摘要:
In this research, the relationship among milk yield, somatic cell count and linear type traits were examined to the 29 head Holstein Friesian cows reared at the Kahramanmaras Sutcu Imam University's Animal Progressing and Practicing Farm (HAYMER). The relationship among milk yield, somatic cell count and linear type traits were searched. Somatic cell counts were determined from collecting milk samples on December 2012 to November 2013 in morning or evening milking time once a month. In this study, average 305 days milk yield was determined as 3111 +/- 133.5 kg, 2.44 +/- 0.69 logshs somatic cell count average was 419.88 +/- 67.5*10(3) cell/ml and the relationship among milk yield, logshs and somatic cell count wasn't found statistically significant. Logshs lowest average value of 2.425 +/- 0.138 compared to the control month (May) and the highest logshs value of 0.142 +/- 2.557 (March), respectively. From teat measurements, the relationships among somatic cell and front teats diameter, rear teats distance, rear teats length was detected significant (P< 0.05). Also, the relationship between the diameter of the front teats in milk yield was significant (P< 0.05).
