Highlights
Dairy sheep sector is a traditional branch of livestock sector in Slovakia
Fat and protein contents and factors affecting their variation in dairy sheep were studied in detail (Oravcová et al, 2006, 2007)
Correlation coefficients between transformed somatic cell count (SCC) and milk traits obtained in our study differed from literature (Riggio et al, 2007; Olechnowicz et al, 2009): slightly stronger relationships were found for Valle del Belice ewes and for Polish Line 05 ewes
Summary
Dairy sheep sector is a traditional branch of livestock sector in Slovakia. Local breeds: Tsigai (TS) and Improved Valachian (IV) are the most numerous breeds. Productive specialized dairy breeds: East Friesian and Lacaune (LC) were launched in the 1970s and 1990s, respectively. In order to increase milk yield of local breeds, two- and threebreed crossbred composite populations (either on base of TS or IV) were formed during two last decades. Fat and protein contents and factors affecting their variation in dairy sheep were studied in detail (Oravcová et al, 2006, 2007). Daily milk yield, fat and protein contents are good determinants of the quality of sheep milk, and somatic cell count (SCC) is an important udder health indicator (Abdelgawad et al, 2016). Mastitis is a costly health problem in dairy ewes (Arias et al, 2012); mammary infections damage udder tissue
