“…When the birds were again given water ad libitum, the rectal temperature increased steadily to 106.0 by the end of the sixth day. Haller and Sunde (1966) observed a temporary drop of body temperature in poults after allowing the birds to drink water, but the temperature soon returned to normal. Changes in the ECG were detected as early as 24 hours after the start of water deprivation.…”

This investigation was carried out on LO white leghorn chickens, lO-lImon ths old during their laying period. BeJoı'e water deprivation, PC V, total serum cholesterol, body weight and temperature of the chickens to whiclı normal Jeed and ,vater had been given were measured. Af ter these measurements were taken the chickens were deprived of water but normal Jeeding continued. The measurements were repeated on day 6 of water deprivation. BeJore water deprivation PVC was 28. ı %, total serımı cholestef'ol , 148.3 mg / 100 ml, body weight 1.622 kg and the body temperature 40.96 oc. On day 6 of water deprivation these values were 35.9 %, 202.7 mg / 100 ml, 1.410 kg and 40.71 oC respectively. A more detailed look at the results shows that the increase in PCV and total serum cholesterol and the decrease in body weight was signijicant at a level of P

“…It is likely that this increase in adrenocortical activity represents a stress response (Freeman, 1971;Siegel, 1971;Harvey e. al. 1980;Edens, 1983), since water deprivation results in a reduction of food intake, loss of body weight and ultimately in death (Haller & Sunde, 1966;Leeson et al 1976;Hill et al 1979). Although water deprivation has been reported to have little or no effect on cortico¬ sterone secretion in adult hens (Beuving & Vonder, 1978), it is less stressful in adults because water con¬ sumption per unit weight normally decreases with age, as does water turnover and the proportion of intraand extracellular water (Leeson et al 1976).…”

“…4), especially as alimentary factors are thought to provide negative feedback for drinking be¬ haviour (Gentle, 1979). The rebound in adrenocortical activity after the injection of water may also be related to their fasted state ), or possibly result from water intoxication caused by the dilution of electrolytes in the body and subsequent changes in tissue cells (Haller & Sunde, 1966;Leeson et al 1976). Although water deprivation is stressful (Freeman, 1971;Leeson et al 1976) rapid rehydration can also cause distress and even result in death (Marsden, McKee & Crandall, 1965;McFarland & Wright, 1969).…”

The deprivation of drinking water for 30 h resulted in increased corticosterone concentrations in the plasma of 8- to 10-week-old chickens. When water-deprived birds were allowed to drink ad libitum the corticosterone concentration declined within 45 min, to the level in hydrated controls, and remained suppressed thereafter. Similar reductions in the corticosterone concentrations were also observed in water-deprived chicks which were allowed to drink for only 5 min, 1 min or 5 s. The involvement of visual stimuli in mediating this adrenocortical response was demonstrated by a comparable decline in the corticosterone concentration in water-deprived birds which were presented with water but not allowed access to it. Non-visual stimuli also appeared to be causally involved in the adrenocortical suppression after drinking, since the intraperitoneal injection of tap water (40 ml per bird) also resulted in a lowering of the corticosterone level. However, in the absence of appropriate reinforcement from metabolic stimuli, a rebound in the corticosterone concentration was observed in birds prevented from drinking, in birds unable to satiate their thirst and in birds rehydrated (orally or intraperitoneally) without feeding. These results demonstrate adrenocortical suppression in water-deprived chickens after free access to food and water and the involvement of visual and non-visual stimuli in mediating this response. The maintenance of adrenocortical suppression is dependent upon metabolic stimuli associated with food and water intake.
