Effects of Protein and Energy Restricted Diet During Lactation Leads to Persistent Morphological Changes on Tibia Growth in the Weaned Pups

The purpose of this study was to evaluate the effects of maternal protein and energy restriction during lactation on the body weight and tibiae dimensions of pups at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standar...

Growth and development Morphometry Rats Tibia Undernutrition The purpose of this study was to evaluate the effects of maternal protein and energy restriction during lactation on the body weight and tibiae dimensions of pups at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23% protein, 2) protein-energy restricted group (PR) - free access to an isoenergetic, protein-restricted diet containing 8% protein, and 3) energy-restricted group (ER) - fed restricted amounts of a standard laboratory diet.
