Feb 15, 2022 · Volume 139, 15 February 2022, Pages 124-135. Integral approach for the evaluation of poultry manure, compost, and digestate: Amendment characterization, mineralization, and effects on soil and intensive crops.
Jun 1, 2017 · The increasing emergence and spread of antibiotic resistance genes (ARGs) have become major global public health issues in recent years (WHO, 2014, Wright, 2010). Antibiotics are used widely by the livestock industry, so animal manure is considered to be an important reservoir of antibiotics and ARGs (Heuer et al., 2011, Zhu et al., 2013).
Nov 12, 2021 · Traditional chicken manure fermentation is mostly natural composting or exposure, which is not only time consuming but also susceptible to weather, resulting in uncontrollable quality and environmental pollution. This research aims to build a smart solar chicken manure fermentation system to control the conditions of chicken manure fermentation effectively, improve quality, and solve the
The study focuses on the following: (1) biochar and hydrochar production under different process conditions for production of carbon-rich fuel from poultry manure; (2) phosphorus recovery by acid leaching–alkali precipitation from manure ash, biochar, and hydrochar; and (3) activated carbon production from acid-leached hydrochar and biochar.
Feb 24, 2023 · A systematic review was conducted to summarize and synthesize the existing research on poultry farmers' knowledge, practices, and awareness regarding antimicrobial use (AMU) and antimicrobial resistance (AMR). It was undertaken by systematically searching databases, screening and characterizing relevant studies, extracting data, and evaluating the risk of bias. The outcomes were stratified
Providing anaerobic digestion is a prospective technology for utilizing organic waste, however, for waste with a high content of nitrogen such as manure, dilution is necessary to decrease the ammonia inhibition effect which leads to the production of a huge effluent amount which is difficult to use. Dry anaerobic digestion has some advantages such as reduced reactor volume, higher volumetric
Dec 1, 2019 · Furthermore, tet (G) was the most common resistance gene identified in tetracycline-resistant E. coli O157:H7 isolated from feedlots in the USA (Wilkerson et al., 2004). Unrestrained use of tetracyclines in intensive poultry production leads to the emergence of bacterial resistance due to selective action ( Singer and Hofacre, 2006 ).
May 6, 2021 · Distribution of Antibiotics and Antibiotic Resistance Genes in Animal Manure. The environmental pollution caused by antibiotics and their ecotoxicological effects has become a major global problem, especially the environmental pollution caused by the abuse of antibiotics in the livestock and poultry industry [5,6,7,8], which has become one of the current international research hotspots [].
Jul 24, 2020 · Promotion of intensive poultry production could increase antimicrobial resistance (AMR) within resource-limited settings lacking in effective biosafety and biosecurity measures. Bacterial resistance lessens the portfolio of antimicrobials available in poultry husbandry and potentially human medicine.
Mar 30, 2020 · @article{Zainudin2020BiocharET, title={Biochar enhanced the nitrifying and denitrifying bacterial communities during the composting of poultry manure and rice straw.}, author={Mohd Huzairi Mohd Zainudin and Nurul Asyifah Mustapha and Toshinari Maeda and Norhayati Ramli and Kenji Sakai and Mohd Ali Hassan}, journal={Waste management}, year={2020
Jul 22, 2020 · The prevalence of antibiotic resistance genes (ARGs) in animal manure poses a threat to environmental safety. Organic fertilizers fermented by livestock and poultry manure are directly applied to farmland and have the potential to cause outbreaks of bacterial resistance in agricultural environments.
Nov 1, 2018 · In this study, the bacterial community succession and variations were investigated in poultry manure (PM) compost by the using high-throughput sequencing in six different concentration of clay [at 0% (T1), 2% (T2), 4% (T3), 6% (T4), 8% (T5) and 10% (T6) on PM dry weight basis] applied compost.
Aug 13, 2020 · Resistance determinants can be transferred from animal to animal or animal to human either directly via contact, or indirectly through the food chain, water, sludge-fertilized soils and manure. The human transmission of antibiotic-resistant bacteria and ARGs from agricultural sources is mostly foodborne .
Jun 12, 2023 · Adopting waste-to-wealth strategies and circular economy models can help reduce biowaste and add value. For instance, poultry farming is an essential source of protein, and chicken manure can be converted into renewable energy through anaerobic digestion. However, there are a number of restrictions that prevent the utilization of chicken manure in bioenergy production. Here, we review the
Jan 27, 2024 · Inputs such as irrigation water and poultry manure used in lettuce cultivation have been found to be associated with antibiotic-resistant pathogens. The study assessed the antibiotic resistance profile of Escherichia coli isolated from lettuce, poultry manure, irrigation water, and soil in Kumasi. One hundred and fifty-six samples of lettuce
