The present investigation was conducted Comparative Study on Nutrient Utilization of Cross-Bred and Gir Cows Feed Green Lucerne During Winter Season. Twenty lactating cows (in which 10 Cross-bred and 10 Gir Cows) were divided into four groups on basis of nearest their body weight and milk yield/day at dairy farm of S.K.N. College of Agriculture, Jobner and subjected to four dietary treatments were formulated. i.e. Green Lucerne 10 kg + Wheat straw ad-lib.+ Concentrate for T1 Crossbred, Green Lucerne 20 kg + Wheat straw ad-lib. + Concentrate for T2 Crossbred, Green Lucerne 10 kg + Wheat straw ad-lib. + Concentrate for T3 Gir Cow and Green Lucerne 20 kg + Wheat straw ad-lib. + Concentrate for T4 Gir Cow and the studied for their nutrient utilization. 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 daily intake of CP, DCP and TDN in kg/100 kg body weight was significantly higher (P<0.05) in T2 compared to other groups. The nutrient utilization as DM, CP, EE, CF and NFE was significantly (P<0.05) higher in T4 compared to T3, T2 and T1 group.

Highlights

• DMI (kg/animal/day) was significantly higher in T2 (12.77) than T1 (12.18) Cross breed and T4 (11.49) than T3 (11.07) in Gir Cow.
• The nutrient utilization as DM, CP, EE, CF and NFE was significantly (P<0.05) higher in T4 compared to T3, T2 and T1 group.
