Abstract
The purpose of the experimental study was to clarify whether the dietary protein levels would be related to the β-BHC deposition in dam and offspring of rats during gestation and lactation. The results obtained were as follows:
1) It was recognized that the increase of the dietary level of protein lowered the deposition of β-BHC in dams, especially in liver, during gestation period. However, no marked difference in fetuses was noticed.
2) As to the difference between pregnant and normal rats, in low protein diet, the β-BHC deposition of the former was higher about two times than that of the latter.
3) By the administration of 14C-labelled β-BHC to pregnant rats, it became clear that the stage of this administration during the gestation influenced the distribution of the radioactivity, especially in liver and kidney of dams.
4) Change in the amount of β-BHC deposited in the dams after 10 day's lactation was much remarkable between 5 and 10% casein diets.
5) β-BHC transfered from dam to offspring of rats during lactation was higher about ten times than that of the period of gestation.
