Abstract
This study was aimed to examine level supplemenation of corn oil (CO) as a source of protected poly unsaturated fatty acids (PUFA) and various crude protein (CP) levels in diets to ruminal iodin number and milk fatty acids of Friesian Holstein. The research done through two stages, using in vivo method and in vivo method. The corn oil protection is performed by saponification using KOH and then tranformed using CaCl2 to calcium salt. Research use two treatment factors with three replications, the first factor was supplementation of PUFA (L) with details L0 (Without protection), L1 (supplementation 75% Protected CO), and L2 (Supplementation 80% Protected CO) and the second factor is the P1 crude protein level (CP 12%) and P2 (CP 16%). The results showed that there was no interaction effect between the supplementation of protected CO with protein level to the ruminal iodin number, saturated fatty acid (SFA), unsaturated fatty acid (UFA), linoleic acid (LA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acid (PUFA) milk. The parameters are iodin number and milk fatty acids. Result of this research show that supplementation of protected CO increased the ruminal iodin number (P<0.01), UFA (P=), LA (P=) and milk PUFA (P=). Supplementation protected CO decrease milk SFA (P=). It can be concluded that supplementation of protected CO increases milk UFA of FH.

Summary
Asam lemak susu terdiri atas dua jenis berdasarkan tingkat kejenuhannya, yaitu asam lemak jenuh dan asam lemak tidak jenuh. Reis et al (2012) mengungkapkan bahwa penambahan garam kalsium asam lemak tidak jenuh ganda mampu meningkatkan produksi susu sapi Friesian Holstein (FH) secara signifikan sejak awal laktasi sampai akhir laktasi. Wina et al (2014) dalam laporannya menyatakan bahwa penambahan garam kalsium asam lemak tidak jenuh sebesar 2,5% dari bahan kering (BK) ransum mampu meningkatkan produksi susu sebesar 7,41%. Sementara itu Gawad et al (2015) menunjukkan bahwa minyak biji rami yang diproteksi dengan garam kalsium sebesar 86% mampu menurunkan asam lemak jenuh dari 68,8% menjadi 46,6%, dan meningkatkan asam lemak tidak jenuh ganda dari 7,83% menjadi 30,71%. Selain dapat menurunkan kolesterol darah, rasio asam linoleat sebagai omega-6 dengan asam linolenat sebagai omega-3 (þ6/þ3) yang direkomendasikan oleh WHO dan FAO sebesar 5:1 – 10:1 (Arbex et al, 2015). Berdasarkan latar belakang tersebut, penelitian ini bertujuan untuk mengkaji pengaruh penambahan minyak jagung terproteksi dalam bentuk garam kalsium terhadap peningkatan asam lemak tidak jenuh susu sapi FH, khususnya asam linoleat susu sapi, sehingga diperoleh sebuah pangan fungsional
