Table 3 The LPS, milk yield and milk composition in the dairy cows fed the low-concentrate (LC) and high-concentrate (HC) diets

From: Lipopolysaccharide derived from the rumen down-regulates stearoyl-CoA desaturase 1 expression and alters fatty acid composition in the liver of dairy cows fed a high-concentrate diet

  1. 1SEM = Standard error of the mean between the two groups.
  2. 2The LPS data were compared using Student’s t-test. The milk samples were compared using a paired t-test.
  3. 3The milk samples were obtained from the 1st week to the 18th week.
  4. abindicates p < 0.001; aindicates p < 0.05; bindicates p < 0.01.
