cattle manure large scale composting equipment enhanced corrosion resistance

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.

Jun 5, 2021 · Livestock manure is a major source of antibiotic resistance genes (ARGs) that enter the environment. This study assessed the effects of inoculation with mature compost (MC) on the fates of ARGs and the bacterial community during swine manure composting.

Jul 21, 2023 · As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate waste management can contribute to environmental pollution. This study seeks to optimize small-scale composting systems to address the inefficiencies and the limited automation of traditional composting equipment. We redesigned the mixing blades and refined the ventilation

Sep 4, 2017 · Manure in intensive farming should be composted before being discharged into the field, while grazing livestock manure is not suitable for composting due to an increased number of resistance genes

Oct 5, 2018 · -Cattle, poultry, and swine manure mixed with rice straw.-Large-scale commercial composting. No-Abundance of antibiotic resistance genes in raw cattle and poultry manure: 1.9 and 5.5 copies/cell.-Abundances in the final cattle and poultry mature composts : 0.2 and 1.8 copies

Apr 20, 2023 · With the growing concerns about antibiotic resistance, it is more and more important to prevent the environmental pollution caused by antibiotic fermentation residues. In this study, composted erythromycin fermentation residue (EFR) with the mixture of cattle manure and maize straw at ratios of 0:10 (CK), 1:10 (T1), and 3:10 (T2) explores the effects on physicochemical characteristics, mobile

Aug 18, 2023 · The study describes the analysis of antibiotic‐resistant bacteria (ARB) abundance and the overall bacterial diversity of cattle farm soils that have been treated with animal manure compost. Our results showed that ARB abundance was greatest in fresh manure and significantly lower in composted manure.

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 of ARGs were assessed during manure composting. Results showed that the total relative abundances of ARG

Jul 27, 2023 · This study provides compelling evidence that the cow manure composting equipment proposed herein significantly enhances the efficiency of livestock manure composting while yielding high-quality organic fertilizer.

Key words: dairy manure compost, antibiotic-resistant bacteria, antibiotic resistance genes, microbial community diversity INTRODUCTION China has become one of the major livestock- and poultry-producing countries in the world. Because of the large production scale, more than 4 billion tons of livestock and poultry manures are produced and dis-

Sep 1, 2022 · A large-scale study involving data from 28 composting systems fed from commercial pig farms showed that reactor composting had the best results in terms of material degradation, nitrogen loss, antibiotics, and antibiotic resistance genes compared to conventional such static heap and windrow systems (Awasthi et al., 2019c, Awasthi et al

Mar 6, 2024 · Our results demonstrate that composting reduced more high-risk resistance genes at the transcriptomic level in cattle manure than conventional stockpiling. This finding not only underscores the effectiveness of composting in reducing antibiotic resistance in manure but also highlights the importance of employing RNA analyses alongside DNA analyses.

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

Nov 1, 2017 · Composting and anaerobic digestion are the main treatment means of livestock manure Liu et al. 2021). Composting has the characteristics of simple operation and is environmentfriendly, so the
