A study was conducted to evaluate the efficacy of piperazine dihydrochloride against natural infectionof Toxocara vitulorum in buffalo calves. In the first trial 60 based on fecal ascarid egg count and bodyweight naturally infected calves were, allocated into four groups. Three groups (groups B, C and D) weregiven piperazine dihydrochloride per os at dose levels of 200, 300 and 500 mg per kg body weight,respectivelythe remain group is non-treated controls. Piperazine treatment reduced egg excretion levels at98 to 99 per cent within 7, 14 and 21 days after treatment. Depite no significant differences were foundamong the three doses, highest egg count reductions were observed in calves given the drug 300 mg per kgbodyweight. The second trial were conducted using 10 additional calves. Piperazine significantly reducedT vitulorum egg excretion by 93% within 7 days post the treatment.

This study were conducted to determine the presence of toxocariosis in beef cattle in Kasiman Subdistrict, the Regency of Bojonegoro kept under the Sekolah Peternakan Rakyat (SPR) programme. The experiment were done to identify several risk factors that may play certain roles on the degree of prevalence and infection intensity. A total of 263 head of local beef cattle with various ages were taken for faecal samples and 80 farmers were interviewed. Results of the experiment indicated the prevalence of toxocariosis was 5.32% (CI 95% = 2.61-8.04%) influenced by age and gender which showed an effect on the risk of infection. The prevalence tends to decline by age group (p <0.001): calves under 6 months of age (23.68%), and between 6-12 months of age (7.41%), 1-2 years old calves (2.04%) and the above 2 years adults (1.34%). The prevalence is higher in the males group (12.7%) compared to the females group (3.0%), (p=0.003). Logistic regression analysis concluded that age was the only affecting variable to the rate of infection with mathematical models for toxocariosis. Logit toxocariosis = -0.058 -1.098 age.

This study aims to identify the diversity of flies that were caught and interacted with carcasses at the day and night. Each of the three rat carcasses (Rattus norvegicus) was placed outdoor and indoor within the campus of IPB Dramaga. The carcasses were put into a screen cage. Observation of flies was begun at 06:00 am and so on every four hours until the skeletal stage of the carcasses reached. The flies that come to the carcasses and into the screen cage were collected and identified. The decomposition of the indoor carcasses is slower than at outdoor, with the longer fresh stage. Meanwhile, post-decay stage and skeletal stage were achieved at the same time at each location. Nine spesies captured flies which are forensic indicator were Chrysomya megacephala (Fabricius), Chrysomya bezziana Villeneuve, Chrysomya rufifacies (Macquart), Chrysomya saffranea, Chrysomya spp, Lucilia spp, Sarcophaga spp, Calliphora spp and Musca domestica. C. bezziana Villeneuve and C. megacephala (Fabricius) were the dominant flies at outdoor carcasses. Meanwhile, the indoor carcasses was dominated by Lucilia spp.

Koksidiosis merupakan penyakit yang dapat menyerang berbagai jenis hewan termasuk kangguru. Informasi koksidiosis pada kangguru dahan kelabu masih sangat sedikit. Penelitian ini bertujuan untuk melakukan observasi kasus koksidiosis pada kanguru pohon kelabu yang meliputi pengamatan gejala klinis, dan mengidentifikasi jenis koksidia. Hasil observasi pada dua ekor kangguru pohon kelabu menunjukkan penurunan aktivitas, lemah, lesu dan nafsu makan menurun. Hasil pemeriksaan feses menunjukkan kedua hewan menderita koksidiosis dengan rata rata jumlah ookista tiap gram feses sebesar 450. Hasil identifikasi menunjukkan jenis koksidia yang menginfeksi adalah dari genus Eimeria spp.

Study on the chemical compound of painted nettle (Coleus blumei Benth) leave extract and its anthelmintic activity against chicken tapeworm were conducted. Leave of painted nettle were collected and extracted with hexane, chloroform, ethanol and water. Phytochemical analysis was carried out to determine the chemical compound of secondary metabolites. Anthelmintic activity was evaluated with an assay using chicken tapeworm in a serial microplate dilution method by determination of efective concentration 50 (EC50) using probit analysis. The result of phytochemistry analysis showed that Coleus leaves consisted of flavonoid, steroid, tannin and saponin. Three of four extracts displayed strong anthelmintic activity with the higest activity belong to chloroform extract with EC50 5 mg/ml followed by n-hexane 9 mg/ml and metanol extract 10,2 mg/ml, while water extract has a weak anthelmintic activity with 106,2 mg/ml. In general, chloroform extract proved to be a more efficient extractant of biologically active compounds than either hexane, ethanol or water extract. The promising activity displayed by a number of extracts has led to further investigation of the active compound. Unfortunately, the result of invivo assay showed that the chloroform extract treatment with dose level 25 mg/kg BW could not to reduce the number of tapeworm in chicken. It is interesting for further investigate the differences of respon between in vitro and in vivo to determine involved factors.
