AN INVESTIGATION ON RELATIONSHIP BETWEEN LACTATION MILK YIELD, SOMATIC CELL COUNT AND UDDER TRAITS IN FIRST LACTATION TURKISH SAANEN GOAT USING DIFFERENT STATISTICAL TECHNIQUES

WOS: 000323878500002This study aimed to determine the relationship between lactation milk yield, (LMY), somatic cell count (SCC), and udder traits using some statistical techniques, viz. multiple linear regression, stepwise regression, use of factor analysis in multiple regression, and regression tree. Forty six Turkish Saanen Goat were used in the present investigations. These goats were milked with milking machine twice a day. The traits recorded were: daily milk yield (DMY), udder upper height (UUH), udder width (UW), udder length (UL), udder diameter (UD), teat angle (TA), udder volume (UV), somatic cell count (SCC), lactation length (LL), and lactation milk yield (LMY), Respectively. In the multiple linear regression analysis, significant effects of and LT (P 191 days among the goats with TA < 50 degrees provided higher LMY average except for Node 2. If there is a verification at genetic level, the relationship between lactation milk yield (LMY), somatic cell count (SCC), and udder traits might contribute to further goat breeding to increase milk yield in the future
