Effects of Ferrous N-Carbamylglycinate Chelate on Growth Performance, Serum Iron and Antioxidant Indices of Piglets
摘要
Abstract
The aim of the present study was to investigate the effects of ferrous N⁃carbamylglycinate chelate ( Fe⁃CGly) on growth performance, serum iron and antioxidant indices of piglets. Eighty piglets ( Duroc × Landrace×Large Yorkshire) at 40 days of age were randomly assigned to 2 groups with 4 replicates per group and 10 piglets per replicate. The diets of control group and experimental group all contained 180 mg/kg iron, the diet of control group only supplemented with Fe2SO4·7H2O, and the diet of experimental group only sup⁃plemented with Fe⁃CGly. The experiment lasted for 21 days. The results showed as follows:compared with the control group, the average daily gain (ADG) of experimental group was increased by 10.37% (P>0.05), while the ratio of feed to gain was decreased by 5.59% (P<0.05). The serum iron content of experimental group was significantly higher than those of control group ( P<0.05) , the serum ferritin and hemoglobin con⁃tents of experimental group were higher than that of control group ( P>0.05) . The serum superoxide dismutase ( SOD) activity of experimental group was significantly higher than that of control group ( P<0.05) , while the malonaldehyde ( MDA) content of experimental group was significantly lower than that of control group ( P<0.05). Thus, it can be concluded that the Fe⁃CGly has benefits on improving growth performance, iron metab⁃olism and antioxidant status in piglets.关键词
