В статье представлены материалы научной работы, целью которой явилось изучение подвижности сперматозоидов нетрансгенных и трансгенных по гену рЛФ самцов-производителей поколения F4-5 с учётом кинематических параметров подвижности спермиев. Исследования показали, что все используемые в опыте козлы-производители характеризуются биологически полноценной спермой с быстроподвижными и прямолинейно-поступательно движущимися половыми гаметами с прогнозируемой высокой оплодотворяющей способностью. Показатели подвижности и кинематики спермиев, как у трансгенных, так и у обычных производителей, имели однотипный уровень значений, а значит присутствие чужеродного гена в организме трансгенных самцов поколения F4-5 не оказывает влияния на их репродуктивные функции. 

The article presents the materials of scientific work, the purpose of which was to study the sperm motility of non-transgenic and rLF gene transgenic males of F4-5 generation, taking into account the kinematic parameters of sperm motility. The studies showed that all the billy goats used in the experiment were characterized by biologically complete sperm with fast-moving and linearly progressive sex gametes with a predicted high fertilizing ability. Indicators of sperm motility and kinematics both in transgenic and in common billy goats had the same level of values, which means that the presence of a foreign gene in the organism of transgenic males of F4-5 generation does not affect their reproductive functions.
