title: [Non-steroid Suisychron-Premix--its impact on reproduction of gilts in relation to the phase of the sexual cycle].
abstract: The action of Suisynchron-Prämix in its dependence on a given phase in the sexual cycle of gilts was studied with the view to improving effectiveness of its administration. A dose of gilts was studied with the view to improving effectiveness of its administration. A dose of 5 g/die was fed to the animals over 20 days, beginning with the third, eleventh, and 16th days of the cycle. The preparation was not fed to the controls. Brood sows in heat were selected and inseminated in compliance with the valid code of practice. Practice-oriented experiments then were conducted and elucidated the effect of Suisynchron upon the reproduction function of the sows concerned. The biologcial and economic effectiveness resulting from the use of Suisynchron, a nonsteroid preparation, was found to depend directly on the phase of the sexual cycle of swine, The regular course of sexual processes in swine is accompanied by characteristic changes, and sexual functions may be either intensified or weakened by administration of Suisynchron-Prämix.
