| 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 . Howeve , 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 . | ||||
