Body weight (A), live weight variation (B), total water intake (C), 3.5% FCM (D), milk lactose percent (E), milk lactose yield (F), total solids percent (G), somatic cell count (SCC; H), milk efficiency (I), ECME (J), and 3.5% ECME (K).

Cows were randomly assigned to one of four treatments at enrollment: unsupplemented thermoneutral conditions (TN-Con, n = 12), heat-stress with no organic acids and pure botanicals (OA/PB) supplementation (HS-Con, n = 12), thermoneutral conditions pair-fed to HS-Con (TN-PF, n = 12), HS supplemented with OA/PB (75 mg/kg of body weight [BW]; AviPlus R; VetAgro S.p.A., Italy; HS-OAPB, n = 10). Control cows (not supplemented with OA/PB) received a matching dose of the lipid matrix.
