[Vitamin B1 nutritional status of the lactating XXXX and her litter as a function of the dietary level of thiamine].

Influence of the Dietary level of @entity15854 on the @entity71585 utritional Status of the Lactating @entity35 and the litter. Seven Groups of female @entity35 which had given birth to the litters of 8 youngs (or litters adjusted to 8 youngs) were fed diets containing respectively 0.5, 1, 2, 4, 8, 16 or 32 mg/kg of @entity15854 . Eighteen days after littering, the @entity15854 content was measured in female tissues (blood, liver, carcass) or in those of the youngs (liver, carcass). Besides, the @entity15854 content in the stomach of the youngs was measured, 3, 7 and 14 days after birth. 1. In the females there are linear or cubic relationships between the @entity15854 content in the tissues and the log-concentration of the vitamin in the diet. In the liver and the carcass, it seems that the vitamin level in the tissues reaches a plateau when the dietary level is below 1 mg/kg or above 16 mg/kg. 2. On day 7th or 14th the gastric vitamin content (milk) in the youngs gradually increases, as the dietary @entity2221 supply does, and especially on day 14th when the dietary level of @entity15854 is 2 mg/kg or higher. 3. In the youngs, the organ @entity15854 contents markedly increase when the dietary supply rises from 1 to 8 mg/kg. Below 1 mg/kg and beyond 8 mg/kg there is a plateau. 4. These results suggest that the @entity15854 fixation in the offspring tissues occurs prior to the fixation in the lactating mother. The priority would be proved by the fast increase of the milk content in @entity15854 during the 2nd week when the vitamin dietary supply rises.
