ABSTRAK Penelitian ini bertujuan untuk menyelidiki pengaruh dari pemberian pakan yang mengandung mikroenkapsulasi minyak kanola pada konsumsi, kecernaan nutrien, dan performa pertumbuhan pada domba. Lima belas domba garut jantan dengan rataan bobot badan awal 20.17 ± 4.65 kg digunakan dalam rancangan acak kelompok (RAK) pada periode pemeliharaan selama 100 hari dengan 3 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan yang digunakan adalah P0 (kontrol / hijauan: konsentrat = 60:40), P1 (P0 mengandung 4% minyak kanola), dan P2 (P0 mengandung 4% mikroenkapsulasi minyak kanola). Hasil yang diperoleh dalam penelitian ini menunjukkan bahwa tidak ada perbedaan untuk performa, konsumsi dan kecernaan nutrien. Suplementasi minyak kanola murni maupun terenkapsulasi sebagai sumber energi dalam ransum domba, menghasilkan pertambahan bobot badan harian (PBBH) dan efisiensi penggunaan pakan yang terbaik. Proporsi asam lemak tak jenuh pada perlakuan suplementasi mikroenkapsulasi minyak kanola 8% lebih tinggi dibandingkan dengan kontrol. Perlakuan minyak kanola murni meningkatkan (P<0.05) proporsi asam stearat (C18:0) dibandingkan perlakuan lainnya. Sehingga, dapat disimpulkan bahwa suplementasi 4% mikroenkapsulasi minyak kanola di dalam ransum, selaian menghasilkan PBBH dan efisiensi pakan terbaik juga mampu melindungi asam lemak tak jenuh (ALTJ) dari proses biohidrogenasi rumen tanpa mengganggu konsumsi dan kecernaan nutrient ransum.Kata kunci: konsumsi, kecernaan, mikroenkapsulasi, minyak kanola, performaABSTRACTThe aim of this study was to investigate the effects of feeding diets with microencapsulation of canola oil on intake, nutrient apparent digestibility, and growth performance of lambs. Fifteen male garut lambs with an initial average body weight of 20.17 ± 4.65 kg were used in a randomized block design (RBD) for a 100-days feeding period with 3 treatments and 5 groups as replication. The treatments were P0 (control/forage:concentrate = 60:40), P1 (P0 contained 4% of canola oil), and P2 (P0 contained 4% of microencapsulated canola oil). The results showed that there was no difference in the growth performance, intake, and digestibility of nutrients. The best of average daily gain (ADG) and feed efficiency results from the supplementation of pure canola oil or encapsulated canola oil in diets. The proportion of unsaturated fatty acids in the supplementation of microencapsulated canola oil treatment was 8% higher than control. The treatment of canola oil supplementation increased (P<0.05) the proportion of stearic acid (C18:0) compared to other treatments. Thus, it can be concluded that supplementation of 4% of microencapsulated canola oil, besides produced the best of ADG and feed efficiency, was also able to maintain unsaturated fatty acids from the rumen biohydrogenation process without detrimental effects on nutrient intake and digestibility in lambs. Keywords: canola oil, digestibility, intake, microencapsulation, performance

