Objective: To determine the effects of dietary supplements containing bovine serum concentrate (BSC, a source of immunoglobulins) and/or multiple micronutrients (MMN) on children's growth velocity, rates of common infections, and MN status.

Design: Randomized, controlled, community-based intervention trial.

Setting: Low-income, peri-urban Guatemalan community.

Subjects: Children aged 6-7 months initially.

Interventions: Children received one of four maize-based dietary supplements daily for 8 months, containing: (1) BSC, (2) whey protein concentrate (WPC, control group), (3) WPC MMN, or (4) BSC MMN.

Results: There were no significant differences in growth or rates of morbidity by treatment group. Children who received MMN had lower rates of anemia and (in the group that received WPC MMN) less of a decline in serum ferritin than those who did not, but there were no differences in other biochemical indicators of MN status by treatment group.

Conclusions: MMN supplementation reduced anemia and iron deficiency in this population, but the MMN content and source of protein in the supplements did not affect other indicators of MN status, growth or morbidity.

Sponsorship: Funding was provided by LG Laboratories (Ames, Iowa), which produces the bovine serum concentrate used in this study. The members of the research team have no financial involvement in this company.
