    The nature of embryomortality in hatcheries and the posiible causes for embrypathies were studied. Experimental studies were conducted by inoculating Oxytetracycline, Ochratoxin A, Citrinin and a combination of ochratoxin A and Citrinin and avian influenza virus. Ultrastructural studies were conducted to elucidate the subcellular changes in the liver and kidneys of the embryo after administration of the mycotoxins. The various abnormalities noticed were early embryonic death, curled embryos, dead in shell, live sticky embryos, oedema of head and neck emphalitis and septicaemia, gastroachisis with herination of yolk sac, coelosoma, dwarfs, curled toe, microphthalmia, anopthalmia, brachycephaly, parrot beak, crossed beak, brachygnatha, streptosomia and a few cases of diprosopus, polymelia