ABSTRAK Penelitian ini bertujuan untuk menganalisis pengaruh minyak kanola tanpa proteksi dan terenkapsulasi pada karakteristik fermentasi rumen. di domba garut jantan. Penelitian menggunakan rancangan acak kelompok (RAK) dengan rancangan 3 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan terdiri dari P0 (kontrol/pakan ternak:konsentrat = 60:40), P1: P0 (mengandung minyak kanola 4% dari total ransum); P2: P0 (mengandung mikroenkapsulasi minyak kanola 4% dari total ransum). Bahan pelapis yang digunakan dalam produk mikroenkapsulasi memiliki komposisi 50% maltodekstrin dan 50% gum arab. Data dianalisis menggunakan analisis sidik ragam. Hasil penelitian menunjukkan penambahan minyak kanola bebas maupun minyak kanola proteksi pada ransum sangat nyata (P<0,01) menurunkan populasi protozoa. Sintesis protein bakteri, NH3, retensi nitrogen, dan kadar BUN sangat nyata meningkat (P<0,01) pada pemberian minyak kanola bebas. Sementara penurunan terjadi pada pemberian minyak kanola terenkaspulasi dibandingkan kontrol. Namun, penambahan 4% minyak kanola bebas dan terenkapsulasi tidak signifikan mempengaruhi populasi bakteri total dan VFA. Dapat disimpulkan bahwa penambahan minyak kanola tanpa proteksi memberikan produksi NH3, BUN, dan SPM tertinggi di rumen serta minyak kanola dalam bentuk bebas dan terenkaspulasi mampu menurunkan pertumbuhan protozoa rumen yang merupakan predator bakteri tetapi tidak dapat menstimulasi pertumbuhan populasi bakteri rumen.Kata Kunci: mikroenkapsulasi, minyak kanola, rumen, spm, total bakteriABSTRACTThis experiment aimed to investigate the effects of unprotected and microencapsulated canola oil on rumen fermentation characteristics in Garut young rams. The design of experiment was using randomized block design (RBD) with 3 treatments and 5 groups as replication. The treatments were T0 (control/forage:concentrate = 60:40), T1 = T0 (Contain canola oil 4% total diet), T2 T0 (Contain microencapsulated canola oil (4% total diet). Coating materials composition used in microencapsulation were 50% maltodextrin and 50% arabic gum. The data were analyzed by using analysis of variance (ANOVA). The results showed that addition either protected or unprotected of canola oil on diet significantly (P<0.05) decreased rumen protozoa population. Microbial protein synthesis (MPS), NH3 nitrogen retention, and BUN were significantly (P<0.01) increased in unprotected canola oil meanwhile was decreased in the microencapsulated. Nonetheless, addition 4% of protected or unprotected canola oil did not significantly affect total bacterial population and VFA. It is concluded that addition of the unprotected canola oil gave the highest production of NH3, BUN, and MPS in rumen. In addition, the use of unprotected and microencapsulation of canola oil reduced the population of protozoa which are the predators of bacteria, but could not stimulate the growth population of rumen bacteria.Keywords: beef, diversification, development strategy, population

The objective of the study was to determine antioxidant enzyme activity and concentration of malondialdehyde on broiler which consumed feed containing lauric acid and natural antioxidant from Areca vestiaria Giseke. The study used 240 day-old chicks of Lohmann MB 202 P strain placed randomly at 24 experimental cage units (10 chickens each) of the litter system. The average temperature of the cage at the study was 25.80 to 32.080 C with relative air humidity rate of 67.69 to 86.20%. The research method followed a Factorial Completely Randomized Design 2 x 4 with 3 replications. The first factor was the source of lauric acid in feed, i.e. conventional coconut oil (CO) and pure lauric acid (LA). The second factor was the source of antioxidant in the form of dosage of Areca vestiaria (AV) and vitamin E supplementation (TF) with four levels of AV, ie 0, 625 mg.kg-1, 1250 mg.kg-1, and TF at a dose of 200 mg .kg-1 feed. Feed and drinking water were given ad libitum. Meat sampling to measure SOD, catalase and MDA was taken at the end of the study by first chickens were fasted for ± 8 hours (overnight). The sample used was right breast meat of experimental male chicken. The data were average from three experimental chickens. The data obtained were analyzed for the variant with the general linear model on MINITAB (version 16), then tested the differences between treatments using Tukey's honestly significant difference (HSD). The results showed that the source of laurate had a significant effect on SOD, catalase, and MDA, while antioxidant concentration significantly decreased SOD and MDA compared with control. The interaction between lauric sources and antioxidant concentrations affected catalase and MDA. The use of coconut oil as much as 3% and antioxidant supplementation of Areca vestiaria Giseke in feed at a dose of 1250 mg kg-1 could decrease lipid oxidation product of meat to produce a healthy food product.

