Primordial germ cells (PGCs) are original cells of spermatogonia in the testes or oogonia in the ovary. PGCs in poultry can be harvested and stored in the liquid nitrogen and can be used for conservation as genetic materials of poultry. The objective of this study was to obtain the optimal rate of temperature reduction on PGCs quality from three different Indonesian native chicken after thawing. Fertile eggs obtained from native chicken were incubated for 56 hours to obtain embryo at stage of 14-16. PGCs were isolated from the blood using modified Nycodenz Gradient Centrifugation technique. There after they were kept in a straw and equilibrated for 15 minutes at 5oC and frozen at the rate of temperature reduction of 0.3, 0.5, and 1oC per minute using embryo freezing machine (FHK Fujihara: ET-1). After the temperature reached -30oC, then they were plunged directly into the liquid nitrogen. Recovery rate and viability of PGCs after freezing and thawing were measured. The results of this study showed that the average recovery rate of PGCs that have been frozen at rate of temperature reduction of 1, 0.5, and 0.3oC per minute were 35.6, 43.9, and 44.9% respectively. However the rate of temperature reduction of 0.5 and 0.3oC per minute did not significantly affect the recovery rate. The average percentage of viability of PGCs that were frozen at the rate of 1, 0.5 and 0.3oC per minute were respectively 62.6, 77.5, and 77.4%. It seems that the viability followed the trend of recovery rates where the 1oC per minute reduction was the lowest quality compared to the other two treatments. It is concluded that the reduction of 0.5 or 0.3oC per minute are considered as the ideal temperature reduction when native chicken PGCs are frozen. Key Words: PGCs, Native Chicken, Conservation

The microorganism used as probiotics must be bio-safety, could be cheaply and easily produced, and suitable with the environment of the digestive track. Isolation was carried out from commercial culture (containing mixture of Bacillus spp.), digestive tract (proventriculus, small intestine and large intestine) of local and broiler chickens, and commercial yoghurts (fermented milk). Neutral and acidic nutrient agars (NA) were used as the media at room temperature and in the aerobic or anaerobic conditions. Separate colonies were isolated, stained with Gram and spore staining and observed under the microscope. The bacteria which were Gram positive bacillus and can form spores were further identified. Eight different species of Bacillus spp.: B. laterosporus, B. coagulans, B. alvei, B. circulans, B. brevis B. bodius, B. pasteurii, and B. macrolides were isolated from the commercial mixture. From the digestive tracts of local and broiler chickens, 13 bacteria and 2 yeasts were isolated, while 5 yeast were obtained from two commercial yoghurts. Those bacteria were facultative aerobic and only grew in neutral condition and not in acidic condition (pH 4.5), while the yeast were either facultative anaerobic also can grow in pH neutral and 4.5. The ability of each isolates to grow in the media containing mixture of minerals and glucose, sucrose or molasses were evaluated. Incubation was carried out in the shaker incubator at 40° C, 150 rpm for 48 hours. Dry matter of the biomass was determined as the growth parameter. All isolates of bacteria and yeast can grow in the substrate containing glucose, sucrose and molasses. Variance analyses show that there were interactions between kind of bacteria and carbon source or between kind of yeast and carbon source (P<0.05). Three isolates of bacteria that had highest production of biomass were B. coagulans on sucrose (the third for molasses), Sp. 9 on glucose, and B. apiaries on sucrose (the sixth on molasses). B. apiaries isolated from digestive tract of local chicken will be useful to be developed as probiotics. The highest production of yeast was the control Saccharomyces cerevisiae on three sugars. Between the isolates from digestive tract of local chicken, Toluraspora delbrueckii AL-15 produced 13.8x10-1 mg/ml biomassa on molasses.

The objectives of this research were to study Newcastle Disease Virus (NDV) infection in Subang area and to examine the diversity of the circulating NDV. Swabs of cloacal and oropharynx, and serum were sampled from total of 393 chickens and 149 ducks in backyard farms and live bird markets located in 10 subdistricts. Screening of NDV in pool of 5-7 samples by real-time Reverse-Transcription Polymerase Chain Reaction (rRT-PCR) matrix (M) showed 19/67 (28.3%) cloacal and 8/67 (11.9%) pharyngeal pools of chicken samples; 18/67 (26.9%) of the pools excreted virus via cloaca and oropharynx, while the duck pools of 8/30 (26.7%) shed virus from cloaca. Virus isolation attempted on individual sample from positive pools yielded 18 isolates which the majority of the isolates showed homogeneous antigenic character, only some of these showed variations up to 2 Log2 with Lasota and 4 Log2 with Komarov antisera. Majority of isolates had a higher affinity to Komarov indicating their propencity to virulent strains. Pathogenicity examination using elution test showed 3 isolates virus were grouped to mesogenic strains and 15 isolates to velogenic strain, in agreement with rRT-PCR fusion results. HI test on 408 sera showed that NDV antibody was detected in 48 (12%) birds with titres ranging from 1 to 8 Log2; only about 13% of vaccinated chickens demonstrated protective antibody titre (≥3 Log2). Newcastle disease is still endemic in Subang with relatively low antigenic variation among circulating strains.

