Effects of soy beverage and soy‐based formula on growth, weight, and fecal moisture: experimental study in rats

Abstract

Objective: To compare body growth, weight, and fecal moisture in recently weaned rats fed exclusively on infant soy formula and soy protein-based beverage. Methods: Three similar groups were formed (n = 10/group) consisting of weanling Wistar rats, maintained in metabolic cages. One group was fed soy protein-based beverage, another with soy-based infant formula, and another with cow's milk infant formula (control group). Water and diet were offered ad libitum. Body weight and length were measured. Stool was collected for three consecutive days. Results: Weight and length were lower (p = 0.001; p = 0.001) in the groups receiving soy protein--based beverage (73.16 g ± 5.74; 23.94 ± 1.04 cm) and soy-based formula (71.11 ± 5.84 g; 24.74 ± 0.60 cm) in relation to the group receiving cow's milk formula (84.88 ± 9.75 g; DOI se refere ao artigo: http://dx.doi.org/10.1016/j.jped.2014.09.003 ଝ Como citar este artigo: Silva MdL, Speridião PdG, Marciano R, Amâncio OM, Morais TB, Morais MB.
