Feb 14, 2024 · Livestock manure management plays a crucial role in mitigating GHG and air pollutant emissions associated with the livestock sector (Zhang et al., 2020a).A successful manure management system should not only reduce the pollutant gas emission, but also consider the economic cost and technical feasibility (Li et al., 2021).
Nov 1, 2021 · The formula used to calculate the theoretical potential of biogas is as follows (2) (Abdeshahian et al., 2016): T P B = M × T S × E B T S (2) where T P B is the theoretical potential of biogas (m 3 year −1); M is the total amount of manure; and T S is the ratio of the total solids of animal manure—i.e., 25% for cattle, pigs, and sheep
Jul 31, 2019 · Nine anthropogenic sources are used including fossil fuel (industry), waste treatment and landfill, rice cultivation, livestock enteric fermentation, manure management, and four pyrogenic sources
Jul 15, 2022 · This experiment contained 3 steps. During straw feeding, beef cattle were allocated into 2 groups and fed diets with or without monensin, respectively. During fermentation, beef cattle manure (with or without monensin) and straw (corn or wheat) and were co-fermented for 35 d to produce substrates.
Jul 1, 2023 · We hypothesized that microbial inoculation could optimize microbial community, thereby affecting DOM derivation and related components variation in the fermentation system. Therefore, we performed industrial-scale aerobic fermentation of livestock manures with microbial inoculation.
Sep 1, 2021 · PDF | On Sep 1, 2021, Jiamin Zhao and others published Effects of Exogenous Biochar Addition on High Solid Anaerobic Fermentation of Livestock Manure for Environmental Pollution Control | Find
Jul 15, 2022 · Although crop-livestock integration recycling systems improve nitrogen (N) utilization in agroecosystems, there are limited studies regarding impacts of residual antibiotics in livestock manure on N transformation in entire recycling system. The objective was to evaluate effects of feeding monensin
Oct 8, 2020 · In this regard, the aim of this work was to achieve the production of biogas using the dry anaerobic technology through livestock manure co-digestion with agricultural waste (AW) such as potato peels, lettuce leaves and peas peels. The manure and AW were mixed at a ratio of 2:1 for 15 min before being introduced into the batch anaerobic system.
Jul 27, 2023 · Conversion of livestock manure into organic fertilizer is a sustainable strategy in crop production. In contrast to composted manure, the agronomic characteristics of an anaerobic digestion by-product, digestate, have not been well characterized. This study aimed to investigate the effects of digestate and compost, derived from a pilot-scale livestock waste recycling system, on bioactive
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
Apr 2, 2024 · We used microbiology and molecular biology techniques to screen out high-temperature and low-temperature-resistant saprobiotics for compost and prepared a compound fermentation bacteria agent to rapidly ferment cattle manure into high-quality organic fertilizer in low-temperature season.
Jul 27, 2023 · Due to intestinal fermentation in ruminants and the production of manure, the livestock industry is widely regarded as one of the largest contributors to CH 4 emissions. In this chapter, practical for reducing the emissions of GHGs from livestock manure were examined.
Jun 3, 2017 · Overproduction of livestock manures with unpleasant odors causes significant environmental problems. The microbial fermentation bed (MFB) system is considered an effective approach to recycling utilization of agricultural byproducts and pig manure (PM).
Jan 14, 2021 · In order to achieve harmless and resourceful utilization of livestock manure, anaerobic fermentation is the most extensive treatment method in the world. And the effects of antibiotics on the ...
