ABSTRACT

Changes in sheep production during the recent one-hundred years were not so drastic as was the case in the last 50 years. The almost exclusively wool-producing species was replaced by a dual, and in some cases threefold purpose animal, due to the demands for mutton and sheep milk. Sudden expansion of demand for mutton and profitable opportunities for exportation in the early 1970s triggered the need for elaboration of biological procedures by means of which an intense increase of the lamb crop could be achieved in order to enhance meat output, both in large and small scale operations.
Increased lambing frequency provided a quick and relatively effective method. This was theoretically possible due to the favourable characteristics of the species. The result, however, could not always be calculated. The incalculable seasonality of the reproduction biology of sheep was hidden in the background of the failure.
Induction of heat and oestrus synchronization proved to be a good procedure in producing lamb crops out of season. Due to the favourable experiences, it can be applied under the changing conditions at present, as well.
Increase of lamb crops and/or effective and quick improvement of the breeding level can hardly be anticipated without reorganization and wide-spread application of artificial insemination. Taking into account the present hopeless situation of the sheep production sector, effective and quick intervention, as well as subsidies by the agricultural government and that of the agricultural societies would be needed for progress.
Inclusion of active previous experts who contributed to the elaboration of the methods, and seemed to be successful at that time, can hardly be avoided.
The use of well proven procedures during the recent 20-30 years, such as induction and synchronization of oestrus as well as artificial insemination, may be effective tools in the reorganization process of animal production, since at present the export demand for lambs can hardly be met.
