Two rumen fistulated adult male buffaloes were fed individually on three different diets namely wheat and bajra straw based complete feed blocks and conventional diet comprising concentrate mixture, green fodder and wheat straw. The same concentrate mixture was used to make complete feed blocks based on wheat straw (WSCFB) and bajra straw (BSCFB) having wheat/bajra straw: concentrate in the ratio of 60:40 on fresh basis. Buffaloes in these treatment groups were also offered green fodder as in control group. CP content of concentrate mixture was 18.82; whereas WSCFB and BSCFB contained 8.96 and 9.04;, respectively. The TVFAs concentration increased from conventional diet to the complete feed block diets with a peak concentration at 4 h post feeding. Similarly, pH values were affected by the diets as well as time of sampling. pH values decreased from conventional diet to the complete feed block diets. Total-N and TCA-N concentrations in SRL on complete feed diets were higher than on conventional diet, however, mean NH3-N concentration in SRL was higher (P0.05) in control group than in WSCFB group. It was concluded that feeding of complete feed blocks based on wheat or bajra straw as sources of roughage at 60; level has a comparable effect on N utilization, TVFAs production and ruminal pH.
