“…28.2 and 31.9°C in the warm and the hot seasons, respectively) of ambient temperature. According to previous results reported in buffaloes (Sethi et al, 1992;Koga et al, 1999) or in pigs (Korthals et al, 1999), diurnal variation of body temperature follows that of ambient temperature, suggesting that in addition to feeding behaviour and physical activity, circadian rhythm of body temperature is affected by changes in external ambient temperature.…”

The effects of season (hot vs. warm) in a tropical humid climate, parity (primiparous vs. multiparous) and breed (Creole: CR, Large White: LW) on rectal temperature (RT) were studied for a total of 222 lactations obtained in 85 sows (43 CR and 42 LW; 56 primiparous and 166 multiparous) over a 28-d lactation, between June 2002 and April 2005. Mean daily ambient temperature was higher during the hot season than during the warm season (26.0 vs. 24.1°C) and relative humidity was high and similar in both seasons (89% on average). At farrowing, BW was lower (172 vs. 233 kg) and backfat thickness was higher (37 vs. 21 mm) in CR than in LW sows (p<0.01). During the hot season, the reduction of average daily feed intake (ADFI) was more pronounced in LW than in CR sows (-920 vs. -480 g/d, p<0.05). Rectal temperature was higher at 1200 than at 0700hr, which coincides with the maximum and the minimum values of daily ambient temperature. The daily RT increased (+0.9°C; p<0.01) between d -3 and d 7 (d 0: farrowing day), remained constant between d 7 and d 25 and decreased (p<0.01) thereafter (i.e. -0.6°C between d 25 and d 32). The average daily RT was significantly higher during the hot than during the warm season (38.9 vs. 38.6°C; p<0.01). It was not affected by breed, but the difference in RT between the hot and warm seasons was more pronounced in LW than in CR sows (+0.4 vs. +0.2°C; p<0.05). Parity influenced the RT response; it was greater in primiparous than in multiparous sows (38.9 vs. 38.7°C; p<0.01). This study suggests that thermoregulatory responses to heat stress can differ between breeds and between parities.

“…The swamp buffalo possesses only one-sixth number of sweat glands of cattle (Bos indicus) and is sparsely covered with hairs (Frisch and Vercoe, 1979), and is therefore more prone in suffering heat stress when exposed to solar radiation and denied access to a wallow (Frisch and Vercoe, 1979). The body temperature of a buffalo is slightly lower than that of a cow (Koga et al, 1999;Chikamune, 1983). The dark skin, thick epidermis and lesser density of sweat glands in buffaloes make it difficult for the buffalo to exist in extreme hot and dry conditions; thus buffaloes have developed survival mechanisms to seek water for immersion in these conditions (Thomas, 2005).…”

“…By contrast, the rectal temperature of buffaloes decreases rapidly when they are moved into the shade (Badreldin & Ghany 1952) or sprayed with water (Chikamune et al 1987), following heat stress. The results of a series of experiments that were carried out to compare thermoregulation in buffaloes with that of temperate cattle revealed that the rectal temperature of buffaloes fluctuated with diurnal changes in air temperature (Koga et al 1999 b). This fluctuation was the result of active transport of heat through increased blood flow from the core of the body to its surface .…”

In previous comparative studies of buffaloes and temperate cattle, a greater increase in rectal temperature (RT) and skin temperature (ST), and a greater decrease in haematocrit (Ht) have been observed in buffaloes than in temperate cattle with an increase in ambient temperature (AT). Our series of previous experiments suggested that great changes in RT, ST and Ht are induced in buffaloes by a marked increase in blood flow from the body core to the surface, which accelerates dissipation of heat from the skin surface. On the basis of these suggestions, the present study was undertaken to compare fluctuations in RT, ST and Ht between buffaloes and tropical cattle. Fluctuations in the aforementioned parameters, particularly RT and Ht, were greater in buffaloes than in cattle. Moreover, the correlation for RT or Ht v. AT was significant for buffaloes (r=0·33 and −0·37, respectively) but not for cattle. The correlation coefficient for ST v. AT was significant in both species, but was greater in buffaloes (r=0·63) than in cattle (r=0·56). These results demonstrate that with changes in ambient temperature, RT, ST and Ht fluctuate much more in buffaloes than in tropical cattle, as found previously for temperate cattle. Therefore, the distinctive thermoregulatory responses of buffalo are confirmed as being specific to this species.
