An exploration was conducted to appraise physiological strategies in Rathi female calves, heifers and cows from arid tracts implying alterations in serum 5’ nucleotidase (5’NT) activity during extreme ambiences. Break-up of the endeavour included sampling of animals during moderate, extreme hot, rainy and extreme cold ambiences in the arid tract of Bikaner district, Rajasthan, India. The cattle were classified into calves, heifers and cows. The overall mean value of serum 5’NT during moderate ambience was 58.00±0.40UL-1 ,which was obtained from 300 Rathi cattle incorporating calves, heifers and cows. The overall mean values of serum 5’NT were significantly (p≤0.05) higher during extreme hot, rainy and extreme cold ambiences in comparison to moderate mean overall value. During rainy ambience, the per cent variation in the value of serum 5’NT was found to be maximum (+56.89). It can be deduced that bang of rainy ambience was huge on overall serum 5’NT value followed by extreme hot and cold ambiences. Among physiological states, cows had higher overall value of serum 5’NT as compared to overall value of calves and overall value of heifers during moderate conditions. This pattern was maintained during all the three extreme ambiences with respective notable elevations during rainy ambience. Degree of influence of ambiences and physiological states on serum 5’NT was assessed by measuring per cent variations. Overall value revealed highest per cent variation during rainy ambience as compared to extreme hot and cold ambiences indicating that serum 5’NT was modulated maximally during rainy ambience followed by extreme hot and cold. Among calves, heifers and cows, per cent variations were highest in overall values of cows. This pattern was maintained in all the three extreme ambiences, extent being higher, respectively during rainy ambience. This precedent exhibited that calves were distressed largely and rainy ambience had greater impression on the animals. Archetype of per cent variation exhibited that among calves, pre-ruminant group revealed maximum modulations. Post-pubertal heifers were influenced largely in heifer group revealing maximum per cent variation during rainy ambience. Among cows, non-pregnant milch and primipararevealed superior effect as compared to other members of respective group. Rainy ambience revealed maximum temperature humidity index values. Extreme ambiences affected the liver functions of the animals
