This study was conducted to investigate the presence of foot-and-mouth disease virus (FMDV) in different geographic locations of Tanzania. Epithelial tissues and fluids (n = 364) were collected from cattle exhibiting oral and foot vesicular lesions suggestive of FMD and submitted for routine FMD diagnosis. The analysis of these samples collected during the period of 2002 and 2010 was performed by serotype-specific antigen capture ELISA to determine the presence of FMDV. The results of this study indicated that 167 out of 364 (46.1%) of the samples contained FMDV antigen. Of the 167 positive samples, 37 (28.4%) were type O, 7 (4.1%) type A, 45 (21.9%) SAT 1 and 79 (45.6%) SAT 2. Two FMDV serotypes (O and SAT 2) were widely distributed throughout Tanzania whilst SAT 1 and A types were only found in the Eastern zone. Our findings suggest that serotypes A, O, SAT 1 and SAT 2 prevail in Tanzania and are associated with the recent FMD outbreaks. The lack of comprehensive animal movement records and inconsistent vaccination programmes make it difficult to determine the exact source of FMD outbreaks or to trace the transmission of the disease over time. Therefore, further collection and analysis of samples from domestic and wild animals are being undertaken to investigate the genetic and antigenic characteristics of the circulating strains, so that a rational method to control FMD in Tanzania and the neighbouring countries can be recommended.

2012
Dautu, George(University of Zambia Department of Disease Control) | Sindato, Calvin(National Institute for Medical Research) | Mweene, Aaron S.(University of Zambia Department of Disease Control) | Samui, Kenny L.(University of Zambia Department of Disease Control) | Roy, Polly(London School of Hygiene and Tropical Medicine) | Noad, Robert(Royal Veterinary College) | Paweska, Janusz(National Institute for Communicable Diseases) | Majiwa, Phelix A.O.(Onderstepoort Veterinary Institute) | Musoke, Antony J.(Onderstepoort Veterinary Institute)
Rift Valley fever (RVF) in Zambia was first reported in 1974 during an epizootic of cattle and sheep that occurred in parts of Central, Southern and Copperbelt Provinces. In 1990, the disease was documented in nine districts of the provinces of Zambia. In the last two decades, there have been no reports of RVF. This long period without reported clinical disease raises questions as to whether RVF is a current or just a perceived threat. To address this question, World Organisation for Animal Health (OIE) disease occurrence data on RVF for the period 2005-2010 in the Southern Africa Development Community (SADC) was analysed. From the analysis, it was evident that most countries that share a common border with Zambia had reported at least one occurrence of the disease during the period under review. Due to the absence of natural physical barriers between Zambia and most of her neighbours, informal livestock trade and movements is a ubiquitous reality. Analysis of the rainfall patterns also showed that Zambia received rains sufficient to support a mosquito population large enough for high risk of RVF transmission. The evidence of disease occurrence in nearby countries coupled with animal movement, and environmental risk suggests that RVF is a serious threat to Zambia. In conclusion, the current occurrence of RVF in Zambia is unclear, but there are sufficient indications that the magnitude of the circulating infection is such that capacity building in disease surveillance and courses on recognition of the disease for field staff is recommended. Given the zoonotic potential of RVF, these measures are also a prerequisite for accurate assessment of the disease burden in humans.

2012
Chandrawathani P. | Nurul Aini R.
Parasitic helminth infections in small ruminants are prevalent in South East Asia (SEA), limiting productivity and causing major economic loss for farmers. The hot, wet, tropical climate all year
round favours trichostrongylid infections, predominantly haemonchosis in sheep and goats. Commercial large scale farms, with
more than 300 animals, as well as small holders or backyard farmers with less than 50 animals face the debilitating effects of haemonchosis when they graze their animals as effective worm control is often hampered by anthelmintic resistance. In Malaysia, frequent and indiscriminate use of anthelmintics in the past has resulted
in the majority of the small ruminant population facing resistance to one or more anthelmintics. Several alternative methods of worm control are being employed by farmers; the most important and effective being cut and carry or zero grazing, where the animals are kept in pens and grass is cut and fed. In Cambodia and Myanmar,
ruminants are still tethered or stall fed with minimal drug use. In Indonesia and Thailand, commercial goat and sheep farms are fast expanding to produce breeder stock for the SEA market. However, up to
75% of the small ruminant population is still traditionally managed by small scale farmers. In most of SEA, the McMaster method for faecal worm egg counts is the only diagnostic test used to assess helminthosis in ruminants. There is an urgent need to increase awareness and information on the need for testing faecal samples regularly before drenching, conducting faecal egg count reduction tests on a yearly basis, use of the FAMACHA technique to enable
selective treatment of individual animals. The use of alternative worm control methods to manage helminthosis will help promote effective ruminant production with reduced drug use and ncourage “green” farming methods. Extension of research on local bioactive plants which may have the potential to control helminthosis may also be beneficial in the longer term.

2012
Wan Zaharil M. | Shanmugavelu S. | Wong, H. K. | Mardhati M.
A beef feedlot production decision support system (DSS) was developed based on Microsoft® Excel. The DSS comprises of three modules i) an ingredient database ii) a least-cost ration formulation module and iii) beef growth simulation module. The program uses empirical equations developed for tropical beef to simulate nutrient requirements and daily body weight gains based on the formulated feed ration. The formulated least cost ration can be pasted automatically into the growth model to evaluate performance and economic viability. The growth model calculates nutrient available and computes body weight gain on a daily basis, summates weight gain and stops at the targeted body weight. The data output include i) days to reach target body weight, ii) cumulative feed consumed, iii) anticipated average daily gain, iv) total cost of feed (concentrates and grass), and v) gross profit per cattle. If a portion of the feed is fed as grass, then the model also computes the pasture land required in hectares, based on the forage species
chosen. It is anticipated that the developed model can assist cattle entrepreneurs and farmers in the development of the beef cattle industry in Malaysia.

2012
Khor, S. K. | Khoo, C. K. | Lim, Y. S. | Syed Hussein S. A. | Helen, M. | Chui, I. | Yeoh, N. N. | Abu Hassan M. A.
A trial and pig performance data collection was conducted to evaluate the efficiency of Luodong Bio- Fermentation Treatment Technology with zero discharge effect in a pig close house system at Tanjung Sepat, Selangor. This trial was done to gather and monitor the pig growth performance and the pig acceptance of using the Loudong Bio-fermentation Waste Treatment Technology in close house enviroment. Growth performance of the pigs were monitored by an average daily gain, feed conversion ratio, behaviour and veterinary observations. Close house temperature, moisture measurement and
bedding sampling were also conducted.
