Resumos

As autoras estudaram em dois grupos de ratas com restrição alimentar, que recebiam, respectivamente, 6g dia e 4g dia de uma dieta com 20% de proteína da caseína, a idade e o peso dos animais na abertura da vagina e no 19 estro. A média de peso dos animais nos 2 grupos não diferiram, significativamente, da do grupo controle, embora os primeiros apresentassem maturação sexual mais tardiamente que o último.

Age and weight were determined by direct measure in 30 feed-restricted female rats studied from weaning to first estrus, and compared to well fed controls. At the first estrus the average weight of well fed rats did not differ from that of the feed-restricted groups.

Mean ages at vaginal opening and first estrus in the feed-restricted animals were however greater.
