The experiment concerning the effect of diet containing different level of phytate and lead (Pb) in drinking water on blood mineral and growth of local starting duck 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. In this experiment, study of the effect of diet containing different level of phytate and lead in drinking water on calcium, zinc and iron of blood; feed consumption, body weight gain, and feed conversion ratio of starting duck were conducted. The experimental design used a completely randomized design with a factorial pattern 3x3. Three dietary treatments containing different levels of phytate (0,15; 1,17 and 2,16%) and 3 levels of lead in drinking water (0, 45 and 90 ppm) with 3 replication were applied. The results showed that there was an interaction of phytate in diet and lead in drinking water on feed consumption. The main effect of lead treatment up to 90 ppm increased calcium, zinc and iron of blood. Concentration of lead up to 90 ppm in drinking water did not affect feed consumption, body weight gain and feed conversion ratio. The main effect of phytate up to 2,16% in diet increased feed consumption, body weight gain and feed conversion ratio.
