Biogas plant is an anaerobic digester that produces biogas fromorganic materials. The general purpose of implementing biogas plant in an animal farm is to obtain biogas from animal manure and the effluent of biogas digester after fermentation process can be used as organic fertiliser. There are 15 biogas plants based on livestock waste that have been developed throughout Malaysia until 2018. Two more biogas plants are planned to be built in Segamat and Keningau. All biogas plants built were originally aimed for domestic use which is as source of energyused for cooking and incinerator as well as to generate electricity for farm use. Out of 15 biogas plants, 7 plants were built on cattle farms, 4 plants on pig farms, 3 plantson poultry farms and only 1 plant on buffalo farm. Total construction cost for each biogas plant is between MYR4,500 to MYR30 million. Based on the survey conducted, it revealed that only 40% of the plants are still functional. However, 60% were dormant or nonfunctional due to poor maintenance, design errors, lack of technical knowledge to run the system consistently, improper planning and monitoring or insufficient livestock waste to continuously producing biogas.

Salmonella stained antigen has been widely used in Malaysia for detection of Salmonella infection in poultry. Growth phase of four Salmonella enterica serovar Pullorum (SP 9-25, SP 14/11, SP 690/79 and SP 7107/07) used in the antigen production were investigated based on colony enumeration and turbidity. This study aimed to determine the growth curve and the difference between S. Pullorum isolates based on turbidity measurement and spread plate technique for optimisation towards biomass production of salmonella antigen using bioreactor. Current production of the antigen used conventional methods and the number of bacterial cells is low and with several other drawbacks. The isolates were cultured in nutrient broth, incubated aerobically with constant shake for 48 hours to determine the lag, exponential, stationary and the death phase of the bacteria. Turbidity of the bacterial cells was measured using spectrophotometer and the colony was counted using total plate count every four hours. Based on the colony forming unit per milliliter, SP 690/79 strain showed the fastest growth where this bacteria achieved its mid-exponential growth at 8 hours. This is followed by SP 14/11 where this strain demonstrated the mid-exponential growth at 12 hours. The other two strains (SP 9-25 and SP 7107-07) are the slowest growth where their mid-exponential growth was measured at 14 hours. However, SP 690/79also the fastest strain entering the death phase which demonstrates the difference growth of the S. Pullorum strains. This study demonstrates that each S. Pullorum strains multiplying and dying at different phase though in the same serovar.

The livestock industry has been relying merely on chemically synthesised antibiotic for eye infections as sprays and ointment. A natural remedy from Curcuma spp. has been tested for efficacy in curing keratoconjunctivitis and uveitis. A severe case of uveitis was cured within 7 days, with impaired vision restored. These results were observations of a preliminary study conducted in a goat with uveitis.

Ginger, about one year old domestic shorthaired cat with paresis was reported with constipation. Enema and laxatives prior to presentation was not effective. On palpation of the abdomen, a long tubular mass was palpated in the left caudal abdomen. Radiographic diagnosis of the megacolon was made and a subtotal colectomy was planned for the cat. A ventral mid-line celiotomy was made to explore the abdomen. Exploration revealed ascending, transverse and descending colon including the caecum found to be markedly distended due to faecal stasis. Following standard technique, a subtotal colectomy was performed. The cat recovered well after surgery without any complication. The owner reported that Ginger was doing well but died about seven months after surgery. Carcass was not available for necropsy. By clinical examination, diagnostic investigation and surgical exploration, other causes of megacolon were ruled out. The cat was about one year old with a short duration of illness. Without a definite history and by ruling out other causes, neurologic trauma was attributed as the probable cause of constipation and megacolon in the present case.

This case report describes paramphistomosis from the rumen ofan infected 3-year-old Bos indicus or also known as Zebu cattle that was sent to the Veterinary Research Institute (VRI), Ipoh,Perak for post-mortem examination with a history of a sudden death. On post-mortem, it was found that the rumen contents hada large number of pink, pear shaped flukes, which measured about 1 cm in length attached to the rumen wall. On performing the sedimentation technique on the rumen contents, operculated eggs with germ cells were observed microscopically under compound microscope with a magnification of 100×. Regular screening of cattle for flukes is an important part of parasite controlprogrammes especially in endemic areas as it can cause anaemia and deterioration in body condition.

The local river terrapins (Batagur affinis) are an important aspect of the river ecosystem. The Turtle Conservation Centre in Bota Kanan noted morbidity and mortality in its terrapin population and some were sent for full laboratory investigationto diagnose cause of death. The faecal samples were subjected to faecal floatation technique whereby ascarid eggs were observed indicating that the turtles had helminth infection. Ascarid eggs had thick walls and measured at 140.6 μm to 149.7 μm in diameter. Apart from this, post-mortem examination of intestinal contents also showed presence of nematodes identified as Oesophagostomum sp. Treatment and control have to be instituted to prevent further morbidity and losses.

