Relationship Between Udder Phenotypic Characteristics and Milk Quality in Dairy Cows
Abstract
This study was conducted to investigate the relationship between somatic cell count (SCC) and
some udder properties of Holstein cows at an intensive dairy farm. Phenotypic udder measurements were taken
and cows were classifed as Group I (cows with ideal udder characteristics) and Group II (cows without ideal
udder characteristics). The relationships between SCC and udder characteristics and between SCC and milk yield
and characteristics were assessed. Also, the effects of lactation number (1, 2, 3, 4), lactation periods (1, 2, 3) and
the control weeks were also investigated in each group. The effect of group (P<0.01), lactation number (P<0.05),
lactation period (P<0.01) and control weeks (P<.05) on SCC were found to be signifcant, but the interactions were
not found to be signifcant (P>0.05). SCC was found to be 5.04±0.09 Log10SHS cells ml-1 in Group I and 5.35±0.08
Log10SHS cells ml-1 in Group II. The effect of group on milk yield, pH and conductivity was found to be signifcant
(P<0.01). The values for Group I and Group II were respectively determined as 34.79±0.91 lt and 30.15±0.81 lt for
milk yield, 6.96±0.02 and 7.02±0.01 for pH and 5.59±0.26 and 6.84±0.23 for conductivity. Correlation analyses
revealed highly signifcant negative correlation (-0.258) between SCC and milk yield, highly signifcant positive
correlation (+0.552) between SCC and pH and again highly signifcant positive correlation (+0.278) between SCC
and conductivity. Current fndings revealed that udder phenotypic characteristics should be taken into account to
improve milk quality since non-ideal udders may negatively influence milk quality
