Egg Fertility

This study deals with the effects of administering 15 ppm of p,p′-DDT in the diet of Japanese quail (Coturnix coturnix) over three generations. Four parameters were measured: (1) egg production, (2) egg fertility, (3) number of abnormal eggs produced, and (4) egg residue concentrations. A comparison of first- and third-generation data shows that egg production decreased slightly, fertility and percentage fertility decreased substantially, the production of abnormal eggs increased, and residue concentrations in the eggs increased. The study suggests that the duration of exposure may be as important as the concentration of DDT administered.

Quantitative Ultrastructure

It is anticipated that Japanese quail /Coturnix coturnix japonica/ will provide animal proteins in long term space flights. Consequently this species of birds is of research interest of international space program INTERCOSMOS. In the year 1987 we reported on an experiment /2/ in which the effect of chronic acceleration of 2 G hypergravitation, the hypodynamy and the simultaneous effect of chronic acceleration and the location in the centre of the turntable of the centrifuge on the protein fractions in skeletal muscles was studied. The ultrastructure of the heart muscle was now in this experiments examined as well.Japanese quail cockerels, aged 48 days were exposed to 2 G hypergravitation /group IV/ in a 6,4 m diameter centrifuge, to hypodynamy /group III/ and their combination /group V/, respectively for 6 days / Fig.1/. The hypodynamy in group III was achieved by suspending the birds in jackets without contact the floor. The group II was located in the centre ofthe turntable of the centrifuge. The control group I. was kept under normal conditions. The quantitative ultrastructure of myocard was evaluated by the methods of Weibel/3/ - this enables to determine the number, relative size and volume of mitochondria volume of single mitochondria, defficiency of mitochondrial cristae and volume of myofibrils.