Publisher : Indonesian Center for Animal Research and Development (ICARD)

The effect of artificial dehydration on snail Lymnaea rubiginosa was investigated in the laboratory by monitoring its survival and development, because as aquatic organism, this snail must be able to adapt or tolerate with the changes in its habitat. Fifty laboratory-reared L. rubiginosa with shell length between 1.0-1.5 cm (adult) were placed in each sloping earth aquarium (60x80x20 cm) which were already filled with water about 15 cm depth. Five aquaria were used in this study, and one week after being established the water from 4 aquaria was drained while one aquarium was retained with water as a control. The water was replaced in one of dehydrated aquarium each week for four weeks, commencing one week after draining the water. The survival of snails in each aquarium were recorded every two days over a period of 3 months. The results indicated that the mortality rate of adult snails increased as the period of dehydration increased. After four week dehydration only 16% of adult snails survive compared to 68% survival in the control aquarium, and dehydration for 4 weeks prolonged the hatching time of eggs. Moreover, in dehydrated aquaria, the egg masses were deposited in a random pattern on the surface of the soil, whereas in the control aquarium they were laid on the soil-water junction. Key words : Dehydration, Lymnaea rubiginosa, survival, fasciolosis

Previous studies shown that Indonesian Thin Tailed (ITT) sheep are more resistant to Fasciola gigantica infection than Merino sheep. This difference could be mediated by intrinsic defense enzymes of the parasite. Certain enzymes are known to be crucial in parasite survival against host-derived immune responses. We measured some of them to identify if any comparative differences between the enzyme activities of the parasites from the two hosts (ITT & Merino sheep) could account for the mechanisms of parasite resistance to killing by the Merino host and susceptibility to killing by the ITT host. Parasites were extracted from the liver of infected ITT and Merino sheep and superoxide dismutase (SOD), glutathione S-transferase (GST) and catalase (CAT) enzyme activities were assayed. SOD and GST levels were found to be higher in parasites isolated from Merino than those of ITT sheep (P<0.05), CAT activity was not detected in any of the parasites. There was significantly higher eosinophils (P<0,05) in the ITT sheep peritoneal cells. These results suggested that SOD dan GST are important molecules in determining susceptibility in Fasciola-infected Merino sheep and resistance in Fasciola-infected ITT sheep.

Studies regarding the use of living microorganisms as supplement have been done in the last two decades to improve digestion process in the rumen. Many factors affect the use of the supplement, such as ration composition and physiological status of the animals. Materials used in this experiment are Aspergillus oryzae (AO) derived from ‘tauco’ (salty fermented soybean) and soybean sauce processing factories located in Bogor, Cianjur, and Sukabumi districts (15 sources), and also AO culture collections of the Indonesian Res. Inst. for Anim. Prod. (2 strains) and one strain from Indonesian Res. Inst. for Vet. Sci. in Bogor. The fungus was first isolated in potato dextrose agar (PDA), incubated at room temp. (26-300C) for 5 days for purification. The AO from PDA then inoculated into cooked rice enriched with mineral mix, oven-dried (40-450C), then ground and kept in refrigerator as a stock culture for further use. To produce more AO (scaling-up), the culture is inoculated in two basal media, i.e. soybean meal and ‘onggok’ (tapioca processing waste) enriched with mineral mix, dried and ground, then kept in refrigerator as A. oryzae fermentation culture (AOFC). Ground-dried King grass was used for in vitro digestion trials using sheep rumen fluid, which was not supplemented (control) or supplemented with the AOFC (10% w/w) from various sources. Three best AOFC (by origin) were chosen and used for further digestion study. The study was run using 2 (media) x 3 (AOFC origin) factorial experiment based on a completely randomized design and Duncan’s MRT was applied to test differences among treatment means. Preliminary results indicated of the AOFC-SP66, -F172, and -CT4 used, the best AOFC was SP66, as it increased (P<0.05) fiber (NDF) digestion (10.5% better than the control). Total VFA productions were similar, but acetate content in the rumen fluid was lowered (P<0.05), while propionate and butyrate levels were alleviated (P<0.05) by the AOFC-SP66. Ammonia content was not affected by addition of AOFC. No differences were detected on digestion parameters between the two media used for AO cultivation, therefore, it is suggested to use ‘onggok’ for producing AOFC in large scale. VFAs composition pattern suggests that AOFC was more suitably used for meat rather than for milk production. Key words: Fungus, King grass, digestibility, rumen fluid

