Project description:To investigate effects of long-term intake of RPS on gene expression in the colon and liver of pigs,thirty-six Duroc × Landrace × Large White growing barrows were randomly allocated to corn starch (CS) and RPS groups. Each group consisted of six replicates (pens), with three pigs per pen. Pigs in the CS group were offered a corn/soybean-based diet, while pigs in the RPS group were put on a diet in which 230 g/kg (growing period) or 280 g/kg (finishing period) purified corn starch was replaced with purified RPS during a 100-day trial. Liver transcriptomic results showed that the expression of CD36, CPT1B and ACADM was down-regulated, while AGPAT4, GPAT, FABP1 and FABP3 were up-regulated by the RPS diet, indicating a decrease in fatty acid intake and synthesis, and an increase in fatty acid oxidation and glycerophospholipid synthesis.Analysis of the colonic transcriptome profiles revealed that the RPS diet changed the colonic expression profile of the host genes mainly involved in immune response pathways. RPS significantly increased proinflammartory cytokine IL-1? gene expression and suppressed genes involved in lysosome. Thirty-six Duroc × Landrace × Large White growing barrows (70 days of age, 23.78 ± 1.87 kg) were randomly allocated to two groups, each group consisting of three pigs per pen, and six replicates. Pigs in the control group were offered a corn/soybean-based diet, while 230 g/kg purified corn starch (CS) was replaced with purified RPS in the RPS diet group. Diets were formulated according to the nutrient requirements of the National Research Council (1998). When animals reached the age of 120 days, diets were adapted to the nutrient requirements of the animals (finishing diet) and the amount of purified starch increased to 280 g of CS or RPS per kilogram of feed. Pigs had unlimited access to feed and water throughout the experimental period, which consisted of two 50-day trials in which the pigs consumed the growing diet (days 0-50) and finishing diet (days 51-100), respectively. On day 100, one pig from each replicate that met the target slaughter weight (105 to 110 kg) was slaughtered. The liver and colonic mucosa tissues were collected and preserved in liquid nitrogen for gene expression analysis.

Project description:The aim of this study was to investigate whether long term intake of pea fiber would improve colonic barrier, bacterial profile and alter colonic gene expression using DNA microarray. Fifty weaned pigs were randomly allocated into 2 groups receiving control and fibrous diet with inclusion of pea fiber from weaning age until d 160. The two diets had similar nutrient levels. Pigs fed pea fiber diet (PF diet) had markedly decreased overall average daily feed intake (ADFI) and Feed:Gain in growing and finishing period (P<0.05). In addition, long term intake of PF diet induced deeper crypt (+50 %, P<0.05), increased protein expression of colonic mucin and sIgA (+13～16 %, P<0.05). Resulting from the increased lactobacillus content (P<0.05), moreover, pigs fed PF diet had significantly higher concentration of colonic total short chain fatty acid (SCFA) and acetic acid. DNA microarray results indicated that feeding PF diet induced alterations in the expression of colonic cancer, immune response and lipid metabolism-related genes, as well as genes involved in signal pathway such as intestinal immune network for IgA production, PPAR signaling pathway and nutrient metabolism-related pathways. Collectively, our results suggested that long term intake of PF diet would improve colonic health via altering colonic bacteria profile, colonic barriers, immune and metabolism related protein or gene expressions. A total of 50 weaned pigs (Duroc×Landrace×Yorkshire, initial body weight: 7.2±0.5 kg) were randomly allocated to 2 groups with 5 pens each group and 5 pig each pen. Pigs were fed control (Control) and fibrous diets (10～20 % inclusion of pea fiber, PF) from weaning at 28 day to 160 day-old-age, which is subjected to phase feeding by weaning diet (weaning to d 30 post-weaning), growing diet (d 30～90 postweaning) and finishing diet (d 90～160 postweaning) according to their physiological stage. At d 160 postweaning, four pigs each group were selected to be slaughtered for collection of colonic tissues and DNA microarray was applied to the colonic tissues for analysis of gene expression.

Project description:Background: monogastric feeding is dependent on conventional feedstuffs such as corn and soybean meal. However, these are increasingly expensive and environmentally unsustainable. Therefore, there is an increasing interest in high quality and sustainable alternative feedstuffs, namely microalgae. Chlorella vulgaris is one of such alternatives, with a high level of crude protein and bioactive compounds. However, its recalcitrant cell wall hinders the digestive process. CAZyme supplementation is a possible solution to overcome such a problem. The objective of this work was to evaluate the effect of a 5% dietary C. vulgaris (CV) and enzymatic supplementation (CV+R – Rovabio® Excel AP; CV+M – four CAZyme mix) on muscle transcriptome and proteome of finishing pigs in an integrated approach. Results: there were no differences concerning the live pig production performance. Pigs that were fed with the microalga had increased deposition of n-3 PUFA, including C20:5n-3 (EPA) in the muscle. Control pigs increased the abundance of contractile apparatus (e.g. MYH1, MYH2, MYH4) and energy metabolism (e.g. CKMT1, NDUFS3) proteins, demonstrating increased nutrient availability. Moreover, they had increased abundance of SCD, characteristic of increased glucose availability via the activation of SREBP-1c and ChREBP. CV and CV+R pigs upregulated proteolytic and apoptotic genes (e.g. BAX, DDA1), whilst increasing the abundance of glucose (UQCRFS1) and fatty acid catabolism (ACADS) proteins. CV+R pigs upregulated ACOT8 and SIRT3 genes as a response to reduced nutrient availability, to maintain energy homeostasis and oxidative status. The CV+M pigs showed the least number of significant differences in both omics platforms. Conclusions: the four-CAZyme mix designed to degrade the microalgal cell wall was efficient in re-establishing the muscle metabolism, mitigating the otherwise negative effects of microalga incorporation in the diet.

Project description:This study was performed to determine the effects of dietary fat sources, i.e., beef tallow, soybean oil, olive oil and coconut oil (each 3% in feed), on the growth performance, meat quality and gene expression in growing-finishing pigs. The results of this study indicate that the type of dietary fat affects fatty acid composition and insulin signaling-related gene expression in the longissimus dorsi muscle of pigs.

Project description:The increasing aquaculture production volumes have caused an escalating demand for alternative protein feed ingredients. Agro-industrial by-products such as sunflower meal are relatively abundant and cheap, but the inclusion levels are limited due to the presence of antinutritional factors and fiber. Solid state fermentation is a processing method with the aim of reducing the content of fiber and antinutritional factors and improving nutritional value in plant protein raw materials. In this study, Atlantic salmon (Salmo salar) at two commercial-like fish farms were fed diets containing 5% non-fermented sunflower meal (as a control diet) and two experimental diets with 5% or 10% fermented sunflower meal. The field trial lasted for eight and 11 months in a coastal and fjord location, respectively with the aim of comparing the effect of fermented diets on growth performance, gut microbiota, distal intestine histology and gene expression of Atlantic salmon under different environmental conditions. The findings revealed that diets with fermented sunflower meal sustained growth performance, improved intestinal health by reducing the prevalence of prominent inflammation and ectopic goblet cells and promoted gut lactic acid bacteria Lactiplantibacillus and Lactobaccilaceae after long-term feeding. Our results suggest that fermented sunflower meal is suitable as a protein source for Atlantic salmon when included at a level of up to 10% in the diet.
