Aug 28, 2023 · Layering and turning the compost pile is crucial for composting chicken waste. Begin with a base layer of carbon-rich materials to establish a solid foundation. Gradually add chicken waste and other nitrogen sources in thin layers. To maintain a balanced mixture, incorporate additional carbon materials. Regularly turning the compost pile
Feb 1, 2022 · In addition, studies have also investigated that the succession and evolution of heavy metal resistant bacteria during composting (Zhou et al., 2021; Liu et al., 2021), which revealed heavy metal resistant bacteria played an important role in improving composting quality and efficiency. However, response strategies of microbial community to
Mar 15, 2023 · The results showed that thermophilic composting was effective at reducing the majority of the spreading risk of antibiotic resistance by 1) eliminating more than half of allARGs that accounted for 80% of the total abundance, 2) reducing the number and abundance of high-risk ARGs significantly, and 3) removing the ARG hosts and the pathogenicity
This study explored the combined effects of Bacillus subtilis inoculation with biochar on the evolution of bacterial communities, antibiotic resistance genes (ARGs), and mobile genetic elements (MGEs) during the composting of chicken manure. The results showed that B. subtilis inoculation combined w
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.
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Jan 1, 2024 · The composting materials and composting operations were similar to those described by Tang et al. (2019) and Fu et al., (2022a). Composting experiments were carried out using three composting systems (EFAC, CAC, and CCMC) using the material mix proportions (Table 1). An electric field with a DC voltage of 5 V was applied to the compost in the
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.
Jun 1, 2017 · However, the effects of BC on antibiotic resistance genes (ARGs) during chicken manure composting are still unclear. This study investigated the effects on ARGs of adding different proportions of BC (0%, 5%, 10%, and 20% w/w) to chicken manure compost.
Apr 1, 2023 · 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.
Apr 1, 2024 · The experiment was conducted within a composting reactor with a capacity of about 15L and a ventilation function. According to the temperature trend, the composting process was divided into four phases (Wang et al. (2023)c). In order to ensure uniformity in the sampled material, a five-point sampling method was implemented on days 0, 3, 8, 13
Jun 13, 2023 · Poultry waste can be produced into high-quality organic fertilizers by composting. In this project, a microbial agent was constructed. The objective of this study was to analyze the effectiveness of additives (microbial agent (TB) and manure compost (TM)) on composting process of chicken litter with mushroom residue. Results indicated that TB exhibited the highest composting temperature (72.1
Jun 15, 2022 · 1. Introduction. Globally, more than half of all antibiotics produced are used in animal husbandry (Van Boeckel et al., 2017; Wang et al., 2019).The larger amount of antibiotics utilization produced selective pressure for microbe in livestock fermentation systems to obtain and remain antibiotic resistance genes (ARGs), and the resistant ability was fostered gradually by the enrichment of the
Dec 3, 2012 · Whenever you have more compost material, add it to the pile. If the pile starts to get really compacted or the chickens show little interest in digging in it, throw some scratch grains on it. Even if they don’t initially show interest, they will once the pile starts getting more biologically “active”.
