Linear models fitted to data of milk synthesis efficiency (I), 4% FCM synthesis efficiency (II), milk fat synthesis efficiency (III), and milk protein synthesis efficiency (IV), which are expressed as y , in response to concentrations of IL-1β (expressed as x ) in mammary gland venous plasma of dairy cows. I, y = −0.0022x + 1.753 (R² = 0.1183, r = −0.3439, SE = 0.1771, P = 0.0627, n = 30); II, y = −0.0033x + 2.003 (R² = 0.1606, r = −0.4007, SE = 0.2244, P = 0.0282, n = 30); III, y = −0.0153x + 8.457 (R² = 0.1678, r = −0.4096, SE = 1.026, P = 0.0246, n = 30); IV, y = −0.0066x + 5.474 (R² = 0.0795, r = −0.2820, SE = 0.6769, P = 0.1311, n = 30).
