| Özet |
| This study was conducted to assess the impact of somatic cell count (SCC) on the test day milk yield (TDMY) and milk composition parameters (fat, solids-not-fat, protein and lactose) of Holstein cows raised in the Kırşehir province of Turkey. A total of 1194 raw milk samples were collected from 195 Holstein cows at different stages of lactation (from 1 to 7), parities (from 1 to 3) and calving seasons (autumn, winter, spring and summer). Also, TDMY and milk composition traits were tested by SCC in four groups (< 100× 103, 100-200× 103, 201-500× 103 and> 500× 103 cells/mL). For statistical evaluation, SCC data were converted to log10 base. The overall means of log10SCC, TDMY, fat, solids-not-fat (SNF), protein and lactose were determined as 4.95±0.016, 33.36±0.232 kg/day, 3.39±0.021%, 9.04±0.013%, 3.32±0.005% and 4.92±0.007%, respectively. Log10SCC, TDMY, fat, SNF, protein and lactose were significantly affected by the stage of lactation, parity and calving seasons (P< 0.05). An increase in the SCC was accompanied by a decrease in the milk yield as well as its content (P< 0.05). Cows’ milk with high SCC (> 201× 103 cells/mL) had a lower TDMY than milk with lower SCC (< 100× 103 and 100-200 cells/mL). However, the lowest fat, SNF, protein and lactose were determined in milk with SCC> 500× 103 cells/mL. It was concluded that SCC in milk should not exceed 500× 103 cells/mL for Holstein cows, suggesting that monthly control of SCC may be effective for improving milk production and milk quality in Holstein cows. |
