Unhatched eggs were broken to ascertain the percentage of embryonic mortality
No embryonic mortality
was detectable in the next 4 passages, although the same gross lesions were seen in the chicken embryos.
None of the samples from the three sites showed significant differences in embryonic mortality
or malformations, however, embryonic growth inhibition was observed at all three sites with more pronounced effects closer to the Monsanto plant suggesting that Monsanto plant contamination may contribute to the observed effects.
The poisons led to failure to lay eggs, thinner egg shells and breakage, and increased embryonic mortality
Nor is sex-selective early embryonic mortality
a mechanism by which the observed male bias is brought about (20).
