Soyapulp (moisture 70–80%) contained OM 93.28, CP 30.06, EE 16.89, CF 7.75, NFE 38.58, NDF 60.58, ADF 16.53, liemicellulose 44.05 and cellulose 4.94% on DM basis. It could not be sundried alone due to its gel type texture and sticky nature. Mixture of fresh soyapulp with deoiled rice bran (DRB) in the proportion of 3:1 (T1), 4:1(T2), 5:1 (T3) and 6:1 (T4), and with wheat straw in the ratio of 4:1 (T5), 5:1 (T6), 6:1 (T7) and 7:1 (T8) were dried under the sun. T1 to T4 took 40 to 46h (DM 87.0 to 91.3%) whereas T5 to T took40 to 50 h (DM89.0 to92.7). Wheat straw and soyapulp mixed in the ratio of 1:3 to 1:6 could not be preserved after treating with urea (0.5%), common salt (1.5%) alone or in combination. Twelve crossbred calves (lyr., 153 kg) were divided into two groups and fed wheat straw ad lib (Group I) and wheat straw ad lib+Soyapulp ad lib (Group II) for 30d. Wheat straw DMI was 2.37±0.14, and 1.43±0.21 kg/d in group I, IT. Soyapulp DMI kg/d and per 100 kg B.wt. was 1.25±0.16 and 2.00 ±0.24 in group II. Digestibility coefficients of soyapulp calculated by subtraction method were; DM 65.61±6.61, CP 84.24±1.26, OM 64.91±10.40, EE 79.26±1.99, CF -48.63±34.62, NDF 61,93±9.98, ADF 21.24±18.82 and Cell contents 69.94±5.25. DCP and TDN contents of soyapulp were 25.33 and 80.87%, respectively.
