Abstract :

Twenty-eight Rahmani lambs were used in growth trial to examine effect of sprouted barley grain in sheep ration. Trials lasted to 90 days to investigate growth performance, digestion coefficients, rumen and blood parameters. Animals in control ration (G1) were fed clover hay (CH) plus concentrate feed mixture (CFM) (30 CH:70 CFM), where animals in in G2, G3 and G4 were fed 20%, 40% and 60% from dry matter intake green barley, respectively plus clover hay and CFM. Results indicated that G4 recorded higher significant digestibility of crude protein, ether extract, neutral detergent fiber and hemi-cellulose followed by G3, G2 and G1, respectively. Ruminal pH values were significantly higher with G1 compared with other groups at 4 hours and overall mean values. No significant differences were recorded in TVFA’s concentration among all groups in all sampling times. Groups fed rations contained green barley recorded higher values of average daily gain by 15%, 27% and 31% with G2, G3 and G4 respectively compared with control. Generally, there were positive effects on performance of growing lambs fed on sprouted grains.
