Abstract

This study aim was to evaluate quality of anaesthesia by using gravimetric infusion anaesthesia withketamine and propofol in dogs. The quality of anaesthesia, duration of actions, and the physiological responsseof anaesthesia were evaluated in twenty domestic dogs. Anaesthesia was induced intramuscularly withatropine (0.03 mg/kg)-xylazine (2 mg/kg) (AX), intravenously ketamine-propofol (KP) (4 mg/kg), andmaintained with continuous intravenous infusion with pre-mixed propofol (P) and normal saline containing2 mg/ml of propofol and 2 mg/ml of ketamine (K). Domestic stray dogs were randomly divided into fivegroups. Groups AXKP-K2P2, AXKP-K4P4, and AXKP-K6P6 were treated with ketamine-propofol the dose0.2 mg/kg/minute, 0.4 and 0.6 mg/kg/minute respectively, while group AXKP-P4 was given propofol 0.4 mg/kg/minute and group AXKP-I was given isoflurane 1-2%. Heart rate (HR), respiratory rate (RR),electrocardiogram (ECG), blood oxygen saturation (SpO2), end tidal CO2 (ET CO2), and capillary refill time(CRT) were measured. No significant difference (P>0.05) found between the groups in anaesthetion times.All groups showed rapid and smooth inductions, prolonged surgical stage, and rapid recovery. Groups AXKPK2P2and AXKP-K4P4 showed minimal physiological effect on the dogs. The HR, RR, ET CO2, SpO2, CRT,and ECG wave were stabl. Combination of AXKP-K6P6 induced SpO2 depression, increased and instabilityof HR, RR and ET CO2. Groups AXKP-P4 showed decreased of HR and respiratory depression. All anaestheticcombinations showed no significant influence (P>0.05) on the electricity of the dog’s heart. The combinationof ketamine-propofol at dose 0.2 and 0.4 mg/kg/minute were found to be better as an application formaintaining anaesthesia by gravimetric continuous intravenous infusion. The method is a suitablealternative for inhalation anaesthesia in dogs.

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 To monitor zinc and cortisone level, blood samples were withdrawn from each animalevery two weeks starting at age of pregnancy 3 months up to two months post parturition, in addition, tomonitor the cortisone level blood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

Friction affects the efficiency of a mechanical system. This paper discusses the influence of Tungsten Disulphide (WS2) as a friction modifier (FM). Friction and wear characteristics of base oil as a result of the addition of 0.1% and 0.5 % weight of WS2 were studied. WS2 nanoparticles were mixed with base oil using magnetic stirrer at 50oC for 60 minutes, then were homogenized in an ultrasonic homogenizer for 1 hour. Friction and wear characteristic of these mixtures were tested using four-ball and HFRR test-rig. The results show that the addition of both 0.1% and 0.5% WS2 nanoparticles increased by around 40% the anti-wear characteristic of mineral base oil group I and 12% for other groups of base oils. The increase in friction coefficients was in a range of 7.5% to 35% as a result of the addition of additives.

Abstract

The objective of this study is to develop a lubricant formula for the gasoline engine that has been converted to compressed natural gas (CNG-fueled). The lubricant specification is SAE 15W40 API SL. This study was conducted in six stages, namely; i). lubricant formulation, ii). laboratory scale production, iii). Laboratory analysis, iv). pilot scale production and laboratory analysis, v). test performance through bench test or a road test, vi). final data analysis and evaluation. A laboratory test of physical and chemical properties of lubricants refers to the Indonesian National Standard (SNI), followed by road tests up to the mileage of 10,000 kilometers. The result showed that the lubricant formula obtained can work well to 10,000 kilometers.

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.
