“…They also reported slight increase in serum potassium from 4.00±0.07 to 4.22±1.14 mEq/l during 96 hours of water deprivation. Samara et al, (2012) observed that dehydration in goats significantly (P<0.05) increased serum concentrations of sodium and potassium and therefore serum osmolality in goat and camel was increased with parallel increased in their serum sodium concentration during dehydration period; but with smaller percentage changes in camel (6%) compared with goat (69%). Jaber et al, (2004) recorded a decrease in serum potassium concentration in Awassi sheep when subjected to intermittent watering once every 4 days.…”

The present investigation was aimed to study the effect of vitamin C on electrolyte concentrations in blood and urine in water deprived goats during summer and winter seasons. Eighteen adult male goats were selected for the experiment during both seasons.In each season, there were two treatment groups: T1 and T2 group. In T1 group, water was restricted and subdivided into three experimental periods: in period 1 (day 1 to 7), goats were adapted to the water restriction regime by limiting access to water gradually from 15 to 3 hour per day. During the second period of the experiment (day 8 to 14), animals had access to water for 3 hours/day. In the final period of the experiment (day 15 to 22), animals had access to water only every second day for 6 hours. In T2 group, the same protocol as mentioned above was followed with addition of vitamin C supplementation (180 mg/kg body weight/animal/day). In the control group (both season), water was offered ad libitum (24 hours) throughout the experimental period. Blood and urine samples were collected and concentrations of different electrolytes were estimated. In T1 group, serum and urine sodium, potassium and chloride levels showed increasing trend (P<0.05) in both seasons.Urine sodium and chloride concentrations showed increasing trend up to day 22 in both seasons in T2 group; whereas, potassium concentration showed similar trend from day 7 during winter season, but during summer concentration increased up to 7 day, then decreased. Significantly lower (P<0.05) serum and urine electrolyte values were observed in vitamin C supplemented group as compared to water deprived group in last days (14 and 22 day) of experiment.The overall summer value of serum sodium and chloride were higher as compared to overall winter values in all the groups; whereas, overall summer value of potassium was higher only in control group as compared to winter season.Overall summer value of urine sodium was higher in all groups, significant variation found in T2 group. Overall potassium concentrations in urine was significantly higher (P<0.05) in T1 in summer. Summer chloride concentrations in urine were higher in treatment groups; whereas, lower in control.Water deprivation had negative impact on electrolyte balance, which can be ameoliorated by supplementation of ascorbic acid at the rate of @180mg/kg b.wt./day.

“…Mesor and amplitude can also be viewed as indices of physiological strain. The T c amplitude is inversely correlated with energy intake (Goh et al., 2016 ; Maloney et al., 2013 ) and water intake (McCarron et al., 2001 ; Samara et al., 2012 ). The mesor and amplitude of T c decrease during pregnancy (Crew et al., 2018 ; Maloney et al., 2017 ; Trethowan et al., 2016 ) and are indicative of ovulation (Cagnacci et al., 1996 ; Crew et al., 2018 ; Lee, 2016 ) and the level of sex steroid hormones (Marrone et al., 1976 ).…”

Core body temperature (Tc) is a critical aspect of homeostasis in birds and mammals and is increasingly used as a biomarker of the fitness of an animal to its environment. Periodogram and cosinor analysis can be used to estimate the characteristics of the circadian rhythm of Tc from data obtained on loggers that have limited memory capacity and battery life. The sampling interval can be manipulated to maximise the recording period, but the impact of sampling interval on the output of periodogram or cosinor analysis is unknown. Some basic guidelines are available from signal analysis theory, but those guidelines have never been tested on Tc data. We obtained data at 1‐, 5‐ or 10‐min intervals from nine avian or mammalian species, and re‐sampled those data to simulate logging at up to 240‐min intervals. The period of the rhythm was first analysed using the Lomb–Scargle periodogram, and the mesor, amplitude, acrophase and adjusted coefficient of determination (R2) from the original and the re‐sampled data were obtained using cosinor analysis. Sampling intervals longer than 60 min did not affect the average mesor, amplitude, acrophase or adjusted R2, but did impact the estimation of the period of the rhythm. In most species, the period was not detectable when intervals longer than 120 min were used. In all individual profiles, a 30‐min sampling interval modified the values of the mesor and amplitude by less than 0.1°C, and the adjusted R2 by less than 0.1. At a 30‐min interval, the acrophase was accurate to within 15 min for all species except mice. The adjusted R2 increased as sampling frequency decreased. In most cases, a 30‐min sampling interval provides a reliable estimate of the circadian Tc rhythm using periodogram and cosinor analysis. Our findings will help biologists to select sampling intervals to fit their research goals.

“…In general, the term "external stressor including environment" is broad and may include both biotic and abiotic stressors [5]. Out of all external environmental stressors, heat stress is the most detrimental stressor to different ruminants' species (such as cattle, buffalo, sheep, goats, and camels) [6][7][8].…”
