Abstract
|
|
|
Thirty female and sit male rats aged fourty days were divided into two groups in order to feed them by pairfeeding for 50g dietary restriction in the pair group two weeks interval. Each group contains 15 female and three male rats matched each rat between two groups in consideration of body weight.
Two female groups, one fed by 50% restricted diet and other Ad Libitum were divided into four groups each by the duration of dietary restriction during pregnancy;
First ten days dietary restriction at 50~~ level,
Last ten days dietary restriction at 500 level,
Dietary restriction at 50% level for full period,
And dietary unrestriction for full period
Urinary total nitrogen and creatinine´were determined.
The birth weights of offsprings were decreased partial and full period dietary restriction cf pregnant rats. There was no significant difference in the litter size of progeny due to the maternal diets. The growth was stunted in offsprings from the mothers fed restricted diet at 500.9 level for full period of pregnancy. No effect in the body weight gain of offsprings was observed in account of partial period of maternal dietary restriction. The urinary nitrogen of offsprings from eight dif-Lent groups did not show any statistically significant difference.
