Sažetak
This paper analyses the methods used to improve reproductive success on the Klaban family sheep farm. The
research was carried out on the basis of archive data collected during two consecutive reproductive seasons. In the
first part, the effect of flushing administered before the expected start of the reproductive season was analysed
and compared with the control season. The positive results of flushing were shown in the higher average number
of lambs born per ewe and the lower number of stillborn lambs. In the second part of the study, archive data were
analysed on birth weight and its increase in lambs, as well as the milk fat content of milk in crossbred sheep. The
main focus was on the Romanov breed, which is intended as a basis for future improvement and renewal of the
flock. Initially, Romanov sheep were crossed with a Clun forest ram, resulting in the F1 generation. The female offspring of the F1 generation were mated with a purebred ile de France ram to further enhance the meatiness, feed conversion, and daily weight gain of the final F2 generation, which was intended for market placement. The milk fat content of the F1 generation ewes was significantly higher compared to the purebred Romanov ewes. The daily weight gain and final weight at 105 days of age of the F2 generation lambs was significantly higher than that of the F1 generation lambs. On the basis of the analysed data, it was concluded that the implementation of an appropriate feeding regime and selection of high-quality lambs with good genetics for flock renewal are important methods to improve reproductive management. By implementing them, better results can be achieved in sheep breeding.
