Abstract

Penelitian dilaksanakan di Pamudji Farm di Kecamatan Ngantang Kabupaten Malang dari bulan Juni sampai Juli 2011. Tujuan penelitian untuk mengetahui korelasi fenotipik efisiensi reproduksi dan produksi susu pada sapi perah PFH. Hasil penelitian diharapkan dapat digunakan sebagai penduga produktivitas ternak sapi perah dan bahan kajian informasi reproduksi pada induk sapi perah PFH dengan produksi susunya. Materi penelitian adalah data produksi susu dan data sifat reproduksi dari 26 ekor sapi perah hingga laktasi ketiga. Metode penelitian yang digunakan studi kasus dengan pengambilan data secara purposive sampling. Data yang diambil dengan kriteria yaitu jenis sapi PFH hingga laktasi ketiga dengan kelahiran normal, sedangkan variabel yang diamati adalah service per conception , calving interval , days open dengan produksi susu perlaktasi. Data yang diperoleh dianalisa dengan menggunakan korelasi dan regresi linier sederhana. Hasil penelitian menunjukkan bahwa nilai rata-rata service per conception, calving interval, days open dan produksi susu secara berurutan adalah 2,01±0,73; 374,86±25,37 hari; 117,63±91 hari dan 3709,64±492,42 liter. Persamaan regresi service per conception dari laktasi pertama sampai ketiga secara berurutan adalah Y=3370,37±226,46X; Y=3358,05+208,33X dan Y=3684,57-100,75X. Untuk nilai koefisien korelasinya (r) adalah 0,25; 0,26 dan -0,13. Koefisien determinasinya (R²) adalah 6,25%; 6,76% dan 1,69%. Pada calving interval persamaan regresi laktasi kedua dan ketiga adalah Y=3859,19-0,26X dan Y=6045,78-6,93X. Untuk nilai koefisien korelasinya (r) adalah -0,01 dan -0,25. Koefisien determinasinya (R²) adalah 0,01% dan 6,25%. Pada days open persamaan regresi laktasi kedua dan ketiga adalah Y=3700,68+0,52X dan Y=3517,94-0,18X. Untuk nilai koefisien korelasinya (r) adalah 0,01 dan -0,006. Koefisien determinasinya (R²) adalah 0,01% dan 0,036%. Tidak terdapat hubungan yang nyata antara efisiensi reproduksi dan produksi susu pada laktasi I sampa laktasi III. Disimpulkan bahwa terdapat korelasi positif rendah antara service per conception dan produksi susu pada laktasi I dan II, dan korelasi negatif rendah pada laktasi III. Terdapat korelasi negatif rendah antara calving interval dan produksi susu pada laktasi II dan III. Terdapat korelasi positif rendah antara days open dan produksi susu pada laktasi II dan korelasi negatif rendah pada laktasi III. Disarankan dalam pemeliharaan sapi perah PFH perlu perbaikan manajemen pemeliharaan yang lebih baik terutama pada penanganan reproduksi sapi betina (nilai S/C=1, CI=12 bulan, DO=100 hari) dan produksi susu (4500-5500) karena berhubungan dengan manajemen pakan dan biaya pemeliharaan, penambahan tenaga kerja serta perlu dilakukan penelitian lebih lanjut tentang korelasi efisiensi reproduksi dan produksi susu sehingga diharapkan peternak tidak merugi.
