Observations on the Body Temperature of Dry Cows

about 8 a. m. the cow was offered water, but she refused to drink. 
At 7.48 a. m. the cow was lying; during all other readings she was stand¬ 
ing. At 9.25 a. m. the reading was taken immediately after the cow had 
urinated. At 7.48 a. m., 3.10 p. m., 5 p. m., and 5.30 p. m. the read-

8.06 a. m. to 4.30 p. m. standing; 8.12 a. m. immediately after defecating; 8.30 a. m. drank 29.4 kgm. of 
water at 52°F.; 10.12 a. m. immediately after urinating and defecating; 2.30 p. m. after defecating. 
ings were taken immediately after defecation. From 5 p. m. to 5.3° 
p. m. the cow was eating. The results are represented by figure 7. . 
The striking feature of these curves is that they are very much smoother 
than the preceding ones. The drop in temperature in the morning is 
lacking, apparently, because the cow did not drink any water. The 
curves show instead a very gradual and slight fall in temoerature fill

Fig. 7.—Variations in body temperature of cow 885 on December 2, 1919, 7.48 a. m. to 5.30 p. m. At 7.48 
a. m. lying and immediately after defecating; 8.36 a.m. to 5.30 p. m. standing; cow drank no water; 9.25 
a. m. immediately after urinating; 3.10 p.m. immediately after defecating; 5 p. m. immediately after 
defecating; 5 p. m. to 5.30 p. m. eating; 5.30 p. m. immediately after defecating. 
2 p. m., and from that time a gradual rise. The vaginal curve is lower 
than the rectal and runs almost parallel with it, not meeting it at any 
point. 
The highest rectal temperature obtained was 102.4 0 F. at 5.30 p. m., 
while the lowest was 101.6 0 at 2 p. m. The highest vaginal temperature 
obtained was 101.9 0 at 5.30 p. m., while the lowest was 101.5 0 at 2 p. m.
