Introduction
In
acutely facing the problem of remote consequences of influence on an organism
of chemical substances, impact on reproductive function is important. In recent
years, in farms and private farms specializing in the cultivation of cattle and
small cattle, as well as rabbits, there are violations of reproductive
function, manifested in infertility and spontaneous abortions, pre - and
postimplantation developmental delay, physiological and behavioral changes in
the offspring, malformations and transplacental effects, and often their
etiology remains unclear. Our long-term production and experimental studies
allow us to conclude that one of the leading factors in the development of
these violations is the unfavorable environmental situation in many regions of
Uzbekistan as a result of various anthropogenic influences, including: the
significant use of chemicals to protect plants and animals from pests and
diseases, as well as other toxic substances. Currently, the most widespread as
a means of protection of plants and animals from various pests have synthetic
pyrethroids (cypermethrin, esfenvalerate, karate) and organophosphorus
pesticides (basudin, aktellik, etapas, location) [1-3].
