Abstract
Domestic fowl embryonic oxygen consumption, organ growth and maturity, and growth abnormalities were studied after exposure to 2-, 1-, and 0.5-gauss (G) 60-Hz sinusoidal electromagnetic fields (EMF), throughout incubation. Embryonic growth and oxygen consumption increased after exposure to a 2-G EMF but they were inhibited by I-G EMF. There were no significant biological effects of 0.5-G EMF on embryonic growth and oxygen consumption. Deformities were found in the 2-G and 1-G EMF groups but only in the 2-G group did they reach a statistically significant level. There were no deformities in the 0.543 EMF group or any of the control groups. Pectoral muscles were most affected by an EMF of 2 G, while the intestine was largely spared the enhanced growth. The intestine was also spared the repression of growth at an EMF of 1 G; the lungs were most affected. Enhanced organ growth was associated with increased tissue maturity, particularly in pectoral muscles. The effects of a 1-G EMF on organ maturity were small but, paradoxically, lung maturity increased.
