EFFECT OF Pb-ACETATE IN DRINKING WATER AND PHYTATE IN DIET ON CALCIUM, ZINC AND IRON IN BLOOD OF GROWING DUCK

The research was conducted at the Laboratory of Physiology and Biochemistry, Faculty of Animal Husbandry and the Laboratory of Chemistry Material and Environment, Faculty of Mathematics and Natural Science, Padjadjaran University. Treatment of Pb-acetate in drinking water was given during 16 weeks. The purpose of this study was to determine the effect of Pb-acetate in drinking water and phytate in diet on concentrations of calcium, zinc and iron in blood of growing duck. The experimental design used a completely randomized design (CRD) with a factorial pattern 3x3. Three levels of Pb-acetate in drinking water (0, 45 and 90 ppm) and dietary treatments containing different levels of phytate (0,12; 1,16 and 2,18%) with 3 replications were implemented. The results showed that there was no interaction between lead in drinking water and phytate in diet on calcium, zinc and iron of blood. The main effect of lead treatment up to 90 ppm increased calcium, zinc and iron in blood, but the main effect of phytate up to 2,18% in diet did not give significant difference.
