Effect of Formaldehyde Treated Concentrate, Urea and Soybean Meal on Feed Conversion Efficiency and Economics of Milk Production in Cows

Present investigation entitled “effect of formaldehyde treated concentrate, urea and soybean meal on feed conversion and economics of milk production in cows.” was undertaken at Department of Animal Husbandry and Dairy Science, Dr. Panjabrao Deshmukh Krishi Vidyapeet, Akola. Feeding of 1.5 per cent formaldehyde treated 70:30 sugras : SBM concentrate mixture with 2 per cent added urea diet to lactating cows (T₃) was evaluated in relation to sugras untreated ration (T1). It was noticed that DCPI/kg milk yield was influenced by the feeding treatments being less by 7.23 and 10.84 per cent. The average DMI and TDNI intakes were 1.37 and 0.867, 1.77 and 0.851, 1.17 and 0.778, 1.23 and 0.810 and 1.17 and 0.772 kg/kg milk yield under T₁, T₂, T₃, T₄ and T₅ groups, respectively, as a result the corresponding feed conversion efficiency emerged out as 73.14, 78.79, 83.73, 81.10 and 85.20 per cent, respectively, gross protein efficiency (GPE) was found comparatively more by approximately 7.33 to 7.92 per cent in T₃ and T₅ cows as compared to T₁, T₂ and T₄ group cows, the values being 41.33, 40.74, 48.66, 42.98 and 48.36 per cent in T₁, T₂, T₃, T₄ and T₅ groups, respectively. Moreover, similar trend was noticed in respect of net protein efficiency (NPE) under different treatments. The NPE values were 67.99, 62.66, 76.68, 66.26 and 76.94 per cent under T₁, T₂, T₃, T₄ and T₅ groups, respectively. On an average daily feeding cost worked out as Rs.49, 50, 52, 42 and 43/cow in T₁, T₂, T₃, T₄ and T₅ groups, respectively.
