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.
Aug 18, 2023 · Collectively, these results suggest that the transfer of antibiotic resistance from composted animal manure to soil may not be solely mediated through the application of live bacteria and highlight the need for further research into the mechanism of antibiotic resistance transfer.
Mar 15, 2023 · Thermophilic composting reduced the bulk antibiotic resistance in animal manure. • Bacterial community succession drove the attenuation of ARGs. • Plasmid-associated ARGs rebounded via horizontal gene transfer during cooling phase. • Ratios of high-risk ARGs and plasmid-associated ARGs increased during composting. •
Oct 1, 2023 · Though, the great costs of these techniques restrain their widespread use in livestock husbandry. In addition, anaerobic tanks, as the most- frequently applied treatment practices, have been exhibited to stimulate the growth of antibiotic-resistant bacteria (ARB) and increase the sustainability of ARGs [10]. Thus, to avoid environmental
Jan 13, 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
Mar 1, 2022 · @article{Deng2022DeodorizationOT, title={Deodorization of the off-gas from livestock manure aerobic composting tank using biotrickling filters and its mechanism}, author={Longhua Deng and Jiaxing Xu and Yuxin Li and Shangquan Wu and Kecheng Yi and Ruizhi Dai and Songgui He and Yanbin Xu}, journal={Biochemical Engineering Journal}, year={2022
Jun 22, 2022 · One way to increase yields in agriculture using organic alternative is the introduction of manure-based composts into the soil. However, the use of such composts carries a risk of soil contamination with antibiotic resistance genes (ARG) from the gut and manure of the livestock. The contamination of the composts with heavy metals or antibiotics can increase this risk, while the
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
Mar 15, 2022 · Antibiotic resistance genes (ARGs) have become a global concern for causing serious ecological environmental problems and public health risks. Livestock systems have drawn increasing attention in recent years for a massive consumption of antibiotics and heavy metals (HMs) and become one of main pollution sources of ARGs to aquatic and terrestrial environments. Generally, the generation
Jul 27, 2021 · ABSTRACT. Manure storage can affect the concentration and prevalence of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in cattle manure prior to land application. The objective of this study was to compare stockpiling and composting with respect to their effectiveness in reducing ARB and ARGs in beef cattle
Antibiotic resistance genes (ARGs) are emerging pollutants that enter the farm and surrounding environment via the manure of antibiotic-treated animals. Pretreatment of livestock manure by composting decreases ARGs abundance, but how antibiotic residues affect ARGs removal efficiency remains poorly
Feb 1, 2024 · Furthermore, heavy metal elements were used as livestock forage additives including copper (Cu) and zinc (Zn), and have been extensively identified in livestock manure due to their incomplete assimilation in livestock (Peng et al., 2022; Zhou et al., 2016), not only promoting the occurrence of heavy metal resistance genes (HMRGs) but also
Livestock and husbandry manure compost tank Organic waste such as poultry manure and animal carcasses such as chicken, pig, cow and sheep manure can be processed and turned into usable organic fertilizer
Aug 1, 2021 · Livestock manure has been identified as a significant hotspot for antibiotic resistance genes (ARGs). However, the impact of nanoscale zero-valent iron (nZVI) on the fate of ARGs during livestock
Dec 7, 2023 · 2022/11/21/ · In order to improve the cathodic protection and wear resistance of cold spraying Zn-based coatings, Zn–Ni/Cu–Al2O3 composite coating was prepared by co-depositing Zn powders, nickel-coated Cu powders, and Al2O3 powders on the steel substrate using the low-pressure cold spraying method.
