The comparison of external udder measurements of the sheep breeds Improved Valachian, Tsigai, Lacaune and their crosses
Popis výsledku v původním jazyce
Morphological udder traits have recently become of greater interest from farmers to researchers. In dairy ewes, the udder is very important due to its physiological and conformational characteristics. External udder traits were measured in ewes (Ovis aries L.) of nine genotypes (355 ewes) created of the basis of Improved Valachian (IV), Tsigai (T), and Lacaune (LC) breeds (six traits; 1185 data for each trait) during the milking period 2002-2008. Udder measurements were assessed for: udder length (UL),udder width (UW), rear udder depth (RUD), cistern depth (CDE), teat length (TL), and teat angle (TA). Data were processed by restricted maximum likelihood (REML) methodology using a MIXED procedure from the SAS statistical package. All studied parameterswere influenced by the genotype (P < 0.001), many of them also by the effect of parity and lactation stage. The exactly detected UL, UW and RUD during the lactation and with the age of ewes expand gradually (P < 0.001). Teat length was g
