[Planned control of reproduction processes in industrialized sheep breeding].
Discussed in this paper are possibilities at present available for bio-engineering action to control reproduction  processes in ewes under the aspect of their applicability to industrialised lamb production. Reference, in this context, is make to the requirements of industrialised sheed breeding in establishing groups of young animals on the basis of cyclograms. Described is the most appropriate method at present to use feed pellets with megestrol acetate for oestrus synchronisation. The conclusion is that for the time being there is no method with sufficient economy by which to stimulate oestrus in sheep during the season and the non-oestral lactation period by which to bring forward the onset of sexual maturity.
