Ambient Stress Associated Variations in Metabolic Responses of Marwari Goat of Arid Tracts in India

Abstract

Ambient stress associated variations in metabolic responses of Marwari breed of goat belonging to arid tracts in India were investigated by screening male and female goats of varying age groups during moderate, extreme hot and extreme cold ambiences. Metabolic responses were assessed by analyzing serum urea, creatinine, total proteins, cholesterol, triglycerides and glucose and the mean values were 5.67±0.05 mmol L-1, 120.98±1.44 umol L-1, 69.8±0.10 g L-1 , 3.3±0.03 mmol L-1 , 1.27±0.01 mmol L-1 and 3.63±0.03 mmol L-1, respectively during moderate ambience. The mean values of serum urea and creatinine were significantly (p≤0.05) higher during hot and cold ambiences, the mean value of total serum proteins and triglycerides were significantly (p≤0.05) lower during hot and cold ambiences and the mean values of cholesterol and glucose were significantly (p≤0.05) lower during hot ambience and significantly (p≤ 0.05) higher during cold ambience as compared to respective moderate mean value. Significant (p≤0.05) changes were observed in the value of each parameter according to sex and age. It was concluded that extreme hot and cold ambient temperatures affected the animals of both sexes and all age groups which was evident in the form of variations in the metabolic responses to combat the ambient stress.
