Abstract :
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.
