Summary

Study conducted to know the effect of sulphuric acid and urea treatment on voluntary intake and digestibility. The data obtained were analyzed using completely randomized design. Results showed that highest crude protein contents were recorded in case of urea treated (T3) but highest reduction in crude fiber, Ash and silica contents in case of Sulphuric acid treatment (T2). As cellulose and hemicelluloses contents were concerned T2 followed by T3 while there was no significant difference (P<0.05) in EE, lignin, NDF and ADF among treatments. Buffalo bull was used for determining the disappearance of dry matter by nylon bag technique for 24 and 48 hours incubation respectively. T2 highest dry matter digestibility as compared to T3 in case of 24 hours incubation, however no significant differences in T3 and untreated rice husk (T1) were observed but for 48 hours incubation there was no significant difference among treatments. Feeding trail was conducted for one month on twelve non lactating Nili Ravi buffalo randomly divided in three groups A, B and C (4 animal in each) with similar body condition score and weight. Three total mixed rations (TMR) based untreated (TMR-A), sulphuric acid (TMR-B) and urea treated (TMR-C) were prepared. The buffalo fed TMR-B showed (P<0.05) higher feed intake as compared to TMR-C and TMR-A. The apparent digestibility co-efficient for dry matter, crude protein, rude fiber and ether extract measured by total collection method and indicated that TMR-B was significantly (P<0.05) better digestible as compared to other rations. Key word: Rice husk, sulphuric acid, urea, in situ dry matter digestibility, TMR, feed intake, In vivo digestibility, buffaloes.
