This paper presents the resultsof an experimental attempt to improve thedrying kinetics for the retention of colourand sialic acid in edible bird’s nest throughheat pump drying. Kinetics of hot air dryingand heat pump drying were studied byperforming various drying trials on ediblebird’s nest. Isothermal drying trials wereconducted in hot air drying and heat pumpdrying at a temperature range of 40 °C-90 °C and 28.6 °C-40.6 °C, respectively.Intermittent drying trials were carried outin heat pump drying with two differentmodes, which are periodic air flow supplyand step-up air temperature. Experimentalresults showed that heat pump drying withlow temperature dehumidified air not onlyenhanced the drying kinetics but alsoproduced a stable final product of ediblebird’s nest. Heat pump-dried edible bird’ssamples retained a high concentration ofsialic acid when an appropriate dryingmode was selected.

There is increasing alarm and awareness about the health dangerposed by the arthropod vector causing Onchocerciasis. This study was carried out with the aim to throw more light on the prevalence of the arthropod vector, Simulun damnosum. This research enabled us toproffer preventive advice to government and citizens. In carrying out this study, villages around flowing waters were used as sample sites. The method applied was direct observation, coupled with efficientrecording. Atmospheric temperature readings were periodically taken along with the density of the insect population observed under such temperature. The same was done for relative humidity (%), solar radiation (gm-ca/cm2, lum) and luminescence (cd/m2) in relation to the insect population of available FMH at every given period (fly per man hour). Our findings showed that climate conditions influence the reproductive level and numbers of the vector. The wet season is most conducive for the arthropod vector to reproduce and multiply. The humidity is high and temperature seems to be at the average. It is during this period that greater preventive measures need to beintentionally heightened to subdue the dangerous activities of the vector.

The mycotoxin test data base (2005–2009) of the Veterinary PublicHealth Laboratory (VPHL), Department of Veterinary Services, Malaysia (DVS) showed that there was a significant increase (51%) of overall aflatoxin occurrences in various types of animal feed samples, especially those formulated from agricultural by-product, for the year 2008. A study was thus conducted to investigate if there could be some sources of mycotoxin contamination during theperiod of sample handling. Three different laboratory storage conditions were chosen for the study within a period of fourteendays i.e 4 °C, room temperature (in light) with mean relative humidity of 62.5%, and room temperature (in dark) with mean relative humidity of 55.7%. The observations showed that there were nosignificant differences in total aflatoxin, zearalenone, and fumonisin detections in all storage conditions as screened by the ELISA technique. However 11– 50% inconsistencies of the mycotoxinconcentrations detected were observed within the samples.

Exercise-induced changes of pro-oxidant generating substances and muscle fibre damaging enzymes are the possible causes of reduced performance in endurance horses. Therefore, this study aims to investigate on the performance of different age and gender using biochemical profile of endurance horses during 120 km endurance race. One hundred and eighty four Arabian endurance horses were physically examined and blood samples were collected post-race.&#xD;After physical examination, the MD (F, n= 44; G, n = 86) and SC (F, n = 20; G, n = 34) were identified. T-test and pairwise correlation were used for the analysis. There were significant differences in&#xD;CK, uric acid, lactate and age (P<0.0001) respectively between the gender in the MD and SC. There were significant differences in AST (P<0.0029) and GGT (P<0.0039) respectively between the gender in the&#xD;MD and SC. In conclusion age and gender significantly affect performance of endurance horses in relation to biochemical profile during 120 km endurance race. Therefore, further studies are required to determine if age, gender and biochemical profile could be used to assess performance in endurance horses.

Vancomycin-resistant enterococci (VRE) are well-known ascendant nosocomial pathogens. The recent detection of epidemiologic strain&#xD;carrying vanA gene in the community of people working with animals and in chickens has brought to the forefront the potential public health danger posed by these organism. The farm environment is a major source of VRE persistence in poultry farms. We carried out survival test to test the survival of the VRE isolates on dry condition and surface test to evaluate the inactivation of the isolates by in-use concentration of commonly used disinfectants. In the survival test, all isolates survived for at least 4 weeks in&#xD;colony counts of (1.00 × 103 – 3.86 × 103 CFU/ml) under clean condition and (1.00 × 103 – 2.02 × 104) for soiled condition.&#xD;Those that were suspended in 5% BSA solution to mimic organic matter load as obtainable on farms survived for at least 8 weeks at (1.54 × 102 – 1.34 × 103 CFU/ ml). In the surface test, inactivation of VRE isolates by in-use concentration of Lindores®, Omnicide® and Ecos Timsen® was tested using the European surface test (EST). All the tested disinfectants were active against the VRE isolates on both the standard test surface (stainless steel) and our test surface (wooden). The results shows microbiocidal effects (ME) for test disinfectants, i.e. the log10 CFU of micro-organisms compared between test biocide and control treated with distilled water, after 7 min of exposure as follows; Lindores® active on both surfaces 5.24 and 3.17, Ecos Timsen® active significantly on steel 4.90 than wood 2.98 and Omnicide® significantly less active on stainless steel&#xD;2.40 than on wood 3.50.

Quail closed-house system is a house that support quails’ optimumrequirements as far as temperature, relative humidity, ventilation and light are concerned. One of the four units of quail closed-house systems at the Institute of Poultry Technology, Malacca was used in this study. The objective of this project was to evaluate the performance of the quail closed-house system by comparing the condition of the house under current management condition and after the Standard Operating Procedure determined by DVS was adhered. Thehouse performance was evaluated by observing its ability to achieve an optimum temperature range of 20°C to 27°C with a relative humidity between 60% to 80% as perfect surroundings for quails. At the end of the experiments, the results showed a decline in internal temperature at almost 3°C and increasing in a relative humidity of 10% after all the specifications and procedures were followed.

A solar dryer was designed and constructed to dry fodder for livestock. The objectives of this project were to design and construct solar dryer systems for fodder drying and to evaluate the performance of the systems developed so that farmers can compare and choose an appropriate drying system to dry fodder. Two types of solar driers were designed in this study named as a) prototype solar dryer and b)greenhouse solar dryer. The performances of both systems were evaluated by observing their ability to achieve and maintain an optimum temperature of 60oC for a perfect drying process. In 2011, the prototype solar dryer was constructed at the Malaysia Veterinary Institute; however the results obtained were not as expected as the highest temperature achieved with the system was 44.9oC. Therefore, in 2012, the greenhouse solar dryer was constructed to replace the prototype model and the system has the ability to achieve the temperature up to 72.7oC.
