Prasad T, Chhabra A, Atreja PP. Effect of feeding chelating agent (EDTA) on trace mineral balances in goats. Indian J Dairy Sci. 1994; 47(3):219-221. (CA) [Twelve adult male goats were fed on a diet contg. conc. mixt. (without mineral mixt.) and wheat straw as per NRC requirements. After a period of 200 days the goats were divided equally into three groups. The animals in group 1 were fed on a basal diet but the diet of the animals of groups 2 and 3 were superimposed with a chelating agent EDTA at 300 and 900 ppm, resp. After an adaptation of 21 days on EDTA supplementation, a mineral balance trial was conducted. Intake of DM was significantly increased in group 3 supplemented with 900 ppm EDTA. The Zn, Cu, Mn and Fe balances in groups 1, 2, and 3 were -6.34, -1.06 and -7.67; -2.64, -0.52 and -3.00; -7.30, +2.33 and -1.73 and -210.69, -337.03 and -405.93 mg/day resp. This suggested that EDTA supplementation at 300 ppm improved the Zn, Cu and Mn retention but not of Fe. This improvement in retention, however, disappeared at 900 ppm EDTA dose.
