SOME PRODUCTION TRAITS OF THE NEW IMPORTED EAST-FRIESIAN SHEEP IN MACEDONIA**

**Plenary invited paper Abstract: Investigation of some production traits in two production years (2005, 2006) was carried out on East-Friesian sheep. Considerably (P<0.01) higher milk production (346 lit.) in 2005, in comparison to 2006 (250 lit.) was registered. The duration of lactation is considerably (P<0.01) greater in 2006 (264 days), compared to 2005 (232 days). The content of milk fat in the milk from this breed is in average 5.01%, i.e. 5.64%, for the two years consequently. The production of milk fat is 17.34 kg in 2005 and 14.11 kg in 2006. The percentage of proteins in our research, in average is 4.68 % in 2005, i.e. 4.85 % in 2006, while the production is 16.19, i.e. 12.12 kg. The number of obtained lambs per sheep is not considerably higher (P<0.05) in 2005 (1.64 lambs) in comparison to 2006 (1.48 lambs). Almost all the examined factors (year, lactation, number of milk control) highly influence (P<0.001) the daily milk production, with the exception of the year, which influences with a considerable importance (P<0.05) the evening milk. In regard to the milk fat, statistically highly significant (P<0,001) influence was established only of the number of sequence and the month of the milk control, while all the rest fixed factors (year, lactation, number of lambs) didn’t influence significantly (P>0,05) this component of milk. Except of the fats, all the examined factors influenced statistically highly significantly (P<0,001) proteins in the milk, with an exception of the number of lambs, which did not influence considerably (P>0,05) this component
