• Resumen

  • A trial was carried out in order to determine the effect of different mineral sources on the concentration of Ca (CSCa), P (CSP) & Mg (CSMg) in blood serum and Ca (CHCa), P (CHP) and Mg (CHMg) in bone ribs of crossbred lambs. The treatments evaluated during 105 d, were: T0: hay ad libitum + 135 g of supplement (corn gluten meal: 80.4 %, soybean meal: 17.6 % & urea: 2 %); T1: hay ad libitum + 125 g of supplement (poultry litter: 80 % & molasses cane: 20 %), T2: T0 + 5 g of dicalcium phosphate and T3: T0 + 7 g of commercial mineral mixture. Twenty lambs (5 lambs/treatment) of 11 kg liveweight and 4 months of age were used in a randomized design. The concentration of minerals in blood serum for T0, T1, T2 & T3 were: CSCa (P
