Differentially expressed genes in livers and abdominal fats between normal- and high-fat diet-fed dwarf broilers

Project description:To investigate genes involved in abdominal fat deposition and fat metabolism of broilers with dw gene, we used highthroughput sequencing to detect the differentially expressed genes in livers and abdominal fats of dwarf broilers which were fed with a normal diet and a high-fat diet, respectively. The broilers began to fed with a normal or a high-fat diet in 1-week-old. After 7 weeks, the broilers were be executed and the livers and abdominal fats were used to extracted total RNAs. Finally, the total RNAs were be sequenced used BGISEQ-500 platform.

Effects of rye inclusion in 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.

Effect of replacing soybean meal with Hermetia illucens meal on cecal microbiome, liver transcriptome and plasma metabolome of broilers

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.
