RESUMO

As autoras estudaram a composição corporal em proteína, água e gordura, em 2 grupos de ratas com restrição alimentar, que recebiam, respectivamente, 6g dia e 4g dia de uma dieta com 20% de proteína de caseína. Como percentagem de peso corporal houve aumento do teor de proteína e diminuição de água e de gordura nos grupos com restrição alimentar, em relação ao grupo controle. Na época do 19 estro a média ponderai não diferia, significativamente, nos 3 grupos.

ABSTRACT

At first estrus the feed-restricted rats were older and, proportionally to the age, leaner than the well fed animals. They had attained a greater proportion of protein and lesser proportion of water and fat; however the animals of the two restricted diet groups and the well fed group had the same weight.

First estrus was simultaneous with vaginal opening in 90% of the well fed animals, in 20% of the group I and in 0% of the group II.
