and 28 days of age on immune competence related parameters and performance of broiler. A total number of 960 one-day-old male Ross 308 chicks were weighed and randomly allocated to 24 pens (40 birds per pen), and the birds in every 8 replicate pens were assigned to one of three experimental diets including graded levels, 0%, 5%, and 10% of rye. Tested immune competence related parameters were composition of the intestinal microbiota, genes expression in gut tissue, and gut morphology. The inclusion of 5% or 10% rye in the diet (d14-28) resulted in decreased performance and litter quality, but in increased villus height and crypt depth in the small intestine (jejunum) of the broilers. Relative bursa and spleen weights were not affected by dietary inclusion of rye. In the jejunum, no effects on number and size of goblet cells, and only trends on microbiota composition in the digesta were observed. Dietary inclusion of rye affected expression of genes involved in cell cycle processes of the jejunal enterocyte cells, thereby influencing cell growth, cell differentiation and cell survival, which in turn were consistent with the observed differences in the morphology of the gut wall. In addition, providing rye-rich diets to broilers affected the complement and coagulation pathways, which are parts of the innate immune system. These pathways are involved in eradicating invasive pathogens. Overall, it can be concluded that inclusion of 5% or 10% rye to the grower diet of broilers had limited effects on performance. Ileal gut morphology, microbiota composition of jejunal digesta, and gene expression profiles of jejunal tissue, however, were affected by dietary rye inclusion level, indicating that rye supplementation to broiler diets might affect immune competence of the birds.

Project description:The aim of this study was to explore whether, and if so, how Bacillus subtilis KC1 can enhance the growth performance of broilers that have been adversely affected by Mycoplasma gallisepticum (MG) infection. A total of 96 1-day-old male broilers were randomly divided into 4 groups: the control group (basal diet), the MG group (basal diet + MG challenge), the Bacillus subtilis KC1 group (basal diet + Bacillus subtilis KC1 supplementation), the Bacillus subtilis KC1 + MG group (basal diet + Bacillus subtilis KC1 supplementation + MG challenge). The trial lasted 42 days, and the results showed that the MG group had significantly reduced body weight and average daily gain, as well as increased feed conversion ratio of broilers, compared to the control group. Dietary supplementation with Bacillus subtilis KC1 significantly improved the growth performance of MG-infected broilers. In addition, dietary supplementation with Bacillus subtilis KC1 significantly improved oxidative stress and inflammatory response markers, characterized by increased superoxide dismutase levels and reduced levels of malondialdehyde, interleukin-1β, and tumor necrosis factor-α. Furthermore, both metabolomics and transcriptomics analyses indicated that MG infection markedly disrupted amino acid metabolism in broilers, whereas Bacillus subtilis KC1 supplementation alleviated the abnormal amino acid metabolism caused by MG infection. These results suggested that Bacillus subtilis KC1 may alleviate the poor growth performance caused by MG infection in broilers by improving amino acid metabolism.

Project description:Single cell proteins, such as Candida utilis, are known to have immunomodulating effects in the distal intestine (DI) of Atlantic salmon, whereas soybean meal (SBM) can cause soybean meal induce enteritis (SBMIE). Inflammatory or immunomodulatory stimuli at the local level in the intestine may alter the plasma protein profile of Atlantic salmon. These changes can be helpful tools in diagnosis for fish diseases and indicators for fish health. The present work aimed to identify local intestinal tissue responses and changes in plasma protein profiles of Atlantic salmon fed C. utilis yeast, SBM, or combined diets. Fish meal (FM) based diet was used as a control diet and the six experimental diets were: FM diet with 200 g/kg C. utilis (FM200CU) and five diets containing 200 g/kg SBM together with 0 (SBM group), 25, 50, 100 or 200 g/kg C. utilis (SBM25CU, SBM50CU, SBM100CU and SBM200CU groups, respectively). Intestine morphology of fish fed FM200CU where not affected whereas SBM group presented changes characteristic of SBMIE. Low inclusion of C. utilis in SBM diet showed a modulation of immune cell populations, but did not alleviate inflammatory symptom.
