Abstract

In this report we show that the amount of water lost during incubation is an important determinant of hatchability in embryos of the domestic chicken. However, when the loss of water is restricted to the first half versus the second half of the total incubation period, it is the loss of water during the first half that affects hatching success. We propose that regulating the permeability of the egg shell may be important in preventing excessive drying of the inner shell membrane during early development along with limiting the total amount of water lost from the embryo during incubation.

## Abstract Early in the history of the thalidomide disaster, chick embryos were β€œeliminated” as useful in the study of thalidomide. One reason for that conclusion was that many of the early experiments were flawed. We employed a number of experiments to expose chick embryos to thalidomide. Our dat

## Abstract Eight‐cell mouse embryos were frozen by using erythritol as the cryoprotective agent. The samples were cooled slowly (1Β°C/min) to temperatures between βˆ’ 15 and βˆ’ 75Β°C before direct transfer into liquid nitrogen (βˆ’ 196Β°C). The most effective concentration of erythritol for freezing of em