Eighteen local sheep weighing approximately 15 kg were randomly divided into 3 treatment groups . All animals received a mixture of elephant and native grasses (50 :50) ad libitum + concentrate (0.5% of liveweight) . The treatments given were : (1) no additive, (II) addition of placebo and (III) addition of methanol-extracted Sapindus rarak fruit (MES) at level of 0.07% of liveweight. Placebo and MES were given orally every 3 days . Feeding treatments were conducted for 14 weeks . Rumen liquor of all animals were collected in the third week "and observed for rumen ecosystem and ruminal digestibility . Bodyweight gain and feed consumption were measured . The results showed that MES eliminates the protozoal population by 57% and sequently increases bacterial population by 69% when compared to control (1). Lowered protozoa population has no effect on lactic acid and total volatile fatty acids productions, and a consequence, does not change pH (Pa0.05) . However, lowered protozoa population decreased NH3-N content (P<0 .05) . Cumulative gas production resulting from substrate (rice straw) fermented by rumen liquor from sheep fed MES-added diet (III) increased by 13% when compared to control (1)). Compared to control (I), average daily gain of sheep fed MES-added diet (111) is increased by 44% with an improved efficiency by 28%. Keywords : Saponin, protozoa, bacteria, performance of sheep

Effect of slow-release urea on efficiency of rumen microbial protein synthesis (EMPS) was examined using an in vitro technique. The objective of this experiment was to reveal the in vitro slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea in relation to EMPS observed in different incubation time. The experimental design employed was randomized block design with 4 x 3 factorial plus a control treatment, and conducted in two replications. Factors were various urea sources (urea, zinc-urea, zeolites-urea, and zeolites-zinc-urea) and molasses concentrations (0%, 6%, and 12%) in rice straw-based diets. The control treatment was the rice straw-based diets containing neither urea nor molasses. Diets consisting of 45% rice straw and 55% concentrates (DM basis) were formulated to have similar N and TDN levels. Responses of parameters measured were subjected to MANOVA using the GLM procedure of SPSS 16.00 and differences among mean values, if applicable, were examined using HSD-test. Orthogonal comparisons were used to determine the effects of the control treatment vs. various urea sources. Results indicated that treatment of UZ combined with 6% of molasses showed the highest microbial biomass production (2.71 mg/l) at 24 hours fermentation period with its peak production estimation (3.2 mg/l) reached at 33.5 hours of fermentation period. Moreover, UZ treatment resulted in the highest microbial protein synthesis (1,381.45 ± 77.1 mg/l) at 24 hours fermentation period with its peak microbial protein synthesis estimation (1,756.04 mg/l) reached at 33.7 hours of fermentation period. The highest EMPS (25.98 ± 1.21 mg/100 mg OMD) was achieved when ration contained 6% of molasses. Key words: Slow-Release Urea, Microbial Protein Synthesis, Microbial Biomass, In vitro

The study was conducted to detect antigen H5N1 of highly pathogenic Avian Influenza (HPAI) virus in various farms in East and West Java. The immunohistochemical technique was applied due to Hematoxilin-eosin (H&E) staining was impossible to visualize the antigen in tissue. Immunohistochemical staining was applied for some visceral organs collected from the areas where the outbreaks occurred in September-October 2003. The specimens were processed as histopathological paraffin blocks using standard method. The blocks that were suspected to have antigen H5N1 were cut and rabbit antisera to H5N1 produced from the local isolate was applied as the primary antibody. Biotinylated secondary antibody and avidin biotin peroxidase from a commercial kit were administered. The antigen present in the tissues were visualized by adding a substrate called Amino Ethyl Carbazole (AEC) resulting in reddish brown colour. This immunostaining proved to be accurate and reliably quick method to detect H5N1 antigen present in the avian tissues. In conclusion, the outbreak of bird flu was caused by H5N1 strain and the antigen could be found in wattles, combs, brain, trachea, lungs, heart, proventriculus, liver, spleen, kidney and ovary.

The immune responses of cattle and buffaloes against the infection of liver flukes Fasciola gigantica were observed by ELISA. Six cattle and 6 buffaloes were infected orally with 700 metacercariae of F. gigantica, 2 cattle and 2 buffaloes were remained uninfected as control animals. Serum blood samples were collected weekly and the antibody levels were monitored before and after treatment. The results showed that the antibody level on cattle increased after 2 weeks post-infection, then gradually increased until reaching the peak at II weeks after infection. In the contrary, the antibody level on buffaloes appeared slower than on cattle, it increased after 13 weeks of infection and reach the peak at 25 weeks after infection. When the antibodylevels reach the peak, both groups of infected animals were treated with triclabendazole. After treatment, the antibody level oncattle was immediately decreased at one week of treatment, and gradually decreased up to the lowest antibody level at 7 weeks after treatment. The response of the treatment on buffaloes showed almost similar pattern, the antibody level decreased after one week of treatment, then remained constant for about 4 weeks, and reach the lowest antibody level at 7 weeks after treatment. It is concluded that the immune responses against the infection of F. gigantica in cattle and buffaloes are different, but the response of the treatment with triclabendazole are similar. Key words: Fasciola gigantica, cattle, buffaloes, antibody levels, triclabendazole
