Environmental conditions versus cellular metabolic regulators of kreb cycle in Sirohi goat from Southern Rajasthan

Hot environmental conditions can put immense stress to animals touching health and production. Therefore, a study was embarked on Sirohi goat from un-organized sector from Semi-arid tracts of southern Rajasthan to assess the effect of moderate, humid-hot, dry-hot and cold environmental conditions. Bang of environment on animals was assessed by determining heat load index and the values obtained were 67.82, 81.70, 83.80 and 54.80, respectively during the moderate, dry-hot, humid-hot and cold environmental conditions. Serum isocitrate dehydrogenase (ICDH) and malate dehydrogenase (MDH) were determined by the standard protocol as representatives of cellular metabolic regulators. Serum enzymatic activities divulged remarkable changes during dry-hot and humid-hot environmental conditions. Maximum activity of serum ICDH was noted during cold EP. During cold, the per cent variation in the value of serum ICDH was found to be maximum (+21.69), While during humid-hot, the per cent variation in the value of serum MDH was found to be maximum (+75.25). The model of changes expounded the lilt of cellular activities in animals of different age groups during dry-hot and humid-hot ambiences. The snarl of the effects was higher during humid-hot than dry-hot. Animals of female group and older age group were observed to be more affected.

• Humid-hot and dry-hot generated more stress and oxidative stress than moderate environmental period in the Sirohi goat.

• Female goats and old aged goats were affected more than male goats and young stock, respectively.
