Sažetak
This research presents the evaluation of the reproductive performance of Pomeranian sheep, bred in the Baldram conservation herd (Elblag province) over two consecutive years. The number of evaluated ewes in the selected farm was: 66 mated (including 61 lambing) in 2004 and 74 mated (including 74 lambing) in 2005. Fertility in 2004 was recorded at 92.4%, while the same in 2005 was 100.0%, prolificacy values were respectively: 155.7% and 139.2%,
lamb rearing: 98.9% and 87.4%, and reproductive performance: 142.4% and 121.6%. The comparison of different time periods revealed a decline in the values of the reproductive parameters. Out of 198 lambs born in both years, 46.5% constituted ram lambs and 53.5% ewe lambs. Among the birth types, litters with single lamb were dominant (54.1%), while litters with twins constituted only 45.2%. Over the two years analysed, there was only 1 litter with
triplets. On the basis of the results gathered, it can be concluded that the mean values of the reproductive indices, for both years of Pomeranian sheep breeding in the Baldram herd, do not
