Résumé partiel
The present investigation was carried out considering the hydration status vis-à-vis antioxidant level in non-descript sheep from arid tracts during extreme hot ambience or environmental temperature period. To investigate the hydration status vis-à-vis antioxidant level, blood samples and urine samples were collected from non-descript male and female sheep of 6 months to 12 months of age groups from private slaughter houses maintained under standard management conditions with the permission of Institutional Animal Ethics Committee (IAEC), College of Veterinary and Animal Science, Rajasthan University of Veterinary and Animal Sciences, Bikaner, Rajasthan. The male and female non-descript sheep were categorized as 6-8 months ; 8-10 months and 10-12 months of age groups in each environmental temperature period (ETP) or ambience. To accomplish the objectives, parameters were quantified in the plasma, urine and blood (where ever applicable) during moderate and extreme hot ETPs /ambiences. They included markers of hydration status (osmolality of plasma, tonicity of plasma, specific gravity of blood, viscosity of blood, osmolality of urine, specific gravity of urine, sodium, chloride and potassium in plasma and urine, magnesium, calcium and phosphorus in plasma and urine, total solids in urine, packed cell volume, erythrocyte sedimentation rate) ; acidification markers (plasma and urine bicarbonate ; fractional excretion of bicarbonate ; plasma anion gap ; urine anion gap ; pH of urine and colour of urine) ; associated analytes in plasma and urine (plasma urea, plasma creatinine, plasma glucose, urine urea and urine creatinine) and markers of antioxidant level in plasma (malondialdehyde, oxidase, vitamin A and vitamin C ).For each parameter, control mean value was obtained during moderate ETP/ ambience and the mean value obtained during extreme hot ETP was compared from control value of respective parameter. Per cent variation was also calculated for each parameter. Effect of sex and age was also considered. In the present investigation, hydration status and antioxidant level assessment was carried out on the basis of changes in parameters in nondescript sheep. Computation of the observations for each parameter revealed highly significant (p≤0.01) interactions i.e. environmental temperature period (ETP) X sex ; environmental temperature period (ETP) X age ; and sex X age. This revealed that extreme hot environmental temperature period affected hydration status and antioxidative level of male and female sheep of all the age groups
