The present study was undertaken to evaluate the effect of microclimate alteration devices and feed additives on productive performance and feed intake of lactating Murrah buffaloes during summer for a period of 90 days. Twenty four early lactating Murrah buffaloes of similar body weight, parity and milk yield were selected and distributed randomly into 4 equal groups by using randomized block design (RBD). The first group T1 was provided with foggers operated daily during hot hours from 12.00 Noon to 15.00 PM, T2 with fans, T3 with fans and feed additive containing Chromisac (Chromium plus yeast) @ 500 g/ton of feed and control group without any cooling device and feed additive. The average daily dry matter intake (DMI) in T1 (15.37 ± 0.08 kg) was found to be significantly higher thanT2 (14.25 ± 0.15), T3 (14.65 ± 0.06) and control group (13.99 ± 0.11 kg).The average daily milk yield was significantly higher in T1 (10.94 ± 0.33) compared to T2, T3 and control groups, 9.55 ± 0.63, 9.78 ± 0.30 and 9.16 ± 0.36 kg, respectively. The milk constituents fat, SNF and Total solids did not differ significantly among the groups. The average daily 6% FCM yield of various experimental was found to be 12.58 ± 0.34, 10.89 ± 0.73, 11.33 ± 0.29 and 10.44 ± 0.40 percent for T1, T2, T3 and control, respectively. The use of foggers as microclimate alteration device was more advantageous over the other air circulating devices and with feed additive supplementation.
