Before And After

An attempt was made to determine the effect of orally ingested acetylsalicylic acid (ASA) in moderate amounts for varying periods of time, on temperature response of ten healthy young men walking on a power-driven treadmill with a work load of approximately 6 mets. Three experiments were conducted, ranging from one dose of 1.8–2.4 g ASA to 3.6–4.8 g/day in divided doses for 48 hr, and the same amount in divided doses for 5–7 days, the dose in the first experiment and the last dose in those following being given 1frac12–2 hr before exercise. Rectal temperature was measured at rest, during exercise, and for 20–45 min of recovery. Blood levels of salicylate were determined, hematocrits were recorded, and total proteins were determined; each subject was weighed before and after exercise. It was found that rise in body temperature was not modified by ASA in any of the various dosages, nor was significant hemodilution of the blood caused. Suggestive, but not conclusive, evidence emerged indicating that salicylates accelerate the early stages of the fall in body temperature after exercise. Submitted on October 5, 1961

Near Term

Rats have an attenuated or absent febrile response to exogenous pyrogen (e.g., bacterial endotoxin) near term of pregnancy. With the aim of providing insight into possible mechanism(s) of the altered febrile response to exogenous pyrogen, experiments have been carried out on 67 time-bred Sprague-Dawley rats to investigate the febrile response to endogenous pyrogen [i.e., interleukin-1 beta (IL-1 beta)]. On day 13 of gestation, intravenous injection of IL-1 beta produced a significant increase in body temperature with a latency of approximately 30 min and a duration of approximately 120 min. In contrast, on days 17 and 21 of gestation as well as on the day of delivery, intravenous injection of IL-1 beta produced significant decreases in body temperature. Thus rats do not develop fever in response to endogenous pyrogen near term of pregnancy but rather become hypothermic. The mechanism of the altered body temperature response to exogenous pyrogen as pregnancy proceeds remains unknown. We speculate, however, that it most likely lies downstream from the formation of endogenous pyrogen.

Plasma Vasopressin

Several physiological variables were measured after endotoxin administration in the rat to examine the relationship between these variables. Rats responded to endotoxin with a biphasic body temperature response, an initial decrease and a subsequent increase in body temperature. Plasma vasopressin and oxytocin levels increased markedly after endotoxin administration. Diarrhea occurred in some animals. There was a strong negative correlation between increase in body temperature and base-line body temperature, and weak correlations between body weight and plasma vasopressin release and between base-line body temperature and minimum body temperature reached. Plasma vasopressin and oxytocin levels were correlated if samples from all time points were analyzed together, whereas they were not correlated if data from each time point were analyzed separately or if total peptide release for each rat was evaluated. These data suggest similar regulation for the release of vasopressin and oxytocin, that is, release by a common stimulus, but the magnitude of release of vasopressin and oxytocin appears to be independent, probably reflecting differences in synthesis and storage of these two peptides.

Temperament Trait

Previous studies have indicated that cattle with more excitable temperaments exhibit an increased stress response. The objective of this study was to investigate the relationship between temperament traits, handling, and stress-induced hyperthermia (SIH) in beef cattle. Rectal temperatures (TREC, °C) of 60 purebred Angus cattle (30 heifers, 30 steers; 235.2 ± 5.11 kg) were recorded at 20 s intervals from 30 min prior to handling until two hours post handling. All cattle were exposed to a standardized handling procedure consisting of (i) being restrained in a weighing box for 30 s; (ii) being held within the crush for 30 s; and then (iii) being restrained in a head bail for 60 s. Cattle temperaments were evaluated via three traits: (1) agitometer score (AG); (2) crush score (CS); and (3) flight speed (FS) during the handling procedure. Agitometer scores and FS measures were used to describe an AG category (AGCAT) and an FS category (FSCAT) that were used to classify animals into three temperament categories: 1, calm; 2, intermediate; and 3, temperamental. Pearson’s correlation coefficients were used to evaluate the associations between (i) AG, CS, FS, and TREC 30 min prior to entry into the weighing box (T-30) and then at 1 min intervals between time of entry into the weighing box (T0) until 10 min post-weighing (T10); and (ii) the relationship between AG, CS, and FS. The relationship between TREC and temperament traits over the 2.5 h were modeled by using a first-order autoregressive repeated measures model. Flight speed had strong to moderate associations with TREC at T-30 (r ≥ 0.37; p ≤ 0.006) and between T0 and T10 (r ≥ 0.36; p ≤ 0.01). There were moderate associations amongst TREC between T0 and T10 and CS (r ≥ 0.31; p ≤ 0.01). A weak relationship existed with CS (r = 0.16; p = 0.16). There were no associations between AG and TREC at T-30 (r ≥ −0.15; p = 0.84) or between T0 and T10 (r ≤ 0.04; p ≥ 0.4). Rectal temperature, irrespective of sex and temperament traits, was influenced by time (p < 0.0001), and maximum TREC (39.3 ± 0.04 °C) occurred between 4 and 5.7 min after entry into the weighing box. In addition, CS (p = 0.007) influenced TREC in these cattle. There were also time × temperament trait × sex interactions with the CS (p = 0.0003) and FSCAT (p = 0.043) categories; however, time × temperament trait interactions were not statistically significant. Results from this study suggest that cattle with excitable temperaments, as evaluated by FS and CS, have a greater increase in TREC. In addition, these results suggest that a relationship exists between basal TREC and FS and CS. Together, these results highlight that temperament, as assessed by FS and CS, influences both basal TREC and the peak temperature recorded following handling but does not influence the magnitude of change in TREC post handling.

To ensure animal welfare is not compromised, virtual fencing must be predictable and controllable, and this is achieved through associative learning. To assess the influence of predictability and controllability on physiological and behavioral responses to the aversive component of a virtual fence, two methods of training animals were compared. In the first method, positive punishment training involved sheep learning that after an audio stimulus, an electrical stimulus would follow only when they did not respond by stopping or turning at the virtual fence (predictable controllability). In the second method, classical conditioning was used to associate an audio stimulus with an electrical stimulus on all occasions (predictable uncontrollability). Eighty Merino ewes received one of the following treatments: control (no training and no stimuli in testing); positive punishment training with an audio stimulus in testing (PP); classical conditioning training with only an audio stimulus in testing (CC1); and classical conditioning training with an audio stimulus followed by electrical stimulus in testing (CC2). The stimuli were applied manually with an electronic collar. Training occurred on 4 consecutive days with one session per sheep per day. Sheep were then assessed for stress responses to the cues by measuring plasma cortisol, body temperature and behaviors. Predictable controllability (PP) sheep showed no differences in behavioral and physiological responses compared with the control treatment (P &lt; 0.05). Predictable uncontrollability of receiving the aversive stimulus (CC2) induced a higher cortisol and body temperature response compared to the control but was not different to CC1 and PP treatments. CC2 treatment sheep showed a higher number of turning behaviors (P &lt; 0.001), and more time spent running (P &lt; 0.001) than the control and PP treatment groups, indicating that predictability without controllability was stressful. The behavior results also indicate that predicting the event without receiving it (CC1) was less stressful than predicting the event then receiving it (CC2), suggesting that there is a cost to confirmation of uncontrollability. These results demonstrate that a situation of predictability and controllability such as experienced when an animal successfully learns to avoid the aversive component of a virtual fence, induces a comparatively minimal stress response and does not compromise animal welfare.
