Abstrak: The addition of poly unsaturated fatty acid (PUFA) in feed is needed for energy source and reproductive function. However, fat supplementation to the diet can disrupt the fermentation system, microbial population in the rumen, and limit the synthesis by rumen microbes. The objective of this research was to study the influences of feed containing different sources of unsaturated fatty acid on protozoa population, rumen fermentability, the urinary allantoin excretion rate, and the nitrogen (N) balance in the body. Twelve three-months old post weaning local female sheep were used in this study. The sheep were allocated in a Randomized Block Design and divided into three groups based on body weight and subjected to four treatments. Four treatments were M0 = control diet, MJ = diet containing 1.5% corn oil, MIL = diet containing 1.5% lemuru fish oil, MILT = diet containing 1.5% protected lemuru fish oil. Data were analyzed using analysis of variance and any significant differences were further tested using contrast orthogonal. The results showed that the protozoa population, ruminal NH3 level, excretion of allantoin, and N retention were not affected (P>0.05) by dietary supplementation, but the volatile fatty acid (VFA) level was very significantly (P<0.01) increased with the addition of corn oil (171.49 mM) and lemuru fish oil (141.42 mM). It is concluded that different sources of unsaturated fatty acid supplementation had no influence in protozoa population, rumen activity, and urinary allantoin, but could improve the rate of VFA.

Judul: Fermentability and Digestibility of Spray Drying-Protected High PUFA-Containing Vegetable Oil in Dairy Cow Rations In Vitro
Abstrak: Penelitian ini bertujuan menguji penambahan minyak nabati kaya PUFA terproteksi dengan metode pengeringan semprot pada ransum sapi perah secara in vitro. Penelitian ini menggunakan RAK faktorial 3×4 dengan 3 kelompok sebagai ulangan. Faktor yang diuji meliputi jenis minyak (M) yaitu minyak jagung (M1), minyak biji bunga matahari (M2), minyak wijen (M3) dan taraf pemberian (T) yaitu T0-T3 berturut-turut sebesar 0% (kontrol), 1%, 2%, dan 3%. Parameter yang diuji meliputi pH, populasi protozoa dan bakteri total, konsentrasi NH3 dan VFA total, serta KcBK dan KcBO. Hasil penelitian menunjukkan tidak adanya interaksi antara jenis minyak dan taraf pemberian terhadap seluruh parameter yang diuji. Jenis minyak dan taraf pemberian tidak berpengaruh nyata (P>0,05) terhadap nilai pH dan KcBO. Jenis minyak berpengaruh nyata (P<0,05) dalam meningkatkan populasi bakteri total dan konsentrasi VFA total, sedangkan taraf pemberian berpengaruh nyata (P<0,05) dalam meningkatkan konsentrasi VFA total serta menurunkan populasi protozoa dan bakteri total, konsentrasi NH3, dan KcBK. Pemberian minyak jagung mampu meningkatkan populasi bakteri total serta konsentrasi VFA total dengan taraf optimal hingga 2%., This study aimed to test the addition of vegetable oil rich in protected PUFAs by spray drying method in dairy cow rations in vitro. This study used a 3×4 factorial Randomized Group Design with 3 groups as replicates. The factors tested were the type of oil (M), consisting of corn oil (M1), sunflower seed oil (M2), sesame oil (M3) and the level of use (T), consisting T0-T3 at 0% (control), 1%, 2%, and 3%. Parameters tested included pH, protozoa and total bacteria populations, total NH3 and VFA concentrations, dry matter and organic matter digestibility. The results showed no interaction between the type of oil and the level of use on all parameters tested. Oil type and level of use had no significant effect (P>0.05) on pH value and organic matter digestibility. Oil type significantly (P<0.05) increased total bacterial population and total VFA concentration, while the level of use had a significantly (P<0.05) increased total VFA concentration and decresed protozoa population, total bacterial population, NH3 concentration, and dry matter digestibility. The addition of corn oil increased the total bacterial population and total VFA concentration with an optimal level of up to 2%.