The objective of this experiment was to examine the effect of protected lemuru fish oil on rumenmicrobes and its fermentation in buffalo and cattle fattened in feedlot. Six male buffaloes and eight malecattle aged between 1,5-2 years old with initial live weight of 218,66±16,28 kg and 217,37±15,44 kg,respectively, were used in this study. They were fattened in feedlot using 35% forage and 65% concentratediet for 2,5 months. The protected lemuru fish oil was in the form of dried carboxylate salt mixture (DCM)and given in the form of concentrate mixture, 45 g DCM/kg concentrate. The feeding treatments includedPO (forage+concentrate) dan P1 (forage+concentrate+DCM). At the end of feeding trial, the animals wereslaughtered and the rumen liquor were collected to analyze rumen microbes and its fermentation. Thedata were analyzed using a completely randomized design with 2x2 factorial models, feeding trial (PO and P1) as the first factor and animals as second factor (buffaloes and cattle). The results showed that nointeraction was found between the two factors on rumen pH, NH3 concentration, partial VFA, and rumenmicrobes. There were interaction effect of diets treatment and animal species on total VFA. Total VFAconcentration in buffaloes with DCM supplementation was significantly higher (P<0,05) than cattle withor without DCM supplementation. DCM supplementation decreased rumen pH and increased total VFA.The buffaloes had significantly higher total VFA, proteolitic bacteria, and butiric acid, but had lowerrumen pH and protozoa population compared to those of cattle. It is concluded that DCM supplementationcan increase the effectivity of protected fish oil concentration and proportion of VFA as well as rumenmicrobial population.

Putak is a local feed in west Timor, East Nusa Tenggara Province. It is obtained from soft core of palm tree which is called gebang tree (Corypha gebanga). Putak contains high carbohydrate and fiber but low in protein. As an effort to increase the ptotein level in putak a research was conducted by fermenting it with mixed-cultured of Trichoderma reesei and Aspergillus niger. A laboratorium experimental method was used and arranged factorially in Completely Randomized Design 3 x 4 x 3 namely three inoculant levels of T. reesei (T): 5,0; 7,5 and 10,0 % (w/w), and four levels of A. niger (A) 0,5; 1,0; 1,5 and 2,0% (w/w). Mixed-cultured was done by: first, T.reesei as treatment mix with putak and incubation for two days, after that mix with A.niger, incubation for two days. The best result of this study was on combination of T.reesei 7.5% level and 1,5% of A.niger were crude protein (23.62%) and soluble protein (14.92%) was highest and fiber 10,17%.

The objectives of the present study were to investigate the effect of dietary coconut oil as a source of lauric acid and Areca vestiaria Giseke (AV) as a natural antioxidant source on some haematological profile. Two hundred and forty (240) day-old unsexed Lohmann broiler chicks (MB-202 P) were divided into twenty four experimental units (ten chicks per unit) and arranged in a completely randomized design with a 2 x 4 factorial arrangement. Each experimental unit was repeated 3 times each with ten chicks. The first factor was the source of lauric acid in the ration consisted of 2 levels i.e., coconut oil and pure lauric acid. The second factor was dose of antioxidant consisted of 4 levels i.e., 0 (without antioxidant [AV and lauric acid] supplementation), AV at a dose of 625 mg kg-1 ration, AV at a dose of 1250 mg kg-1 ration, and tocopherol at a dose of 200 ppm). Blood sampling were collected from chicken at the end of experiment period (age 35 days). Total number of erythrocyte and leukocyte, Hb, PCV, together with absolute count of deferentiation of leukocyte were determined. General linear model and Tukey test were used for statistical analysis of the result. Blood sampling were collected from chicken at the end of experiment period (age 35 days). Total number of erythrocyte and leukocyte, Hb, PCV, together with absolute count of deferentiation of leukocyte were determined. General linear model and Tukey test were used for statistical analysis of the result. The study showed that source of lauric acid, antioxidant concentration and its interaction gave the same effect (P>0.05) to the erythrocytes, leucocytes, Hb, PCV, MCH, MCHC, and monocyte percentage of the broiler. The MCV in chickens consuming pure lauric acid was significantly higher than that of coconut oil. MCV values in chickens that received antioxidant AV at a dose of 625 mg kg-1 were significantly higher (P<0.05) than the others. The source of lauric acid was significant (P<0.01) affecting the percentage of lymphocytes and eosinophils, whereas the concentrations of antioxidants significantly affected the percentage of lymphocytes and heterophils, as well as the apparent effect (P<0.05) indicated by the eosinophil and basophil percentages.. The results of this study indicate that the use of lauric acid and concentration of antioxidant AV in the ration does not change the health status of broiler.
