Penelitian ini bertujuan untuk mengetahui pengaruh pemberian complete feed dengan kedelai terproteksi terhadap produksi dan kualitas susu sapi peranakan Friesian Holstein. Penelitian ini menggunakan 6 ekor sapi Peranakan Friesian Holstein (PFH) dengan berat badan 334±36,5 kg yang dibagi dalam 2 kelompok perlakuan dan masing-masing diberi pakan kontrol (P1) dan complete feed dengan kedelai terproteksi (P2) secara cross over pada bulan ke-3 dan bulan ke-5 masa laktasi. Variabel yang diukur meliputi konsumsi bahan kering, kecernaan bahan kering, produksi susu harian, dan kualitas susu. Konsumsi bahan kering menunjukkan perbedaan nyata (P<0,05) pada P1 11,12 kg lebih rendah dibandingkan P2 11,30 kg. Kecernaan bahan kering menunjukkan perbedaan yang sangat nyata (P<0,01) pada P1 76,14% lebih tinggi daripada P2 70,05%. Produksi susu, kadar lemak, protein dan total solid menunjukkan perbedaan tidak nyata antara P1 dan P2. Rata-rata produksi susu P1 7,649 liter/hari dan P2 7,248 liter/hari. Lemak susu, protein dan total solid berturut-turut 3,29%, 2,61%, dan 11,12% pada P1 dan 3,24%, 2,65%, dan 11,15% pada P2. Berat jenis susu menunjukkan perbedaan yang nyata (P<0,05) pada P1 1,025 lebih rendah dibandingkan P2 1,026. Asam lemak tidak jenuh berupa asam linolenat dan asam cervonik pada P1 lebih tinggi daripada P2 (P<0,05) berturut-turut 0,16 (mg/100ml) dan 0,07 (mg/100ml) pada P1 dan 0,14 (mg/100ml) dan 0,05 (mg/100ml) pada P2. Disimpulkan bahwa complete feed dengan kedelai terproteksi dapat dijadikan alternatif pakan sapi perah.

The objective of the study was to find out the effect of complete feed with protected soybean on the production and quality of milk from Friesian Holstein crossbred dairy cows. It used six Friesian Holstein crossbred dairy cows with initial body weight of 334+36.5 kg were devided into two groups, and each was given control feed (P1) and complete feed with protected soybean (P2) using crossed over design at the third and fifth months of lactation period. Variables measured were dry matter intake (DMI), digestibility, daily milk production, and milk quality. The DMI showed that there were a significant differences (P<0.05), i.e. in P1 of 11.12 kg lower than that of P2 of 11.30 kg. The digestibility showed that there were a very significant differences (P<0.01), i.e. in P1 of 76.14% higher than that P2 of 70.05%. The milk production, fat content, protein, and total solid showed that there were no significant differences between P1 and P2. Average production of milk at P1 was 7.649 liter/day, while P2 was 7.248 liter/day. Milk fat, protein and total solid in P1 were 3.29%, 2.61% and 11.12%, respectively, while P2 were 3.24%, 2.65%, and 11.15%, respectively. The specific mass of milk showed that there were a significant differences (P<0.05), i.e. in P1 of 1.025 lower than in P2 of 1.026. The unsaturated fatty acids of linoleic acid and cervonic acid in P1 were 0.16 (mg/100ml) and 0.07 (mg/100ml), respectively, higher than that P2 of 0.14 (mg/100ml) and 0.05 (mg/100 ml), respectively (P<0.05). It can be concluded that complete feed with protected soybean can be used as an alternative feed for dairy cows.
