In the RE group, serum urea nitrogen content significantly decreased ( P = 0.013), and there was a decreasing trend in cholesterol ( P = 0.056) and low-density lipoprotein content ( P = 0.056).
Additionally, the RE group showed a trend of higher milk fat content compared to the CON group ( P = 0.071) ( Table 2 ).
In rumen fermentation, the content of butyric acid ( P = 0.035) in RE group was significantly increased, while valeric acid ( P = 0.080) content had an increasing trend.
