Adult sheep (2) were equally divided into 4 groups and fed sole gram straw as control (C), gram straw+raw bajra grain (T1), gram straw+reconstituted bajra grain (T2), gram straw+4; urea treated bajra grain (T3). The total dry matter intake was significantly lower in the group fed solely gram straw in comparison to other groups. Crude protein (CP) was higher in T3 than in T1 and T2 and was minimum in treatment C. The digestibility coefficients of all the proximate nutrients were calculated by difference and were significantly higher in reconstituted and urea treated than that in raw bajra grain. The DCP in raw bajra grain (6.23;) was lower than that in reconstituted (8.74;) and in urea treated (13.84;); the differences between reconstituted and urea treated grain being significant. Similarly, the TDN content was higher in reconstituted (70.73;) and in urea treated (70.57;) than in raw (57.25;) bajra grain. Mean nitrogen fractions in SRL of sheep were significantly (P0.01) higher in T3 than that in T1 and aT2, while the fractions peaked at 2 h post - feeding. Lower pH and higher TVFA values were recorded at 4 h as compared to 0,2 and 6 h post feeding. The NH3-N and urea - N in serum of sheep pre-feeding (0 h) were similar in T1,T2 and T3, but at 3 h post feeding the value in T3 was considerably (P0.01) higher than the values in T1 and T2.
