Bangladesh Agricultural University or BAU was established as the only university of its kind in Bangladesh in 1961. The scheme for the establishment of BAU was finalized on 8 June 1961 and its ordinance was promulgated on 18 August 1961. With the appointment of its first Vice-Chancellor, the university formally came into existence on 2 September 1961 and started functioning with the College of Animal Husbandry and Veterinary Science at Mymensingh as its nucleus. The university has six faculties and 43 departments covering all aspects of agricultural education and research.BAU is the second highest budgeted public university in Bangladesh for the year 2013-2014. BAU's unparalleled research in agriculture has made it very recognized university in whole ASIA continent. Having a very low ratio of teacher-student, quality of education in BAU is brilliant and remarkable. Wikipedia.

The present study investigated the effect of salicylic acid (SA) on toxic symptoms, lipid peroxidation, reactive oxygen species generation and responses of antioxidative and glyoxalase systems in rice seedlings grown hydroponically under copper (Cu) stress for 48 h. Exposures of 75 and 150 μM Cu2+ caused toxicity symptoms (chlorosis, necrosis and rolling in leaves), sharp increases in malondialdehyde (MDA), hydrogen peroxide (H2O 2) contents and lipoxygenase (LOX) activity with concomitant reductions of chlorophyll (Chl) and relative water content (RWC). Both levels of Cu decreased ascorbic acid (AsA), glutathione (GSH), non-protein thiol (NPT) and proline contents in roots but rather increased in leaves except that AsA decreased in leaves too. These results together with overaccumulation of superoxide (O 2 •-) and H2O2 in leaves revealed that Cu exposures induced oxidative stress. Contrary, SA-pretreatment (100 μM for 24 h) reduced toxicity symptoms and diminished Cu-induced increases in LOX activity, H2O2, MDA and proline contents while the levels of RWC, Chl, AsA and redox ratios were elevated. Higher levels of GSH and NPT were also observed in roots of SA-pretreated Cu-exposed seedlings. SA-pretreatment also exerted its beneficial role by inhibiting the Cu upward process. Studies on antioxidant enzymes showed that SA further enhanced the activities of superoxide dismutase, ascorbate peroxidase, glutathione reductase and glutathione peroxidase, and also elevated the depressed activities of catalase, dehydroascorbate reductase and glutathione S-transferase particularly at 150 μM Cu2+ stress. In addition, the activity of glyoxalase system (glyoxalase I and II) was further elevated by SA pretreatment in the Cu-exposed seedlings. These results concluded that SA-mediated retention of Cu in roots and enhanced capacity of both antioxidative and glyoxalase systems might be associated with the alleviation of Cu-toxicity in rice seedlings. © 2013 Springer Science+Business Media New York.

Trade in aquatic products is the largest global food sector, by value, and Asia represents the main external source of aquatic products into the EU. Current EU policy supporting international trade between Asia and Europe concentrates on issues of food safety as measures of quality, whilst market-forces drive development of standards and labels that identify social and environmental parameters. This project proposes to establish an evidence-based framework to support current stakeholder dialogues organised by a third party certifier. This will contribute to harmonising standards, helping consumers to make fully informed choices with regards to the sustainability and safety of their seafood. The Ethical Aquatic Food Index, a qualitative holistic measure of overall sustainability to support consumers purchasing decisions, will be based on detailed research centred around a Life Cycle Assessment of current processes involved in ensuring aquatic products reach consumers, aligned with analyses from the sustainable livelihoods approach and systems thinking. SMEs based in the EU will participate in this project, particularly the action research phase, enhancing their relative competitiveness. By strengthening the knowledge base surrounding EU-Asia seafood trade the project will provide the evidence required to support further expansion whilst ensuring a fair deal for producers who are meeting appropriate social and environmental goals and offering a safe and sustainable product for consumers. The sectors covered represent the main aquaculture products reaching EU markets; tilapia, catfish, shrimps and prawns. Known case study stakeholders include SMEs in Bangladesh, China, Thailand and Vietnam where sustainability is essential in the face of rapid growth. The research will secondarily improve understanding of opportunities for European exports to supply the expanding middleclass in Asia. Outputs will be promoted through workshops, websites, journal and press articles.

Discovery of new antimicrobials is highly desired due to the emergence of microorganisms that have multi-drug resistant capability. The purpose of this study was to investigate the antimicrobial effect of dopamine (DA) on Escherichia coli. DA's inhibitory activity was tested at different initial E. coli cell concentrations. Significant 3.5 and 4.2 log inhibitions were observed for 1 × 10 8 and 1 × 10 7 cells per mL, when compared to controls, corresponding to 99.97 and 99.99% inhibitions. Microscopic techniques (optical, fluorescence, and scanning electron) and Fourier transform infrared spectroscopy confirmed a polydopamine coating on the bacterial cells. Capillary electrophoresis with ultra-violet detection indicated a significant change in the cell structure caused by a low dose (100 mg L -1) of DA within 200 min of incubation. © 2012 The Royal Society of Chemistry.

