Ambient Temperature Associated Variations In Serum Urea And Creatinine In Marwari Goats

Abstract

The present investigation was carried out on 540 apparently healthy Marwari goat of either sex, between 5 months to 4 years of age, to assess ambient temperature associated variations in serum metabolites of hepatic functions during moderate (October and November), hot (May and June) and cold (December and January) ambient temperature periods. In each ambient temperature period 180 blood samples were collected and the animals were grouped into male (90) and female (90). Further each group was divided according to age as 5-10 months (30 male and 30 female); 1-2 years (30 male and 30 female) and 2.5-4 years (30 male and 30 female). Serum metabolites of hepatic functions included in the study were urea and creatinine and the overall mean values were 5.62±0.20 mmol/l (3-14 mmol/l) and 94.97±2.90 µmol/l (55-153 µmol/l) respectively. The mean value of serum creatinine was significantly (p≤0.05) higher during hot and non significantly higher (p>0.05) during cold ambient temperature periods in comparison to overall moderate mean values, respectively. In each ambient temperature period the sex effect was significant (p≤0.05) for both metabolites serum urea and serum creatinine, the values were higher in male animals. In each ambient temperature period the age effect was significant (p≤0.05) for both the metabolites, serum urea and serum creatinine the values being highest in the animals of 2.5-4 years of age. The present study indicated that extreme ambience can stimulate the liver of the animals of both the sexes and all age groups, which was reflected in the form of increased activity metabolites in the serum.
