The purpose of this experiment is to find out the effect of Aspergillus niger fermented tea waste (Camellia sinensis) in feed on body weight gain, protein efficiency and percentage of carcass of broiler. The experiment was conducted in a Completely Randomized Design using 100 day old chicks (DOC) Avian CP-707 strain. The animal were devided into five treatments of ration. Each treatment was replicated four times. All dietary treatment were formulated based on fermented tea-waste content, namely: RO (0.0%), R1 (2.5%), R2 (5.0%), R3 (7.5%), and R4 (10.0%). The results indicated that broilers gave the best responses to the R1 (2.5% fermented tea-waste) to all measured parameters. Positive responses also observed in broilers given ration containing fermented tea-waste up to the level 7.5%, however, at the level 10.0% decreased body weight gain, but the protein efficiency and the carcass percentage were equal to the R0 (control ration).

The main objective of this research was to obtain the effect of sheep serum (SS) and estrus sheep serum (ESS) on in vitro maturation oocyte and ovine fertilization. This study was carried out in experimental laboratory in animal reproduction laboratory, Faculty of Animal Husbandry, Padjadjaran University. Results showed that treatments significantly (P<0,05) influenced on maturation rate for germinal vesicle (GV), germinal vesicle breakdown (GVBD), metaphase-I (M-I) and metaphase-II (M-II), but no significantly (P>0.05) results observed on ovine in vitro fertilization (1, 2 and >2 pronuclei). Concentration of 10-20% ESS in CR1aa media were significantly (P<0,05) better than that of SS on maturation rate of ovine oocyte.

The objectives of research were to find out physico-chemical characters and to detect flavor volatile compound of kefir-like. Material used was skim milk TS 9.5% which was heated at 85oC for 30 minutes and cooled at 22oC before innoculation of the starter. Microorganisms used were (a) Lactobacillus acidophilus P155110, (b) Lactobacillus delbrueckii subsp. Bulgaricus NCIMB 11778, (c) Lactococcus lactis P155610, (d) Leuconostoc mesenteroides subsp. dextranicum NCIMB 3350, (e) Acetobacter aceti P154810, (f) Bifidobacterium longum BF1, and (g) Saccharomyces cerevisiae P156252. The treatments consist of P1 = without (b); P2 = without (a); and P3= used (a) until (g). The physico-chemical characters identified were lactic acid and lactose percentages, pH, viscosity, organoleptic test for intensity of kefir-like sensory attributes. Results indicated that B. longum was potential bacterium use for starter combination on kefir-like making. The use starter P1 combination has high acidity and viscosity, low pH and lactose percentage, and high intensity on attribute creamy-white color, soft and curdle consistency, and kefir specific aroma on kefir-like. Volatile compound acid group were dominate by high acidity character on kefir-like resulted from starter P1 combination. Compound of 3-hydroxi-2-butanone (acetoin) was affecting butter-like of P3 character. This compound resulted from which is a character of fermented milk flavor was not detected on P1 kefir-like.

Development of attractant for screwworm fly was required in myiasis control on livestock. The purpose of this study is to identify of volatile compounds from myiasis wound infested with Chrysomya bezziana larvae including to assess their responses in both cage and room assays. Both Friesian-Holstein heifer (FH) (animal 1) and Bali cattle (animal 2) were used as myiasis model. The artificial wounds (8-10 cm) were conducted on the rump of both animals and infested with about 200 eggs of C.bezziana. Odours from the infested wound were collected on day 1 and 3 for animal1 and day 3 and 5 for animal 2, post C. bezziana larvae infestation. Two different collection devices were used: firstly, absorption onto Tenax kept in steel tubes, whichwas attached to a collected bowl. The volatile organic compounds were collected from the wound and the surrounding animal hide by flowins the air through the inlet and outlet. Secondly, a solid phase micro extraction (SPME) device was inserted into bowl with passive (no air flow) odour collection. Gass chromatography/mass spectrometry was used to identify volatile compounds from wound. The compounds of the wound on animal 1, collected on day 1, produced only minor quantities of compounds (nonanal, decanal, hexanal and heptanal). Minor components such as DMDS and DMTS were only detected on day 3. The compounds of the wound on animal 2 was more varied and had a peculiar strike-like smell on day 3 and 5. They included indole, phenol, acetone, various sulfides (DMS, DMDS, DMTS), alcohols (butanol, 3-methylbutanol), aldehydes and acids. These compounds were selected and formulated into attractant (B92) then tested in both cage and room assays using SL-2 as control. Respond of flies was analyzed by ANOVA 5% (cage assay) and T test 5% (room assay). The result showed that the fly response to B92 was very low compared to SL-2 in cage assays (P<0.05). The addition of B92 to SL-2 could not increase the catch of flies in the cage assays (SL-2+B92=10:1; 10:3), there was no difference between SL-2 and B92/SL-2 in room assay, the fly response still low (P>0.05).

Local reovirus isolate is the virus which could be isolated from runting and stunting syndrome. The ability of local reovirus isolate to induce runting and stunting syndrome in broilers chicken was investigated. The day old chicks (doc) were infected with local reovirus isolate assessed clinically and pathologically at 1, 2 and 3 weeks post inoculation. A total of 40 DOC were divided into two groups. The first group (20 doc) was orally infected with ± 2 x 103 local reovirus isolate particle and the other used as negative control group. The results showed that the isolate caused wet droppings, stunting, enteritis, pancreatitis, malabsorbtion, bursal atrophy and spleenic hypertrophy, which similar to runting and stunting syndrome (RSS) disease in chicken. The body weight was reduced to 14.7% on the inoculated group at 4 weeks post inoculation. Key Words: Broiler, Local Reovirus Isolate, Runting and Stunting, Malabsorption

Organochlorine pesticide contamination in feed can cause residue in animal product (tissue and milk), so its become a problem in food safety. Solid phase extraction (SPE) has been carried out for determination organochlorine pesticide residues in food animal production. The technique was rapid, not costly and produce limited amount of hazardous-waste. Samples were homogenized with acetonitrile trough cartridge C18, eluted in fluorocyl column with 2% ether-petroleum or acetonitrile fortissue and milk samples respectively. The recoveries of tissue sample by addition lindane standard solution: 0.50 and 1.00 μg are 85.10 and 103.10% respectively, while that of milk with the addition of 0.50, 1.00 and 1.50 μg are 83.80, 88.69 and 91.24% respectively. Three replicates were carried out for every sample. According of validation criteria of FAO/IAEA the recovery for analysis of pesticide residues was 70-110%. Therefore, the method is applicable.
