This review paper focuses on the current state of poultry waste generation, composition, and management techniques in commercial poultry farms and trading in Bangladesh, to reduce pol¬lution and generate economic benefits from poultry waste. It also underlines the negative impact of poultry waste disposal on the environment. In Bangladesh, collection of poultry waste into bags and, subsequently, direct use as fertilizer in agricultural fields and aquaculture is common, while alternative disposal methods such as composting and biogas generation are now attracting commercial poultry producers. Direct use of poultry manure results in poor air and soil quality, environmental deterioration, detrimental effects on global health, climate change due to high levels of atmospheric ammonia, and the creation of significant amounts of greenhouse gases. Lack of knowledge and investment, as well as high demand for free land for composting, are important obstacles. Future research on precise waste characterization improved understanding of poultry waste management, and increased efforts on developed waste disposal for a safe environment are therefore recommended. So, poultry waste, which is currently a burden on the environment, could be turned into a useful agricultural resource, which would be useful for the poultry industry.
For rapid and sensitive pathogen screening from field outbreaks, molecular techniques such as qPCR-based simultaneous detections are efficient. Respiratory diseases are the most detrimental diseases to the poultry industry and need to be addressed because of their major economic losses. In the current study, we have applied two different detection assays: one for simultaneous detection of avian influenza virus (AIV; M gene) and subtyping (H5, N1, H9, N2) using TaqMan probe chemistry (TaqMan multitarget) and another for simultaneous detection of Newcastle disease virus (NDV), infectious bronchitis virus (IBV), and infectious laryngotracheitis virus (ILTV) using SYBR Green chemistry (SYBR Green multitarget). Two individual qPCRs were conducted for the detection of four pathogens. Surveillance of tissue (n = 158) and oropharyngeal swab (206) samples from multiple poultry flocks during the years April 2020–July 2022 applying the TaqMan and SYBR Green multitarget qPCRs revealed that 48.9% of samples were positive for respiratory infections, of which 17.2% were positive for NDV, 25.5% were positive for AIV, 9.9% were positive for IBV, and only a single positive (0.3%) for ILTV. Among the AIV, 35% were highly pathogenic subtype H5N1 and 65% were low pathogenic subtype H9N2. Co-infections of 2–3 respiratory viruses were also accurately detected. Respiratory viral pathogens are quite common in Bangladeshi poultry and can be successfully detected using multitarget simultaneous real-time quantitative polymerase chain reaction (RT-qPCR) assays like those adopted in the current study. Increased mass surveillance, along with the molecular characterization of the circulating respiratory viruses, is crucial to control the epidemic and subsequently save the Bangladeshi poultry industry.
The study was conducted to assess the level of farm mechanization technology utilization in poultry production in Chukun and Igabi Local Government Areas, Kaduna State. Purposive sampling was used to select wards, multi-stage to choose villages and simple random to pick 140 responding farmers. Frequency distribution, percentages and means were the analytic tool used. Majority of the producers (75%) were aged forty years and below. All the producers had formal education. More than half of the producers (65%) were in poultry. About 57% were non-members of cooperatives. The major source of technology (68%) was local market. Majority of the producers (79%) adopted hand tool technologies. A few of the producers (18%) adopted battery cage, (4%) feed mill and (4%) incubator. The benefits of the technologies were 36% proper use of space, 21% easy handling of large flocks, 18% decrease in cost of production. The constraints were 46% inadequate access to capital, 18% lack of electricity and water and 14% poor extension contact. Majority of the producers adopted hand tools and were non-members of cooperatives thus could not enjoy economies of scale. Provision of adequate fund to producers and formation of cooperative were recommended.
