“…McLean et al (1984) found that rectal temperature measured once daily was the same in beef cows housed at 18°C as in cows housed outside at temperatures ranging from 0 to -30°C. Webster et al (1970) found no differences in rectal temperatures measured weekly in growing beef calves raised indoors (20°C) compared to calves raised outdoors in temperatures ranging from 14 to -29°C. In contrast, Young (1975b) found that rectal temper- For personal use only.…”

“…Cold environments induce physiological responses that increase maintenance energy requirements (Christopherson and Kennedy 1983;Delfino and Matheson 1991;Scott and Christopherson 1993;Young 1981). The detrimental effects of prolonged cold exposure on the growth rate and feed requirements of beef cattle in western Canada have been well documented (Webster et al 1970;Milligan and Christison 1974;Young 1975aYoung , 1981Delfino and Matheson 1991). However, as noted by DeDios and Hahn (1994), the majority of thermoregulatory studies have examined the effects of long-term heat (summer) or cold (winter) stress, rather than the transition to warm (spring) or cold (autumn) weather.…”

“…The recovery from an initial over-reaction in Ts and RR on change of environment is typical of acclimatization to prolonged heat or cold stress (Webster et al 1970;Young 1975 Generally there was no significant difference in the 18'C environment or in the cold between the first and second measurement day, nor was the interaction DA ever significant. The exceptions were the marginally significant day effects surprisingly found for Tr during the cold exposure and for M during the l8"C exposure treatments.…”

“…Coat thickness was measured on eight cows (four of each breed) taken at random at the end of the experiment. An engineer's depth gauge was used to measure the depth of the coat at several sites on both sides of the cow in three horizontal lines to give a minimum of 24 measurements per cow with at least one measurement from the neck, the top of the front leg and the middle section of the rear leg (Blaxter and Wainman, 1964;Webster et al, 1970).…”
