The MRT of digesta in various GIT segments, measured using similar methodology, was related to dietary PP: rheological parameters (extract viscosity and solid phase moduli plus linear viscoelastic range) and water-binding capacity (WBC). For each GIT segment and digesta phase, PP were selected as independent variables to include in prediction models after a correlation and multicollinearity analysis, followed by MaxR and stepwise variable selection methods. Subsequently, multiple and single regression analyses were performed, including selected PP as predictor variables. The MRT of solid (MRT_solids) and liquid (MRT_liquids) digesta, and digesta phase segregation were predicted using model equations with (1) selected PP (full model), (2) WBC only, and (3) extract viscosity only; and calculated vs. observed values were compared. Coefficients of determination (R²) were used to select the best model to predict digesta MRT by GIT segment. Dietary PP were capable of predicting digesta phase segregation in the stomach (R² = 0.56), largely explained by WBC (R² = 0.51), and MRT_liquids (R² = 0.26), explained by WBC and rheological parameters.

Regarding lipid metabolism, BVP (1.0–8.0 g/kg) decreased the triglyceride (<em>P</em> &lt; 0.05) and total cholesterol (<em>P</em> &lt; 0.05) levels in the liver and improved hepatic lipid metabolism by upregulating the expression of lipid transport (hormone-sensitive lipase and lipoprotein lipase) and lipid metabolism (fatty acid transport protein and microsomal triglyceride transfer protein) genes (<em>P</em> &lt; 0.05). With regard to inflammation, BVP (0.5–4 g/kg) modulated the expression of inflammatory factors (interleukin-8, transforming growth factor-β, and interleukin-10; <em>P</em> &lt; 0.05) to improve the inflammatory response. Collectively, these results suggested that dietary BVP at a level of 2.0 g/kg can help improve growth performance, antioxidant capacity, and inflammatory response and reduce lipid deposition in the liver of largemouth bass.</div></div>","PeriodicalId":7861,"journal":{"name":"Animal Feed Science and Technology","volume":"321 ","pages":"Article 116236"},"PeriodicalIF":2.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143218587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