In the Malaysian environment horses are primarily used in sports activities such as racing, endurance, dressage and show jumping as well as in recreational pursuits and police work. Recently, the Perak Turf Club witnessed the death of a four-yearold thoroughbred mare which was given enrofloxacin injection as treatment and was regularly dewormed and vaccinated againstequine influenza, Japanese encephalitis and tetanus. Post-mortem examination of intestinal contents revealed presence of worms. The sample was then sent to the Veterinary Research Institute (VRI), Perak for morphological identification of the worm. The worm was identified as Parascaris equorum. Thus, awareness ongastrointestinal parasites should be raised especially by recommending improved management practices such as proper manure disposal and deworming procedures to control parasite infestations as well as good management and nutrition.

Parasitic nematode infection in animal is one of the main causes for the mortality of animals and most of the treatment relies on the use of the anthelmintic drugs to overcome such a problem. However, the heavy use of anthelmintic contributed to the problem of multidrug resistance. This study was carried out to investigate the infectiveness of Punica granatum (aqueous leaf and peel extracts) as an alternative treatment. This study utilised the in-vitro assay technique (motility assayand larval migration inhibition assay) to determine the effect of the extracts on the survival of L3 stage of parasitic nematodes.The results showed that incubation of L3 in different concentrations (5, 10, 20, 50 and 100 mg/ml) of extracts paralysed and killed the worms after 24 hours and 48 hours ofincubation periods. The same results were obtained from larval migration inhibition assay, showing that both extracts of Punicagranatum inhibited the migration of the L3. After 2 hours of incubation in the leaf extract (5 mg/ml), the migration of nematode larvae was inhibited to 56±12.29% as compared tothe control. While for the peel extract the percentage of migration was reduced to 53 ±3.33%. Further reduction of the migration was observed at 10, 20 and 50 mg/ml of leaf extract.

In Malaysia, helminthiasis due to strongyles such as Haemonchuscontortus and coccidiosis caused by Eimeria sp. have been reported to cause severe economic losses in small ruminants livestock industry. This paper reports the occurrence of gastrointestinal parasite infections on small ruminants situated in Seberang Perai Selatan district, Penang. Faecal samples were obtained from a total of 193 animals,randomly selected from 14 ruminant farms. The results of this survey indicates that helminthiasis and coccidiosis is rampant insheep and goat farms. The most common infections diagnosed were helminthiasis (77.72%) and coccidiosis (60.10%) followedby Moniezia sp. (5.18%). From this study, it shows that parasitic diseases can be managed by good animal husbandryin farms since high parasitic infections were observed in farms that were poorly managed based on nutrition, hygiene andbasic animal husbandry practices. The smallholders depended on health and extension services from the State Veterinary Department. A continuous monitoring of small ruminant farms by the Department of Veterinary Services will provide important information for assisting farmers with managing the spread of parasitic infections and maintaining the productivity of animals.

Forty-nine fresh goat’s milk samples produced by local farmers and sold in market for public consumption as well as raw goat milk in Johor, Malaysia were analysed for total plate count(TPC) , E. coli, Coliform, Brucella melitensis, Brucella abortus,Coxiella burnetii as well as aflatoxin M1 (AFM1) content, as measures for food safety. The mean counts per ml for TPC were 4.90 x 105, 6.50 x 105, 1.60 x 105 and 1.48 x 106 for pasteurised, unpasteurised and unknown (status of pasteurisation) milk sold in the market as well as the raw milk from milkcollection center (MCC), respectively. Among pasteurised samples, only one had TPC count higher than the permitted level whereas the rest were all within the permitted level. The mean counts per ml for E. coli were <1.00 x 102 for pasteurised and unknown milkwhereas 1.67 x 101 for unpasteurised and 1.18 x 102 for raw milk. The mean counts per ml for coliform were 9.53 x 103, 9.76 x103, 1.20 x 102 and 1.16 x 104 for pasteurised, unpasteurised, unknown milk and raw milk, respectively. Overall, no significantdifferences on the bacterial counts in both pasteurised and unpasteurised milk. All milk samples were negative of B. melitensis and B. abortus, but one unknown sample fromthe market and two raw samples from MCC were positive of C. burnetii through the ELISA test. The unknown sample from the market showed the presence of C. burnetii when further analysed microscopically. Meanwhile, no sample exceeded the permitted level of AFM1 in milk.
