Abstract: A study was conducted on 20 lactating cows (in which 10 Crossbred and 10 Gir Cows) were divided into four groups on basis of nearest their body weight and milk yield/day at dairy farm (LPM) S.K.N. College of agriculture, Jobner (Rajasthan) and subjected to four dietary treatments were formulated. i.e. Green Lucerne (10 kg) + Wheat straw ad-lib.+ Concentrate (T₁-CB), Green Lucerne (20 kg) + Wheat straw ad-lib.+ Concentrate (T₂-CB), Green Lucerne (10 kg) + Wheat straw ad-lib.+ Concentrate (T₃-GC) and Green Lucerne (20 kg) + Wheat straw ad-lib.+ Concentrate (T₄-GC) and the studied for their behavioural pattern. Average maximum and minimum temperature (⁰C) was 25.60±0.245 and 15.64±0.285 in closed barn. DMI (kg/animal/day) was significantly (P<0.05) higher in T₂ (12.77) than T₁ (12.18)_, T₄ (11.49) and T₃ (11.07). Average eating time (minutes/day) was significantly (P<0.05) higher in T₂ (307.70) than T₁ (292.90), T₄ (272.40) and T₃ (266.60). Average resting time (minutes/day) was significantly (P<0.05) higher in T₃ (688.20) than T₄ (680.60), T₁ (660.40) and T₂ (653.50) during 24 hours.
