The development of recombinant somatotropic hormone (STH) creates a prerequisite for a wide application of exogenous stimulation of meat and milk performance of cows and pigs. Reproduction effect and its mechanism is till now restricted by a lack of complex information through there are several studies of principal character and basic effects of STH on reproduction process are also known. The result of some experimental studies, quoted in scientific literature, was a hypothesis that STH effect is accompanied by increased production of so-called insulin-like growth factors. Moreover, it is known that these factors have a steroidogenic effect. A hypothesis of STH action, just by means of insulin-like growth factors, was expressed on the basis of the above mentioned fact. Our study was aimed at the analysis of the effect of recombinant porcine somatotropic hormone (rpSTH, Research and Development, Pittman-Moore, Inc.
