Abstract: The objective of the present study was to assess the potential effects of solanine in potato by-products ( PB-P ) on minerals and vitamins utilization and nitrogen retaintion . Nine Rahmany rams at 3 years of age, 70.35 kg body weight devided into three groups three animals each their assigned to three digestion 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 results Indicated that the DMI of potato by - products silage ( PB-PS ) was higher than another tested treatments. Daily solanine dose is higher ( p<0.05) in potato by - products hay (PB-PH ) compared to PB-PS group. Some measures were taken on rations, blood, faeces and urine to determine the minerals and vitamins quantites . The results showed that the nitrogen intake was lower in BP-PH than control and BP-PS . Whereas nitrogen excretion was the highest in control and BP-PH groups than BP-PS group and the diffrences were significant ( p<0.05) . However. nitrogen balance was higher with BP-PS ration more than another expermintal groups. The minerals as well as calcium, phophorus, magnisium, sodium, iron, manganis, zink and potasium were significantly ( p<0.05 ) higher in PB-PS compared to PB-PH and control group, excepet for the potassium intake in was lower in PB-PS than other test groups, these results was almost similler to those obtained in blood serum. However, the mineral balance as well as, calcium, magnisium , sodium, iron, manganis , zink and potasium of PB-PS were significantly ( p < 0.05) higher than those of PB-PH and control diets. Whereas it was lower in phosphorus content copared to PB-PH group. The mineral intake as well as calcium, phophorus , magnisium, sodium, manganis, zZink and potasium were significantly ( p<0.05 ) lower in PB-PS than another groups, except of iron is higher in PB-PS than others. Whereas minerals balance of PB-PH were higher significantly (p < 0.05 ) in magnisium, zink and potasium than PB-PS , but it was lower in another elements. The results indicated that the vitamins intake as well as B1, B3 , B6 and C are significantly ( p < 0.05 ) lower in PB-PS ,except B2 is higher, than PB-PH and control groups. Serum blood of PB-PS were significantly ( p < 0.05 ) lower of all vitamins, except of vitamine B3 is higher. All vitamins serum blood of control group were significantly ( p < 0.05) higher than other groups.
