PENGARUH PEMBERIAN COMPLETE FEED DENGAN UNDEGRADED PROTEIN TERHADAP KUALITAS SUSU SAPI PERANAKAN FRIESIAN HOLSTEIN Graita Ayu Kemawati 05/186306/PT/04936 INTISARI Penelitian ini bertujuan untuk mengetahui pengaruh pemberian complete feed dengan undegraded protein (UDP) terhadap kualitas susu sapi peranakan Friesian Holstein. Enam ekor sapi PFH laktasi bulan kedua dengan rerata berat badan 325 kg dan produksi susu rata-rata 10 liter per hari dibagi menjadi dua kelompok (A dan B) untuk pakan kontrol dan treatment. Masing-masing kelompok terdiri dari 3 ekor sapi. Pakan treatment yaitu complete feed dengan UDP berupa menir kedelai yang diproteksi dengan formaldehid. Pakan diberikan secara berturut-turut selama 5 bulan, masing-masing kelompok diberi pakan kontrol dan treatment secara cross over. Pada periode pertama kelompok A mendapat pakan kontrol dan kelompok B mendapat pakan treatment, sedangkan pada periode kedua kelompok A mendapat pakan treatment dan kelompok B mendapat pakan kontrol. Pengambilan sampel susu dilakukan pada fase koleksi, susu pagi dan sore hari masing-masing diambil secara proposional sebanyak 10% dari produksi kemudian dikomposit dan dilakukan analisis kualitas susu meliputi kadar protein, lemak, solid non fat (SNF), formaldehid dalam susu, dan berat jenis (BJ). Data yang diperoleh dianalisis menggunakan analisis variansi Cross Over Design. Hasil penelitian menunjukkan bahwa terdapat perbedaan yang nyata pada konsumsi bahan kering (11,12 kg vs 11,30 kg) dan tidak ada perbedaan nyata pada produksi susu (7,65 lt/hr vs 7,25 lt/hr), kadar protein susu (2,61% vs 2,65%), kadar lemak susu (3,35% vs 3,16%), BJ susu (1,026 vs 1,027), dan SNF susu (7,22% vs 7,44%) serta uji formaldehid pada susu menunjukkan hasil negatif. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa pemberian complete feed dengan UDP pada sapi Peranakan Friesian Holstein dapat mempengaruhi konsumsi bahan kering tetapi tidak menyebabkan perubahan produksi dan kualitas susu serta tidak terdapat residu formaldehid di dalam susu yang dihasilkan.

THE EFFECT OF UNDEGRADED PROTEIN ON COMPLETE FEED IN MILK QUALITY OF FRIESIAN HOLSTEIN CROSSBRED Graita Ayu Kemawati 05/186306/PT/04936 ABSTRACT The research was to investigate the effect of undegraded protein on complete feed in milk quality of Friesian Holstein Crossbred. Six second month of lactated cows with 325 kg average initial body weight and have ten litter milk productions per day, randomly divided in two groups (group A and B) of treatments. Feed treatment was complete feed with undegraded protein, consist of broken soybean which was protected of formaldehyde. The animals were fed for five months, following crossed over design. In the first period, group A was fed with control ration and group B was fed with treatment, while in the second period group A was fed with treatment and group B was fed with control. Milk sample were collected two times a day approximately 10% of total production in the morning and afternoon. Samples were then composited and analyzed for protein, fat, solid non fat, formaldehyde, and the milk density. Data collected were subjected to analysis of variance following crossed over design. Results showed that there was significant difference in the total intake of dry matter (11.12 kg vs 11.30 kg) and there were no effect of treatment on milk production (7.65 lt/day vs 7.25 lt/day), milk protein (2.61% vs 2.65%), milk fat (3.35% vs 3.16%), milk density (1.026 vs 1.027), and solid non fat (7.22% vs 7.44%) and analyzed for formaldehyde result showed negative. It can be concluded that feeding complete feed with undegraded protein for Friesian Holstein Crossbred, yielded significantly difference in total intake of dry matter but not affected milk production and milk quality. There was also no formaldehyde residue found in milk produced. Key Words: Friesian Holstein Crossbred, Undegraded Protein, Complete Feed, Milk Quality
