[Study of the fertility of bull sperm contaminated with Aspergillus fumigatus spores].
Tested was the penetrating capacity of 55 samples of bulls' semen, contaminated with Aspergillus fumigatus, so far as the estrous secretion of cows was concerned. A total of ten cows in heat were inseminated with spermatozoa carrying the Aspergillus spore infection. It was found that the contaminated semen was with deteriorated quality and a 50 per cent lowered penetrating capacity as against the controls. The inseminated cows conceived with difficulty, exhibited disturbances in their sexual cycle, and two of the animals showed data of early embryonal death.
