Penelitian ini bertujuan untuk mengetahui korelasi produksi susu terkoreksi periode laktasi satu sampai empat dengan produksi susu pemerahan pagi dan sore hari. Penelitian dilakukan di Balai Besar Pembibitan Ternak Unggul dan Hijauan Pakan Ternak (BBPTU-HPT) Baturraden, Purwokerto, Jawa Tengah. Data sapi perah laktasi 1 yang digunakan pada penelitian sebanyak 99 ekor, laktasi 2 sebanyak 59 ekor, laktasi 3 sebanyak 36 ekor dan laktasi 4 sebanyak 32 ekor. Data ini dikoleksi dari tahun 2007 sampai 2013. Produksi susu pagi, sore dan total setiap periode laktasi dilakukan standarisasi ke panjang laktasi 305 hari menggunakan faktor koreksi (FK) kemudian dikorelasikan. Hasil penelitian menunjukan rataan produksi susu tertinggi terjadi pada periode laktasi 4 sebanyak 4539,33 kg dan yang terendah terjadi pada laktasi 1 sebanyak 3260,59 kg. Produksi susu terkoreksi tertinggi terjadi pada periode laktasi 4 sebanyak 4539,33 kg dan yang terendah terjadi pada laktasi 1 sebanyak 3260,59 kg. Nilai korelasi antara produksi susu pagi dan sore terkoreksi dengan interval pemerahan 12:12 termasuk katagori sangat tinggi yaitu 0,91. Nilai korelasi produksi susu pagi dan sore terkoreksi dengan produksi susu 305 terkoreksi termasuk katagori sangat tinggi yaitu 0,98 dan 0,97.

The production of milk in the morning, in the afternoon, and the total of milk from each lactation were standardized to 305 days, using the factor of correction and then it was correlated. The result of this research showed of the highest production occurred at the fourth lactation which was 3850,25 kg, and the lowest occurred at the first lactation which was 2584.53 kg.
