Abstract
The experiment compared the effect of feeding complete rations with conventional feeding system on rumen fermentation pattern of Murrah buffalo bulls. Four adult rumen fistulated buffalo bulls (5 y; 331±9.36 kg BW) were divided into four groups in a 4 x 4 Latin square switch over design and offered three isonitrogenous complete rations comprising of locally available crop residues viz. maize stover (T1), red gram straw (T2) and black gram straw (T3), and concentrate mixture in 60: 40 ratio, respectively, and a conventional ration (C) for a period of 28 days. The rumen-N fractions (NH3-N, TCA-insoluble nitrogen, Residual nitrogen), TVFA and pH were higher (P<0.01) in the SRL of animals fed rations T1 to T3 when compared to those animals fed C. The total N, food and protozoal N was similar among the treatment groups. It is therefore, concluded that feeding of complete rations comprising of locally available crop residues as roughage source provided conducive rumen environment for better nitrogen utilization and higher TVFA production than conventional ration.
