The effect of the liquid fertiliser on the embryogenesis of pheasants

Absztrakt

The human being pollutes the environment knowingly to improve in the quality for himself and for his
domestic animals and cultivated plants. Use of modern fertiliser and its technology was part and parcel of the
last one hundred years in the agricultural revolution. Quality problems of the environment constitute a violent
contest to the individual interests, that’s why the environment scientists have attacked that for years, to use
the fertilisers. The aim of this study was to answer for these disputed questions, studying the toxic effect of
liquid fertiliser on wild bird reproduction.
Birds were treated with blow-pipe per os, one part off eggs were injected through the air cap, another part
were treated in bath tub. The birds were examined according to the following view points: time of the
decease, production and fertility of the eggs. From eggs I conclude viability of embryos, malformations and I
measured the body weight. Finally I can conclude that to use the fertiliser is not a very toxic agricultural
method.
