Abstract: This study was conducted to investigate the effect of solanine in potato by products as silage or hay on microorganisms activities and some another parameters in Rahmany rams. Nine adult rams with an average body weight of 70.35 kg and 3 years of age were randomly divided into three groups, assigned to three digestior trials with three experimental rations. The experimental diets were consists of 50 % concentrate feed mixture (CFM) + 50% roughage as well as berseem hay in control ration, potato by-products silage (PB-PS) and potato by-products hay (PB-PH) in second and third rations, respectively. The digestion trials was lasted for 4 weeks .The obtained results showed that PB-PS diet was significantly lower ( p<0.05 ) in crude fiber, and higher in crude protein (CP) and ether extract ( EE ) Cgared to the another treatments. On the other hand the higher values of crude ber and solanine were found in PB-PH diet value of NDF, ADF, ADL , cellulose and hemicelluloses were significantly ( p < 0.05 ) decreased in PB-PS , whereas this values were increased in PB-PH and control diet .The higher values of acetate, Butrtate, Iso - Butrate were- detected in PB-PH , whereas the PB-PS diet recorded higher value of propionate and valerate, and lower value of A : p ratio compaered to control treatment. Both of ammonia -N and VFAs in rumen liquor were higher significant (p< 0.05 ) in silage group followed by PB-PH and control group through different times .The total bacterial count and cellulebacterial and protozoal were significantly higher ( p < 0.05 ) . in PB-PS at 0, 3 and 6 hrs after feeding. On the other hand PB-PH was lower in RBC and Monocyte while it was higher in PB-PS and control groups. Neutrophile. WBC, Eiosinophile , Lymphocyte. were significantly higher ( p < 0.05 ) for PB-PH compared with PB-PS and control groups.
Keywords: Solanine, Potato by-products, microorganisms activities, another rumen parameters.
