Özet

his study was carried out to determine the effects of high and low somatic cell counts (SCC)on milk composition and yield of Saanen goats. The goats were divided into 2 groups and put into trials during the 1stmonth of their lactation. The 2 groups were selected as those with ≤500 cell/mL(low SCC group (E)) and ≥500 cell/mL (high SCC group (T)) with each group consisting of 10goats. It was observed that the T group hada high SCC, which resulted in a significant effect on milk yield, compared to the T group with a low SCC (P<0.05; 1.34vs2.02 kg/day-1). Similarly, the milk samples that were taken from group T had lower (P<0.05) levels of milk lactose and Solids not fat (SNF) percentages than group E (milk lactose=4.15 and 4.65 %, SNF=8.41and 9.23% respectively). However, the effects of SCC on the fat and protein percentages of the milk were not significant (P>0.05). This study also displayed a statistically significant negative correlation between SCC and lactose content (-0.607), as well as daily milk production (−0.673) and SNF (- 0.850).
