Penelitian bertujuan untuk menqetahui penqaruh sistem pemberian pakan secara complete feed (CF ) dan free choice ( FC) terhadap pertumbuhan sapi dara Friesian Holstein ( FH ), dilaksanakan di Laboratorium Ternak Perah , Fakultas Peternakan UGM, selama enai bulan. Dua belas ekor sapi dara FH berumur rata-rata 10 bulan denqan berat rata-rata 121,92±1,98 Kq, secara acak dibaqi menjadi dua kelompok. Kelompok I diberi pakan denqan sistem CF denqan imbanqan bahan kerinq hijauan bandinq konsentrat 60:40, sedanqkan kelompok II diberi pakan secara FC, dimana hijauan dan konsentrat diberikan secara terpisah. Baik kelompok I maupun kelompok II keduanya diberi pakan secara ad libi- tum. Data diuji statistik denqan uji-t. Hasil analisis statistik menunjukkan bahwa konsumsi bahan pakan ( bahan kerinq ), protein kasar, dan enerqi (total digestible nutrients ) dan pertambahan berat badan harian terdapat perbedaan ( P <0,01) secara rata-rata kelompok II lebih tinqqi daripada kelompok I. Temperatur rektal dan frekuensi denyut jantunq tidak beda nyata, tetapi terdapat perbedaan ( P <0,01 ) pada frekuensi respirasi. Sistem pemberian pakan tidak menunjukkan adanya perbedaan yanq nyata terhadap konversi pakan. Disimpulkan bahwa sistem pemberian pakan FC memberikan penqaruh terhadap pertumbuhan yanq lebih tinqqi dibandinq sistem CF sehinqqa berat siap kawin yanq direkomendasikan akan lebih cepat dicapai.

The study was conducted to investigate the effects of complete feed ( CF ) and free choice (FC) feeding systems on growth of Friesian Holstein heifers. The study took place at Dairy Laboratory Faculty of Animal Husbandry, Gadjah Mada University , for six months. Twelve heifers of Friesian Holstein, approximately 10 months of age with the average liveweight 121,92±1,98 kg, were randomly grouped into two treatments. The treatment I was feeding with CF with dry matter rasio of 60:40, and treatment II was FC feeding system, with separate forage and concentrates. Both group I and group II were given ad libitum. The data were analyzed by t-test. The result indicated that there were significant difference ( P <.01)\ between group I and group II on feed consumptions dry matter, crude protein and total digestible nutrients consumptions of Group II were greater ( P <.01) those of Group I. Rectal temperature and pulsus rate were no differences significantly, but there was difference significantly on respiration rate ( Pc.01). Feeding systems indicated difference on total feed conversion. It was concluded that body weight of FC for breeding tended to be achieved earlier than that of CF.
