Abstract EN
Some metabolic alterations were evaluated in Wistar rats which received control or low-protein (17%; 6%) diets, from the pregnancy until the end of lactation: control non-lactating (CNL), lactating (CL), low-protein non-lactating (LPNL) and lactating (LPL) groups.
Despite the increased food intake by LPL dams, both LP groups reduced protein intake and final body mass was lower in LPL.
Higher serum glucose occurred in both LP groups.
Lactation induced lower insulin and glucagon levels, but these were reduced by LP diet.
Prolactin levels rose in lactating, but were impaired in LPL, followed by losses of mammary gland (MAG) mass and, a fall in serum leptin in lactating dams.
Lipid content also reduced in MAG and gonadal white adipose tissue of lactating and, in LPL, contributed to a decreased daily milk production, and consequent impairment of body mass gain by LPL pups.
Liver mass, lipid content and ATP-citrate enzyme activity were increased by lactation, but malic enzyme and lipid: glycogen ratio elevated only in LPL.
Conclusion.
LP diet reduced the development of MAG and prolactin secretion which compromised milk production and pups growth.
Moreover, this diet enhanced the store of lipid to glycogen ratio and suggests a higher risk of fatty liver development.
