The Effects of Tetracycline on Chick Embryos

This embryo was smaller and weighed significantly less than the other
experimental embryos (16.9g). In addition, the external organs were exposed, there was no feather growth and the embryo died during the experimental period.
Our experiment found that three embryos did not fertilize (embryos 1, 10, and 12) and were not part of the conclusions.
In conclusion, our experimental findings showed that tetracycline is inhibitive to normal embryo growth as found in embryos two through six. Further, higher dosages of tetracycline are detrimental to embryonic growth as noted in embryos seven.
If future testing is done, more embryos should be injected at the higher 0.2mg dosage to validate the findings from embryo seven and an internal study of embryos two through six (with 0.05mg tetracycline) should be conducted to determine possible contributing factors to the abnormally large growth of these embryos.
