    Niacin alters ruminal microbial composition and metabolites in sheep fed a high-concentrate diet by Zhiqiang Cheng, Jiancheng Liu, Yingying Yu, Wentao Liu, Xiaobin Li, Fengming Li, Changjiang Zang, Kailun Yang

    Published 2025-01-01
    “…The concentrations of NH3-N (p &lt; 0.01), propionate (p &lt; 0.01), and butyrate (p &lt; 0.05) in the NA group were significantly higher than those in the CON group. (3) Compared to the CON group, the ruminal pyruvate content in the NA group was significantly increased at 0 h before feeding (p &lt; 0.05), and lactic acid (p &lt; 0.05) was significantly decreased at 1 and 3 h after feeding, lactate dehydrogenase activities was significantly decreased (p &lt; 0.01) at 3 and 5 h after feeding. (4) The number of specific operational taxonomic units (OTUs) in the CON and NA groups were 26 and 37, respectively, for a total of 1,178 OTUs; principal coordinate analysis (R2 = 0.172, p-value = 0.007) and non-metric multidimensional scaling (stress = 0.1646) results showed that the two groups of samples were significantly separated. (5) The species distribution bar graph shows that at the phylum level, the relative abundances of Bacteroidetes, Firmicutes, and Proteobacteria were 43.70, 36.25, and 12.77%, respectively. (6) Orthogonal projection to latent structure-discriminant analysis results showed that the two groups of samples were clearly separated in the positive and negative ionization modes, with R2Y and Q2Y values of 0.705, 0.857, 0.695, and 0.28, respectively. …”
