Prevention of Negative Impact of Pesticides and Other Toxic Substances on Reproductive Function of Animals

 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].

 

The use of these drugs helps to increase the yield of food and industrial crops, reduce production costs, protects productive animals from ecto - and endoparasites – carriers of various infections and invasions. However, their irrational use often causes environmental pollution (soil, water sources, feed) and causes poisoning, other negative consequences and, in particular, violations of the reproductive function of animals. Among other toxic substances that adversely affect the reproductive function of animals, gossypol cotton feed deserves some attention.
