A total of 3430 serum samples from various animal species and humans were tested using microscopic agglutination test (MAT) to determine
the frequency of the important leptospiral serovars involved in animals and humans. The sera were screened against 14 serovars of pathogenic Leptospira interogans and 1 serovar of non-pathogenic Leptospira biflexa. Altogether, 441 (12.86%) of the tested serum samples were found to be positive serologically. Tested sera reacted to all 15 serovars used in this study. The most predominant serovar in cattle and sheep is hardjo (39.60% and 66.67%). However, in goat, buffalo and horse, the most frequent serovar detected is hebdomadis (30.00%, 32.58% and 57.14%). In dog, the most predominant serovar is bataviae (19.23%). In humans, the most predominant serovar is cynopteri (3.26%). Among all the samples tested, there were no positive samples from pig and cat. Domestic animals, rodents and
pets can infect the environment or transmit the disease to human or other animals. This study showed that domestic animals could play a role in the epidemiology of leptospirosis and represents a threat to
public health.

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.

Four types of products made from Neem namely, neem leaf decoction, neem capsule, neem fresh juice and neem extract were given to 4 groups of goat for a period of 10 weeks to evaluate the effectiveness of these products in controlling natural gastrointestinal helminth infection. During the course of the study, faecal egg counts, Packed Cell Volume and FAMACHA readings were&#xD;monitored weekly. Results of feeding these products were variable when compared to untreated control animals, however, a 40-60% worm control was observed. Further testing is required to fine tune these&#xD;products for use in the field especially where anthelmintic resistance deems drugs to be ineffective.

The objective of this study was to determine the seroprevalence of dourine from imported horses using Complement Fixation Test. Dourine is classified as a OIE listed B disease (OIE Terrestrial Manual 2008) where equines are mainly susceptible to it and it had occurred in many countries such as Africa, the Middle East, South America and South-eastern Europe. Malaysia regularly imports Australian horses for the equestrian sector which encompasses activities such as racing and endurance as well as other recreational or leisure activities in Malaysia. As such, awareness towards this disease is important during importation of horses to avoid dourine embark into Malaysia. A total of 288 horse sera samples obtained from animal quarantine stations and private stables were examined for dourine by complement fixation test. Results showed serologically negative results for dourine with all the samples tested.

A study was conducted to determine the prevalence of Newcastle disease (ND) and Avian Influenza (AI) from backyard chickens and ducks in Sabah. A total of 2,117 samples consisting of 1,498 swabs and 619 serum samples were taken from all districts in the state.&#xD;All samples tested were negative to Avian Influenza virus. 23.59% of the 619 serum samples collected were sero-positive for Newcastle Disease with the highest HI titre being 1/256. Only one pool of 4&#xD;trachael swabs or 0.27% of the total 1,498 swabs was positive on virus isolation for Newcastle Disease. No Avian influenza virus was isolated from all the samples collected.

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.

A total of 204 rodents comprising of 14 species were identified from four different habitats namely urban, forest, paddy field and coastal. The Gombak forest reserve habitat was found to be ideal&#xD;for the survival of 11 different rodent species. Maxomys rajah, Leopoldamys sabanus and Sundamys muelleri were the predominant rodent species distributed in the Gombak forest. Rattus ratus diardii was found mainly in the urban, paddy field and coastal habitat (67.1%). Morphological measurements of the rodents trapped from the four habitats did not show any major changes.

The rapid method for predicting palm kernel cake quality with near infrared reflectance spectroscopy was investigated. Chemical tests for moisture, ash, crude protein, crude fat, crude fibre, total digestible nutrients (TDN), nitrogen free extract (NFE), metabolisable energy (ME), calcium and phosphorous were time&#xD;consuming and involve high cost. This technology can save considerable time by testing all the parameters simultaneously;&#xD;however accurate calibration of the equipment is essential. Near infrared (NIR) partial least square (PLS) regression models for determination of several palm kernel cake quality parameters were&#xD;developed from NIRFlex Model N-500 (Buchi). In general, reliable prediction results were obtained for the TDN (SEP = 0.85 r2 = 0.99), NFE (SEP = 0.42 r2 = 0.97) and crude protein (SEP = 0.57 r2 = 0.98)&#xD;PLS regression models.
