Summary: Botanical products are increasingly being used in poultry farms as natural and safe alternatives for producing organic products. These products can improve bodyweight, egg production, meat, egg quality, and rooster semen quality in poultry, attracting attention from scholarly groups and the general population. Previous research mainly focused on growth promotion, anti-inflammatory, and antibacterial effects, while current reviews explore the critical effects and functions of bee products and botanicals as feed additives in poultry production.

Summary: The study investigated the impact of biocides and nanoparticles on microbial diversity in a hydraulic fracturing impacted stream. The results showed that different types of nanoparticles led to a decrease in bacterial abundance, while biocide-amended treatments saw an increase in microbial abundance. Differentially enriched taxa were observed in biocide and nanoparticle treatments compared to controls, indicating that nanoparticles slightly altered the microbial community composition. The study suggests the potential use of nanoparticles as an alternative to biocides in certain settings.

Summary: The increase in drug resistance and ineffective immunization against pathogens pose a significant threat to the poultry industry. Spirulina, a natural ingredient rich in nutrients and antioxidants, can beneficially affect gut health and disease resistance in chickens. It has antibacterial effects and can also exhibit antiviral activities against common human or animal viruses. Additionally, Spirulina can modulate the immune system, improving disease resistance and growth rates in poultry. This review discusses the potential use of Spirulina as a dietary supplement to enhance growth, gut health, and disease resistance in poultry.

Summary: Small-scale farming of meat chicken flocks using local native breeds is important for the economy in rural areas of Vietnam and LMICs, but there is limited knowledge on the profitability and sustainability of these systems. Feed is the largest financial cost for these farms, and a significant portion of farms decide to stop raising chickens after one cycle due to higher costs and mortality rates. Supporting farmers with advisory services and training in the early stages can help improve profitability and reduce the risk of antimicrobial resistance and infectious disease emergence.

Summary: After administration of antimicrobials, poultry excrete high concentrations of antimicrobials in their droppings, which accumulate in poultry litter widely used as agricultural fertilizer. A method to identify different antimicrobial families in poultry litter was developed using HPLC-MS/MS, detecting nine compounds reliably. This method provides a valuable tool for monitoring antimicrobial residues in poultry litter and controlling its use in agriculture.

Summary: Many pathogens commonly infect birds through the respiratory tract, leading to respiratory disorders and significant financial losses in the poultry industry. Viral pathogens, such as avian influenza virus, Newcastle disease virus, infectious bronchitis virus, and avian pneumovirus, are particularly severe. Bacterial pathogens, including Mycoplasma gallisepticum, Staphylococcus, Bordetella avium, Pasteurella multocida, Riemerella anatipestifer, Chlamydophila psittaci, and Escherichia coli, also cause serious respiratory infections in poultry. This review provides an updated summary of the evidence for widespread poultry respiratory pathogens, along with possible control and prevention methods.

Summary: The study investigated the prevalence of highly pathogenic avian influenza (HPAI) virus in commercial broiler chicken flocks from 2019 to 2022. Samples were collected from 111 problematic flocks and analyzed using molecular tools. The results showed that 21.6% of the flocks tested positive for HPAI H5N8, with higher prevalence in vaccinated flocks and detection mainly in autumn and winter. Regular molecular monitoring, vaccine efficacy evaluation, and preventive strategies are recommended to control this serious threat.

Summary: Leachate usually contains toxic pollutants such as organic and inorganic compounds, heavy metals, and contaminants. It is crucial to carefully manage landfill leachate in order to reduce its quantity and prevent contamination. Lack of cost-effective treatment technology and disposal guidelines by municipalities contribute to the ecological and health impacts of leachate in developing countries. This review discusses the classification, composition, production factors, and treatment options for leachate, including aerobic and anaerobic biological treatment and physiochemical management processes.
