Abstract

The objective at this experiment was to study the role of zinc supplementation (Zn) in minimizingstress at parturition. Thirty etawah cross breed age 3-6 years with average body weight 30-50 kg were usedin this study and divided into three groups ; i) animal were given grass + feed concentrate + ZnSO4 40 mg/kg dry matter ( control group) ; (ii) grass + feed concentrate + ZnSO4 60 mg/kg dry matter (treatment 1), and(iii) grass + feed concentrate + ZnSO4 80 mg/kg dry matter (treatment 2), respectively drinking water weregiven ad libitum. To monitor zinc and cortisone level, blood samples were withdrawn from each animalevery two weeks starting at age of pregnancy 3 months up to two months post parturition, in addition, tomonitor the cortisone level blood samples were also collected at 1,2,3 and 7 days post parturition. The Znand cortisone serum were analyzed using atomic absorbent spectro photometric (AAS) andradioimmunoassay (RIA), respectively the result showed that generally pregnancy at the beginning andget serum level at cortisone was relatively similar between the three animal groups and there was atendency to increase and reached peak at parts then gradually decrease until the and of the observation. Atparturition the lowest serum level at cortisone (19.00±18.72 mg/ml) was observed in animals receiving the60/ dry matter zinc supplement compared to animal receiving 80 mg/ dry matter zinc ( 52.65 ± 30.83 mg/ml) and control animal ( 75.92 ± 42.88 mg/ml). in addition serum level at Zn was significantly higher inanimal receiving 60 mg and 80 mg Zn in their diets compared to control animals. The best profiles wereseen in animal given 60 mg/kg dry matter Zn supplement. In conclusion, the addition of Zn in the diets hadsignificant effect in minimizing stress as pictured by the low serum level at cortisone at parturition.

Abstract

The research aimed to observe the occurrence of dermatophyte and other fungal species in grooming rooms and on groomers' clothing in several pet clinics and pet shops in Bogor City West Java. Ten veterinary clinics and five pet stores served as the study sites for this investigation. Five plates containing growth media were placed at five points in each room. Clothing swabs were collected from groomers immediately before they initiated their daily work activities. The result showed ten genus/species identified in grooming room and 16 genus/species isolated from the groomer clothes. Fusarium sp. was the predominant fungal isolate in grooming rooms (24.39%), followed by Candida albicans (9.76%). Notably, Fusarium sp. was also detected on groomers' clothing at a prevalence of 20.00%. Other pathogenic isolates included Aspergillus flavus and A. fumigatus. Despite the routine use of quaternary ammonium compounds, glutaraldehyde, anionic surfactants, and the ectoparasiticide amitraz in facility hygiene protocols, these disinfectant regimens insufficient in controlling fungal contamination. These findings highlight potential gaps in current disinfection practices within pet care facilities.

Abstract

Anjing jantan ras dachsund (Teckel) berwarna hitam, berusia 4 tahun dengan bobot badan 7,5 kg dibawa pemiliknya datang ke klinik hewan dengan keluhan muntah berulang. Hasil pemeriksaan hematologi menunjukkan polisitemia, leukositosis dan jumlah granulosit yang tinggi. Hasil uji biokimia darah menunjukkan peningkatan pada aktivitas SGPT/ALT, GAMA-GT, total bilirubin, total protein, albumin, rasio ALB/GLOB dan rasio BUN/CRE. Hasil radiografi menunjukkan adanya bentukan membulat radiolucent didekat organ hati. Diagnosa kasus klinis pada anjing ini yaitu extrahepatic biliary duct obstruction dan terapi simptomatik dilakukan dengan memberikan gastroprotektan, antiemetik, serta obat-obatan untuk membantu memperbaiki fungsi hati. Pengobatan dilakukan selama 2 minggu dan menunjukan perbaikan pada organ hati berdasarkan hasil pemeriksaan biokimia darah, diikuti dengan tidak ada dilatasi kantung empedu pada radiogram.

Abstract

Symmetry Dimethylarginine (SDMA) is an important biomarker for early diagnosis of kidney disease. Studies suggest that SDMA is a more sensitive indicator of kidney function compared to traditional markers such as blood urea nitrogen (BUN) and creatinine. Since 2015, the International Renal Interest Society (IRIS) has established SDMA as one of the indicators for diagnosis and determining the stage of chronic kidney disease (CKD) in dogs and cats. SDMA assay use in veterinary clinics in Indonesia has empirically become more common. The aim of this study was to identify scientific reports on SDMA assay use in the diagnosis of kidney disease in dogs and cats in Indonesia. We performed a literature search in the Garuda portal and Google Scholar using the following keywords: “SDMA” or “Symmetry Dimethylarginine”, “dogs”, “cats” and “Indonesia”. The search strategy utilized English and Bahasa Indonesia, and the results were screened for relevance to the topic, and limited to studies conducted in Indonesia. Seven scientific articles in national and international journals reported the use of SDMA assay in cases of kidney disease in dogs or cats in Indonesia, published between 2021-2023. It is expected that SDMA assay use will continue to increase in veterinary practice settings in the country, and it is therefore critical to have a proper understanding of the advantages and limitations of SDMA use for kidney disease diagnosis.

Abstract

This study aims to develop mathematical equations used in Wright’s method to predictkinematic viscosity of liquid-binary mixture consisting of base oil and additive. The equationis developed by addition of specific constants (αi and αc), representing interaction ofeach component in the mixtures. Evaluation is done using 70 empirical data from 35 samplesderived from liquid blending of 4 types of base oils (B.1, B.2, B.3 and B.4) and olefincopolymers (OCPs), varied in the range of 5-30 % of weight. Kinematic viscosity is measuredat 40oC and 100oC using a cannon automatic viscometer series 2000 (CAV 2000)according to ASTM method D 445. Validation of the equation (Developed-Wright’s method)is performed over all of liquid-binary mixtures of base oil-OCPs, and the accuracy isindicated by percent average absolute deviation (%AAD). The results show that the additionof specific constants could minimize the deviations of estimated values. The averagedeviation of Developed-Wright’s method on kinematic viscosity estimation at 40oC and100oC becomes 2.056 % and 1.917% respectively, lower than Wright’s method which are8.341 % and 14.696%; meanwhile the maximum deviation reaches 5.821 % and 4.657%,lower than Wright’s method which are 21.256 % and 25.265% respectively. These valuesindicate that the Developed-Wright’s method has better accuracy.

Abstract

Poor lubrication may cause wear on the surface moving parts of engine components such as bearings due to the metal-to-metal contact. Engine components utilized on the road-test of gasoline engine’s lubricating oil API SL showed wear and tear on some parts of them. The sum of wear occurred during the road test were varied. Therefore, an analysis of wear quantity of engine’s components was a necessity in order to get information about lubrication condition on engine. Analysis of wear was conducted by components’ rating based on the standard specifications set out for performance level of lubricant oil API SL and ILSAC GF-3 (SNI 06-7069-2005). Analysis based on Seq. IIIF showed that average value of the piston skirt varnish is 10, low temperature viscosity is 4673 cP, and cam wear lifter is 0.002 mm. It was also showed that the minimum kinematics viscosity increase was managed to be stay-in-grade. Analysis based on Seq. IVA showed that the average value of cam wear is 0.0015 mm. Analysis based on Seq. VII showed that the value of bearing weight loss was 0.010 g and there was no deposit at high temperatures. Shear stability analysis based on Seq. VIII showed that the viscosity of lubricant oil is still in the range of allowed values.
