      Abstract
      Secara eksternal, ciri fisik bagian tubuh tertentu pada sapi perah dapat dijadikan acuan untuk menentukan kapasitas produksi, salah satunya melalui kondisi ambing. Penelitian ini bertujuan untuk mengetahui suhu ambing sebelum dan sesudah pemerahan serta korelasinya dengan produksi susu sapi Friesien holstein. Penelitian menggunakan 14 ekor sapi Friesien holstein pada periode laktasi dua sampai empat yang bebas mastitis. Suhu ambing sebelum dan sesudah pemerahan diukur pada 4 titik corpus ambing yang berbeda menggunakan alat thermometer infrared selama 3 hari berturut-turut. Data dianalisis menggunakan metode analisis regresi linear sederhana dan korelasi product moment Pearson. Rataan selisih suhu ambing sebelum dan setelah pemerahan sebesar 1,90±0,47 oC (pagi) dan 1,19±0,49 oC (sore) (P<0,05). Suhu ambing sebelum pemerahan (T0P dan T0S) dan nilai penurunan suhu ambing pagi hari (ΔTP) menunjukan korelasi positif (r0P= 0,65; r0S= 0,85; rΔTp= 0,76) terhadap produksi susu (P<0,05) dengan nilai koefisien determinasi 42,49%, 72,98%, dan 57,58%. Terdapat hubungan antara suhu ambing dengan produksi susu pada sapi perah yang bebas mastitis
       
      Externally, the physical characteristics of certain body parts in dairy cows can be used as a reference to determine milk yield, one of which is through the condition of the udder. This study aims to determine the temperature of the udder pre- and post- milking and its correlation with the milk yield of Friesien holstein cows. The study used 14 Friesien holstein cows in the second to fourth lactation period which free from mastitis. The temperature of the udder pre- and post- milking was measured at 4 different points of the udder corpus using an infrared thermometer for 3 consecutive days. Data were analyzed using simple linear regression analysis and Pearson product moment correlation method. The mean difference in udder temperature pre- and post- milking was 1,90±0,47 oC (morning) and 1,19±0,49 oC (afternoon) (P <0,05). The temperature of the udder pre- milking (T0P and T0S) and the decrease in udder temperature in morning milking (ΔTp) showed a positive correlation (r0P= 0,65; r0S= 0,85; rΔTp= 0,76) on milk production (P<0,05) with a coefficient of determination 42,49%, 72,98% and 57,58%. There is a correlation between udder temperature and milk yield in dairy cows which free from mastitis.