In order to meet the soaring demand for food, there is a need to increase rice and fish production in Bangladesh. In spite of the potential for rice-fish farming, rice monoculture remains the main farming system in Bangladesh. However, rice monoculture cannot provide a sustainable food supply without a cost to long-term environmental sustainability. We provide evidence that integrated rice-fish farming can play an important role in increasing food production as the integrated farming system is better than rice monoculture in terms of resource utilization, diversity, productivity, and both the quality and quantity of the food produced. The Cobb-Douglas production function model also suggests that higher yields can be achieved by increasing inputs in the integrated farming system. Integrated rice-fish farming also provides various socioeconomic and environmental benefits. Nevertheless, only a small number of farmers are involved in integrated rice-fish farming due to a lack of technical knowledge, and an aversion to the risks associated with flood and drought. We conclude that integrated rice-fish farming can help Bangladesh keep pace with the current demand for food through rice and fish production but requires greater encouragement if it is to realize its full potential. © 2011 Springer Science+Business Media B.V. & International Society for Plant Pathology.

Drying is the oldest preservation technique of agricultural products, and sun drying is still widely used for preservation of agricultural products in the tropics and subtropics. Previous efforts on solar drying of cereal grains, fruits, vegetables, spices, medicinal plants, and fish are critically examined. Recent developments of solar dryers such as solar tunnel dryer, improved version of solar tunnel dryer, roof-integrated solar dryer, and greenhouse-type solar dryer for drying of fruits, vegetables, spices, medicinal plants, and fish are also critically examined in terms of drying performance and product quality, and economics in the rural areas of the tropics and subtropics. Experimental performances of different types of solar dryers, which have demonstrated their potentialities for drying of fruits, vegetables, spices, medicinal plants, and fish in the tropics and subtropics, are addressed, and also the simulated performances of the different types of solar dryers are discussed. The agreement between the simulated and experimental results was very good, and it is within the acceptable limit (10%). The simulation models developed can be used to provide design data and also for optimal design of the dryer components. A multilayer neural network approach was used to predict the performance of the solar tunnel dryer. Using solar drying data of jackfruit and jackfruit leather, the model was trained using back propagation algorithm. The prediction of the performance of the dryer was found to be excellent after it was adequately trained and can be used to predict the potential of the dryer for different locations and can also be used in a predictive optimal control algorithm. Finally, prospects of solar dryers for drying of fruits, vegetables, spices, medicinal plants, and fish in the tropics and subtropics are discussed. © 2011 Springer Science + Business Media, LLC.

Dr MAK Azad and his team at the Department of Animal Science, Bangladesh Agricultural University carried out a research project to assess the impact of livestock rearing on public health and environment in some municipalities of Bangladesh. The research, carried out among 90 farmers in the Mymensingh, Gazipur and Shariatpur municipalities, showed that disease outbreaks related to ecto-parasites, mastitis, helminthosis, lumpy skin disease, wounds, and diarrhoea were common to the study area. Although, a categorical link between the disease outbreaks and livestock rearing hasn't been established in the research article, lead researcher Professor Dr MAK Azad claims livestock play a significant role in increasing the risk of diseases. "Most of the disease outbreaks are Zoonotic diseases and Zoonotic diseases are communicated to humans from livestock," says Dr Azad. Dung and urine disposal in public places, malodour and road blockages are other problems created by livestock rearing in urban areas. The problem is aggravated by unmanaged fodder and shelter for the livestock. The research findings have shown that 86% of the livestock were kept in temporal sheds. They also showed that two thirds of the total livestock reared in the urban areas roamed freely on the roadside and fed on garbage, and 79% drank water from drainage lines. The pathogens, heavy metals and other chemicals consumed by the animals pass to humans in the food chain through dairy and meat products. Most (68%) of the livestock reared in the study area are reared for dairy purposes, while 24% were reared for beef. Despite the grave risk to public health and environment, little effort has been made to curb the situation. The law is silent on the issue and there is no database or estimation of how many cattle are reared in the urban areas. "There is no regulation related to banning livestock in urban areas," says Dr Azad. "Moreover, it's mostly the politicians and the "musclemen" that keep the livestock. So nobody can raise a finger against them." Indeed, the research findings show that 58% of the livestock keepers were politicians and 26% were self-employed traders, both powerful sections of the society. That could be the reason why no precautions or care is taken in rearing livestock in a managed way in order to reduce the adverse impact, although most livestock owners had basic education and all of them were aware of the negative impacts of livestock rearing in urban areas. The research showed that 100% of the participants were aware of the adverse effects that livestock rearing would have on public health and environment and 73% had at least primary education. "Serious steps need to be taken to bring this situation under control as it could invite uncontrollable epidemics if it goes unchecked," says Dr Azad. The rise in the urban population in Bangladesh has increased pressure on the already-strained city infrastructure and job market. Poverty is moving to the cities from the villages. Many urban dwellers are using livestock rearing for beef and dairy as an additional income source to meet their growing needs at the cost of public health and environmental hazards. In his next research on a related topic, Dr Azad says he has found the presence of heavy metals like mercury, lead, chromium and manganese in animal products. The article "Impact of livestock rearing practices on public health and environmental issues in selected municipality areas of Bangladesh" appears on a recent issue (Vol. 45(1), 2016) of Bangladesh Journal of Animal Science, pages 44-51.

