Variable importance in projection (VIP) scores for differential metabolites in rumen fluid (A) and serum (B) of Korean native goat’s under optimum temperature period (OTP) and high temperature period (HTP) conditions (n = 10). The selected metabolites were those with VIP score > 1.5. Heat map with red or blue boxes on the right indicates high and low abundance ratio, respectively, of the corresponding rumen fluid and serum metabolites in OTP and HTP conditions. The VIP score was based on the partial least square-discriminant analysis model.
