Effect of proteinate or sulphate mineral sources on trace elements in blood and liver of piglets.

摘要: Four hundred piglets were housed in 20 pens and offered for 42 days a pre-starter then starter compound supplemented with trace elements given as sulphates (SULF) or proteinates (PROT) at common level (100) reduced (20) of inclusion. The supplied 278, 148, 315 98 mg/kg the 128, 38, 135 50 iron (Fe), copper (Cu), zinc (Zn) manganese (Mn), respectively, taking into account natural food contents. Proteinates used trial analysed described terms content quality different potential ligands. Piglet growth was not affected by any treatment. At end blood samples collected from eight pigs each These animals slaughtered their livers removed, weighed analysed. Compared SULF, PROT increased significantly plasma levels Fe (25·1 v. 15·7 μ mol/l), haemoglobin (10·9 10·4 g/dl) number red cells (6·4 6·1 millions per l) but liver recovery In receiving Cu Zn compared those SULF. On reducing dosage, decreased SULF amount more than PROT. results may reflect better availability when rather mineral supplements.
