A study was conducted to isolate and identify of lactic acid bacteria originated from gastric fluid of bali cattle, and to determine their potential as the candidates of biopreservative. Lactic acid bacteria were isolated by culturing the gastric fluid of bali cattle in de Mann, Rogosa, Sharpe (MRS) medium; screening the bacteria, and identification of bacteria species by Analytical Profile Index (API) 50 CHL Kit. The results showed that, the new species of lactic acid bacteria were isolated and identified as Lactococcus lactis spp lactis 1 (SR21 isolate) and Lactobacillus brevis 1 (SR54 isolate) that have broad spectrum antimicrobial activities. It is clear from this study that a potential lactic acid bacteria producing antimicrobial agent can be isolated from the gastric fluid of bali cattle.

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.

Penerapan Kultur Campuran Trichoderma reesei dan Aspergillus niger dalam Meningkatkan Kualitas Putak sebagai Pakan (APPLIED MIXED-CULTURED ASPERGILLUS NIGER AND TRICHODERMA REESEI TO INCREASE PUTAK QUALITY AS FEED) Maritje Aleonor Hilakore; Suryahadi Suryahadi; Komang Wiryawan; Djumali Mangunwijaya

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.

Mycotoxins are toxic metabolites produced by some fungal species commonly found in food and feed,particularly in cereals. In intensive production systems, dairy cattle are commonly fed with cereal-richdiets and, consequently, are more exposed to micotoxins. Besides, such diet is often associated with ahigher risk of rumen acidosis which can also affect the performance and the helath of animal. In addition,the efficacy of microbial detoxification can be reduced during acidosis. For instance, some authors observeda decrease in the number of protozoa that are responsible for the degradation of some mycotoxins. Anotherconsequence of acidosis is the potential modification of ruminal absorption of mycotoxins, which until nowhas received scarce attention. Yeast Saccharomyces cerevisiae, probiotic additives have been shown toreduce the post-feeding drop in rumen pH and to increase the number of ruminal protozoa. This effect canbe positive in reducing the absorption and toxicity of mycotoxins in ruminantia.
