Present study was conducted to analyse of the concentration of mono amino oxidase (MAO) in plasma along with bicarbonate in plasma and urine in non-descript goats of Rajasthan in response to the excess of free radicals. To execute the objectives, blood and urine samples were collected from the non-descript male (N= 60) and female goats (post-pubertal) (N=60) of 5 to 11 months of age (N=120) from private slaughter houses during the period of October to November i.e. moderate environmental temperature period (ETP) and the period of May to June i.e. extreme hot temperature period. In each environmental temperature period, males and females were classified as 5-7 months (N=20); 7-9 months (N=20) and 9-11 months (N=20) of age groups. The enzyme activity during extreme hot ETP was compared with those recorded during moderate ETP as control values. Mono amino oxidase levels showed a marked increase in extreme hot environmental temperature period. Bang of heat load was also noted during this extremely hot environmental temperature period. Under heat stress, plasma bicarbonate and urine bicarbonate levels were found to be raised as compared to control. MAO was also found to be higher in female goats as compared to male goats. Mono amino oxidase level was recorded highest in the youngest group (5-7 months old) as compared to other groups. A significant increase (p<0.05) in plasma bicarbonate level was observed in male animals as compared to female in both the ambiences. Significant (p<0.05) effect of age on plasma bicarbonate level was also observed, values being higher in older animals than younger age group in both the ambiences. It can be recommended from the study that water intake along with markers in plasma and urine should be watched carefully during the hostile environmental condition to avoid acid-base disturbances.
