| dc.description.abstract | ABSTRACT : In 4 x 4 LSD, four rumen fistulated graded Murrah buffalo bulls were fed four iso-nitrogenous complete rations with roughage to concentrate ratio of 60:40 and comprising of locally available crop residues viz., Jowar stover (T1), Maize stover (T2), Red gram straw (T3) and Black gram straw (T4) to study the effect on nutrient utilization, balances and rumen fermentation pattern. CNCPS fractionation indicated that carbohydrate fraction C was lower, protein fraction B3 was higher and protein fraction C was lower in Maize stover and Maize stover based complete ration suggesting that it is superior compared to other crop residues and crop residue based complete rations. The in vitro digestibility (%) of DM (P<0.01), CP (P<0.05), NDF (P<0.05) and ADF (P<0.01) were significantly higher in T2 compared to other dietary treatments while lower digestibility (%) was observed in red gram straw based complete ration. In sacco study revealed that EDDM (%) was higher (P<0.01) in T2 compared to T1 and T3, EDNDF (%) was higher (P<0.01) in T2 compared to T3 and T4 while EDADF (%) was higher (P<0.01) in T2 when compared to either T1, T3 or T4. However, EDCP (%) was comparable among all the treatments. The rumen fermentation studies with fistulated buffalo bulls revealed that rumen pH and TVFA concentration peaked 4 h post feeding while nitrogen fractions viz. NH3-N, Total – N, TCA insoluble N, residual nitrogen and food and protozoal N reached the peak 2 h post feeding. The digestibility (%) of DM, OM, CP, EE, CF, NDF, ADF, hemi-cellulose and cellulose were significantly higher (P<0.01) in T2 compared to other treatments while NFE digestibility was significantly higher (P<0.5) in T3 compare to T1 or T4. All the buffalo bulls were in positive nitrogen, calcium and phosphorus balance. The DMI expressed as kg/d or as % BW was similar among the different dietary treatments. The DCP and TDN content expressed as % in the diet consumed or kg/d was significantly higher (P<0.01) in Maize stover based complete ration (T2) compared to other crop residue based complete rations. The DE and ME intakes were higher (P<0.01) in T2 as compared to either T1, T3 or T4. The cost of complete rations containing different crop residues was 6.15, 6.09, 5.98 and 5.85 in T1, T2, T3 and T4, respectively. Based on the present study, it is concluded that locally available crop residues can be used in complete rations for graded Murrah buffalo bulls without any adverse effect. Further, it is concluded that Maize stover based complete ration is superior when compared to other crop residue based complete rations as evidenced by the better performance of animals. | en_US |
