The effects of diet on mineral concentrations in serum, liver and endometrium were determined at points in the reproductive cycle in heifers. Dietary treatments extended 134 d and included feeding a basal hay (negative control), basal hay with concentrate (feed control), feed control with phosphorus and feed control with both phosphorus and trace minerals. Samples of serum and liver were taken at the beginning and end of the trial. Within an estrous cycle during the trial (endometrial biopsy) the cows were sampled either at Day 1 or Day 12 for determining progesterone levels and mineral elements in the blood, liver and endometrial tissue. Trace element concentrations in serum and liver did not differ among collection periods pretrial, endometrial biopsy and post breeding nor among treatment groups. However, endometrial tissue concentrations of copper, manganese and zinc were higher at Day 1 than at Day 12 (P < 0.05) in reverse of serum progesterone, which was higher at Day 12 (P < 0.05). Supplemental trace minerals appeared to increase concentrations of copper (P < 0.20), manganese (P < 0.10) and zinc (P < 0.20) at Day 1 but decrease concentrations of these same elements at Day 12 (P < 0.05, P < 0.10 and P < 0.05, respectively). The large differences in trace element concentrations observed in endometrial tissue at the estral phases and under different diets suggest the possible importance of trace elements and trace element nutrition in fertilization and (or) embryo survival.
