Eight Magra lambs (4–5 m of age and 13.41±0.74 kg BW) were randomly divided into two equal groups and offered complete feed for 120 days containing gram straw (Cicer arietinum) and concentrate mixture in 60:40 ratio in loose and densified form as complete feed block prepared at 4000 psi. Rumen parameters viz., pH, total volatile fatty acids, rumen ammonia nitrogen and total protozoal count were estimated at 0 (before feeding), 3 and 6 h post feeding. Haemato biochemical constituents were also analysed during 120 days of feeding at fortnightly intervals to adjudge the physiological status of the animals. There was no significant difference in pH, total volatile fatty acids and total protozoal count values among loose and densified form of complete feed fed groups. However, the time of sampling post feeding had significant effect on all the parameters. The rumen ammonia nitrogen concentration was significantly (P<0.01) higher in lambs fed complete feed in loose form than block fed group. Regarding haemato biochemical parameters of blood, all the parameters viz., haemoglobin, packed cell volume, blood glucose and total serum protein were well with in the normal range and there was no significant difference among the loose and block form of complete feed. It is concluded that densification of gram straw based complete feed had no adverse effect on rumen and haemato biochemical parameters in Magra lambs and complete feed blocks are as efficiently utilized as loose form of feed.
