Abstract: To observe the effects of partial replacement of soybean (de-oiled) meal with cottonseed expeller or decorticated solvent extracted cottonseed cake digestibility of nutrients, nutritive evaluation of the feeds. 18 Karan fries female calves of similar age (8-9 months) and body weight (114-115 kg) were randomly divided into three groups of each and allotted diets ‘C’, ‘T-1’ or ‘T-2’. The diet ‘C’ having 15% soybean meal, which was replaced by 10 parts with cottonseed cake expeller in ‘T-1’ diet or 10 parts by decorticated cottonseed cake solvent extracted in ‘T-2’ diet. An in vitro rumen degradability study of different diets was undertaken to determine the rumen degradability of DM, OM and CP. The in vitro rumen dry matter degradability (IVDMD_R) higher (P≤0.05) in ‘C’ (71.41±1.26) followed by ‘T-1’ (67.92±1.10) and ‘T-2’ (65.05±0.93) group. The IVOMD_R (%) was significantly higher (P≤0.05) in ‘C’ (67.03±0.85) and lowest in ‘T-2’ (55.03±0.91) group. IVCPD_R was significantly lower (P≤0.05) in ‘T-2’ (56.54±1.25) followed by ‘T-1’ (59.04±1.41) and ‘C’ (65.74±1.73).
