Abstract:
A study was carried out on sixteen lactating Gir cows were divided into four groups on basis of nearest their body weight and milk production at Dairy farm (LPM Deptt.) SKNCOA, Jobner (Rajasthan) and subjected to four dietary treatments were formulated. i.e. Wheat straw ad-lib.+ Green Lucerne (5 kg) + Concentrate (T₁), T₁ + Urea fed 75 g/cow (T₂), T₁ + Mustard oil cake fed 614 g/cow (T₃) and T₁ + Guar meal fed 505 g/cow (T₄) and the studied for their economics of milk production fed protein supplements of Gir cows during winter season. Average daily milk production (litre/cow) was significantly (P<0.05) higher in T₄ (7.85 litre) than T₃ (7.13 litre), T₂ (7.05 litre) and T₁ (6.67 litre). Total feed cost/litre of milk was Rs. 29.86, Rs. 24.19, Rs. 28.29 and Rs. 25.98 in T₁, T₂, T₃ and T₄ groups, respectively. T₄ (Guar meal) group as compared to other groups more economical and best performance. It was found that T₂ (Urea) group is economical but not better effect on milk yield of Gir cow. Total feed cost/litre of milk was Rs. 29.86, Rs. 24.19, Rs. 28.29 and Rs. 25.98 in T₁, T₂, T₃ and T₄ groups, respectively.
