| Abstract | ||||
| The current work was carried out to investigate the effect of dietary minerals intake and minerals status in animal body on minerals concentration in saliva and urine of buffaloes. Twelve dairy buffaloes and 12 growing heifers almost similar in age and live body weight were fed traditional summer' and winter rations. Also, two metabolism trails were conducted using barki rams to determine minerals balance of these rations. Samples of saliva, urine and feedstuffs were taken two times through the experimental period after three months of feeding traditional summer and winter rations for minerals determination. The contents and intake of P, Mg, Na and In were higher, but the contents and intake of Ca, K, Cu, Mn and Fe were lower significantly (P<0.05) for summer ration compared with winter ration. Moreover, the concentrations of P, Na, K and In in saliva and the concentrations of Mg, Na and K in urine increased significantly (P<0.05) with increasing the intake of these elements. However, the concentrations of Ca, Mg, Cu, Mn and Fe in saliva and the concentrations of Ca, P, Cu, In, Mn and Fe in urine were not significantly (P> 0.05) affected by the intake of these elements. The concentrations Ca, Mg and Mn were higher and the concentrations of P, Na, K and Cu were lower significantly (P<0.05) in saliva of dairy buffaloes compared with their growing heifers. While, the concentrations of In and Fe were not differing significantly (P>0.05). Moreover, the concentrations of Ca, P, Mg, Cu, In, Mn and Fe were higher significantly (P<0.05) in urine of growing heifers in comparison with dairy buffaloes. While, the concentrations of Na and K were nearly similar. | ||||