Sediment has been released from the dams of many rivers throughout the world to keep reservoirs operational. This huge flux of sediment resulted in deposition in downstream channels and bars and was followed by an intensive colonization of plants. An investigation was carried out to clarify the relationship between the colonization of herbaceous vegetation and a set of edaphic factors observed in downstream active river channel areas of the Kurobe River in Japan that were subject to different rates of deposition. Herbaceous plant biomass was strongly correlated (p< 0.01) with surface sandy layer thickness. It had also a high correlation with a fraction of fine sediments (p< 0.01). However, higher plant biomass due to fine sediment was associated with its total nitrogen (TN) concentration rather than total phosphorus (TP) or moisture content levels. The TN:TP ratio of substrate was smaller than that of the plants and suggests that the lack of nitrogen (N) was the primary factor for limiting plant growth. Following sediment release, N was no longer a limiting factor and as a result, vegetation growth was promoted. The increased depth of fine sediment in these areas also favored vegetative encroachment. Over 90% of TN and TP in the substrate were organic and originated from the nutrients that were in the sediment accumulated in the reservoir. The accumulation of sediment also changed the inundation pattern of the river channels and frequently submerged transects that were more fertile and productive for herbaceous plants as opposed to less inundated, higher spots, which represent the original unaffected portion of the river. After initial colonization, the encroachment of vegetation was accelerated by the intensified accumulation of fine sediment during inundation and added nutrients through litter mineralization. The history of sediment release in the Kurobe River and the rate of encroachment of channel vegetation follow a similar trend. The results of this study support the hypothesis that the downstream river channel morphology and ecosystem shift considerably due to multiple dam releases and create a substantial amount of sediment deposition that favorably change the nutrient stoichiometry and allow for vegetative encroachment. Therefore, any nutrient release program should consider the measurable costs and benefits when it comes to these releases and the amount of vegetative growth in these channels that result. © 2012 Elsevier B.V.

Organic acids and their salts have been approved by European legislation as an alternate source of antibiotic growth promoter in diets, because antibiotics are associated with problems due to potential residual effects via food animals developing resistant strains of pathogens. Citric acid (CA) is a weak organic acid which is a natural preservative and can add an acidic or sour taste to foods and soft drinks. It exists in small amounts in a variety of fruits and vegetables, most notably citrus. Penicillium mould and Aspergillus niger could be efficient CA producers on a commercial basis. Its inclusion in animal diets has been reported to decrease colonisation of pathogens and limit then production of toxic metabolites, improve availability of protein, Ca, P, Mg and Zn as well as serve as a substrate in intermediary metabolism. Its addition in drinking water is not promising for performance, but lower doses would be useful for sanitary aspects and gut health. Its inclusion at 0.5% in the diet improves performance and non-specific immunity of broilers. It also enhanced specific immunity against new castle disease in vaccinated broilers. Current data supports a recommendation in the broiler diet up to 0.75% in pelleted feed and 0.5% in mash diets, with a safety margin of 6.0%. Additional research is needed to determine the feasibility of its use in low nutrient density broiler diets. © World's Poultry Science Association 2012.

Veterinary Parasitology | Year: 2012
Cryptosporidiosis is a common gastro-intestinal illness in animals and man worldwide. The disease is devastating in immune-suppressed individuals but self-limiting in competent hosts. The infectious stages of the organism (oocysts) are shed in the faeces of affected individuals, survive in adverse environmental conditions and spread by direct contact or through contaminants (food, water). Due to the robustness of the oocysts, their tenacity, tiny size, and resistance to common disinfectants, the parasite is difficult to eradicate from contaminated environments. To obtain sufficient control both treatment of infected hosts and inactivation of oocysts are necessary. Several drugs are commonly used to treat cryptosporidiosis in man and very few in animals but none of them are completely effective in terms of both clinical and parasitological response. Only a few chemical agents are able to inactivate oocysts in the environment including water treatment plants but their application has certain limitations. Therefore, control of cryptosporidiosis remains a global challenge in both veterinary and human medicine. Extensive research has been performed on suitable drugs and disinfectants. Thousands of agents have been tested both in vivo and in vitro. Some are excitingly active in vitro but exhibit poor or no response in clinical trials. Currently, no single or combined drug therapy has proven to be completely effective against this disease. This article will focus on therapy and prevention of cryptosporidiosis in animals including perspectives for new drugs. © 2012 Elsevier B.V.
