Fig 1. Nutritional and Vital Data.

Fig 1

(A) Temperature humidity index (THI, solid or dashed lines), and dry matter intake (DMI; dotted lines; given as mean of both heat-stressed (HS, red) and pair-fed groups (PF, blue), respectively) during the six days of P1 and P2 and the transition day (TD). Effects of HS and PF on (B) daily milk yield, (C) rectal temperatures, (D) respiratory rate, (E) heart rate and (F) Water intake/DMI. In experimental period 1 (P1) all animals were kept at thermoneutral conditions (THI = 59.7) with ad-libitum feeding for six days. During period 2 (P2), HS cows (red lines) were heat-stressed (THI = 76.1), whereas PF cows (blue lines) were pair-fed in thermoneutrality (THI = 60.0) for six days, once ante partum (ap, dashed lines) and again post-partum (pp, solid lines). All data given as mean ± SEM; for P1 the mean of the last days of period 1 is given in Fig 1B-F as used for baseline correction; numbers of animals analyzed per group: HSap n = 7, PFap n = 6, HSpp n = 6, PFpp n = 6.
