Abstract:
The present study was carried out on twenty four lactating Murrah buffaloes housed in four different groups (six in each group) viz. foggers (T1), fans (T2), fans and feed additive (T3) and control group (C) in LRS, Mamnoor. The stress hormones estimated by the influence of microclimatic alteration devices and feed additive on Murrah buffalaoes were Triidothyronine (T3), Thyroxin (T4) and Cortisol. The serum total T3 levels were higher in C group followed by T3, T2 and T1 groups while total T4 levels were higher in C group followed by T2, T1 and T3 groups. The serum cortisol levels were higher in C group followed by T2, T3 and least in T1 group of Murrah buffaloes.
