Apr 1, 2023 · Antibiotic residue in husbandry waste has become a serious concern. In this study, contaminated chicken manure composting was conducted to reveal the bioaugmentation effect on tetracyclines residue and antibiotics resistance genes (ARGs). The bioaugmented composting removed most of the antibiotics in 7 days.
Jul 21, 2023 · The upgraded composting equipment’s improved mixing structure, ventilation heating system, and automation level ultimately contributed to the enhanced efficiency of livestock manure composting and increased the utilization value of the resulting organic fertilizer.
With the implementation of ‘Livestock and Poultry Manure Utilization Action Plan (2017−2020)’ policy in 2017 in China, the composting practice had been adopted for livestock and poultry manure utilization [2]. Results of recent studies demonstrated that composting was a viable approach for organic matter stabilization and sanitization [10].
Dec 14, 2020 · Moreover, concerns about the potential for manure to act as a vehicle for the transmission of antibiotic-resistant bacteria or genes to agricultural soils or crops means that there is a growing interest in identifying to reduce resistant populations in manure. Temperature changes during composting (a) and stockpiling (b) of beef cattle
Feb 1, 2022 · Heavy metal pollution was the main risk during livestock manures composting, in which microorganisms played a vital role. However, response strategies of microbial community to heavy metals stress (HMS) remained largely unclear.
Nov 1, 2023 · Agriculture and Carcass Disposal. Carcass disposal is an important consideration for livestock farming. Proper disposal of carcasses is important to prevent transmission of livestock disease and to protect air and water quality. Typical for the disposal of animal mortalities have included rendering, burial, incineration, and composting
Composting is more than just piling the mate-rial and letting it sit, however. Composting is the active management of manure and bedding to aid the decomposition of organic materials by micro-organisms under controlled conditions. Efective composting is afected by four major factors: Aeration. Nutrient balance.
Jan 1, 2024 · Co-composting of kitchen waste and chicken manure reduces the pH of compost pile. • Electric field-assisted aerobic co-composting (EFAC) mitigated NH 3 emission. • EFAC promotes organic matter humification and increases compost maturity. • EFAC provides a feasible idea for the resourceful disposal of mixed organic wastes.
Turning manure is essential to composting manure. Turning compost incorporates oxygen into the system, homogenizes the pile and breaks up clumps. Turning allows more contact of manure with microbes. Producers have various ways to turn the pile. The two most common for turning compost are with a windrow turner (Figure 7) or bucket tractor.
Composting livestock and poultry carcasses. Quick facts. Composting is an approved method for disposal of poultry, swine, cattle, horses, sheep, goats and farmed deer. Always check with local authorities to understand local rules and processes before starting a mortality compost system.
Application of RSC allows CM to produce mature, safe organic fertilizer after 32 d and reduces the risk of rebound from ARGs, but the issues of sul1 and ermC gene removal cannot be ignored. Keywords: Antibiotic resistance gene; Bacterial community; Chicken manure; Composting; Heavy metal passivation.
Sep 1, 2021 · Aerobic composting is commonly used to dispose livestock manure and is an efficient way to reduce antibiotic resistance genes (ARGs). Here, the effects of different quality substrates on the fate
Feb 1, 2024 · DOI: 10.1016/j.cej.2024.149581 Corpus ID: 267717707; Electrokinetic technology enhanced the control of antibiotic resistance and the quality of swine manure composting @article{Li2024ElectrokineticTE, title={Electrokinetic technology enhanced the control of antibiotic resistance and the quality of swine manure composting}, author={Binxu Li and Muhammad Fahad Sardar and Xu Zhang and Jing Ye and
Abatement of antibiotic resistance genes (ARGs) in livestock manure by composting has attracted attention. This study investigated the effect of adding magnesium-modified biochar (MBC) on ARGs and microbial communities in chicken manure composting. Twelve genes for tetracyclines, sulfonamides, and m
Apr 1, 2024 · Abstract. Chicken manure (CM) can pose a serious threat to environmental and human health, and need to be managed properly. The compost can effectively treat CM. However, there is limited research on the heavy metals and antibiotic resistance genes (ARGs) during compost CM.
